General Solar System Questions:

Solar cells in panels mounted on your RVs roof converts sunlight into Direct Current (DC) electricity. Batteries store this electricity so it is ready for use at any time. An inverter can convert the DC electricity into Alternating Current (AC) electricity that you can use at your RVs power points. You do not need an inverter if you only want 12V power.


  • The biggest advantage is the independence you will acquire from not being reliant on mains power when travelling. It will give you the freedom to go wherever you want for however long you want.
  • It will add re-sale value to your RV.
  • Solar power is quiet unlike generators.
  • You will save money by avoiding tourist/caravan park fees for powered sites. With electricity prices continually rising so will tourist/caravan park fees. With solar power you have the option of a less expensive unpowered site or staying at a more remote location.
  • If you enjoy quiet locations without a crowd then solar power will let you enjoy outback isolation while still enjoying all your RV luxuries.
  • You can contribute to reducing the impacts of fossil fuel power stations such as greenhouse gas emissions and air pollution.
  • You will be using a clean energy that doesn’t emit fumes, pollution or carbon dioxide into the atmosphere.
  • The components are long lasting, durable and low maintenance. For example solar panels typically produce energy for at least 25 years with no maintenance other than the occasional clean off with water.
  • We are lucky in Australia that we have a high degree of sunshine which makes solar power a worthwhile option. The Australian continent has the highest solar radiation per square metre of any continent and consequently some of the best solar energy resource in the world (GeoScience Australia www.ga.gov.au).


Generally yes although it does depend on where and when you use your caravan/ RV (location of travel and time of year) and how much power you consume each day.

Sizing the system for the worst case scenario of an average winter day in Launceston is unlikely to be cost effective or practical. There is a greater than five-fold difference in the amount of solar energy per unit area between an average sunny summer day in Geraldton and an average winter day in Launceston. In Melbourne for example; an average summer day has more than three times the solar energy per unit area in mid-summer than in mid-winter. This is based on insolation data (solar intensity over a day) generated by a computer model held by the Bureau of Meteorology (http://www.bom.gov.au/climate/austmaps/about-solar-maps.shtml). Data for a number of places, around Australia, including Geraldton, Launceston and Melbourne, is available from Sustainability Victoria

This depends on what your needs are.

We have designed a Solar Power Estimate Calculator (SPEC) that lets you work out how much electricity you would regularly use and what your power needs are. Based on this we recommend a solar system kit that meets your consumption needs. Go to the ‘Assess your needs’ page of this website.

No. Our solar systems convert sunlight into electric current to operate appliances and lights. This is different to the products with solar thermal panels that involve water circulating through tubes to be heated by the sun for water heating.

Solar panels take light from the sun and make electricity. Solar hot water systems take heat from the sun to heat water.

Solar 4 RVs provides complete solar power kits with all-you-need for installation including:

  • Solar panels to collect the sun’s rays. The solar panels are connected together and the output from the panels is fed into batteries via a solar charge controller.
  • A solar charge controller (sometimes also called a solar regulator) converts the solar power from the panels to charge the batteries. It also displays how much power is being generated throughout the day.
  • Batteries that store the solar power ready for when you need it. At night solar panels will not produce any electricity as they require sunlight so batteries store the electricity allowing you to use it when you want, such as in the evenings.
  • An inverter that converts battery voltage to 240 volts so it can be used at your power points. It also provides information such as the amount of power being used.
  • Installation components such as a fuses, cables and polyurethane sealant. The comprehensive installation instructions are simple to understand and supported with diagrams, photos and videos.

Yes. We source the latest quality products that are designed specifically for caravans and recreational vehicles, ensuring they are lightweight, robust and efficient. The ‘Our Products’ page describes the benefits of the components we use such as Lithium Iron Phosphate (LiFePO4) batteries, Maximum Power Point Tracking (MPPT) solar charge controllers and the thin, semi-flexible Monocrystalline Photovoltaic (PV) solar panels that attached to the roof using a polyurethane adhesive sealant.

We recommend that the batteries are placed at floor level above the axle(s) which avoids changing the tow ball weight and worsening pitching (front lifts or descends in relation to the back) and yawing (deviating temporarily from a straight course). Locating equipment at other locations is at the responsibility of the RV owner. Our product information includes the weight of each individual product.

We specialise in solar power for RVs and understand the importance of reliability during movement particularly on dirt roads and in high humidity environments. That is why we have selected Votronic solar charge controllers and inverters for our system. This German company designs and sells products only for the mobile market, including emergency service vehicles. Their reputation and profitability depends on the on-going quality of the products they sell.

The flexible panels we use have Sunpower E20 cells which have an extremely high efficiency and are long lasting. We supply Lithium Iron Phosphate (LiFePO4) batteries as they are a lighter weight and the best option for RVs.

Our Products page describes our products in more detail.

The solar charge controller (also called 'regulator') displays how much power your panels are generating throughout the day. A battery monitor provides information on the charge state of the battery and the amount of power being used, whilst the inverter provides information on the amount of 240V power consumed.

Some insurance companies allow small systems to be covered under the existing insurance policy. Your insurance company is best able to answer your questions. It is important that the products, the system design, the installation workmanship complies with all applicable regulations and standards. This is detailed in our installation instructions.

You could remove your solar power system and re-install it into your new RV or alternatively, you could include it in the selling price of your RV. Since solar technology is constantly improving it may be beneficial to upgrade to a new solar system in your new RV and leave the current solar system as an attractive selling feature.

We ensure that our products are compliant with applicable Australian and international standards. Our products are of high quality and carefully selected to be suitable for RVs. As well as selling individual components we also offer full kits with everything you need to install a solar power system. Our aim is to make the purchase and installation of your new solar power system as easy and understandable as possible.

We can assist you to choose the right integrated system that meets your power consumption needs.

Solar Panel Questions:

A solar panel is a connected assembly of solar cells capable of producing a voltage when exposed to radiant energy (sunlight).

Photovoltaic (PV) panels are often referred to as just solar panels. Photovoltaic is a combination of the prefix 'photo', which means light, and the word 'voltaic', which means to produce a voltage or electric current. An installation of multiple PV panels is known as a PV array.

Sunlight on photovoltaic panel produces direct current (DC) electricity which in an RV is used to charge a battery.

We can assist you to choose the right integrated system that meets your power consumption needs.

Photovoltaic cells are made of silicon which is a semiconductor material. Silicon is the same thing that makes up sand. It makes up 25.7% of the earth's crust by weight, and is the second most abundant element, exceeded only by oxygen (www.webelements.com).

Even though you can find silicon almost everywhere, making a solar panel is difficult and expensive. The silicon has to be heated to super high temperatures and then formed into very thin wafers. Added to the silicon are phosphorous and boron which creates conductivity within the cell. This activates the movement of electrons across the wires that are built into the solar panel to an electrical circuit connected to the solar panel.

There are three types of solar panel technologies: monocrystalline, polycrystalline and thin film amorphous.

We use Monocrystalline photovoltaic (PV) solar panels which are typically used in high reliability applications. They are more expensive to manufacture but have the best conversion efficiency (the conversion ratio is typically between 16 and 22% which means one square metre of panels exposed to full sun of 1000 Watt per square metre will generate 160W to 220W of electricity) which means they can get more out of each square meter of light than any other type of solar panel. Therefore they are able to generate a significant amount of energy in a small amount of space. While it may not seem much, it is significant when compared to the average 13% conversion of polycrystalline panels, and 6.3% of amorphous thin-film solar panels.

Monocrystalline have a good power-to-size ratio, and an excellent lifespan. They experience a reduction in output at increasing temperatures although the effect is not as large as for polycrystalline panels. A reduction of between 12% and 15% can be expected on a very hot day.

Panels made from polycrystalline cells are the cheapest. Under standard conditions (25oC) their conversion efficiency of sunlight to electricity is 12% to 14% which means that one square metre of panels exposed to full sun of 1000 Watt per square metre will generate 120W to 140W of electricity. A reduction of between 14% to 23% can be expected on a very hot day.

Amorphous Thin Film technology has optimal efficiency in hot weather and is less effective in cooler conditions. They perform well in partial shade but have a shorter lifespan and their conversion efficiency of sunlight to electricity is much less than polycrystalline or monocrystalline panels. Amorphous panels will require about twice as much space as other types of panels which limits their application on RVs because of the limited roof space. They are typically used in portable roll-up camping panels however they have a limited number of watts for the surface area (often 30 W and 60 W is offered). We have recently sourced monocrystalline portable fold-up panels which can be up to 120W.

This depends on how much sun shines onto your panels (Solar Irradiance) over time and how much electricity you use in your RV. The amount of battery storage you have will dictate how much energy you can store.

Solar Irradiance is the amount of solar energy that arrives at a specific area at a specific time. Solar irradiance varies depending on:

  • Time of day (elevation angle varies)
  • Season (elevation angle and strength varies)
  • Cloud cover, pollution (strength varies)
  • Shadowing

Solar insolation is a measure of solar irradiance on a given area over of period of time - typically over the period of a single day. Australian Government weather and climate agencies have this data across the Australian continent, and thus we can compare the average daily amount of solar energy that will "hit" the solar panels on our RV when it is in any part of Australia across an average year. Using this data we can predict how many solar panels you will need for Hobart in winter, or Darwin in summer, to meet your power needs.

The size of your solar system is defined in Watts (W) which indicates how big your solar system is (like a car engine size) not how much it will produce (speed). If you install a higher power system it will produce more electrical energy (a bigger car engine is more powerful). However, the amount of energy your solar cells produce is dependent on the amount, and intensity, of sun it receives (like fuel in a car). A car will go faster when you give it more fuel by pressing the accelerator. A solar panel will charge batteries faster if it receives direct sunlight for a long period. That is why we talk about Solar Irradiance.

The size of your solar system will usually be proportional to the amount of power you will use in your RV. We have designed a Solar Power Estimate Calculator (SPEC) that lets you work out how much electricity you would regularly use and what your ultimate power needs are.

Space and weight limitations and financial budget constraints may also limit or dictate the size of the solar system you choose.

SunPower discovered the phenomena and have fixed the polarisation problem in their current generation cells as described on page 44 in the report on their website: “SunPower has sought to reduce polarization to near zero effect in its current generation of modules, which is so resistant to polarization that it can have any sort of grounding (positive, negative, or ungrounded).” The PV panels we use have SunPower cells.

Our monocrystalline PV solar panels do not have aluminium frames, heavy glass coverings or extensive mounting brackets. Our largest panel which is 135 watts is 3mm thick and weighs 2kg each. They are installed using polyurethane adhesive-sealant (Sikaflex®) rather than mounting brackets.

Our largest panel (135W) weighs 2kg. Two panels will likely meet the needs of most caravaners which will add less than 5kg to the roof, including cables and adhesive sealant.

The high efficiency monocrystalline solar panel that Solar 4 RVs uses are:

  • Light weight with no glass
  • Bendable and conform to the shape of your RV roof – a bending angle of up to 30 degrees
  • Laminated and waterproof
  • Secured with polyurethane sealant adhesive with a screw in each corner for an airtight and minimal-invasive method of attachment
  • Durable and can even be stepped on with soft soled shoes

If installed correctly there will be no damage to the roof and therefore should not compromise your warranty. Check with your RV manufacturer to get confirmation about your warranty.

Our largest Panel is 135W and 1.435m x 0.54m in area. The other sizes are outlined on our products page. There are smaller sizes available if you have specific space limitations.

Polyurethane or Modified Silyl Polymer (abbreviated as MS Polymer or MSP) adhesive sealant is used. This is provided by Solar 4 RVs when you purchase a kit along with all the other components you need to get your solar system installed and working.

If a roof-mounted system proves impractical, then portable panels can be used.

The manufacturer provides a 5 year workmanship warranty and a 10 year warranty that the power output is at least 90% of the rated output at Standard Test Conditions (STC).

Shade does reduce a panel’s efficiency but on a cloudy day there is usually still sufficient light providing energy to the panels. Under a light overcast sky, panels might produce about half as much as under full sun. Ideally the panels should receive no shading between the hours of 8am – 4pm. A bright sunny day that is cool or mild produces the greatest efficiency. On a really hot day the solar panels lose some efficiency but summer is still the best time of year because of the stronger sunlight and longer daylight hours.

When the sun doesn’t shine on your solar panel (at night), it produces no power. The electricity that has flowed into your batteries while the sun was shining is stored so you can use that electricity at night.

Battery Questions:

Solar panels only produce electricity when the sun is shining. On cloudy days the output is less and at night there is none. Batteries store the power generated by the solar panels so you can use your appliances even when the solar panels are not producing electricity. Appliances are therefore being powered by the batteries not the solar panels. Batteries can be recharged by either the solar panels or mains power.

We use Lithium Iron Phosphate (LiFePO4) batteries which have considerable advantages over traditional lead acid, AGM and gel batteries in terms of weight, size, safety, life-span and overall life-span cost.

LiFePO4 batteries have more than twice the useable storage capacity of the same size lead acid or gel battery. Comparative weight example:
12v 100 Ah Gel battery = 30kg
12v 100 Ah LiFePO4 battery = 15kg

The disadvantage of lead acid and gel batteries is that the more amperage you draw, the lower the useable battery capacity. LiFePO4 batteries are more efficient as the effective Amp hours (Ah) available does not drop with the more Amps you draw. See the next question “How is battery capacity calculated?” for an explanation of Ah.

An Amp-hour (Ah) describes a battery's capacity, or in other words, how long it will run before it is flat/drained/empty. The Amp-hour rating for a given battery is the maximum amperage that can be drawn continuously until the battery is completely discharged, flat, empty, drained, dead, over a specific time period.

Battery Capacity (Amp-hour) ÷ Solar Controller Output (Amps) = Charging Time (hours). Your battery will therefore take longer to charge with a smaller solar panel. Charging time will depend on the strength of sunlight, capacity of the battery and how much energy still remains in the battery.

Yes the batteries can be charged by mains power, generator or from your vehicle. Solar 4 RVs solar and mains chargers can be paralleled with other charging methods at the battery, so that you do not have to manually switch between chargers.

Over discharging a battery, for example by inadvertently leaving a light on, can result in permanent damage or failure of your battery.

To prevent this possibility, a low voltage load cut-off switch should be installed. This is a simple voltage sensing relay and is suitable for lead-acid batteries, including gel and AGM.

The new lithium-ion batteries have a very stable voltage during discharge so it is generally not possible to determine the remaining battery capacity based on voltage alone. If a smart battery computer is installed, this can activate a load cut-off relay switch at a set remaining level of charge defined by the user (instead of low voltage). This type of load cut-off is also suitable for all types of lead-acid batteries including gel and AGM.

The number of batteries you require depends on how many electrical appliances you intend to use. Appliances draw electricity directly from the batteries, which are constantly being recharged by the solar panels through the solar charge controller. The number of solar panels you have, and how much sunlight they regularly receive determines how quickly your batteries are recharged.

We have designed a Solar Power Estimate Calculator (SPEC) that lets you work out how much electricity you will regularly use and what your ultimate power needs are. We then recommend a kit of the appropriate number and size of solar panels, batteries and other components. See our 'Assess your needs' page on the website.

Other Product Questions:

The solar charge controller charges the battery. In other words it lets you store the energy being produced by the solar panels in the batteries so you can use the power when you need it. It also regulates the voltage and current from the solar panels and adjusts it to suit the batteries.

Each solar cell has a point at which the current (I) and voltage (V) output from the cell result in the maximum power output of the cell. A PV panel has a maximum efficiency at only one point in the V vs I load curve. An MPPT solar controller automatically and constantly tracks the maximum power point of the PV Panel and ensures that you get the most power possible from your solar panels at any point in time.

It is particularly effective during low light level conditions. During low light level situations it will compensate for the low light level and find the new point at which the solar cell delivers its maximum power output. Note that the MPPT of the panel moves with solar intensity, temperature and aging of the panel.

The battery computer display shows the remaining level of charge of the battery like a “fuel gauge for the battery”.

The battery computer constantly measures the battery voltage together with the current into and out of the battery. It must also have knowledge of the battery capacity - it "learns" this after installation when the user puts the battery through a full charge and discharge cycle. Thereafter, by monitoring of the charging and discharging current, together with programmed characteristics of the battery type, the precise level of charge of the battery will be constantly calculated and shown on the display in remaining charge (%) or in remaining Amp-hours (Ah). It also shows the battery voltage and charging or discharging current.

An inverter converts 12V DC from your battery into 240V AC. If you only need 12V power then you do not need an inverter. Portable inverters provide 240V at the inverter itself, while the output of suitable inverters can be permanently wired by a licensed electrician into the 240V circuit of your caravan / RV.

Australian Standard AS-4763, "Safety of portable inverters" defines three types of portable inverter, of which two types may be permanently installed and connected to the electrical circuits in you caravan or RV.

A portable inverter complying with Australian Standard AS-4763, "Safety of portable inverters" with a socket outlet can be used in a caravan. In this case the user simply plugs an appliance directly into the socket outlet of the inverter. No installation takes place in this case, so an electrician is not required.

In regard to the permanent connection of inverters into a caravan / RV, Australian Standard AS-3001, "Electrical installations-Transportable structures and vehicles including their site supplies", requires that inverters placed into RVs and caravans must comply with Australian Standard AS-4763, "Safety of portable inverters" and be of the isolated or RCD protected type. AS-3001 makes no provision for the installation of any other type of inverter.

Where the AS-4763 compliant inverter is of the isolated type, AS-3001 permits the inverter to have a socket outlet into which the electrician makes the connection to the caravan mains circuit.

Where the AS-4763 compliant inverter is of the RCD protected type, AS-3001 requires that the inverter is permanently connected, i.e not via a socket outlet.

The permanent connection of an inverter into a fixed electrical circuit in a caravan must be carried out by an electrician in accordance with AS-3001. The caravan mains circuits shall include circuit breakers and RCDs and be wired in accordance with AS-3001.

The information provided here is a summary written in layman terms. Australian Standards and State Laws must always be complied with.

Non-true sine wave (often called modified sine wave) inverters are generally smaller, lower cost, lower power devices and are suitable for most equipment. However, even if equipment can tolerate the modified wave-shape it will often will not operate as efficiently with excess heat being produced; AC motors particularly may overheat. Non-suitable devices may not work properly or be permanently damaged.

Pure sine wave inverters produce a similar quality wave shape as provided from the grid into your home, and thus guarantees that all equipment will work just the same as in your home.

Only pure sinewave inverters compliant with AS-3001 and AS-4763 should be permanently connected into the fixed mains circuits in an RV. This agrees with AS-4509 Stand-alone power systems Part 2: System design, which requires that inverter selection considers the harmonic content of the waveform. Modified sine wave inverters have a high harmonic content dependent on their design, whereas true sine wave inverters have a total harmonic distortion (THD) of generally better 3%. A user would reasonably expect that when an appliance is plugged into a socket outlet in the caravan it will work properly and not be damaged. Therefore, using a pure sinewave inverter eliminates the possibility of (expensive) damage to an appliance or device when plugged in by current owners, guests, future owners, or service people.

Note: grid-feed inverters (not used in RVs) have a separate specific requirement for the quality of the waveform (harmonic content).

Several different types of cable are used, each for a different purpose.

Solar Cable: The cable from the PV Panels to the solar controller is the same standard as that required by Australian Standard AS-5033 for use in residential installations, namely PV1-F which is tested and approved to TUV standard 2 Pfg 1169/08.2007.

12V Cable: Automotive grade cable to AS-3191 with insulation to V90 or V90HT grade. The appropriate size cable is provided to minimise cable voltage losses, but at the same time avoid adding unnecessary weight.

Mains Cable: Solar 4 RVs is not currently supplying mains cables so these must be supplied by the installing electrician. Mains cables in transportable vehicles must comply with AS-3001 which requires that conductor cross-sectional area is not less than 1 mm2 and not less than seven strands consisting of either - (a) multi-strand insulated and sheathed cables; or (b) flexible cords. In practice, flexible cord is preferable as this is best able to handle the stresses induced into the cable due to vibration and movement. The flexible cable often installed into caravans and supplied by CMS Electracom (www.cmselectra.com.au) is a 2.5mm 3-core thermoplastic PVC, V-90 sheathed cable to AS-3191, Electric Flexible Cords. Equivalent grade Nexans Olex cable has product ID EAHR05AA003. From the Nexans Olex catalogue 2013, 2.5mm 3-core cable has a rating of 20A when “partially surrounded by thermal insulation”. This is well above the 15A required.

The information provided here is a summary written in layman terms. Australian Standards and State Laws must always be complied with.

Installation Questions:

Installation is generally straightforward, although knowing where to locate the equipment can sometimes be a challenge due to space limitations. As we provide the necessary cable for the installation, the location of all equipment items and cable runs need to be determined before placing an order for a kit.

Prior to the commencement of installation, to ensure personal safety and the safety of the equipment, the detailed installation instructions must be read through in their entirety.

The ideal location for the batteries is over the axle(s) as this will not change the tow ball weight and provides the best towing dynamics. However there is often little or no space adjacent space over the axle for the solar controller and inverter, noting that the mounting orientation of the solar controller and inverter, together with venting requirements must be observed.

The space behind the fridge is often the best place to run the cables from the roof to the solar controller. The cable distance between the solar controller and the battery should be kept to a maximum 2m; as the cable length increases the efficiency of the battery charging will reduce. The distance between the battery and inverter should also be minimised, less than 1 metre is ideal. Again, increasing distance leads to losses in the cable and thereby reducing the real useable capacity of battery.

Assuming that suitable locations have been established for all items and cable runs, the actual installation is straightforward. Care needs to be observed if equipment is installed behind external grills because washing the RV with a hose could lead to water being sprayed into equipment.

The solar panels are attached to the roof of your RV with polyurethane or MS Polymer adhesive/sealant, plus one screw in each corner. The supplied cables are run via a roof cable gland box so that the cables enter the RV at a convenient location. Until the panels are wired to the solar controller the solar panels should covered to avoid any voltage appearing at the end of the cables.

Installation (i.e. mounting and connecting up sequence) and commissioning (i.e. powering up and testing) inside the RV follows a logical order of installing each item of equipment and connecting the cables, but leaving the fuses removed until the commissioning phase. Installation of equipment connected to mains voltages, cables, isolation and protective devices must be installed and commissioned by a licensed electrician.

The commissioning sequence and intermediate checks are detailed in the sequence is, however a summary of the sequence is:

  1. Connect the solar controller to the battery and check solar controller status
  2. Connect the solar controller to the solar panels – then remove the cover from the panels. And check the solar controller status and the battery monitor.
  3. Connect the battery to the load (power consumers) and check operation.
  4. Connect the inverter to the batteries. Check inverter status, battery status, mains status and operation of the system running various loads.


The installation manual supplied with the kit details everything you need to know for installation.

You do not need an electrician to install a 12V kit. For a 240V kit you will need an electrician if the inverter outlet is connected to fixed wiring in the caravan / RV.

To explain this further: Section 45 of the Electricity Safety Act 1998 states only certified persons and organisations can undertake “Prescribed Electrical Installation Work”. Certified organisations and professionals must themselves comply with the Australian Standards. On the internet, there are many instances of incorrect interpretations of parts of the Australian Standards. State laws may place additional requirements to those in the standards.

What this means is that an electrician is required to install an inverter that is connected into the a mains circuit as this is covered under “Prescribed Electrical Installation Work”. In the context of RVs, “Prescribed Electrical Installation Work” covers equipment, isolation and protective devices connected to mains voltages, other than consumer appliances connected via socket outlets. Note that although the solar panel, 12/24V equipment and cabling need not be installed by a qualified tradesperson, there are still some requirements in the Australian Standards to be observed. For example, The Wiring Rules, AS3000, requires that 12/24V (which is within the range of Extra-Low-Voltage defined in AS3000) and mains voltages (defined as Low Voltage in AS3000) must be separated. The standard defines several methods by which this can be achieved, all of which requires physical insulation barriers. With the automotive cable used for the 12/24V, the only method that is feasible is to run the mains cable in a conduit in all compartments or cable runs where automotive and mains rated cable are present. A misconception on one web-site states that a 50mm separation is all that is required, however this requirement relates to minimising electromagnetic coupling between mains cabling and communication cabling.

In accordance with AS3000, the electrician is required to conduct insulation resistance tests between the mains and 12/24V system to verify isolation between the two systems. Hence if the RV owner installs the 12/24V equipment and cabling, this must be done prior to the electrician installing the inverter and mains cabling and protective devices.

The information provided here is a summary written in layman terms. Australian Standards and State Laws must always be complied with.

No permits are required within Australia.

Maintenance Questions:

Solar PV panels have no moving parts and require no maintenance other than the occasional cleaning as needed. A build-up of dust, sap from trees and bat or bird droppings will decrease power output so if the panels require a clean this can be done with a low pressure spray from a garden hose and brush/broom or sponge. High pressure jet should be held sufficiently far away so that the pressure on the surface is no more than the low pressure spray from a garden hose.

The inverter and solar controller should be checked periodically to ensure that venting is kept clear.

The batteries do not require maintenance.

Under the Australian Consumer Law (ACL) a consumer has specific rights in regard to the purchases and services they acquire. These are automatically granted and do not have to be purchased. The ACL guarantees that all goods:
