7 Products You May Need With Your Solar Panels

When buying solar panels use this checklist to ensure that you have all the components you need for installation and effective operation of your system.

 

1.   Solar Charge Controller and optional battery temperature sensor

A solar charge controller regulates the DC current from the solar panels to the batteries.  Read our buyer guide to assist in choosing which solar change controller meets your requirements.

 

A Battery Temperature Sensor can be used for automatic adaptation and correction of the charging voltage to the battery.

 

2.   LCD/Bluetooth information display

A solar charge controller remote LCD display or app can display the solar charging current, the battery voltage, the power being generated plus the Amp-hrs and the Watt-hrs.

 

3.   Attachment method

Adhesive sealant, high bond tape, vented gap kit, eyelets, zips, bi-adhesive backing

 

4.   Cable, connectors and conduit 

MC4 connectors come pre-attached to most solar panels, a pair of MC4 connectors will need to be added to the cable.

PV1-F is tinned copper, highly stranded, double insulated cable designed for solar installations. 

Standard split tube conduit can be used for low voltage solar installations.

Bootlace pins are recommended to prevent stray strands from arcing.

5.   Cable entry cover

Watertight covers with glands for the cables provide watertight entry into caravan roofs and boat decks.

 

6.   Solar panel short circuit protection

When more than two panels are connected in parallel, MC4 fuses should be installed on each panel to prevent exceeding the maximum current rating of the panel.  A suitable circuit breaker or isolating switch can be used between the panels and solar charge controller.

 

7.   Solar charge controller short circuit protection

A circuit breaker or fuse must be installed between the solar charge controller and the battery and it should be installed as close as possible to the battery.
