DESCRIPTION

Victron MultiPlus 48/20k/250-100 230V: Professional Off-Grid Energy Management

High-Performance Inverter and Charger for Demanding Applications

The Victron MultiPlus 48/20k/250-100 230V is a premium multifunctional inverter and charger engineered for demanding off-grid, marine, mobile, and industrial setups. Designed to provide a reliable and uninterrupted AC power supply, this unit integrates flawlessly with solar arrays, generators, and grid connections. By combining advanced power conversion technology with intelligent energy management, it ensures your critical systems remain operational even in the most challenging conditions.

Unlike standard power solutions that may struggle with sudden surges, this system delivers an impressive 25 kW of peak power. This high peak capacity is crucial for starting heavy-duty equipment with high inrush currents, such as air conditioners, water pumps, and power tools, without overloading the system. Additionally, the integrated battery charger provides a 250 A charge current, allowing for rapid replenishment of your battery bank. This fast-charging capability is highly beneficial when relying on a generator, as it drastically reduces run hours, minimises noise, and lowers fuel consumption.

Intelligent PowerControl and PowerAssist

Managing multiple power sources can be complex, but the built-in PowerControl and PowerAssist features simplify the process while protecting your equipment. PowerControl allows you to configure a maximum limit for your generator or grid input. The system will prioritise supporting your AC loads and only use the surplus energy for battery charging, preventing the external AC source from overloading.

PowerAssist takes this functionality further by actively supplementing a limited generator or shore power connection with energy from your batteries. When peak demand exceeds the capacity of your AC source, the inverter instantly provides the difference. Once the load decreases, the surplus power is immediately redirected back to charging the batteries. This seamless load sharing provides unmatched stability for high-draw applications.

Seamless Transfer and Dual AC Outputs

In the event of a grid failure or generator disconnection, the main AC output features an ultra-fast transfer switch that takes over in under 20 milliseconds. This acts as an uninterruptible power supply (UPS), ensuring sensitive electronics like computers, servers, and communication gear remain online without rebooting. A secondary AC output is also available, which remains active only when an external AC source is present, making it perfect for high-draw, non-critical loads like water heaters.

Scalable and Future-Proof System Design

For systems that require even more power, up to six units can operate in parallel to achieve higher output. Furthermore, they can be configured for three-phase operation, making this an incredibly versatile foundation for large-scale energy storage systems. When paired with a GX device, you gain full access to the Victron Remote Management (VRM) portal, allowing you to monitor, control, and optimise your entire power system from anywhere in the world.

Delivering an exceptional 20kW of continuous output power and supporting a 38V to 60V DC input range, this specific model is perfectly suited for large commercial battery banks and heavy industrial loads.

Key Features and Benefits

  • High Peak Power: Effortlessly handles high-inrush appliances like motors and compressors.
  • Rapid Battery Charging: High-capacity charger reduces generator run times and maximises solar utilisation.
  • Advanced Load Management: PowerAssist prevents generator overloads by supplementing power from the battery.
  • Uninterruptible Power Supply (UPS): Instantaneous transfer switch keeps critical loads running seamlessly.
  • Scalable Architecture: Supports parallel and three-phase configurations for expanded system capacity.
  • Robust Construction: Housed in a durable aluminium enclosure with fan-assisted cooling for reliable operation in extreme temperatures.

WARRANTY

Victron Energy Limited Warranty Policy

Direct Customers

Victron Energy provides the following warranty to any direct customer (OEM, distributor or dealer) in relation to any products that Victron Energy has directly sold to the direct customer. This warranty is not an end-user warranty between Victron Energy and an end-user, and end-users shall not have any rights or remedies under this limited warranty towards Victron Energy directly. The direct customer shall, in turn, ensure that the end-user is provided with a warranty identical to this warranty, subject to applicable local mandatory law.

End-Users

Victron Energy may also provide a warranty directly to end-users, in which case the below warranty conditions equally apply to such warranty. In that case, end-users shall claim their warranty at their place of purchase or through the original direct customer of Victron, which can be found through the support section on Victron’s website https://www.victronenergy.com/support. Hence, the direct customer shall on behalf of Victron Energy deal with any warranty claims made under any warranty that Victron Energy may provide directly to end-users. This support section on Victron’s website https://www.victronenergy.com/support will provide further guidance on the procedure for end-users to make a claim under this limited warranty.

If the end-user is a consumer – a natural person who is acting for purposes which are outside that person's trade, business, craft or profession – the following applies. The rights and remedies granted to the consumer under this limited warranty are without prejudice to the consumer’s statutory rights. Furthermore, the consumer is entitled by law to remedies from the seller free of charge in the event of a lack of conformity of the goods (such as repair, replacement, price reduction or rescission), which remedies are not affected by this limited warranty.

Warranty

Victron Energy warrants its products to be free from defects in workmanship and materials for a period of 5 years from the date of purchase by the original end-user, with a maximum of 66 months from the Victron Energy invoice date.

In addition to this, proof of correct battery usage is required when making a battery warranty claim.

For a 10% surcharge on the current net price for products that came with a 5-year warranty, an additional 5 years of warranty can be purchased by Victron’s direct customers, bringing the total warranty to 10 years. Warranty extensions need to be applied for ultimately one year before the expiration of the original term. Victron may ask proof that the product was still functional at the time of purchase of the extended warranty.

During the warranty period, Victron Energy will, at its discretion, repair, replace or (partly) credit the defective product free of charge. The warranty does not include performing or reimbursing de‐installation, transportation, and re‐installation.

  • Breakage or damage due to lightning.
  • Connection terminals and screws destroyed or other damages, like overheating, due to insufficient tightening.
  • For any electronic breakage except due to lightning (reverse polarity, over‐voltage due to external cause), the state of the internal control diode and/or the input/output X and Y capacitors determine the warranty.

This warranty will not apply where the product has been misused, neglected, improperly installed, or repaired by anyone other than Victron Energy or one of its authorized Repair Centres. In order to qualify for the warranty, the product must not be disassembled or modified.

This warranty and our warranty obligations thereunder (repair, replacement or credit) are the direct customer’s and, if applicable, the end-user’s sole rights and remedies and our sole obligations with respect to any defective and/or non-conforming product or breach of warranty and is subject to and without prejudice to the limitations of liability in this warranty.

Victron Energy shall not be liable for damages, whether direct, incidental, special, or consequential, even caused by negligence or fault.

As a product requires service, it must be brought back to the place of purchase. In case no contact can be made with the merchant, or if he is either unable or not allowed to provide service, direct contact should be made with Victron Energy through the support section on Victron’s website.

In case Victron Energy replaces a product, it will own the replaced product. Victron Energy owns all parts removed from repaired products. Victron Energy uses new or reconditioned parts made by various manufacturers when performing warranty repairs or building replacement products.

If Victron Energy repairs or replaces a part of a product, its warranty term is not extended: the warranty will apply for the remaining term of the original warranty term. For example, if Victron Energy replaces a product with a 5-year warranty after 3 years, the warranty of this product will apply for another 2 years, with a minimum of 6 months.

All remedies and the measure for damages are limited to the above. Victron Energy shall in no event be liable for consequential, incidental, contingent or special damages, even if having been advised of the probability of such damages.

The foregoing limited warranty provided by Victron Energy is in lieu of any other warranties, express or implied arising by law, course of dealing, course of performance, usage of trade or otherwise, of any kind whatsoever including, without limitation, warranties of merchantability or fitness for a particular purpose, with respect to any product. The above is without prejudice to the arrangement for consumers detailed above.
