Multiplus inverter/charger

Multi-functional, with intelligent power management

The MultiPlus is a powerful true sine wave inverter, a sophisticated battery charger that features adaptive

charge technology, and a high-speed AC transfer switch in a single compact enclosure. Next to these

primary functions, the MultiPlus has several advanced features,

Two AC Outputs

The main output has no-break functionality. The MultiPlus takes over the supply to the connected loads

in the event of a grid failure or when shore/generator power is disconnected. This happens so fast (less

than 20 milliseconds) that computers and other electronic equipment will continue to operate without


The second output is live only when AC is available on one of the inputs of the MultiPlus. Loads that

should not discharge the battery, like a water heater for example, can be connected to this output

(second output available on models with 50A transfer switch only).

Virtually unlimited power thanks to parallel operation

Up to 6 Multi's can operate in parallel to achieve higher power output. Six 24/5000/120 units, for example,

will provide 25 kW / 30 kVA output power with 720 Amps charging capacity.

Three phase capability

In addition to parallel connection, three units of the same model can be configured for three-phase

output. But that’s not all: up to 6 sets of three units can be parallel connected for a huge 75 kW / 90 kVA

inverter and more than 2000 Amps chargering capacity.

PowerControl - Dealing with limited generator, shore side or grid power

The MultiPlus is a very powerful battery charger. It will therefore draw a lot of current from the generator

or shore side supply (nearly 10A per 5kVA Multi at 230VAC). With the Multi Control Panel a maximum

generator or shore current can be set. The MultiPlus will then take account of other AC loads and use

whatever is extra for charging, thus preventing the generator or shore supply from being overloaded.

PowerAssist - Boosting the capacity of shore or generator power

This feature takes the principle of PowerControl to a further dimension. It allows the MultiPlus to

supplement the capacity of the alternative source. Where peak power is so often required only for a

limited period, the MultiPlus will make sure that insufficient shore or generator power is immediately

compensated for by power from the battery. When the load reduces, the spare power is used to recharge

the battery.

Four stage adaptive charger and dual bank battery charging

The main output provides a powerful charge to the battery system by means of advanced ‘adaptive

charge’ software. The software fine-tunes the three stage automatic process to suit the condition of the

battery, and adds a forth stage for long periods of float charging.
