The main output has an uninterrupted power supply function. In the event of a grid failure or disconnection of shore or generator power, the MultiPlus takes over supplying the connected loads. This transfer is so fast (less than 20 milliseconds) that the operation of connected computers or other sensitive electronic equipment will not be disturbed. The second output is energized only when AC is available on one of the MultiPlus inputs. Loads which would not discharge the battery, such as a water heater for example, can be connected to this output (second output available on models of 3 kVA and above).
Virtually unlimited power thanks to parallel operation
Up to 6 Multis can run in parallel to get more power output. For example, six 24/5000/120 units will provide 25 kW / 30 kVA output power and 720 A load capacity.
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 3 units can be connected in parallel to provide 75 kW / 90 kVA of power and more than 2000 A of load capacity
The MultiPlus has a very powerful battery charger which requires high currents from shore or generator connections (nearly 10 A at 230 VAC per 5 kVA Multi). The Multi Control control panel makes it possible to limit the power to be supplied by the shore or by the generator. The MultiPlus then takes into account the power demand of other output AC loads and will only use the excess for the load, thus avoiding any overloading of the shore power or generator.
PowerAssist – More power from shore or generator
This function gives an extra dimension to the principle of PowerControl By allowing the MultiPlus to supplement the capacity of the alternative source. If a high peak power demand is required for a short time, the MultiPlus helps ensure that the lack of power from the grid or generator is immediately compensated by energy from the battery. And when demand drops, the excess power will be used to recharge the batteries.
The MultiPlus can be used both off-grid and connected to a PV grid or other alternative energy systems. Mains loss detection software is available
