Victron Multiplus-II 48V 5KVA
The MultiPlus-II is a multifunctional inverter/charger with all the features of the MultiPlus, plus an external current sensor option that extends the PowerControl and PowerAssist function to 50A resp. 100A. The MultiPlus-II is ideally suited for professional marine, yachting, vehicle, and land-based off-grid applications. It also has built-in anti-islanding functionality and an increasingly long list of country approvals for ESS applications. Several system configurations are possible. For more detailed information see the ESS Design and configuration manual.
PowerControl And PowerAssist – Boosting The Capacity Of The Grid Or A Generator
A maximum grid or generator current can be set. The MultiPlus-II will then take account of other AC loads and use whatever is extra for battery charging, thus preventing the generator or grid from being overloaded (PowerControl function).
PowerAssist takes the principle of PowerControl to a further dimension. Where peak power is so often required only for a limited period, the MultiPlus-II will compensate for insufficient generator, shore, or grid power with power from the battery. When the load reduces, the spare power is used to recharge the battery.
UNINTERRUPTED AC POWER (UPS FUNCTION)
In the event of a grid failure, or when shore or generator power is disconnected, the inverter within the Multi is automatically activated and takes over the supply to the connected loads. This happens so fast (less than 20 milliseconds) that computers and other electronic equipment will continue to operate without disruption.
The MultiPlus-II is the key component in a Victron ESS system, providing the flexibility to combine with MPPT Solar Chargers or Grid-tie PV Inverters.
