The MultiPlus-II will prevent overload of a limited AC source, such as a generator or shore power connection. First, battery charging will automatically be reduced when otherwise an overload would occur. The second level will boost the output of a generator or shore side supply with power taken from the battery.
ESS: Energy Storage Systems:
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.
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.
Remote Monitoring and Control:
Monitor and control your Multi and system or systems' locally (LAN) or remotely via the internet from anywhere in the world, using the free VRM app and free VRM portal website. Access can be from a phone, tablet, laptop or PC for multiple operating systems.
A MultiPlus, plus ESS (Energy Storage System) functionality:
The MultiPlus-II is a multifunctional inverter/charger with all the features of the MultiPlus, plus an external currentsensor option which extends the PowerControl and PowerAssist function to 50A resp. 100A.
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).
Solar energy: AC power available even during a grid failure:
The MultiPlus-II can be used in off grid as well as grid connected PV and other alternative energy systems. It is compatible with both solar charger controllers and grid-tie inverters.
Two AC Outputs:
The main output has no break functionality. The MultiPlus-II takes over the supply to the connected loads in the event of a grid failure or when shore/generator power is disconnected.
Virtually unlimited power thanks to parallel and three phase operation:
Up to 6 Multis can operate in parallel to achieve higher power output. Six 48/5000/70 units, for example, will provide 25 kW / 30 kVA output power with 420 Amps charging capacity.
In addition to parallel connection, three units of the same model can be configured for three phase output.
On-site system configuring, monitoring and control:
Settings can be changed in a matter of minutes with VEConfigure software (computer or laptop and MK3-USB interface needed).
Remote configuring and monitoring:
Install a Color Control GX or other GX product to connect to the internet. Operational data can be stored and displayed on Victron's VRM (Victron Remote Management) website, free of charge. When connected to the internet, systems can be accessed remotely, and settings can be changed.
