The MultiPlus-II 48/5000/70-50 (230V) is a powerful inverter/charger with ESS support and PowerAssist. It provides seamless backup power and smart energy management. Ideal for solar, off-grid, marine, and backup applications.
The Multiplus-II 48/5000/70-50 230V is a multifunctional inverter/charger with all the features of the MultiPlus, plus an external current sensor option which extends the PowerControl and PowerAssist function to 50 A resp. 100 A. The Multiplus-II 48/5000/70-50 230V 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 application. Several system configurations are possible.
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 insufficient generator, shore or grid power with power from the battery. When the load reduces, the spare power is used to recharge the battery.
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 charge controllers and grid -tie inverters.
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. This happens so fast (less than 20 milliseconds) that computers and othe r electronic equipment will continue to operate without disruption.
The second output is live only when AC is available on the input of the Multiplus-II 48/5000/70-50 230V. Loads that should not discharge the
battery, like a water heater for example, can be connected to this output.
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. But that’s not all: up to 6 sets of three units can be parallel connected for a 75 kW / 90 kVA inverter and more than 1200 Amps charging capacity. The Multiplus-II 48/5000/70-50 230V 8k, 10k, and 15k models can only be connected in parallel if an external AC transfer switch is used. Formore information see the Multiplus-II 48/5000/70-50 230V External Transfer Switch application manual .
Settings can be changed in a matter of minutes with VEConfigure software (computer or laptop and MK3 -USB interface needed). Several monitoring and control options are available: Cerbo GX, Ekrano GX, laptop, computer, Bluetooth (with the optional VE.Bus Smart dongle), Battery Monitor, Digital Multi Control Panel.
Install a Cerbo GX or other GX product to connect to the internet. Operational data can be stored and displayed on our VRM (Victron Remote Management) website, free of charge.
When connected to the internet, systems can be accessed remotely, and settings can be changed.
