Victron Energy MultiPlus II 12/3000/120-50 2x120V Inverter/Charger

Versatile power control for solar and off-grid systems

The MultiPlus is the swiss army knife of electrical management, acting as an inverter, charger, UPS, output booster and ESS (energy storage system) manager. When coupled with a Cerbo GX device, it can be remotely monitored or controlled via touchscreen, web or mobile, too.

PowerAssist

The MultiPlus II can prevent the overload of a limited AC source by boosting the output when required, ensuring your appliances and devices don’t malfunction unexpectedly. It can accomplish this by first reducing battery charging levels to prevent an overload, and if further assistance is required it can also boost the output of the AC generator or shore side supply by taking power from you battery system.

Ideal for Energy Storage Systems (ESS)

The MultiPlus II is perfect for use in combination with MPPT solar chargers and other Victron energy devices. In the event of a grid failure, or when shore or generator power is disconnected, the MultiPlus can act as a UPS, providing uninterrupted AC power. It does this by activating its inverter to take over supply to your connected loads. It’s able to do this in less than 20 milliseconds, which is so fast that even complex electronic devices such as computers will operate without disruption.

Remote monitoring and control

The MultiPlus II is compatible with the Cerbo GX and Touch GX monitoring system, providing remote monitoring and control over the web, mobile app or touchscreen.
