The Multiplus-II 48/3000/35-32 is a high-end device combination from Victron Energy that combines classic Multiplus components with an external current sensor and integrated anti-islanding function. This extends the PowerControl and PowerAssist functions to 50 A and extends the potential range of use to ESS applications. The inverter module delivers a full 3000 W with a non-linear load and 2400 W with a linear continuous load. The 48 V battery charger is also very well proportioned with 35 A charging power and is supplemented by a 32 A transfer switch, which can be used to switch back and forth between the AC connections at lightning speed.

A maximum mains or generator current can be set on the MultiPlus-II 48/3000/35-32. The MultiPlus-II then takes account of other connected AC consumers and only uses the current that is still "available" to charge the battery. This prevents the generator or mains connection from being overloaded (PowerControl function). The PowerAssist function adds a new dimension to the PowerControl principle. Load peaks often only occur for a limited period of time. In such cases, the MultiPlus-II immediately compensates for insufficient generator, shore power or mains power with energy from the battery. If the load is reduced, i.e. consumers are switched off, the available energy can then be used to charge the batteries again.
Solar power: alternating current even in the event of a grid failure
The device can be used for both non-grid-connected and grid-connected PV systems as well as other alternative energy systems. It can be used with both solar charge controllers and grid-connected inverters.
Maximum flexibility thanks to two AC outputs
The main output ensures uninterrupted operation. In the event of a mains failure or an interruption in the shore/generator power supply, the MultiPlus-II takes over the supply to the connected loads. The switchover takes place so quickly (in less than 20 milliseconds) that uninterrupted operation of computers and other electronic devices is guaranteed. The second output only supplies power if alternating current is available at the input of the MultiPlus-II. Consumers that must not discharge the battery, such as a water heater, can be connected to this output.
Many options for system expansion
The settings can be changed within minutes using the VEConfigure software (a computer or laptop and an MK3 USB interface are required) and several monitoring and control options are available: Color Control GX, Venus GX, Octo GX, CANvu GX, Laptop, Computer, Bluetooth (with the optional VE.Bus Smart Dongle), Battery-Wächter, Digital Multi Control Panel.
Remote configuration and monitoring
Install a Color Control GX or other GX products to connect to the Internet. The operating data can be stored and viewed free of charge on our VRM (Victron Remote Management) website. If systems are connected to the Internet, they can be accessed remotely and settings can be changed.
