Victron MultiPlus-II 12/3000/120-32 Inverter/Charger

The Victron MultiPlus-II 12/3000/120-32 is a multifunctional inverter/charger for 12 V battery systems, combining a powerful sine wave inverter, a sophisticated battery charger and a high-speed AC transfer switch in a single compact enclosure. It is well suited to professional marine, vehicle and land based off-grid installations, and serves as a core component in a Victron Energy Storage System (ESS) with built-in anti-islanding for grid-connected use. Its PowerControl and PowerAssist functions let it work alongside a limited shore or generator supply, first reducing charge current and then boosting the available power from the battery to prevent the source being overloaded. When the incoming supply fails, the inverter takes over the critical loads within milliseconds, so connected electronics keep running without interruption. An optional external AC current sensor extends current sensing for self-consumption optimisation and grid feed control. A second AC output powers loads that should shut down when no external AC is present, and units can be paralleled or arranged for three-phase operation as systems grow. Configuration is handled through VEConfigure with an MK3-USB interface, while connecting a GX device such as a Cerbo GX adds local and remote monitoring through the free VRM portal.
