Victron MultiPlus 12/3000/120-50 230V VE.Bus

The Victron MultiPlus 12/3000/120-50 combines a powerful pure sine wave inverter, an intelligent battery charger and a fast automatic transfer switch in one dependable unit. Designed for demanding 12V electrical systems, it is an excellent choice for boats, motorhomes, off-grid installations and backup power applications.

Delivering 3000VA of inverter power and up to 6000W peak output, the MultiPlus can handle demanding appliances and the high start-up loads produced by equipment such as pumps, compressors and power tools. Its pure sine wave output provides clean, stable 230V power suitable for sensitive electronics.

When shore power or generator power is available, the built-in adaptive charger can supply up to 120A to the leisure battery bank. A separate 4A output can also maintain a compatible starter battery. If the external AC supply fails, the MultiPlus automatically switches to inverter power quickly enough to keep most connected electronics operating.

Victron’s PowerControl feature prevents a limited shore connection or generator from being overloaded by reducing the charging current when necessary. PowerAssist goes further by supplementing the incoming AC supply with energy from the battery during periods of high demand.

VE.Bus connectivity allows advanced configuration, remote monitoring and integration with compatible Victron system components. Multiple units can also be configured for parallel or three-phase operation when greater capacity is required. These functions and ratings are detailed in the official Victron MultiPlus manual.
