Victron MultiPlus 48/20k/250-100 230V Inverter Charger | PMC483200400

The Victron MultiPlus 48/20k/250-100 230V is a 20kVA inverter charger built for large off-grid, backup and industrial power installations. It runs from a 48V DC battery bank and produces 230V AC output, combining a pure sine wave inverter with a 250A charger in one enclosure.

Key features of this battery charger with inverter

• Inverter output, 20,000VA (20kVA) at 230V AC from a 48V DC input.
• Charger current, 250A with an adaptive charge algorithm for different battery types.
• PowerControl, limits current draw from a generator or shore power to prevent overload.
• PowerAssist, draws on battery power to cover load spikes beyond what the AC source can supply.
• Waveform, pure sine wave, suitable for motors, compressors and sensitive electronics.
• Transfer switch, switchover in less than 20 milliseconds (typical).

System integration

Up to six units can run in parallel, and three units can be configured for three-phase output, making this unit suitable for commercial or industrial sites with heavier or three-phase loads. Communication runs over VE.Bus, with configuration and monitoring available through VictronConnect or a Venus OS device such as Cerbo GX.

Applications

This inverter charger suits large off-grid agricultural and commercial installations, marine vessels, and critical backup systems where a smaller unit cannot cover the load. The 48V DC architecture keeps DC cable currents manageable at this power level.

Handling and installation

At 63.5kg, the unit needs suitable lifting equipment and a mounting structure rated for its weight. Installation should follow the wiring and protection guidance in the Victron documentation for this model.
