Latest MultiPlus-II 48/5000/70-95 120 volt

Victron Energy MultiPlus-II PMP482505110 48/5000/70-95 120V inverter/charger with 5000VA true sine wave output, 70A battery charging, 95A transfer switch, ESS functionality, PowerControl, PowerAssist, and VE.Bus system integration for 48V marine, mobile, off-grid, backup, and energy storage systems.

The Victron MultiPlus-II PMP482505110 is a 48V, 120V inverter/charger that combines the functions of a MultiPlus with ESS energy storage functionality. It integrates a true sine wave inverter, adaptive battery charger, and automatic transfer switch in one unit for professional marine, yachting, vehicle, and land-based off-grid applications.

PowerControl and PowerAssist help manage limited grid, shore, or generator power. The MultiPlus-II can account for other AC loads and use available remaining power for battery charging, helping prevent overload of the AC source. During short periods of peak demand, PowerAssist can supplement the AC source with battery power, then use spare power to recharge the battery once the load decreases.

The MultiPlus-II can be used in off-grid and grid-connected PV systems and is compatible with both solar charge controllers and grid-tie inverters. It also supports parallel, split-phase, and three-phase operation with compatible units, making it suitable for expandable Victron power systems.

• Confirm the battery bank can safely accept up to 70A charging current.
• Confirm whether the 95A transfer switch and 95A maximum AC input current match your AC system design.
• Confirm whether your application requires ESS functionality, grid-parallel operation, or off-grid operation.
• Check whether an external current sensor or power meter is needed for self-consumption optimization or grid-feed control.
• Verify installation requirements for AC wiring, DC wiring, overcurrent protection, grounding, ventilation, and clearances.
• Confirm whether monitoring or configuration accessories such as a GX device, VE.Bus Smart Dongle, MK3-USB interface, or Digital Multi Control Panel are required.
• For parallel, split-phase, or three-phase systems, confirm that all units are the same compatible model and are configured correctly.
