The Victron MultiPlus-II 48/5000/70-50 GX is a 5000VA inverter charger built for 48V battery systems running at 230V AC. It combines an inverter, a battery charger and an integrated GX device in one enclosure, so a separate Cerbo GX or Color Control is not needed for monitoring or configuration.

Key features

• Inverter output, 5000VA / 4000W continuous at 230V AC.
• Battery charger, 70A charge current for 48V battery banks.
• AC transfer switch, 50A, for connecting a grid or generator input alongside the inverter output.
• PowerAssist, draws on the battery to supplement a current-limited grid or generator supply during peak loads.
• Integrated GX device, connects to the VRM portal for remote monitoring, with VE.Bus for communication with other Victron equipment.
• ESS support, configurable for self-consumption, time-of-use optimisation or grid-tied battery backup.

Applications

Suited to off-grid installations with 48V battery banks, grid-tied ESS setups, and generator-backed systems where PowerAssist extends what a small generator can supply. It also fits marine and vehicle installs needing 230V AC from a 48V DC supply. The unit is single phase but can be paralleled or arranged into a three-phase system for larger commercial installations.

Battery compatibility

Configurable charge algorithms support a range of 48V battery chemistries, including lithium (LiFePO4) and lead-acid types.
