Description
The Victron MultiPlus-II 48/5000/70-50 is the workhorse 5kVA inverter/charger for 48V battery systems: a pure sine wave inverter, a 70A adaptive battery charger and a 50A automatic transfer switch in one unit. It's the most popular choice for home backup, off-grid and ESS installations built around a 48V lithium bank.
Key features
- Uninterrupted power (UPS): takes over in under 20 milliseconds if the grid or generator drops out.
- PowerControl and PowerAssist: set your grid or generator limit and the MultiPlus-II reduces charging to avoid overload, then supplements the supply from the battery during peak demand.
- ESS ready: the core component of a Victron Energy Storage System, including Dynamic ESS, with external current sensing to optimise self-consumption.
- Two AC outputs: the second output only runs when AC input is present, keeping non-essential loads off the battery.
- Adaptive charging: suits lithium, AGM and gel batteries.
- Scalable: parallel and three-phase configurations supported.
- Monitoring: pair with a GX device such as the Cerbo GX for local and remote monitoring via the free VRM portal and app.
