Victron Energy MultiPlus-II 48/5000/70-50 230V

The Victron Energy MultiPlus-II 48/5000/70-50 is a robust 48V inverter/charger for demanding off-grid, marine, RV, and backup applications. It combines a 5000VA pure sine wave inverter, a 70A adaptive battery charger, and a high-capacity 50A transfer switch in one unit. When shore or generator power is available, it passes AC through while charging your battery bank. If the AC source fails, it switches to inverter power automatically to keep essential loads running without interruption. PowerControl and PowerAssist help manage limited AC inputs and support short surge demands smoothly.

Victron Energy MultiPlus-II 48/5000/70-50 230V Features

5000VA pure sine wave inverter – Produces clean 230V AC power suitable for sensitive electronics and household appliances.

High surge capability – Handles heavy startup loads with up to 9000W peak output.

70A adaptive battery charger – Efficient multi-stage charging for 48V battery systems, including lithium profiles when configured.

50A transfer switch – Fast automatic switching between AC input and inverter output for seamless operation.

PowerControl – Prevents overloading weak shore or generator sources by limiting input current.

PowerAssist – Supplements limited AC input with battery power during short load spikes.

VE.Bus communication – Enables monitoring, remote control, and system expansion (parallel or three-phase).

Programmable relay – Can be configured for alarms, generator auto-start, or other control events.

Durable steel enclosure – Built to withstand mobile and fixed installations in harsh environments.

Frequently-Asked Questions

What size systems is this model designed for?

This unit is intended for larger 48V systems needing high continuous AC output and strong surge handling, such as off-grid homes, marine systems, and large RV builds.

Can it start high-surge appliances?

Yes. With up to 9000W peak power, it supports startup loads from pumps, compressors, power tools, and similar motor-driven equipment.

Does it work with lithium battery banks?

Yes. The charger supports lithium profiles when configured correctly in Victron settings.

Can I expand later to parallel or three-phase?

Yes. VE.Bus enables parallel stacking and three-phase operation with compatible Victron units.
