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

The Victron Energy MultiPlus-II 48/5000/70-50 230V GX is a high-capacity inverter/charger with an integrated GX communication and monitoring platform. Built for advanced 48V off-grid, marine, RV, and backup systems, it combines a 5000VA pure sine wave inverter, a 70A adaptive battery charger, and a 50A high-speed transfer switch. When shore or generator power is present, it passes AC through while charging your battery bank. If the AC source fails, it switches to inverter power instantly to keep critical loads running. With PowerControl and PowerAssist, it manages limited AC inputs and supports surge-heavy appliances smoothly. The built-in GX feature adds onboard system monitoring, remote access, and seamless integration with Victron’s ecosystem.

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

5000VA pure sine wave inverter – Delivers clean, stable 230V AC power suitable for sensitive electronics and heavy household loads.

High surge capability – Supports demanding startups with up to 9000W peak output.

70A adaptive battery charger – Multi-stage charging for 48V banks, including lithium when configured.

50A transfer switch – Automatic and fast switching between AC input and inverter output.

Frequently-Asked Questions

What makes the GX version different?

The GX version includes built-in system monitoring and communications, allowing easier remote access, data logging, and integration with Victron monitoring tools without needing a separate GX device.

What size systems is this model best for?

It’s designed for larger 48V systems needing high continuous output (5000VA) and strong surge handling, such as off-grid homes, marine platforms, and large RV builds.

Can it handle high-surge appliances?

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

Does it support lithium battery banks?

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

Can I expand to parallel or three-phase later?

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