Victron Energy MultiPlus-II 12/4k/160-32 230V Inverter Charger

Victron MultiPlus-II 12/4000/160-32 Inverter Charger

The Multiplus-II 12/4K is a powerful 12V inverter charger. It is ideal for large campervans, motorhomes, marine and off-grid systems.

This unit combines a 4000VA pure sine wave inverter, 160A adaptive charger and 32A transfer switch in one efficient device.

When using a 12V battery bank, the Multiplus-II 12/4000 produces reliable 230V power for induction hobs and coffee machines.

It also handles microwaves and other high-demand gear. It switches to external AC supply automatically when shore power is available.

For a full off-grid setup, pair it with a lithium leisure battery and solar charging gear.

PowerControl and PowerAssist for Multiplus-II 12/4K

This unit features PowerControl and PowerAssist. These help you manage limited power from campsites or generators.

PowerControl lets you set the maximum current from the AC supply. It reduces charging demand to prevent overloading the circuit.

PowerAssist supplements shore power with battery energy during peak demand. Spare capacity then recharges the batteries.

Automatic Changeover and UPS Function

If shore power is lost, the Multiplus-II switches to inverter mode in under 20ms. This keeps sensitive computers running without interruption.

The unit offers two AC outputs. One remains powered during outages, while the second only works when external AC is present.

Solar Charging and Battery Monitoring

The Multiplus-II 12/4K can lead your Victron system. Connect solar panels via a Victron SmartSolar MPPT charge controller.

For accuracy, add a Victron SmartShunt or BMV-712 Smart Battery Monitor to track your state of charge.

Connect to a Victron Cerbo GX via VE.Bus. Add a GX Touch display for central control of all Victron monitoring products.

Is the Multiplus-II 12/4000 Suitable for a Campervan?

This model suits large campervans and expedition vehicles with substantial battery banks. It is a strong choice for demanding 230V loads.

A 4000VA inverter draws high current from 12V batteries. Cables and fuses must be sized correctly. Professional installation is recommended.
