Victron MultiPlus 500Va Inverter/Charger

Compact inverter/charger — 500Va inverter + 20A battery charger in one unit

Delivers seamless 240V AC off-grid power and battery charging in a single three-in-one unit. Combining a 500VA pure sine wave inverter, a 20A mains charger and an automatic transfer switch eliminates separate units, cutting installation wiring complexity whilst saving valuable interior space.

The transfer switch allows you to use the same sockets in the van whether you're on grid or off-grid. This is the ideal entry-level choice if your off-grid 240V needs focus on laptops, cameras, and phone chargers alongside steady campsite battery maintenance.

  • 500Va inverter (430W continuous) + 20A battery charger in one unit
  • PowerAssist — supplements shore power with battery power for peaks
  • Pure sine wave — safe for all electronics
  • Seamless transfer between shore power and inverter (<20ms)
  • Compact — smallest in the MultiPlus range
  • G-ST18i AC connector
  • VE.Bus port for Cerbo GX integration
  • Pre-programmed for lithium batteries and fine-tuned for campervan systems before dispatch — less setup, just connect and go

⚡ Key Features

01Three-in-One

Inverter AND battery charger. Eliminates the need for a separate mains charger. Charges at 20A when connected to shore power.

02PowerAssist

If shore power is limited (e.g., 6A hookup), the MultiPlus supplements with battery power to handle peak loads. No more tripped breakers.

03Seamless Transfer

Millisecond switchover between shore power and inverter means your appliances stay running. No interruption when arriving or departing.

04System Integration

VE.Bus port connects to Cerbo GX for full system monitoring via VRM portal. Coordinate with solar and alternator charging for optimal battery management.
