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.
Inverter AND battery charger. Eliminates the need for a separate mains charger. Charges at 20A when connected to shore power.
If shore power is limited (e.g., 6A hookup), the MultiPlus supplements with battery power to handle peak loads. No more tripped breakers.
Millisecond switchover between shore power and inverter means your appliances stay running. No interruption when arriving or departing.
VE.Bus port connects to Cerbo GX for full system monitoring via VRM portal. Coordinate with solar and alternator charging for optimal battery management.
The MultiPlus 500Va delivers approximately 350W continuous (500Va, 1000W peak). Also charges your battery at 20A when on shore power. Here's what it can run:
10-25W
Multiple devices
45-90W
Any laptop charger
10-50W
30-50W
50-100W
50-100W
Single size, short use
500-800W
Too much — will trip
600-1000W
Too much
1200-2000W
Too much
Phone + Laptop + LED lights + TV: ~200W — comfortable
Laptop + fan + phone: ~150W — fine
Electric blanket + phone charger: ~120W — short periods
Va (volt-amps) differs from watts due to power factor. Brief peaks above rated output are OK, but continuous load should stay within 350W.
