About this product

INVERTERS · 800VA · INVERTER + CHARGER
✓ Pure Sine Wave✓ 800Va✓ Built-in 35A Charger✓ PowerAssist
Inverter/charger — 800Va inverter + 35A battery charger, a step up from the 500Va

Delivers seamless 240V AC off-grid power and battery charging in a single three-in-one unit. Combining an 800VA pure sine wave inverter, a 35A 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 choice if you need extra headroom for powering laptops, power tool chargers, or small appliances simultaneously without stepping up to a larger system.

  • 800Va inverter (650W continuous) + 35A battery charger in one unit
  • PowerAssist — supplements shore power with battery for peaks
  • Pure sine wave — safe for all electronics
  • Seamless transfer between shore power and inverter (<20ms)
  • 35A charger — faster battery charging than 500Va
  • 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 35A when connected to shore power.

02PowerAssist

If shore power is limited, 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.

🔌 What Can It Run?

The MultiPlus 800Va delivers approximately 650W continuous (800Va, 1600W peak). Also charges your battery at 35A when on shore power. Here's what it can run:

✓

10-90W
All devices

✓

LED Lighting

10-50W

✓

TV (up to 32-inch)

50-150W

✓

Electric Blanket

50-100W

✓

Travel Kettle (low-wattage)

500-800W
Low-wattage travel kettle only — short bursts

✓

Small Microwave (600W)

600-700W
Short use — check battery capacity

✗

Standard Kettle

2000-3000W
Too much

Too much for continuous use

Combined Load Examples

Phone + Laptop + TV + LED lights: ~300W — comfortable

Low-wattage kettle + phone: ~800W — short bursts only

Small microwave + lights: ~750W — check battery

Va differs from watts due to power factor. Brief peaks above rated output are OK. Continuous load should stay within 650W.
