Victron MultiPlus Compact 12/2000/80-50 120V VE.Bus (UL 458)

The Victron MultiPlus Compact 12/2000/80-50 is a 2000VA true sine wave inverter, an 80A adaptive battery charger and a 50A automatic transfer switch in one slim, wall-mount enclosure. It's the go-to size for vans, trailers, smaller boats and cabins that want Victron's full VE.Bus feature set without the footprint of a 3000VA unit. PowerAssist tops up a weak shore or generator connection with battery power during high-load moments, and on a shore power or grid failure it transfers to inverter power in under 20 milliseconds — fast enough that computers and other electronics keep running without interruption. A separate 4A output keeps a starter battery topped up, and a programmable relay can be set for alarm, low-voltage or generator start. Add a GX device such as the Cerbo GX (or a VE.Bus Smart Dongle for Bluetooth) for monitoring and control from the VictronConnect and VRM apps.

Compact or standard MultiPlus? Both are 12V, 2000VA, 80A charger, 50A transfer. The Compact is tall and thin for mounting flat on a wall or cabinet side and has a higher 4000W peak rating. The standard MultiPlus 12/2000/80-50 120V is a shorter, deeper box (14.3 x 10.2 x 8.6 in) — pick whichever fits your space. Need more power? See the MultiPlus-II 12/3000/120-50.
