The Victron MultiPlus 12/1600/70-16 combines a true sine wave inverter, an adaptive 4-stage battery charger, and a high-speed AC transfer switch in one compact enclosure. It suits a 12V self-build electrical system where you need serious mains power for demanding loads, plus a heavy-duty charger to top the battery bank back up from shore power or a generator.
The full bridge plus toroidal transformer topology has proven its reliability over many years in the field. The inverter is short-circuit proof and protected against overheating, whether from overload or high ambient temperature.
Key features

1600VA (1300W continuous at 25°C) pure sine wave inverter with a 2800W peak rating for high-inrush loads such as power tools, compressors and induction hobs
70A adaptive 4-stage battery charger (Bulk, Absorption, Float, Storage) plus a 1A trickle output for a separate starter battery
PowerControl and PowerAssist: set a maximum shore or generator current and the unit tops up any shortfall from the battery, so a limited AC source is never overloaded
16A high-speed AC transfer switch with UPS-grade changeover in under 20 milliseconds, so connected equipment does not drop out
Search Mode cuts no-load power draw by around 70% by switching the inverter off between load checks every two seconds
Programmable relay, factory set as an alarm relay for overheat, high ripple or low battery pre-alarm conditions
VE.Bus communication port for remote monitoring and configuration via a GX device
Can run in parallel with up to five further units, or be configured for three-phase operation
