Victron Energy MultiPlus-II 48/10000/140-100 inverter

The Victron Energy MultiPlus-II 48/10000/140-100 is a powerful and versatile inverter/charger designed for professional and residential energy systems. Combining a 48V 10000VA inverter with a 140A battery charger and a 100A AC transfer switch, it delivers reliable power conversion, battery charging, and grid interaction in a single unit. Ideal for off-grid, backup, and mobile applications, it features PowerAssist technology, pure sine wave output, and parallel/three-phase capability for scalable system design.

Advantages

High continuous power output (8000W at 25°C) and peak power handling (20000W) ensure reliable operation for demanding loads. The integrated 140A battery charger supports fast charging of lead-acid and lithium batteries. PowerAssist technology prevents overloads by supplementing generator or grid power with battery power. The unit can be paralleled with up to six units for higher power or configured for three-phase output. VE.Bus communication enables seamless integration with other Victron components and remote monitoring.
