MultiPlus 48/2000/25-32 230V VE.Bus - 48V inverter/charger PowerAssist
MultiPlus 48/2000/25-32 230V VE.Bus is an inverter/charger that combines a true sine wave inverter and an adaptive charger for 48V batteries in one enclosure. It delivers 1600 W continuous power, charges batteries at up to 25 A, and its PowerAssist technology supplements grid or generator power; units can operate in parallel or three-phase.
Main features:
- Battery voltage: 48 V (38-66 V)
- Continuous power: 1600 W / 2000 VA at 25 °C, 3500 W peak
- Charge current: 25 A, adaptive 4-stage algorithm
- Transfer switch: 32 A
- Maximum efficiency: 95%
- Zero-load power: 10 W, only 3 W in Search mode
The MultiPlus, as the name suggests, is a combined inverter and charger in one elegant package. Its many features include a true sine wave inverter, adaptive charging, hybrid PowerAssist technology, plus multiple system integration features.
