MultiPlus-II 12/5000/220-50 230V - 12V inverter/charger with 2 AC outputs
MultiPlus-II 12/5000/220-50 230V is a multifunctional inverter/charger with two AC outputs, suitable for marine, vehicle and off-grid systems as well as ESS installations. PowerControl prevents grid or generator overload, PowerAssist boosts power during peak demand, and during an outage it switches over in milliseconds. It charges 12V batteries at up to 220 A.
Main features:
- Battery voltage: 12 V (9.5-17 V)
- Continuous power: 4000 W / 5000 VA at 25 °C
- Charge current: 220 A, adaptive 4-stage algorithm
- Transfer switch: 50 A
- Maximum efficiency: 95%
- Protection rating: IP22
The MultiPlus-II is a multifunctional inverter/charger with two AC outputs. Suitable for professional marine, yachting, vehicle, and land-based off-grid systems, it also provides the isolation and redundancy required for ESS setups. PowerControl allows the MultiPlus-II to prevent grid or generator overload, while PowerAssist boosts AC power during peak demand. In the event of an outage, the inverter switches over in milliseconds, keeping computers and sensitive electronics running without interruption. The battery charger combines speed with efficiency through a smart adaptive algorithm that extends battery life. Ready for expansion, the MultiPlus-II supports parallel and three-phase configurations when a system needs to scale.
Note: for a short period of time this product was called MultiGrid-II.
