The 40-50KW three-phase high voltage energy storage inverter is the advanced solution for medium and small-scale commercial and residential energy applications. This series comes in power capacities of 40kW and 50kW and is able to support multi-machine parallel operations to configure scalable systems. Fitted with an STS switch for switchover without interruption, this inverter can work as a UPS system and support generator integration. Compatible with high-power solar modules up to 210mm and 182mm components, the system allows for a maximum input current of 21A and 1.1x of continuous overload on the grid side. Safety features are enhanced with DC arc protection and dual AC/DC surge protection that guarantee safe operation of your energy system in various environments.
