Introducing the Solis S6-EH3P(29.9-60)K-H((21A) Series – a high-voltage, three-phase energy storage inverter designed for commercial applications and compatible with 3Φ 380V/400V grids. This inverter series delivers a maximum charge and discharge current of 84A + 84A (60K) across two independently controlled battery ports. It also features four integrated MPPTs with a string current capacity of up to 21A, ensuring superior power performance. Whether for on-grid or off-grid use, the S6-EH3P(29.9-60)K-H((21A) series supports parallel operation of up to ten units, with a backup port capable of handling 1.6 times overload for short durations. Thanks to its wide battery voltage range, the series is compatible with a broad selection of batteries and supports peak shaving control in both self-use and generator modes - delivering flexible, efficient, and scalable energy storage for commercial installations.
