Product Details

Three Phase High Voltage Energy Storage Inverter

Introducing the S6-EH3P(29.9-50)K-H Series. High voltage, three-phase energy storage for commercial applications. The inverter series, which boasts a maximum charge/discharge current of 70A+70A across two independently controlled battery ports, has four integrated MPPTs with a string current capacity of up to 20A – ensuring unmatched power delivery. Whether for on or off-grid applications, the S6-EH3P(29.9-50)K-H series supports parallel operation of up to six units, with a backup port capable of supporting 1.6 times overload for short durations. This latest range compatible with an array of batteries, thanks to its wide voltage range, and offers peak shaving control in both "self-use" and "generator" modes.
