SigenStor EC 15.0 TP

Item number: C00639

Guarantee: 10 years

The SigenStor EC 15.0 TP is a 15 kW member of Sigenergy's three-phase Sigen Energy Controller series, designed for solar power systems and high-voltage energy storage with SigenStor BAT battery modules. The device supports precise control of energy flow with EMS-integrated intelligent management, manages the PV side with multiple working point trackers, and provides high instantaneous power in backup (island) mode to supply critical consumers.
