SigenStor EC 20.0 TP

Item number: C00641

Guarantee: 10 years

The SigenStor EC 20.0 TP is a 20 kW member of Sigenergy's three-phase Sigen Energy Controller series, designed for solar power systems and high-voltage (HV) battery energy storage. The device provides EMS-integrated intelligent management for precise control, supports unbalanced three-phase power output, and can provide 150% peak power in island mode to handle sudden high loads. The maximum 4 MPPT configuration (4 MPPT for this model) helps to achieve efficient energy harvesting in multi-string systems.
