SigenStor EC 12.0 SP

Item number: C00633

Guarantee: 10 years

The SigenStor EC 12.0 SP is a single-phase hybrid inverter with a nominal output of 12.0 kW for the Sigenergy smart energy storage system. It is designed for high-performance residential and small commercial solar systems with battery energy storage and full uninterruptible power supply.

The device optimizes energy flow between solar panels, batteries, consumers, and the electrical grid with integrated EMS (Energy Management System) control. The system is capable of delivering up to 150% peak power in island mode and provides true 0 ms transfer to backup power using Sigen Gateway.
