SigenStor EC 8.0 SP

Item number: C00631

Guarantee: 10 years 

The SigenStor EC 8.0 SP is a single-phase hybrid inverter with a nominal output of 8.0 kW from Sigenergy's intelligent energy storage system , which has been specifically designed for high-performance residential solar power systems, battery energy storage, and full-fledged uninterruptible power supply.

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