SigenStor EC 4.6 SP

Item number: C00628

Guarantee: 10 years

The SigenStor EC 4.6 SP is a single-phase hybrid inverter with a nominal output of 4.6 kW from Sigenergy's intelligent energy storage system , which is the ideal choice for residential solar systems, battery energy storage, and full-fledged uninterruptible power supply.

The device has a built-in EMS (Energy Management System) that optimizes energy flow between solar panels, batteries, consumers, and the electrical grid in real time. The system is capable of 150% peak power in island mode and provides 0 ms switchover time to backup mode using Sigen Gateway.
