Sigenergy SigenStor EC 4.6 SP Energy Controller

The Sigenergy SigenStor EC 4.6 SP is a 1-phase hybrid energy controller that combines solar energy, battery storage and the grid connection in one intelligently controlled system. This controller is the heart of the SigenStor home energy system and has been designed for maximum flexibility, safety and yield.

With integrated energy management (EMS), 2 MPPT trackers and a high DC/AC ratio, you get more out of the installed PV capacity. Combined with the SigenStor battery modules and gateway, the EC 4.6 SP offers a fully integrated solution for storage and back-up.

Key features

• 1-phase hybrid energy controller (4.6 kW)
• Integrated EMS (Energy Management System)
• 2 MPPT trackers for maximum PV utilisation
• High DC/AC ratio (max. 2.0)
• Back-up support (0 ms switchover in combination with the gateway)
• IP66 protection class – suitable for indoor and outdoor installation
• Communication via WLAN / Ethernet / RS485 (4G optional)

Application

The SigenStor EC 4.6 SP is used in:

• 1-phase homes with a PV installation
• Installations with battery storage (now or later)
• Systems with a heat pump or EV charging
• Projects where back-up functionality is required
