Sigenergy SigenStor EC 20.0 TP Energy Controller

The Sigenergy SigenStor EC 20.0 TP is a 3-phase hybrid energy controller that integrates solar energy, battery storage and the grid connection within one intelligently controlled system. This controller is the heart of the SigenStor home energy system and has been developed for homes and installations with higher power demand, a heat pump or EV charging.

With integrated energy management (EMS), 3 MPPT trackers and a high DC/AC ratio, the EC 20.0 TP makes optimal use of the installed PV capacity. Combined with SigenStor battery modules and the Sigen Gateway, this controller offers a fully integrated solution for storage and back-up.

Key features

• 3-phase hybrid energy controller (20 kW)
• Integrated EMS (Energy Management System)
• 3 MPPT trackers (model-dependent)
• Unbalanced 3-phase output for efficient operation
• 150% peak output in off-grid mode
• Back-up support (0 ms switchover in combination with the gateway)
• IP66 protection class
• Communication via WLAN / Ethernet / RS485 (4G optional)

Application

The SigenStor EC 20.0 TP is used in:

• 3-phase homes and commercial buildings with a PV installation
• Installations with a heat pump or heavier electrical loads
• EV charging in combination with battery storage
• Systems where phase balance and high power output are important
• Installations where back-up functionality is required
