Sigenergy SigenStor EC 15.0 TP Energy Controller

The Sigenergy SigenStor EC 15.0 TP is a 3-phase hybrid energy controller that integrates solar energy, battery storage and grid connection within a single intelligently controlled system. This controller is the heart of the SigenStor home energy system and has been developed for homes and installations with a 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 15.0 TP makes optimum 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 alike.

Key features

• 3-phase hybrid energy controller (15 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 gateway)
• IP66 protection class
• Communication via WLAN / Ethernet / RS485 (4G optional)

Application

The SigenStor EC 15.0 TP is used for:

• 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
