About This Product

The Sigenergy 15kW SigenStor Three Phase Controller is a 15kW three-phase hybrid energy controller for SigenStor solar and battery systems. It combines solar inverter, battery power conversion and energy management functions within the SigenStor platform, allowing PV generation and compatible SigenStor battery modules to be managed through one controller.

The Australian model is identified as SigenStor EC 15.0 TP AU. It provides 15,000W nominal three-phase AC output and supports direct connection of up to 24,000W of PV input, making it suitable for larger residential and light commercial solar and storage installations.

Who This Product Suits

The Sigenergy 15kW SigenStor Three Phase Controller suits properties with a three-phase electrical supply that require a higher-capacity solar inverter with the option of integrated battery storage.

It is particularly suited to larger homes, properties with substantial daytime loads, three-phase equipment, EV charging or light commercial applications. It can be paired with compatible SigenStor BAT 5.0 or BAT 8.0 battery modules, with one to six battery modules supported per controller.

Specifications Explained

The Sigenergy 15kW SigenStor Three Phase Controller has a nominal AC output power of 15,000W at 380/400V three phase, with a nominal output current of 21.7A. Maximum PV input power is 24,000W.

It uses three independent MPPT trackers, with one PV string per MPPT. Each MPPT supports up to 16A operating current and 20A short-circuit current. The MPPT operating range is 160-1000V, maximum DC input voltage is 1100V and start-up voltage is 180V.

Maximum inverter efficiency is 98.3%, with European efficiency rated at 97.9%. Compatible SigenStor batteries operate over a 600-900V battery voltage range. The controller includes WLAN, Fast Ethernet, RS485 and Sigen communication options and carries an IP66 ingress protection rating.

Integrated protection functions include DC reverse-polarity protection, insulation monitoring, residual-current monitoring, AC overcurrent, overvoltage and short-circuit protection, Type II DC and AC surge protection and anti-islanding protection.

Summary

The Sigenergy 15kW SigenStor Three Phase Controller is a high-capacity three-phase controller for installations combining solar generation with the SigenStor battery platform. Its 15kW AC output, 24kW maximum PV input, three MPPT trackers and support for up to six compatible battery modules make it a practical option for larger residential and light commercial systems where solar, storage and energy management are being integrated into one system.
