About This Product

The Sigenergy 25kW SigenStor Three Phase Controller is a three-phase hybrid energy controller designed to manage solar generation, SigenStor battery storage and grid interaction within the Sigenergy SigenStor system. It provides 25kW nominal AC output and supports up to 40kW of connected PV input.

The controller includes four independent MPPT trackers, an integrated energy management system and support for both on-grid and off-grid operation when installed with the required compatible Sigenergy equipment. It is designed for larger residential systems and light commercial applications where higher three-phase power capacity is required.

Who This Product Suits

The Sigenergy 25kW SigenStor Three Phase Controller suits larger three-phase homes, farms, workshops and light commercial sites using the Sigenergy SigenStor platform. Its 25kW output makes it suitable for properties with substantial daytime loads or larger solar and battery systems.

It is also suitable where multiple roof orientations or separate PV arrays need to be managed, as the four MPPT trackers allow different solar strings to operate independently. For battery applications, it is compatible with SigenStor BAT 5.0 and BAT 8.0 modules, with one to six battery modules supported per controller.

Specifications Explained

The Sigenergy 25kW SigenStor Three Phase Controller has a nominal AC output of 25,000W and a maximum apparent output of 27,500VA. Nominal three-phase output voltage is 380/400V, with a nominal output current of 38A and maximum output current of 41.8A.

On the solar side, it accepts up to 40,000W of PV input, with a maximum DC voltage of 1,100V, 180V start-up voltage and an MPPT operating range of 160V to 1,000V. Four MPPT trackers are provided, with one PV string per MPPT, a maximum input current of 16A per MPPT and a maximum short-circuit current of 20A per MPPT.

Maximum conversion efficiency is 98.3%, with European efficiency rated at 98.0%. The controller carries an IP66 ingress protection rating and includes DC reverse-polarity protection, insulation monitoring, residual-current monitoring, AC overcurrent and short-circuit protection, Type II DC and AC surge protection and anti-islanding protection. Communication options include WLAN, Fast Ethernet, RS485 and Sigen CommMod.

Summary

The Sigenergy 25kW SigenStor Three Phase Controller is a high-capacity three-phase controller for larger Sigenergy solar and battery installations. With 25kW nominal output, support for up to 40kW of PV, four MPPT trackers and compatibility with up to six SigenStor battery modules, it provides a practical platform for larger residential and light commercial energy systems.

Its wide PV operating range, integrated protection functions, IP66 enclosure and built-in communications make it suitable for modern three-phase installations where solar generation, battery storage and energy management need to operate as one coordinated system.
