Advantages
High safety
SUNSYS HES XXL integrates advanced power conversion and LFP battery technologies to create a winning formula. The B-Cab XXL (Battery Cabinet) uses liquid-cooled thermal management, with an
integrated fire safety system, and meets the requirements of the latest international fire code.
The complete system is certified to the latest UL 9540, the safety standard for energy storage systems in both Canada and the USA.
Extreme scalability
Large variety of system configurations are available based on three standard cabinets:
- C-Cab XXL: Converter Cabinet from 1Â to 1.5 MVA
- B-Cab XXL: Battery Cabinet of 407kWh
- M-Cab XXL: Master Control Cabinet embedding smart components
While putting up to 4 systems in parallel it is possible to reach 6 MVA / 23 MWh.
Fully bankable supplier
Socomec is a 100+ years old company with expert knowledge in power conversion, switching and monitoring.Â
With our energy storage experience of 10+Â years and 420+ systems installed worldwide,
we have proven our knowledge and support process on the field.
Integrated ready-to-use certified system
SUNSYS HES XXL systems, including inverter, batteries and control cabinets, are certified and tested. Our systems have undergone a type-testing procedure to guarantee reliable behavior and performance, reducing the time and effort required for commissioning.
Specially adapted software for internal communication between all cabinets has been developed allowing efficient monitoring and control of the system, called PMS. Going a step further, we enabled thanks to SunSpec standard an easy integration with external EMS if you require it.
Whether you have a switchboard, solar system, generators or other equipment on site, our systems are designed to be compatible with a wide range of existing installations.
