Advantages

High safety standards

The SUNSYS HES XXL system has been designed using the best battery technologies, primarily to achieve a high level of safety. The B-Cab (battery storage cabinet) is based on lithium iron phosphate (LFP) chemistry and a point thermal management system ensures safety thanks to liquid cooling and a fire protection system. The latter includes heat and smoke detectors, an aerosol fire extinguishing system, a hose to connect a water inlet and a blowout panel.
The B-Cab is certified UL 9540A guaranteeing that it will withstand thermal runaway.

Maximum flexibility

Based on 3 cabinets and 2 types of battery cabinet (0.5C and 1C), SUNSYS HES XXL offers a wide range of configurations using a 1.5 MVA C-Cab conversion cabinet, an M-Cab control cabinet and a 407 kWh B-Cab battery cabinet in 0.5C or 379 kWh in 1C.
The system can be used in parallel up to 6 MVA / 20 MWh on a single transformer. For larger installations, it is possible to put several systems in parallel.

Combines the best technologies

Thanks to joint-design between CATL and Socomec, you can be assured of compatibility between products, and that the complete system has been validated and certified.
The M-Cab cabinet (Master cabinet) has been designed to control the entire system, including the battery management system (BMS) along with the PLC for automation functions and connection to an external EMS.
The software has been specially developed to enable internal communication between all cabinets in the system.

Integrated ready to use certified system

- Certified and tested systems including; converter, batteries and the control cabinets all together.
- Specifically developed software adapted to enable internal communication between all cabinets.
