Advantages
High safety standards
SUNSYS HES L integrates advanced power conversion and LFP battery technologies to create a winning formula.
The B-Cab L (Battery Cabinet) uses liquidcooled 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 the Canada and the USA.
Extreme modularity
SUNSYS HES L is a modular energy storage system that uses 2 standard cabinets to enable 29 UL-certified configurations, providing ideal system sizing for a variety of projects.
- C-Cab L: Converter Cabinet from 50 to 300 kVA per Cabinet.
- B-Cab L: Battery Cabinet of 203 kWh.
2 C-Cabs L can be stacked in parallel with up to 6 B-Cabs L reaching a maximum configuration of 550 kVA / 1218 kWh. Standard configurations simplify the design, quotation, installation and commissioning process of your projects.
Fast and safe installation
SUNSYS HES L is supplied with all internal energy modules pre-assembled and plug and play power modules to guarantee maximum quality, the rapid installation and ease of transport. It includes all cables and hardware to connect the B-Cabs and C-Cabs. The battery cabinets are delivered fully assembled, and include made-to measure cable kits for DC, communication and auxiliary power connections.
Combines the best technologies
Thanks to a co-design between CATL and Socomec, you can be assured of compatibility between products, and that the complete system has been validated and certified. The C-Cab (power conversion cabinet) has been designed to include everything required for battery operation, including the management system as well as the power supply.
Fully bankable historical supplier
Socomec is a 100+ years old company with expert knowledge in power conversion, switching and monitoring. With our energy storage experience of 10+ 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 L systems, including inverter, batteries and control components, are fully integrated, tested and certified.
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.
