Advantages
High safety
SUNSYS HES XXL integrates advanced power conversion and LFP battery technologies to create a winning formula. The B-Cab ( battery storage cabinet) uses liquid-cooled, lithium iron phosphate chemistry, with an integrated fire protection system, and meets the requirements of the latest international fire code.
The complete system is certified to UL 9540 3rd edition, the safety standard for energy storage systems in both Canada and the USA.
Extreme scalability
Large variety of system configurations are available based on two standard cabinets:
* a 1.3 MVA or 1.5 MVA C-Cab converter cabinet
* a 407 kWh B-Cab battery cabinet
While putting up to 4 systems in parallel it is possible to reach 6 MVA / 26 MWh on a single transformer.
