Description
Rack-level management means the state of each rack is tracked separately, and the container as a whole is not treated as a single average value. Cooling is liquid, and in Center L Plus the loop is duplicated, so the failure of one loop does not stop heat removal. The Plus version has electrolyte and coolant leak sensors and fire suppression at battery module level, so a fault is contained before it reaches neighbouring modules. The container is 20-foot, and Center L Plus is supplied fully assembled at the factory, which simplifies commissioning on site. The design meets the requirements of NFPA 855 and UL 9540 and is tested to UL 9540A.
How to choose
The difference between the variants is protection. The base Center L is enough when liquid cooling and rack management are sufficient, and Center L Plus is taken for sites with stricter safety requirements. If you need a capacity of 6.25 MWh with the converter in the block, look at Center L Ultra with a cycle life of 15 000 cycles. For a DC voltage of 1500 V or 1000 V and 20 and 40 ft formats, Center F is suitable.
