Each ARK 2.5L-A1 consists of 50Ah cells which form 51.2V voltage battery module and sixteen serial connection (1P16S).Two to ten ARK 2.5L-A1 can be connected in parallel and extend the capacity and power of energy storage system. The same type of cell and the same software version of the PACK can be used in parallel. Specifically, the ARK battery system powers the loads through PCS at nighttime without solar; when solar becomes available during daytime, solar energy powers the loads as a priority and store residual solar power into the ARK batter system.
