The entire ARK XH-A1 high-voltage energy storage system includes a BDC 95045-A1
(High voltage controller) and multiple ARK 2.5H-A1(battery packs, Number of series less
than 10 ).
Each ARK 2.5H-A1 consists of 50Ah cells which form 51.2V voltage battery pack via one
parallel and sixteen serial connections (1P16S). Two to ten ARK 2.5H-A1 can be
connected in serial and extend the capacity and power of energy storage system.
The ARK XH-A1 battery system powers the loads through hybrid inverter (It can be
equipped with single-phase or three-phase, the following is just an example)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 XH-A1 battery system.
