Dyness HV9637S High Voltage Storage Battery 3.55kWh LiFePO4
The Dyness HV9637S is the lithium iron phosphate battery module that makes up the high voltage storage systems of the Dyness Tower series. Each module has a nominal voltage of 96V, a capacity of 37Ah and a nominal energy of 3.55kWh, of which about 3.37kWh usable with a depth of discharge of 95%.
The modules are stacked in series on the base of the tower: from a minimum of 2 modules (Tower T7, 7.10kWh at 192V) up to 6 modules (Tower T21, 21.31kWh at 576V), and up to 12 towers can be connected in parallel. The IP54 protection rating allows both indoor and outdoor installation; communication with the inverter takes place via CAN/RS485 and the system is compatible with the main high voltage hybrid inverters (Goodwe, Solis, Hoymiles and other brands in the Dyness compatibility list). The declared service life exceeds 6,000 cycles.
