It does not apply to Ni-MH, Li-ion or other batteries.Only suitable for regulating solar modules.Connect the battery to the recharge regulator-positive and negative. If a 12 V battery is detected, it will display 1 and if a 24V battery is detected, it will display 2. Connect the photovoltaic module to the regulator-plus and minus, and then to the recharging regulator-plus and minus. The reverse order applies when uninstalling. Improper sequence will damage the controller.Packing list:1 * Solar ControllerPackage List:1 * Solar Controller
