Off-grid Solar power generation system including solar panel array, PV Combiner box, solar charge controller, battery group, Off-grid inverter, etc. In the sunshine, the solar panel array convert solar energy to DC energy and charge to the battery group by the charge controller. And convert the DC to AC for the loading through off grid inverter.
Sandi Series Solar Charge Controller is a smart PV controller designed for off-grid PV power system. It has good running performance with LCD display and convenient operation. And also automatically control solar cell cut or connect ordinarily according to the change of battery voltage. This controller makes a full advantage of solar cell resource and also keep battery safe and reliable.
To meet different power stations’ need, there are 24V、48V、96V、120V、192V、220V、240V、 360V、480V and other normal series voltage level base on different battery voltage of off-grid PV power station system project.
