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.

1, Digital design, modular structure, stable and reliable.
2, LCD panel (backlighting) show working parameters and the status.
3, High efficiency by PWM charging method.
4, Be able to offer DC power supply (optional).
5, Anti-reverse connection protection make there is no reversely charging in night. Also with over-charge, limited charging current &voltage protections for battery.
6, Users can adjust the working parameters, such as over-charge, over-charge recovery voltage, delay time to cut off charging and delay time to recovery charging, etc.
7, With alarm function in system to tell the abnormal status.
8, Equipped with data communication function (optional).
9, Day and night double process mode.
10, Scientific cooling design which make the PCB board always work under best temperature environment. This will greatly increase the life of the controller.
11, Wall mounting type is easy for installation.
