Important Safety Information


It is better to install the controller in the room. If installed the controller outside, please keep the environment dry, avoid direct sunlight.

The controller will be hot in process of working, please keep the environment ventilation, away from flammable.

The open circuit voltage of solar panel is too high, (especially 24V system), please take care.

The battery has acidic electrolysis, please put on goggles during installation. If you accidentally exposed to the electrolysis, please rinse with water.

The battery has huge power, prohibit any conductor short circuit the positive and negative pole of battery. Suggest to adding a fuse between battery and controller. (Slow motion type, the action current of the fuse should be 1.5 times rated current of controller.)
