Important Safety Information

❖ It is better to install controller in the room. If install 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 Voc of solar panels is high (especially 24V/48V system, please take care

❖ The battery had acidic electrolysis, please put on goggles during installation. If you accidentally exposed to 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:)
