SAFETY INSTRUCTIONS 1. Ensure your battery has sufficient voltage for the controller to recognize the battery type before initial installation. 2. The battery cable should be as short as possible to minimize loss. 3. The regulator is only suitable for lead-acid batteries: OPEN, AGM, GEL; it is not suitable for nickel-metal hydride, lithium-ion, or other batteries. 4. The charge controller is only suitable for regulating solar modules. Never connect another charging source to the charge controller. SYSTEM CONNECTION 1. Connect the battery to the charge controller (plus and minus). 2. Connect the solar module to the controller (plus and minus). 3. Connect the consumer to the controller (plus and minus). The reverse order applies during uninstallation. Incorrect order may damage the controller.
