OPERATION INSTRUCTIONS

• The first step is to connect the battery: if the connection is correct, the controller screen will light up, otherwise, please check whether the connection is correct.
• The second step is to connect the solar panel: if there is strong enough sunlight (the voltage of the panel is higher than the voltage of the battery), the sun icon on the LCD screen will light up, otherwise, please check whether the connection is correct.
• The third step is to connect the load: connect the load cable to the load output terminal of the controller, and the current should not exceed the rated current of the controller.
• The controller will generate heat during operation, and it is recommended to install it in a ventilated and heat-dissipating environment.
• Select cables with sufficient capacity to avoid excessive loss on the line and misjudgment by the controller.
• A common positive electrode design is applied in the controller. If grounding is required, please ground the positive electrode.
• It is important to fully charge the battery frequently. The interval should be at least once a month, otherwise, it will suffer permanent damage. The battery can only be fully charged when more energy enters the battery than used by the load. Users should keep this in mind when configuring the system
• Please check whether each wiring terminal of the controller is locked, otherwise, the terminal will be vulnerable when the current is excessive.
