2. Safety Information

Please read all instructions carefully before installation and operation. Failure to follow these instructions may result in damage to the controller, battery, or other components, and may cause personal injury.

• Ensure the battery has sufficient voltage for the controller to recognize the battery type before first installation.
• Connect the battery first, then the solar panels, and finally the load. Disconnect in the reverse order.
• Install the controller indoors, away from direct sunlight, high temperatures, and humid environments.
• Ensure good ventilation around the controller.
• The controller is suitable for lead-acid batteries (GEL, Sealed, Flooded) and Lithium batteries. Do not use for other battery types.
• All connections should be tight to avoid excessive heat due to loose connections.
• This device is for off-grid solar systems only.
