Safety Precautions

Please read and understand all safety instructions before installation and operation. Failure to follow these instructions may result in electric shock, fire, or severe injury.

• Ensure all connections are tight and correct polarity is observed to prevent damage to the controller or other components.
• Always disconnect the solar panel and battery power before installing or adjusting the controller.
• Install the controller in a well-ventilated area, away from flammable materials and direct sunlight.
• Do not disassemble or attempt to repair the controller yourself. Contact qualified personnel for service.
• Use appropriate circuit breakers or fuses for all connections to protect against overcurrent.
• Wear appropriate personal protective equipment (PPE), such as insulated gloves and eye protection, during installation.

Setup and Installation

Follow these steps carefully to install your MT3075 Solar Charger Controller. The correct connection order is crucial to prevent damage.

1. Prepare Wiring: Ensure all wires are of appropriate gauge for the current and length, and that their ends are properly stripped and tinned or fitted with the provided connection terminals.
2. Connect Battery: Connect the battery to the controller's battery terminals (+ and -). Ensure correct polarity. The controller will power on once the battery is connected.
3. Connect Solar Panel: Connect the solar panel to the controller's solar panel terminals (+ and -). Ensure correct polarity.
4. Connect DC Load: Connect your DC loads to the controller's load terminals (+ and -). Ensure correct polarity.
5. Connect Temperature Sensor: Plug the external temperature probe into the designated port on the controller. This ensures accurate temperature compensation for battery charging.
6. Verify Connections: Double-check all connections for tightness and correct polarity before applying full power.
