4. Setup and Installation
Proper installation is crucial for the safe and efficient operation of your solar charge controller. Please follow these steps carefully.
4.1 Safety Precautions
- Ensure all connections are tight to avoid excessive heat buildup.
- Install the controller indoors, away from direct sunlight, high temperatures, and water.
- Mount the controller vertically on a wall or flat surface to allow for proper air circulation.
- Use appropriate circuit breakers or fuses for the solar panel, battery, and load circuits.
- Always connect the battery first, then the solar panel, and finally the load. Disconnect in reverse order.
4.2 Wiring Sequence
- Connect the Battery: Connect the battery to the controller's battery terminals. Ensure correct polarity (+ to + and - to -). The controller will detect the system voltage.
- Connect the Solar Panel: Connect the solar panel to the controller's PV terminals. Ensure correct polarity.
- Connect the DC Load: Connect the DC load to the controller's load terminals. Ensure correct polarity.
- Connect Remote Temperature Sensor (Optional): If using, connect the RTS to the designated port. This improves battery charging accuracy.
- Connect Communication Accessories (Optional): If using an MT50 remote meter, eBox-wifi, or PC communication cable, connect it to the RJ45 port.
Important: Incorrect wiring sequence can damage the controller. Always connect the battery first and disconnect the solar panel first.
