Setup and Installation
Proper installation is crucial for the safe and efficient operation of your solar charge controller. Please follow these steps carefully.
1. Mounting the Controller
The controller should be mounted in a well-ventilated area, away from direct sunlight and moisture. Ensure there is sufficient space around the unit for proper heat dissipation, especially for the cooling fan.

2. Wiring Connections
Always connect the battery first, then the solar panel, and finally the load. Disconnect in the reverse order. Ensure all connections are secure and correct polarity is observed.
- Connect Battery: Connect the battery cables to the battery terminals on the controller. Ensure correct polarity (+ to + and - to -). The controller will power on once the battery is connected.
- Connect Solar Panel: Connect the solar panel cables to the PV input terminals on the controller. Ensure correct polarity. The controller will begin charging the battery.
- Connect Load (Optional): If using the DC load output, connect your DC appliances to the load terminals.
- Connect Temperature Sensor: Connect the included temperature line to the designated temperature sensor port. This ensures accurate battery charging based on ambient temperature.
- Connect WiFi Adapter: Plug the CM-W01 WiFi adapter into the RS485 communication port.
