4.2 Wiring Sequence
Follow this sequence for safe and proper connection:
- Connect the Battery: First, connect the battery to the controller's battery terminals (BATT+/-). Ensure correct polarity. The controller will power on.
- Connect the Solar Panel: Next, connect the solar panel array to the controller's PV terminals (PV+/-). Ensure correct polarity.
- Connect the Load: Finally, connect the DC load to the controller's load terminals (LOAD+/-).
- Optional Connections: If using, connect the Remote Temperature Sensor (RTS) to the RTS port and any communication cables (e.g., RS485) to the COM port.
Important Safety Note: Always disconnect the solar panel first, then the battery, when performing maintenance or disconnecting the system. Reconnect in reverse order: battery first, then solar panel.
5. Operating Instructions

7. Troubleshooting
This section provides solutions to common issues you might encounter with your solar charge controller.
| Problem | Possible Cause | Solution |
|---|---|---|
| Controller not powering on | Battery not connected or reverse polarity; Battery voltage too low. | Check battery connections and polarity. Ensure battery voltage is above the minimum operating voltage. |
| No charging from solar panel | Solar panel not connected or reverse polarity; Insufficient sunlight; PV array voltage too low/high. | Check PV connections and polarity. Ensure adequate sunlight. Verify PV array voltage is within the controller's input range. |
| Load not working | Load disconnected or reverse polarity; Load current exceeds rating; Battery voltage too low (LVD). | Check load connections and polarity. Reduce load or use a higher rated controller. Charge battery. |
