4. Setup and Installation
4.1 Mounting Location
Choose a mounting location that is:
- Well-ventilated to dissipate heat.
- Protected from direct sunlight, high temperatures, and moisture.
- Accessible for maintenance and wiring.
- Close to the battery, but in a separate, well-ventilated compartment if possible, to avoid battery gas corrosion.
4.2 Wiring Sequence
Follow the wiring sequence carefully to prevent damage. Always connect the battery first, then the PV array, and finally the load.
- Connect the Battery: Connect the battery to the controller's battery terminals. Ensure correct polarity.
- Connect the PV Array: Connect the solar panels to the controller's PV terminals. Ensure correct polarity.
- Connect the Load: Connect the DC load to the controller's load terminals. Ensure correct polarity.

6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your solar charge controller.
- Check Connections: Periodically inspect all wiring connections for tightness and corrosion. Tighten any loose connections.
- Clean the Controller: Keep the controller clean and free from dust and debris. Use a dry cloth for cleaning. Do not use liquids.
- Inspect for Damage: Check for any physical damage to the casing, wires, or terminals.
- Ventilation: Ensure that the ventilation openings are not blocked to allow for proper heat dissipation.
- Battery Health: Monitor battery voltage and health. Ensure batteries are properly ventilated.
7. Troubleshooting
If you encounter issues with your controller, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No display/No power | Battery not connected or reverse polarity; Battery voltage too low. | Check battery connections and polarity. Ensure battery voltage is above minimum operating voltage. |
| No charging | PV array not connected or reverse polarity; PV voltage too low; PV array shaded. | Check PV connections and polarity. Ensure PV voltage is within operating range. Clear any shading. |
| Load not working | Load not connected or reverse polarity; Load overcurrent/short circuit; Battery voltage too low. | Check load connections and polarity. Reduce load or check for short circuits. Charge battery. |
| Controller overheating | Poor ventilation; Excessive ambient temperature; Overload. | Ensure adequate ventilation. Relocate controller if ambient temperature is too high. Reduce load. |
If the problem persists after attempting these solutions, please contact EPEVER customer support or your local dealer.
