2. Safety Instructions
Observe the following safety precautions during installation and operation:
- Ensure all circuit breakers or fuses are open before wiring the controller. Verify correct polarity for all connections (positive '+' and negative '-').
- Install a fuse on the battery side with a current rating 1.25 to 2 times the controller's rated current. The fuse should be located no more than 150 mm from the battery.
- For installations in areas prone to lightning strikes or unattended locations, an external surge arrester must be installed.
- If an inverter is part of the system, connect it directly to the battery terminals, not to the load terminals of the controller.
- Avoid touching exposed wires or terminals when the system is operational.
- Ensure proper ventilation around the controller to prevent overheating.

- Firmware Updates: Check the EPEVER website for any available firmware updates to improve performance or add features.
8. Troubleshooting
If you encounter issues with your controller, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No display on LCD | Battery not connected or low voltage; reverse polarity. | Check battery connections and voltage. Ensure correct polarity. |
| Battery not charging | PV array not connected; low PV voltage; PV reverse polarity; faulty PV module. | Check PV connections and voltage. Verify PV polarity. Inspect PV modules. |
| Load not working | Load disconnected; overload; short circuit; low battery voltage. | Check load connections. Reduce load. 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. |
For more detailed troubleshooting or persistent issues, please consult the comprehensive user manual or contact EPEVER customer support.
