If the batteries aren't charging, double-check that your solar panels are receiving sunlight and are connected correctly to the controller. Make sure the panel voltage is within the CPY 2420's specifications. Check the battery connections and the battery voltage itself. The controller might not initiate charging if the battery voltage is too low. On the flip side, if your batteries are overcharging, the controller might not be regulating the voltage correctly. This can happen if the charge controller is not correctly configured for your battery type. Review the controller's settings to ensure they match your battery's specifications. Also, make sure that the temperature sensor is connected and functioning correctly, especially for battery temperature compensation. Incorrect settings can significantly impact your battery life. And lastly, another common issue is the solar charge controller showing error codes, consult the CPY 2420 manual to decode and understand the error.

In addition to these, other issues can arise, such as the controller failing to recognize the solar panels or the batteries. Make sure the panels are wired correctly and that the voltage matches the controller's requirements. If the controller doesn’t recognize the batteries, check the battery terminals and ensure they are connected properly. Ensure that the polarity is correct and that the batteries are of the correct voltage. Sometimes, a software glitch can cause these issues. Resetting the controller might help. Consult your manual for the proper reset procedure. If none of these steps resolve the issue, it could indicate a more serious problem within the controller, and it’s time to call in the professionals. Always remember to prioritize safety when working with electrical equipment. Disconnect power before performing any inspections or repairs, and if you are unsure about any aspect of the troubleshooting process, seek assistance from a qualified technician.
