What to do if I cannot connect the RS-485 cable to my Renogy Controller?
If you cannot connect the RS-485 cable to your Renogy Controller, check that you are using the correct cable and port. Also, verify that the correct software is installed.
What to do if the Fault LED is blinking red and LCD displays 'Over Volt' on my Renogy Commander?
If the Fault LED is blinking red and the LCD displays “Over Volt” on your Renogy Controller, it means the solar input may be too high. To resolve this, use a multimeter to check if the solar panels are correctly sized for the controller and battery bank. The charge controller will automatically resume working once it detects the correct voltage range.
Why is the Battery LED green and blinking fast, and the LCD displaying “OVD” on my Renogy Commander Controller?
If the Battery LED is green and blinking fast, and the LCD displays “OVD” on your Renogy Controller, it indicates that the battery voltage might be higher than the over voltage disconnect voltage. To fix this, use a multimeter to check the battery voltage and disconnect the PV modules for a more accurate reading.
What to do if the Battery LED is orange (blinking) on my Renogy Commander?
If the Battery LED is orange and blinking on your Renogy Controller, it means the charge controller is operating above its maximum temperature range. To solve this, move the charge controller to a cooler location. Also, make sure you're following the correct installation steps to avoid damaging the system.
