What to do if my PowMr POW-M80 Controller shows Fault Code 63 (high battery voltage)?
If your PowMr Controller displays Fault Code 63, it indicates a high battery voltage. To resolve this, you should measure the battery voltage to confirm if it exceeds the rated voltage. If it does, immediately close the photovoltaic array circuit breaker.
Why does my PowMr POW-M80 Controller show Fault Code 71 (high input photovoltaic voltage) and how to fix it?
If your PowMr Controller displays Fault Code 71, it means the input photovoltaic voltage is too high. You can fix this by reducing the number of photovoltaic arrays connected to lower the input voltage. Another option is to change the series and parallel connections to decrease the voltage or current values.
What to do if my PowMr POW-M80 displays Fault Code 65 (low battery voltage)?
If your PowMr Controller shows Fault Code 65, it indicates a low battery voltage. You should charge the battery until its voltage exceeds the undervoltage termination voltage. Refer to section "3.5 Default Parameters for Different Battery Types" to check specific values.
How to fix Fault Code 18 on PowMr Controller (low input photovoltaic voltage)?
If your PowMr Controller displays Fault Code 18, it indicates low input photovoltaic voltage. To solve this, increase the number of solar panels or connect them in series to raise the photovoltaic input voltage.
Why does my PowMr POW-M80 show Fault Code 60 (overtemperature protection) and how to resolve it?
If your PowMr Controller displays Fault Code 60, it means the device is experiencing overtemperature protection. To resolve this, allow the device to cool down below the recovery temperature. After cooling, normal charging and discharging will resume.
