What does 'RTC error' mean on my SolarMax 13MT2 Inverter?
An RTC error means that the real-time clock in the inverter is malfunctioning, and the date and time have been reset. If this problem happens frequently, contact the SolarMax Service Centre. Set the time and date correctly.
Why does SolarMax 13MT2 show 'Vdc too high' error?
The 'Vdc too high' error on your SolarMax Inverter indicates that the DC input voltage at the specified DC connection is exceeding the acceptable limit. To resolve this, immediately switch off the DC disconnector Q1 and disconnect the PV generator from the inverter. Then, thoroughly check the dimensioning of the PV generator to ensure it is within the inverter's specified operating range.
What to do if SolarMax 13MT2 Inverter shows 'No mains' error?
If your SolarMax Inverter displays a 'No mains' error, it means either there is no mains voltage present or the AC supply has been interrupted. To resolve this, check the AC supply to ensure it is properly connected and functioning.
What does 'Insulation fault DC' mean on my SolarMax 13MT2?
The 'Insulation fault DC' error on your SolarMax Inverter indicates that the insulation resistance of the PV generator against earth is too low. In this case, you should check the PV generator.
What does 'Program Firmware' mean on my SolarMax Inverter?
This indicates that the inverter firmware is currently being updated. The inverter automatically resumes mains operation once the firmware update is complete.
Why SolarMax 13MT2 Inverter shows 'Firmware mismatch'?
The firmware versions of the inverter controllers do not match. Contact the SolarMax Service Centre.
What to do if my SolarMax Inverter displays 'Insulation fault DC Insulation fault DC BP'?
This indicates that the insulation resistance of the PV generator against earth is too low. Check the PV generator to resolve this issue.
What to do if SolarMax 13MT2 Inverter shows 'Vac 10min too high (L1 L2 L3) Vac 10min too high BP (L1 L2 L3)'?
The maximum 10-minute average value of the mains voltage at the specified phase is too high. If this problem continues to occur, contact the responsible grid operator.
What to do if SolarMax 13MT2 Inverter displays 'Program Firmware'?
If your SolarMax Inverter displays 'Program Firmware', it means the inverter firmware is currently being updated. The inverter automatically resumes mains operation once the firmware update is complete.
What does 'Error DC polarity' mean on SolarMax 13MT2 Inverter?
If your SolarMax Inverter displays 'Error DC polarity', it indicates that one or more DC connections are connected incorrectly. Correct this by ensuring that you connect the DC supplies correctly.
