What to do if my SolarMax Inverter shows 'Vdc too high'?
If your SolarMax Inverter displays 'Vdc too high', it means the DC input voltage is too high. To resolve this, switch off the DC disconnector and then check the PV generator's configuration.
What to do if my SolarMax SM30HT4 displays 'No mains'?
If your SolarMax Inverter displays 'No mains', it indicates that there is no mains voltage. Check the AC input conductor (fuses) to solve this issue.
What does it mean if my SolarMax Inverter shows a 'DC insulation fault'?
If the SolarMax Inverter indicates a 'DC insulation fault', it means the insulation resistance of the PV generator to ground is too low. Check the PV generator. Also, ensure that the AC input conductor is connected correctly, as described in Section 5.3, in case the phase and neutral conductors are inverted.
What should I do if my SolarMax SM30HT4 Inverter displays 'Ierr too high'?
If your SolarMax Inverter displays 'Ierr too high', the ground leakage current has exceeded the permissible RBCM-THR limit value. To fix this, check the PV generator.
How to fix a blank graphics display on my SolarMax SM30HT4 Inverter?
If the graphics display of your SolarMax Inverter remains blank, it could be due to several reasons. First, check if the DC disconnector is switched off and switch it on. If it is on, the irradiation might be too low, so wait until irradiation is high enough. Also, all DC input conductors (strands) might be interrupted, so check the PV generator and eliminate the interruption. If none of these solve the problem, it is possible that the inverter is defective, then contact the SolarMax Service Center.
What does it mean when my SolarMax Inverter says 'Frequency too high'?
If the SolarMax Inverter displays 'Frequency too high', it means the mains frequency is outside the GFMMAX1-THR, GFMMAX2-THR or GPTFMAX-THR limit values. If this problem recurs, contact the grid operator.
Why does the graphics display on my SolarMax SM30HT4 only flash briefly?
If the graphics display of your SolarMax Inverter only flashes briefly, it is likely that the irradiation is too low. Wait until irradiation is high enough.
What to do if my SolarMax Inverter is showing a 'Mains error'?
If the SolarMax Inverter shows 'Mains error', it means the inverter detects island mode. If this problem recurs, contact the grid operator.
What causes temperature limitation in my SolarMax SM30HT4 Inverter and how to resolve it?
If your SolarMax Inverter is experiencing temperature limitation, the output power is temporarily reduced to limit the inverter's temperature. Ensure that the recommended maximum ambient temperature is not exceeded and that the cooling fins are free from dust and dirt.
What does 'RTC error' mean on my SolarMax SM30HT4, and how can I fix it?
If your SolarMax Inverter displays 'RTC error', the date and time in the RTC (real-time clock) were reset due to a failure. Set the date and time (see Section 6.4.2). If this problem occurs frequently, contact the SolarMax Service Center.
