List

Below you will find a list of common error messages from various brands. Not all error messages are listed here. It is advisable to also consult the manual of the device.

Brand Error code Cause Action
______________ ____________________________ _________________________ ________________________________________________________
Solarmax The display remains blank DC disconnector Q1 is switched off. Switch on DC disconnector Q1.
Solarmax The display remains blank Irradiation too low. Wait until the irradiation is sufficient.
Solarmax The display remains blank Strings disconnected. Check PV generator and correct disconnection.
Solarmax The display remains blank Internal failure. Contact inverter service
Solarmax The display remains blank The PV generator is connected incorrectly (plus and minus connections have been mixed up). Connect the PV generator properly.
Solarmax Failure fan A fan is defective or dirty. Contact inverter service
Solarmax Temperature limitation The feed-in power has been temporarily reduced to limit the temperature of the inverter. Clean the fan grids and improve ventilation in the operations room.
Solarmax Failure temp. sensor A temperature sensor in the inverter has failed. Contact inverter service
Solarmax Burst error The inverter disconnected from the grid five times or more on the same day. The warning is displayed for the remainder of the day. The error counter will be reset when the system is restarted in the morning. Arrange for an electrician to check the grid instantaneous voltage and grid frequency. If you consider them to be in order, contact inverter service
Solarmax RTC error The RTC (real-time clock) in the inverter is malfunctioning, the date and time have been reset. If problem occurs repeatedly, contact inverter service
Solarmax Flash error A flash error has occurred. Inverter mains operation continues to be guaranteed. Contact inverter service
Solarmax Firmware mismatch The firmware versions of the inverter controllers do not match. Contact inverter service
Solarmax Vdc too high (VDC3, VDC2, VDC1) The DC input voltage at the specified inverter DC connection is too high. Switch off the DC disconnector Q1 immediately and disconnect the PV generator from the inverter. Check the dimensioning of the PV generator.
Solarmax No mains No mains BP There is no mains voltage or the AC supply has been interrupted. Check the AC supply.
Solarmax Mains error Mains error BP The grid has been switched off. Arrange for an electrician to check the grid instantaneous voltage and grid frequency. If you consider them to be in order, contact inverter service
Solarmax Frequency too high Frequency too high BP The mains frequency is outside of the f max 1 or f max 2 limit values. As long as the inverter is detecting a grid line to line over voltage: check the line to line voltages (with a true RMS measurement device). As long as you consider line to line voltages to be in order, contact inverter service
Solarmax Frequency too low Frequency too low BP The mains frequency is outside of the f min 1 or f min 2 limit values. As long as the inverter is detecting a grid line to line over voltage: check the line to line voltages (with a true RMS measurement device). As long as you consider line to line voltages to be in order, contact inverter service
Solarmax Vac too high (L1 L2 L3) Vac too high BP (L1 L2 L3) The mains voltage at the specified phase is outside of the Vac max 1 or Vac max 2 limit values. As long as the inverter is detecting a grid line to line over voltage: check the line to line voltages (with a true RMS measurement device). As long as you consider line to line voltages to be in order, contact inverter service
Solarmax Vac too low (L1 L2 L3) Vac too low BP (L1 L2 L3) The mains voltage at the specified phase is outside of the Vac min 1 or Vac min 2 limit values. Arrange for an electrician to check the grid instantaneous voltage and grid frequency. If you consider them to be in order, contact inverter service
Solarmax 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 (Vac 10 min max.) at the specified phase is too high. Do nothing. The inverter will acknowledge the error auto matically. If problem occurs repeatedly, contact inverter service
Solarmax df/dt too high The change in the mains frequency per second has exceeded the maximum admissible value df/dt max. Do nothing. The inverter will acknowledge the error auto matically. If problem occurs repeatedly, contact inverter service
Solarmax Insulation fault DC Insulation fault DC BP The insulation resistance of the PV generator against earth is too low. Check system isolation. If you consider the isolation impedance to be in order, contact inverter service
Solarmax Ierr too high Ierr too high BP The DC leakage current has exceeded the admissible absolute limit value lerr max. Check the PV generator.
Solarmax Ierr step too high Ierr step too high BP The DC leakage current has exceeded the admissible step value. Please check the DC wiring and measure. If you consider the wiring to be in order, contact inverter service
Solarmax L and N interchanged A phase and the neutral conductor are incorrectly connected (interchanged). Please check the AC wiring and measure. If you consider the wiring to be in order, contact inverter service
Solarmax Error DC polarity One or more DC connections are connected incorrectly (incorrect polarity). Please check the DC wiring and measure. If you consider the wiring to be in order, contact inverter service
Solarmax Error ext. input 1 The external grid monitoring and/or remote shutdown has disconnected the inverter from the grid. If constant, contact inverter service
Solarmax Device error (+ error code) An internal error has occurred in the inverter. Contact inverter service
Solarmax External blocking There is a 0% command from MaxRemote (coming from the grid operator). Do nothing. The inverter will acknowledge the error auto matically. If problem occurs repeatedly, contact inverter service
Solarmax Program Firmware An internal error has occurred in the inverter. The inverter firmware is currently being updated.
Solarmax Error 42 An internal error has occurred in the inverter. Contact opnemen met omvormer service
Solarmax Error 11 An internal error has occurred in the inverter. Contact opnemen met omvormer service
Solarmax Error 13 An internal error has occurred in the inverter. Contact opnemen met omvormer service
