What should I do if my SolarMax Inverter shows 'Vac too low or Vac too high'?
If your SolarMax Inverter displays 'Vac too low' or 'Vac too high', the cause may be that the mains voltage is too low or too high. Check the mains voltage to ensure it is within the appropriate range.
Why is my SolarMax S series Inverter showing 'Overtemperature'?
If your SolarMax Inverter is showing an 'Overtemperature' warning, this could be due to several reasons. The ambient temperature might be too high, or there may be insufficient air circulation. Ensure air can circulate at the side of the cooling fans. If a fan is blocked, clean or replace it.
What does it mean if my SolarMax S series Inverter displays 'Insulation fault'?
If your SolarMax Inverter is showing an 'Insulation fault', it could be due to earth leakage or an insulation fault on the DC side. Check the solar generator and DC cabling. It may also be due to phase and neutral conductors being interchanged; in that case, swap the phase and neutral conductors in the AC coupling connector.
What to do if my SolarMax S series Inverter displays 'Vdc too high'?
If your SolarMax Inverter displays 'Vdc too high', it indicates that the solar generator voltage exceeds the permissible value. Immediately disconnect the DC insulation switch and check the module configuration.
What to do if my SolarMax Inverter displays 'Ierr too high'?
If your SolarMax Inverter displays 'Ierr too high', it means the fault current is too large. Check the solar generator and DC cabling. It may also indicate an earth leakage or insulation fault on the DC side, in which case you should ensure equipotential bonding between the inverter and module frame.
How to fix a SolarMax S series with no graphics display?
If your SolarMax Inverter has no graphics display, it could be due to several reasons: * The DC insulation switch may be switched off. If so, switch it on. * The irradiance may be too low. Wait until irradiance is high enough. * Strings may be interrupted. If so, rectify the interruption. * It could be an internal fault. If so, notify the SolarMax hotline.
Why is my SolarMax Inverter flashing and displaying 'Irradiance too low'?
If the graphics display on your SolarMax Inverter flashes periodically or shows a status message indicating 'Irradiance too low', it means that the irradiance is too low. Wait until the irradiance is high enough for normal operation.
What does it mean when the alarm LED on my SolarMax Inverter is flashing green/red?
If the alarm LED on your SolarMax Inverter is flashing green/red, it indicates a temperature limitation. The inverter output is reduced when the heat sink temperature reaches 75 °C.
What does it mean if my SolarMax S series Inverter displays 'Iac asymmetric'?
If your SolarMax Inverter displays 'Iac asymmetric', it indicates that the DC component of the mains current is too large. First switch off the AC side and then the DC side for 20 seconds, then switch it on again. For recurring faults, contact the SolarMax hotline.
What should I do if my SolarMax S series displays 'No mains, frequency too high or too low'?
If your SolarMax Inverter displays 'No mains, frequency too high or too low', it could be due to a grid or mains voltage interruption. Check the AC connection. It could also be that the mains frequency is outside the tolerance; in that case, wait until the mains frequency is within tolerance.
