Malfunction: Vac too low or Vac too high
Possible cause Remedy
Mains voltage too low / too high Check mains voltage
Malfunction: Vdc too high
Possible cause Remedy
The solar generator voltage exceeds
the permissible value
(see Technical data)
Immediately disconnect the DC
insulation switch
Check module configuration
Alarm: Failure fan 1
Possible cause Remedy
Internal temperature too high or
internal fan faulty
For recurring faults contact the
SolarMax hotline
(A faulty fan leads to power reduction
or even total shutdown.)
Alarm: Failure fan 2
Possible cause Remedy
Internal temperature too high, or
external fan faulty
For recurring faults contact the
SolarMax hotline
Alarm: Failure temp. sensor
Possible cause Remedy
Internal temperature too high or
temperature sensor faulty
For recurring faults contact the
SolarMax hotline
Alarm: Temp. limitation
Possible cause Remedy
Internal temperature too high: device
reduces output. Check function of the
external fan; check and clean the fan

IRRADIANCE TOO LOW Wait until irradiance is high enough
5.3 Maintenance
The SolarMax inverters generally operate maintenance-free. However, we recom-
mend checking the AC output in the LC display during strong irradiance at regular
intervals.
The cumulative operating and kilowatt hours provide additional information about
the performance of your PV system.
A faulty external fan can be replaced without having to open the device: simply
release the four fastening screws of the fan and open the cable plug.
Before changing the external fan disconnect the DC circuit breaker and the AC
side!
