6.2 Troubleshooting via the graphics display

Possible cause
DC insulation switch switched off
Irradiance too low
Internal fault
Strings interrupted
Malfunction: Graphics display fl ashes periodically, or
Status message: Irradiance too low
Possible cause
Irradiance too low
Malfunction: Overtemperature
Possible cause
Ambient temperature too high
Insuffi cient air circulation
Fan blocked
Malfunction: Iac asymmetric
Possible cause
DC component of the mains current
is too large
87
Fault: No graphics display
Remedy
Switch on the DC insulation switch
Wait until irradiance is high enough
Notify SolarMax hotline
Rectify interruption
Remedy
Wait until irradiance is high enough
Remedy
Ensure air can circulate at the side of
the cooling fans
Clean / replace fan
(see Section 5.3)
Remedy
Switch off AC side and then DC side
for 20 seconds, then switch on again
For recurring faults contact the Solar-
Max hotline
Malfunction: Ierr too high
Possible cause Remedy
Fault current too large as level-change Check solar generator and DC cabling
or absolute value
Earth leakage or insulation fault on Equipotential bonding between
the DC side inverter and module frame
Malfunction: Insulation fault
Possible cause Remedy
Earth leakage or insulation fault on Check solar generator and DC cabling
the DC side
Phase and neutral conductor inter- Swap phase and neutral conductor in
changed the AC coupling connector
Malfunction: No mains, frequency too high
or too low
Possible cause Remedy
No grid or mains voltage interruption Check AC connection
Mains frequency outside the tolerance Wait until the mains frequency is
within tolerance
Malfunction: Mains fault
Possible cause Remedy
Stand-alone operation was detected For recurring faults contact the
