10 Troubleshooting
Sputnik Engineering delivers only SolarMax inverters which have stood up to our exten-
sive testing regime. Moreover, each inverter is subjected to several hours of endurance
testing under full-load conditions.
This section describes in several tables all the possible error messages, their possible
causes and suggestions on how to remedy them.
If despite this your PV power plant suffers a malfunction or an error we recommend these
procedures:
1. Check whether the inverter and PV generator have been installed correctly.
2. Check the cable connections and follow the points described in section 4, “Installa-
tion”.
3. Determine the cause of the failure by checking the message in the graphics display.
Section 10.2, “Diagnosis & corrective steps” explains possible ways of correcting mal-
functions.
4. If you cannot correct the malfunction using the recommended procedures, or you are
not sure what sort of fault is involved, please contact our SolarMax Service Centre.
