4.7 Alarm signals
The alarm messages are displayed in the graphics alternately with the status mes-
sage. An alarm does not lead to shutdown, although loss of yield is to be expected.
The LED display flashes green and red if an alarm is present. As long as the inverter
does not operate in mains mode the alarm message is only displayed in the graph-
ics display. In this case the LED display indicates the current device status.
The following table shows the possible alarm messages:

5 Troubleshooting
5.1 Introduction
Sputnik Engineering only supplies SolarMax inverters that have passed our exten-
sive tests. Furthermore, for each device a long-term test under full-load conditions
is carried out over several hours.
In the unlikely event of your PV system being affected by a fault we recommend the
following procedure:
1. Ensure that the solar generator is correctly installed and connected to the
mains. Check the connections and the procedure described in Section 2
(Installation).
2. The integrated graphics display facilitates troubleshooting. Further details are
provided in the following subsection.
3. Contact our SolarMax hotline if you are unable to rectify the fault with the
suggested measures.
