4.6.4 Status signalling contact
The status signalling contact enables remote retrieval of the operating status of the in-
verter. The status signalling contact is located in the connection area of the inverter, see
4.6 Electrical connection; page 71. A suitable M12 mating connector to connect to the
status signalling contact can be ordered from the SolarMax Service Centre.
Remote retrieval of the operating status can be configured, see section “Status relay”;
page 92.

4.6.5 Monitoring external input
PV plants connected to the grid in Germany with an output of more than 30kVA require a
central grid and plant protection (G/P protection).
If the “Monitoring external input” function is activated, the grid relays of the inverter can
be used as interconnection circuit breakers of the central G/P protection. The function is
activated during initial start-up (see 5.2 Initial start-up; page 81) or subsequently using
the service software MaxTalk 2 Pro. Remote retrieval of the operating status, as described
in 4.6.4 Status signalling contact, is no longer possible when monitoring of the external
input is activated.
