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 congured, 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.
