number Event, cause and corrective measures
7001 Fault sensor interior temperature (7001)
The temperature sensor for the indoor temperature of the Sunny Multigate is defective.
Feed-in operation will be interrupted.
Corrective measures:
• Contact the SMA Service Line.
7702 Self diagnosis > Interference of device (7702)
A relay error has occurred.
Corrective measures:
• Disconnect the Sunny Multigate from voltage sources (see Section 10, page 50)
and re-commission it (see Section 7, page 42).
• If this message is still displayed, contact the SMA Service Line.
8101 to
8102 Communication disturbed (8101, 8102)
An error has occurred in the internal communication. This can be caused by one of the
following: Feed-in operation continues.
Corrective measures:
1. If several Sunny Multigate devices are installed in a system, check whether the
AC cables from the inverters to the Sunny Multigate devices have been laid in
separate channels. If the AC cables are not laid separately from each other, lay
the AC cables from the inverter to the Sunny Multigate in separate locations.
2. If the problem persists, contact the SMA Service Line.
