Generator runs 30 minutes, shuts off

[Rene T]

The shut down after 30 minutes uses may be when the a/c cycles off. The generator then speeds up the frequency goes too high and the monitoring cct shuts the generator down. In the manual is a procedure  to adjust the frequency.  You will need a meter to measure frequency.
