The initial load taken by the compressor of a GSHP can cause sufficient fluctuation in the grid voltage for the inverter to see it as a disconnection, which can cause the inverter to reset itself. If this happens when the turbine is generating then you will loose the output. Be sure you have over-voltage protection on the DC input to the inverter to allow for this.

You can get soft-start devices for the GSHP that will help with the problem too.
