Wind generator and refridge question

[ereiss]

Is there a way to install a wind machine so that when there is wind the refrigeration works but the refrigeration shuts off when enough power isn't being produced?

I haven't purchased a wind system yet but was wondering if there was a way to ensure a cold fridge when I arrive on the boat.

Thank you for your help.

Yes, this is possible. The simplest solution would be to have the wind generator hooked up to nothing but the refrigeration system (and a heat-sink diode). The fridge would have a cutoff voltage below which it wouldn't try to start. There are lots of downsides to this (compressor startup requires more power than while running, excess power goes to waste (heat) when the windgen produces more power than the fridge needs or when the fridge is cold enough.
Another method would be to have a battery in the loop for the fridge, this way there is a bit of power buffering.
The best is to wire the windgen into your house battery system, and then put a restrictive startup voltage on the fridge - i.e. it would only turn on when voltages are above the normal battery voltage, i.e. when it is being charged.
I think that the Danfoss compressors, which are in common use, have a simple resistor which regulates their minimum accepted voltage.
