SW fans [RE-wrenches]

[R. Sparks Scott]

>How about it Sparkey.  Does the relay idea sound ok?

	John;

	If you're asking my approval, I'd say go for it. The only time I've ever
seen the fans on my SW run is during heavy generator charging (80-120 amps)
and during  some unusual high-current PV episodes when it was trying to
send 90 amps of DC back into the grid as AC to keep the batteries
regulated. I see PV inputs of 70-75 amps daily, and the fans never seem to
run.
	A slightly better (and long-term *safer*) solution might be to install a
thermostat with the sensor attached to the heat sink inside the cabinet. WW
Graingers should have something that would work, or a circuit with an LM34
and a comparitor chip could be built for next to nothing (sounds like a
perfect HP Homebrew project, anybody got the index of issues handy, maybe
there is already one designed?)
