Thanks all;

Looks like I dug up a good topic. First, this installation is not on 
airport property, it is not a large airport, and my installation is not 
subject to the scrutiny that some of your previous installations had. (This 
is next door is a 30 ft two way radio transmitter for instance). So 
basically Bill is saying don't put the inverter on board the aircraft, and 
John is saying that every install I have done is a potential hazard to low 
flying aircraft. I am very interested in this. Lets cut to the chase, which 
inverters have FCC compliance, and which have serious interference 
problems. Can we talk brands and models now?
Also, for watt-sun trackers, I agree with your comments William. I replaced 
Watt-Sun controllers damaged from lightning many times. This site will be 
under my watchful eye, so any failures will only last a day or two at most. 
As for accuracy, I used these on concentrator systems that required extreme 
accuracy. I've found the Watt-suns do the job right out of the box. I have 
not experienced the sensor degradation problem.
