This weekend I installed a new Tristar TS-60 charge controller. The Tristar was a very easy switch from the Xantrex C40 - all the wire terminals match up and so do all the mounting holes. Seems Morningstar knows who their competition is! I've planned an upgrade from the 40-amp Xantrex for a while - considering either the Xantrex C60 or the Tristar TS-60. Since the "60-amp" Xantrex is de-rated to only 48 amps in diversion control mode, the decision swung in the Tristar's favour. It will better handle the incoming wattage from the next turbine I put up. No wind since putting it on, so I can't report it working or not.
After installing the new Tristar (which went smoothly) I noticed the other C40 (for my solar panels) going a little crazy. At first I didn't know if I was seeing the famous "edge-of-cloud" effect which magnifies sunlight intensity and gives you a few percent more power. Once the C40's display crept up from 9 amps (the short circuit current rating of my panels) to 12 amps, I knew something fishy was going on. I unplugged the C40, and after resetting it, the readings went back to normal.
Has anyone else seen this kind of weird thing happen?
