I thought I would start a new thread after seeing a few videos. I currently am running that CTP-1000w 120 volt Hybrid for wind and solar. It draws no power at night. It charges the internal capacitors then puts watts into the grid. It will not lock on till at least 40 watts. If you disconnect it without shutting it off. Then plug it back in it will fry. Fans are really noisy on this unit. They run all the time at approx 200 watts. Update At 300 Watts the GTI Fried. So what is everyone else using and what do you have to share here?
