I apologize if my lack of knowledge has misled you. At first I thought I had connected my vawt incorrectly and that that is what caused the problem. I'd been making the diode circuits that convert AC to CD current. Being a neophite, I connected the coverted windmill output to the wires that carry my solar panel current to the charger that feeds my five 12 volt deep cycle marine batteries. I then learned that I should not do that, so I disconnected the windmill from that circuit. The solar panels are fine and continue to generate good power. However, I noticed that my Xantex XPower 1000 watt inverter died. So, I wrongly concluded and reported to you that I had connected the windmill power backwards and that is what I thought killed the inverter. I was wrong. I don't know what killed it, but something did and the likely culprit is me and my ignorance. I appreciate your help, suggestions and above all patients with my stumbling up the learning curve.
