HelllllP.... I just came back from studies, and found out that the Grid has reached my cabin. The electrical poles are going up as I speak. I will still raise back up my Windy500 and use the 200W solar panel I have. The last time my charge controller burnt, so I was wondering if I still need it to connect to the grid? Or do I only need a Grid tie inverter? I believe the last time that my windy500 ran without load for a couple hours. How can I check if it is still working? I connected a dc voltmeter to it and it went up 20 to 35 volts...is this ok? So I will connect to the grid! I have a windy500 and a 200w panel. What else do I need. (btw I still have my battery bank -just two 6 v 232ah battery connected in series) Thanks.
