I managed to build the charge controller (to check the charging process), the Low Voltage Disconnect (to check the discharge process), and encase them so that it looks good. Wiring everything, so that it doesn't burn when it is ON, was a challenge by itself. By the way, both charge controller and LVD are using the same board made my Glen. The calibration process is a little bit akward for the LVD but once you have everything set, it works just great. The 4 batteries (12V 7Ah) terminals are connected in parallel with the same cable lenght. I read somewhere on the web that it was the best configuration to have a well balanced charge and discharge process as far as batteries voltage are concerned. The next step is to improve my wind turbine. It should be able to keep the batteries charged enough to run the inverter at the same time. After that I would get good batteries and test everything together.

DIY Wind Turbine - Charge Controller
This step would have been to build a microcontroller -based Charge Controller for my battery bank using a LM3S811 evaluation board that I already have. Instead, Glen hurd, a veteran of RE had a track proven, really cheap and easy to understand controller that I fell in love with. Beside, let's not reinvent the wheel ! It only cost 15 bucks (check it out at ghurd.info and you get great technical support along. I used it and there it is; Working. Will keep you posted
