Hi Ante! Why 12V. First of all I have allready two 1,4 kW continues (2,8 kW surge)/12V-220V/50Hz modified sine-wave inverters. Second to get some power from wind turbine in low winds (4-5 m/s I can get littlebit over battery bank charching voltage) I have to have as low battery bank voltage as possible. But I am open to other ideas as well. If you say that it is relativelly easy to build an inverter 3 kW(6 kW surge)/96V....-220V/50 Hz and boost converter I will choose this way.

Hello All! I am new here. I know some basics about electronics but it was quite long time ago I made something by myself. At the moment I am interested in small scale wind power. I have built a "small" wind generator where I used permanent magnet DC servo motor as generator. The generator puts out 0..100V and maximum power is about 1 kW. I would like to know is it visible to build buck-boost converter which turns input voltage 5-100V into usable voltage for 12V battery bank loading (about 15-18V)? Any ideas?

Hello! I do not know why you need such a big inverter. It is uneconomical to build a large inverter (I have seen in eBay.de for sale modified square wave inverter 8kW continues and 16kW surge for about 300EUR). Do you have one big load or many smaller? I have different small loads and I bought instead of one big inverter few smaller ones which was more economical way to go.
