Hi, Its great to see a forum like this thanks for your efforts and thinking that PF can help me a lot. I Am ANANTH pursuing 3-2 B.TECH under J.N.T.U.H i am working on a project of wind energy to electrical energy. but the problem is what type of dc generator(rating) should i use? first i've decided about inverter and the rating of it goes here, OUTPUT:- 3500 watts continuous power 7000 watts peak power 15.9 Amps 220 volt AC 50hz frequency. but the INPUT at rating side is given as:- 12-15v dc no load draw <1.2amps now the problem is at input side for 12v dc,for achieving output of dc generator as 12v dc, to get the desired output of inverter, what rating of dc generator should i use.how much amps should dc gen should it deliver to inverter and what should be the wattage rating of it.
