Need help !!!! has anyone had experience with the grid tie inverters ? I am looking at the small turbine type ( plug and play) So far I have searched out a few but I am having difficulty understanding the specs, especially when it comes to DC in. You can find the same product but each seller might offer a different set of specs on incoming DC. I will paste below a set of specs on one item . note the DC - IN Volts . I will also paste specs from the same page in brackets below this. The Kit includes the following components... * A 250 watt grid tie inverter * A Diode box * A Dump load box * An AP box to stack more inverters( up to 3 additional inverters) STARTER-KIT CAN BE EXTENDED WITH MAX. 3 EXTENSION UNITS UWT-I-250 EXTENTION-KITS UP TO 1 KW. DC-IN: 0-55V, AC-OUT: 120/230V 60/50HZ. WIND TURBINES MODELS (with Peak Watts) THAT CAN BE CONNECTED ARE 200W-300W-500W-750W AND 1 KW. So what is it 20V - 54V or 0 - 55 V ? When I write and ask the seller questions I am either getting no response or answers I know are completely from outer space. I realized there are persons who sell but don't really know a great deal about the product. ( they are not using what they sell) So without going on and on, with all my questions, I am hoping someone out there can join in and enlighten some of us. Oh yes and when the say you can turn your meter backwards and sell back to the utility company, that is a whole other story !!
