As I collect my solar panels, I'm nearing 1KW, and had begun to consider battery costs until I took time to email our electric company to ask about a grid tie in. The local power provider is an electric Co-op here in Texas, and has said they will install a "forward and reversing KWH meter" if I complete their insurance requirements and paperwork application for "Under 10KW Co-generation". I emailed them to ask if there were types and brands of inverters they perferred, to which they said they had no company list and it was up to me as most inverter companies have improved because of the push for Green acceptance. I was very happy to hear grid tie is a real possibility, although they have no rebate program like TXU/On-Cor, a large metroplex electric company who is buying wind energy from the large wind farm in West Texas.
What grid-tie inverter of a 1.5-2KW rating is working for you, and who has the best prices and warranty service? To keep a balanced usage of this small array, should the inverter be a 220v version so it provides to both legs of the incoming power?
