Can anyone here recommend a good forum for research of FYI solar PV systems? I'm planning/designing a grid-tied PV system system that uses a high voltage input (string) inverter. I'm going the string inverter route with hopes of being able to employ our hybrid vehicle as a backup generator. It looks like I may be able to connect the PV array to one inverter MPPT input full-time and the hybrid vehicle to another MPPT input only when emergency power is needed. The PV array would be series wired for about 300VDC to decrease line losses and conductor size. Shading is not an issue. The Sunny Boy US series inverter is one I'm considering for this. http://www.sma-america.com/en_US/products/grid-tied-inverters/sunny-boy/sunny-boy-5000-us-6000-us-7000-us-8000-us.html Any advice/thoughts from folks here WRT my plans would be greatly appreciated also.
