I am currently in the process of installing an SMA SunnyBoy 7.6 KW (Grid-Tie split phase 120/240v) system, with 30 Qcell 320 watt panels. I am awaiting my permit to finish install and to get the power company to reprogram my meter to read backwards. Right now I have 15 panels on my roof "testing the system", and can see that I am not getting enough power to cover all my current needs, plus future needs. When I bought the panels I originally bought used Canadian Solar panels, however they kept tripping the Ground fault Isolation on the Sunny Boy. The seller took them back and made me a good deal on the New Qcells that I now have. He had 43 of them and so I took them all. 30 panels will put me at max with the Sunny Boy (slightly over-paneled) so I intend to add a second inverter.
So this is my question and what I want to do. I want the second inverter to be a Hybrid. Under normal conditions it will be A/C coupled/grid-tied and create enough electricity that I can cover all my electric needs including being able to run the A/C in my shop 24/7 to keep the humidity here in Central Florida under control. Then when the grid goes down, I can Isolate from the grid run the Hybrid Inverter in Off-grid mode, and it should trick my SunnyBoy into turning on and connecting. Later I can add batteries/generator into the system for night time off-grid coverage.
It looks like the Grid-Tied Inverter Delta H6 6000W can do everything I need. I called the Ebay seller of them and they thought it could, but didn't want to commit to it. What do you guys think?
