I have a 1.5kkw 6 panel solar system... 10 years old so it now only pulls about 750w (half). It still works though. I want to get a new 6.6kw system. Does anyone know if the two can run successfully side by side at my house? Also... while I am at it. Can that happen (or even just the 6.6kw system) on my single phase power connection? Any ideas or experience out there?ThanksPaul
