I've been offered a solar system that a friend purchased last fall but was never able to install due to his HOA (I have no clue why he didn't get permission from the HOA before purchasing). It's a 5.2K system and I've been offered the whole lot, new in the boxes for $5K. On the surface it seems like a pretty good deal. However, it's a SunMax system from Ubiquiti which is a unique system. It converts the DC to AC at each panel using micro-inverters. I've attached a screenshot of how I'd possible install the system at my location which shows the output etc. The problem is with the "at the panel" DC-AC conversion. With a traditional system where the conversion happens at the single inverter, I could just switch my planned 3 AC Powerwalls over to DC Powerwalls. So my questions is: Would I be able to store the excess energy from this solar system in my AC powerwalls? How would that work? Perhaps charge them 2/3 overnight and let the solar fill up what it can the following day before the peak period? I'm not so much concerned about cost as I am how it would physically work. Thoughts?
