Cost by the time it came out for actual purchase was the first one. When it was announced the cost (as I recall it) seemed quite reasonable for the capabilities. Then the inverter size was severely undersized with no real ability to power a full sized home without making large sacrifices. Around 9kw if I recall correctly, which means (for me at least) no running A/C and a large electric appliance at the same time like a dryer. Then it required using Sunrun as the only system integrator - plus all their equipment. I guess this is to be expected, but I'd like to design my own system. I'm in the same boat as you though - I never looked into beyond surface level since I have enough random projects to think about as it is, and no property yet to turn any research into a practical system.
