I placed an order last week for a 4kwh system because 8 kwh is too large for us, at the time 4 is not enough. I got the email to upload pictures of my panel and meter, but the design email came through before I uploaded the pictures - weird. I have not accepted the design because I would like upsize my system to a 5 or 6. Do I do this now? Or, with who? My site inspection is tomorrow.
