So I currently have a two Solar System. One is an old 7kwh String inverter System and the second is a Sunpower 8.7 System with a Tesla Powerwall.
Now when I view the app, I see
Solar Generation 41.2kwh
home usage as being 28.9 kwh
Net Usage being -10.4kwh
So the net usage matches my electricity bill.
My question is the home Usage calculated after pulling from the String Inverter System because the number doesn't add up since my old system should generated 30-40ish and even calculating at the low end, say 60 kwh - 28.9kwh, I should get over -30kwh. Should I be worried about this or is the home usage actually a higher number that the app wouldn't know because of the two system.
