small house in the city off grid system

[gloves12]

Hi! This looked like a lot of fun, I'm currently powering a microwave, a desktop computer, and some lights. The auto-transfer switch means I can keep the batteries between 90% and 40-ish% charged, then swap over to city power, hopefully extending my battery life. The romex runs to my kitchen and office, both have a "solar outlet" wired up. Panel wires come in the same penetration as the AC pipes; just poked a hole in the caulking, pushed the wires throught, and sealed it back up ?

Thanks for taking a look!
