solar & battery in Mountain House — FAQ
Do I need a panel upgrade for a battery in Mountain House?+
Often yes — battery and solar interconnections must meet NEC 705.12 (the 120% rule). We check your busbar rating and, if needed, upgrade to a solar-ready 200A panel so it's done once, correctly.
Can you add backup without full solar?+
Yes. A Tesla Powerwall or battery can back up your essential circuits with or without solar. We size it around your must-run loads — fridge, Wi-Fi, medical, well pump.
