Planning a future installation in my travel trailer. Thinking 4x 100watt panels, 2x 100ah lithium batteries, 2000 watt inverter/charger.
I'm confused about whether I need an auto transfer switch. If I'm plugged into 30A shore power, I wouldn't turn on the inverter. If I turn on the inverter, it's because I'm not connected to shore power. I'm trying to imagine how I would ever wind up with the inverter on AND shore power connected and possibly overload my AC panel. Even if that's a real possibility/risk, wouldn't a manual transfer switch work just as well for less money?
What am I missing?
