AC doesn’t work after lithium/inverter install

Hi all, I just recently finished a full lithium/solar/inverter setup in my travel trailer. it is a 3000w pure sine wave inverter and 510AH of lithium batteries. I also installed a new lithium charger...

I also wondered why run the AC on an inverter where the draw is around 140A DC. Less than 3 hours AC run time then batteries need charging.

Running AC's on batteries is best done with a 48V DC system where the amp draw will be 1/4 of a 12V system IMHO. Of course this means 48V inverter, 48V charger and a 48V to 12V converter for the house. But your batteries aren't designed for serial connection.
