Sometimes I lower my amps so that I can charge during the day and use my solar without tapping into the grid or my Powerwalls. Last night, I forgot and lowered the amps before plugging in so it started charging at 48 amps at 9:30 this morning. I had to go out and change it to 32 amps so that my solar could handle it entirely. As the day goes on, I sometimes bump up the amps to 40 or 48. It will be nice when our cars are able to communicate with the gateway and adjust the amps automatically.
