Witch the tutorial videos and set a custom TOU
Took a while for me to figure out but on the very last step of setting up a custom TOU rate, you can choose exactly how the system behaves for each time frame. In my case, because we don't have built-in automation to account for cloudy weather, I wanted to mostly stay in self-consume mode but switch to charge battery from solar for a couple of hours to ensure its topped up to cover peak utility hours.
