I am using PGE EV2-A. Can I charge my powerwalls during the off peak times? I see that happens when we get a Storm Watch warning and the powerwalls fill up to 100% in anticipation of a power outage. However, when we have less sunlight or higher air conditioning needs during the peak and shoulder times, my powerwalls get depleted (to my 20%) reserve before the end of that time. It would make more sense to charge the powerwalls during the off peak times (after midnight) and if the powerwalls are filled to 100%, then if there is extra solar power available, the grid can be charged. The powerwalls can then be used during the peak and shoulder times and not run out so early. Basically that effectively partly arbitrages the grid power. Thanks.
