I recognize this is an old post but I’m new on here and can’t start my own thread. I’m an e-27 customer with one powerwall and 9.6 kw. I’d prefer the powerwall to only come on when my supply from the grid hits 3 kw or higher due to demand charges. My system got turned on a few days ago. It seems like the powerwall does great at preventing grid use until it runs out of juice and then for 30 minutes I use enough to hit the >5kw fee/usage charge. If I could get the powerwall to help me out with anything over 3 kw demand it would prevent that charge and last longer. Anyway I know this is poorly explained but I’m hoping there is a trick.
