In San Diego we have a very aggressive utility that does not like solar taking any of its profits (although the solar has stabilized their grid.) They have recently implemented a winter peak time of 5pm-9pm that will become a permanent peak time in 2022. That means that they are taking in PV generated power at a lower cost during the day and selling it back at a higher rate after the sun goes down. So so lame of them. Can the PW be programmed to fill during the day and discharge from 5-9pm? This would solve my problem, but I don't know if it is possible. Just an FYI, this is a beta test for other markets....so that sucks for anyone that does not have a battery. It helps to have a PW now, but if I could have it hold at 100% (charged by PV) at say 3pm, and wait so I am supplementing grid power until 5pm and use battery power at that point, I would be in much better shape. In the depth of winter my solar starts dropping off around 3pm so the battery kicks in and by 5pm it is at 70% or so and I only get to 7pm before the battery is done and I am back on grid power. I hope I am making sense. Any guidance or feedback would be greatly appreciated. I understand my install and I have all the specifics, I also have the details on the new "Time of Use" program being implemented by my utility if that helps in any way. Thank you for your time and attention in advance.
