My 11 KW system just got installed in FL. The two-way meter is not in yet, but I was advised to run the system to charge the two power walls. I am also experimenting with the grid power turned off to get an idea of how well it can backup the house during an outage.
My big question at the moment is how it splits power from the panels to the walls. When I am off grid, according to the app, it is frequently turning off the panels and running the house on the power walls. The power walls are at 85%. I would really like to see it charging rather than expending them. It happens in both the backup and the self-powered mode and with the sun out or behind a cloud. I don't see a way to control it. I realize that if the panels are not producing enough to run the house, it will pull with the power wall and I have seen that happen with energy still flowing from the panels. What I am seeing, however, is the panels off for up to five minutes at a time.
Also, there is supposed to be a storm mode available. It is not on my menu. My understanding it that it would top off the power walls with grid power if a storm is forecast. Did this feature go away or was it eliminated to maintain the tax credit?
Thanks for any help.
