SunPower system power recycles at almost the same time each day
Hello Reddit SunPower Community,
My (paid by cash) SunPower system consists of a Hub+ (PVS6), Two SunVault Batteries, and 30+ Panels.
I noticed that the lights on my SunPower Batteries were cycling through a F.72 fault multiple times each day, and one of these cycles happens almost every day at around 5:30 PM Pacific.
Recorded a video a few days back and here is what I noticed:
05:20 PM: System operating as normal with my home being powered by Panels and the Batteries.
05:21 PM: Only two lights on both SunVault outer displays were on - the internet connectivity and grid connectivity. Opened up the main SunVault cabinet and notice an F.72 Error on the inside screen, AC1 LED was off, AC2 LED was blinking green, and Error LED was solid red.
05:37 PM: The inside display changed to OFF, all lights went blank, blinked on, went blank again, and the system then began to power on. I could hear an audible click from the two SunVault batteries.
05:39 PM: The system returned to normal with only the AC2 LED now a steady Green.
Reached out and received two different opinions from people familiar with SunPower systems – they both logged in remotely to review my system. One suggested that the system was working normally and that I should not make any changes (something about the power cycles being attributed to trickle-charging of the batteries). The other suggested that there seemed to be issues with the system communicating with SunStrong servers (given that this happens almost every evening at about 5:30 PM) and that perhaps I should consider blocking the system from communicating with the SunStrong servers.
Has anyone encountered behavior like this from their SunPower system? I sure could use the collective guidance from this community to help identifying the underlying cause and a possible solution.
Thank you all.
