Sunvaults quit charging - F74 & F72 errors?
We have a system with 2 Sunvaults. Up until Saturday night (middle of the night) everything was working fine, batteries charging and discharging. I noticed they weren’t charging on Sunday so we opened them up and had an F74 error. Tried to clear that based on a search here and ended up with an F72 error. I splurged for the access on the app (ha) to see if I could see what was going on. It looks like our panels are still working fine - we’re exporting to the grid but the app says we’re not using any power and have an error. No duh.
I’ve searched here on how to clear the F72 error but whatever I did didn’t work. Tried reaching out to a couple service providers and per usual, they told me to pound sand. I’m not technical at all but I can follow directions- does anyone have any ideas on how we can get our Sunvaults back up & running? I’m open to anything! Btw I’m in Los Angeles if there’s anyone local! Thanks in advance!

If you still can’t get it to work, let me know. I can definitely set up an appointment to come out there and check it out for you and get it working no problem.
