MPP Solar turning off MPPT for rest of day fix?

[Guda]

Twice now I've turned on my electric heat on sunny days just to find one MPP Solar AIO has turned off its MPPT & keeps it off until the next morning. This sucks. The system will run the battery to nada & keep the MPPT off on 1 unit. Any way to fix this in settings? I've got 2x 3k AIO. 1st time it happened it turned off SP2, 2nd SP1.

This has been described at least a few times. Hard resets seem to correct it to varying degrees.

I'd check with your vendor for a firmware update.

Its pretty weird. I turned off all big loads, came in to post, it fixed itself this time.

I did a firmware update to my original AIO now both are current. All before this issue.
