Looks like you have set Winter Conditioning to ON and you battery must be getting cold.
Maybe their software is not smart enough to put your settings back to what they were after they have intervened (untested before release?)

If you use the second time slot for your timed charge rather than the first it doesn't get over written by the battery conditioning. Pretty sure this was discussed last year when conditioning was introduced.

if it was identified last year, why oh why have they not corrected it? rhetorical question
thanks for the info

yes and yes.
Maybe their software is not smart enough.
(untested before release?) escape. why no bug fixes.

The inverters (particularly the older ones) have very little memory storage so things like “remember what the settings were beforehand” is probably not possible. And even if it was I wouldn’t think it would be a priority to be changed and tested across all the different firmware versions; there’s more priority for the dev team to work on.

Winter battery conditioning uses slot 1 when it activates so as @PaDav6 says, use slot 2 for your charging.

I received a low temperature alert from one of my batteries yesterday:

A reminder to keep the garage door closed in winter and not leave it open all day.

If the batteries get too cold they will slow down the charging rate
