I will additionally call Solark Tech & see what they have to contribute.
Thanks all for the real world first!

This is interesting, set all aside temps, how its constructed, the power
cycle is what changed it. Sounds like the inverter(s) were stuck in a
finish charge, this may be a programming issue, is it available on line to
watch remotely, has it done that again, next day?
Fun times programming
On Sun,
That is not my experience with all of the xanbus model AES. Maybe the
ones from 2018? All of the others will shut down the contactor and you
will lose inverter to protect from charging at temps below 32F. There
will be plenty of warnings and a fault event into the Conext Cloud
devices or
Dana,
Sounds like potentially the same issue I've been dealing with in a new
Sol-Ark 15 paired with Fortress eVault Maxs. Apparently, Sol-Ark did a
recent firmware update that caused erratic closed loop communication
between the inverter and batteries. I don't know if the Sol-Ark firmware

If they are the AES 48-6650 batteries I think they do *not* have low
temperature mode, and will be damaged if they are charged while they are
below freezing. The AES 48-3000 I think *do* have a low temperature mode
and would prevent charging if they are below freezing.

Hi Dana,
What type of batteries? What battery mode?
If you have Lithium batteries with communication enabled, there are certain
modes that the BMS is running the charging show. I've seen the Sol-Ark
throttle back charge as instructed by the BMS under these circumstances.
A quick check of this
Hi Dana,
If the battery is in closed loop with the inverter and the battery is cold,
it might be limiting charge due to cold temps.
Best,

Hey Now All Wise ones!
An of gird client emailed yesterday that his Solark had been accepting only
350 watts of a 4KW input from the array. The modules are Q-cell 325 watt 2
strings of 7 modules.
