I know in the AC180 manual there is an error code E086 (Charging temperature too low), but I just wanted to ensure that if the battery is below 32 degrees fahrenheit, it will not allow a connected solar panel to damage the battery?
Furthermore, is there any downside to leaving the solar panel connected to the battery long-term once the battery is at 100%?
Thanks in advance for your help.

The error E086 indicates insufficient temperature for charging. The machine cannot charge below 0 degrees Celsius, but it won’t damage the battery. This error setting is in place specifically to prevent battery damage. Currently, BLUETTI models do not have the " freeze protection from solar charging damage" you mentioned.
I’m confused, if the unit cannot accept a charge below freezing then wouldn’t it be protected from solar panels damaging the battery below freezing?
