Hello,
For the second time in its life, my multiplus-II is not charging anymore the battery on my ESS system:
Everything was ok until 6th July, at which time it slowly stopped to use/charge battery.
I don't have change or touch anything in the configuration or installation, the installation was working without problem for months.
Also I had the same issue last year, at same period, during summer, and workarounded it by turning OFF, turning ON the multiplus (physically, as restarting from console not helping), which I will do again (except if someone needs me to do something to investigate/fix the issue).
I think it is a bug in the multiplus software and the way it manage battery.
Regards. M.
