System SOC jumps to 100 at night

Use case is offgrid solar. WM4 in use for years.

This is seems to have started with upgrade to Toolkit3 and newest firmware.

Looking at other threads, some people have reverted to older toolkits/firmware and that has solved the problem.

Other than reveret, is there a fix for this?

Hi jtvt,

Do you have your system provisioned on bmi.batrium.com? See here if not:
How to use Web Provisioning / Remote Access | Batrium Knowledge / Wiki

If you have it provisioned, please DM me your serial number so I can take a look at data over time once it’s got one of these events in there.
