Genny shuts off when SOC reaches 88%

Hi guys,

I upgraded the firmware and all went well. Before upgrading the firmware I noticed the charge voltage jump to over 30 volts occasionally on my 24v/230ah battery which obviously is bad, so after the firmware upgrade I set an overvoltage alarm and lynx shutdown to 29.2 volts. Sure enough as you see in the chart, it just jumped up to over 30v and the lynx shut down as expected.

What’s the deal? Why would the voltage jump so high? When the lynx shut down so did my genny a min or so later.
