When charging my Bluettis with my inverter, the inverter starts beeping and then shuts down. I have a Victron shunt attached to my two Everlast 100ah size 27 AGM batteries. They are both less than two years old.

It used to, meaning maybe a week ago, would charge it up just fine. The only change is that I only have 200w of panels right now as my other 200w are in need of a cable.

Yes, when I’m running the engine this all works just fine. Is it because I don’t have enough incoming to keep it high enough? Sometimes the shunt will show 94% before it happens, although more consistently now at 97%.

I’m okay with all of this, but would like to be able to lower the threshold for when it happens. The techs from the inverter company say it’s working as expected:

Hello, according to the video you sent, the inverter is not broken; this is a normal low-voltage protection. During the final stage of charging the energy storage power supply, it will limit excessive current input to protect the energy storage battery from overcharging, which will trigger the inverter’s protection. This is a normal phenomenon.

I’m hoping they misspoke because that answer makes absolutely no sense at all to me. Protect the battery from overcharging? This happens regardless of what % the Bluetti is showing, and as you can see it’s nowhere near overcharging. I’m thinking they mean the source batteries from being drained? But even then, at 97% they are nowhere near being drained.

Here’s a series of shots I took this morning when troubleshooting:
