EG4 6000ex unexpected grid surge

[wildbillpdx]

I'm running an EG4 6000ex with three EG4 LifePower4 batteries (48v). The batteries are fully charged and I'm getting some solar production. The inverter is running in Solar/Battery/Utility mode so power should come from solar then batteries. But twice today there was a usage spike that resulted in a grid feed that shouldn't have taken place. Looking for ideas.

I'm betting you have overload bypass enabled.
I forget the setting #

Yes...I think I do. But is the data showing an overload? It didn't seem to be.

No, no overload, well there could be a few millisecond overload depending on what you are trying to start.
I'd say it's a quirk of the LVX6048, TP6048, EG4 6000EX, maybe more.
I had noticed graphs very similar to yours when my well pump would kick on, I disabled overload bypass and the problem went away.
