Utility company visited me for exporting from my solar Off-grid growatt LVM-ES SPF 3000TL

If you set it low enough, it would essentially just float / supply voltage whenever the batteries dip low enough. Technically it would be "charging", but not very "charging", "charging".

It's basically just a power supply.

I do
But I just use it to float the battery at 48v (just covering loads), until the sun comes back.

same here, I set to 43v (tesla model S, 36v is empty), and just run loads, waiting for the real battery chargers to come alive again with the sun
since low battery "usually" occurs at 5am in the winter, not much of a load in the house then. Have not had a low battery event since early March

Chargeverters are cool

I probably post this pic too much, but it explains alot
