Growatt SPF 3000TL LVM 60A max charge

[GSXR1000]

So what it is doing is charging maximum of 60A. so let's say I have no solar I charge with 60 amps from the grid... but when I add solar let's say 700w. my grid charge will go down to 30A and get 30A from solar... I have max charge set to 140A

Is the 3000tl actually capable of 140a of charging?

Just checked.
80a maximum charging capacity.
Double check the settings. It appears that your setting is 60a.

Check the settings on the units screen.
To make sure that it matches Solar Assistant.

Seems very odd.
Have you tried changing the settings from the units screen, instead of from Solar Assistant?

yes.

Sounds like a firmware issue. If it won't take the settings.
Unless the battery won't take any more charge.

Hopefully it's that simple.
Good luck, and please let us know if that fixes it.
