I had 4 AGM group 27 for a total of 368Amp.
I have added 3 more batteries for a total of 7 x 92 Amps or 644Amps
Do I need to change the Total capacity somewhere?
My total Capacity on the app shows 400 (Ah) on the Battery Status meter?
If so where is this being changed, I looked everywhere
AGM batteries in parallel is a tough cookie. Their internal resistance is so low, that the cable interconnects are not going to help share the load. So the best battery is going to contribute most of the work till it's no longer the best, and another battery takes over.
Overall. massive parallel banks tend to not last as long as series banks for the same batteries.
Adding new batteries to an old bank, usually just rapidly ages the new ones til they are a bad as the old ones.
If you must parallel batteries, this website

has a good tutorial on how and why (with all the math) so you can get the most life out of your expensive batteries

If you are using the Local Status App then you go to Config / Advanced / Battery Status Meter and you will see capacity and you can change it there.
Also I agree with what Mike said above.

I always agree with Larry ;D ;D ;D

I agree with Kyle here...
