Adding a second lot of panels
Wow, Thanks for all the comments,
I can’t see another input for panels on my pip5048 So I guess it only has one mppt,
This is my setup

As you can see I also have a pcm60x to charge the batteries,
I wanted to fit another lot of panels in with the first lot of panels on the only input (the yellow line in pic one)
The panels I have are very close to the other panels I’m using on the pip5048
I realise that there won’t be must gain in the winter month but where my panels are it gets shaded around 16:00 but the front of my house still has sun, I want to get ther last 3-4 hours of sun in the West,
What I’m trying to say is, when the West panels are fitted and working (16:00 onwards) my south panels are in the shade, so as long as when I first plug the second (West) lot in, my system doesn’t drop to the lowest it see’s (the west side panels) it should be ok,
I think I might need a few back feed diodes though.

I looked up a pip5048 this is what I found.

Based on this, I would suggest you buy a 2nd pip5048 and hook up the 2nd PV Array to it,  hook this 2nd one to the existing battery bank, and perhaps ignore the 230v output as presumably you are happy with the exiting AC wiring on the 1st one.   This second one will thing take in the power from the 2nd PV array and charge the battery bank (for use by the 1st one to generate AC power).

Full disclosure - I use mutliple Midnite Classics to same battery just fine...   but I'm not an MPP Solar (equipement/settings) expert.   So please confirm this suggestion elsewhere before spending $$.
