Not sure how to wire

[22blaze22]

Need help not sure how to hook up have a 3000 48v growatt have 4 more panels right now I'm only using 6 series or parallel about 1200watts and have a combiner box

So you have a total of 10 panels?
5s2p

You might be close to the limit in cold temperatures with 6s. Did you calculate the max Voc for your record cold temp? Search for the Midnite calculator if you haven't.

With those panels you can go 5s2p with a branch connector no combiner box needed

Already have combiner anyway to just use my 6 panels

Already have combiner anyway to just use my 6 panels maybe 3 in series into combiner should be around 111 voc will that work ? And I think about 47.4 Amps is that right for my growatt? Tks

You don't need to combiner you can run 5s2p and use a branch connector you want higher volts and lower amps your max is 18 on the pv

Since you already have the combiner you can still use it, it won't hurt anything.
Bring each 5s string to a fuse then send them to a breaker which feeds the AIO.
I ran 2 9s strings through mine I DIYd.
Old pic for the heck of it.

Will what I said work? I've only got 6 mounted have to build another ground mount to use more

You have to run the panels in series 5s ideal and you could run another 5s to get the watts you cannot run them in parallel of more than 2 or you will go over your 18 amp limit
