Panels calculation

[Kevcando]

Hey guys need some help with how many panels I can hook up to this Mpp 5048. I have 25, 250 watt panels and it looks like I can do 3strings 4 parallel on each input and still be safe. Is this correct ?

Voc 37.6 x 3 = 112V, safely within 145V for you to not have to worry about low temperatures.
Vmp 30.3 x 3 = 90.9V, within MPPT voltage range so MPP will be able to get maximum power from the arrays
3000W well below each MPPT input's 4000W capability
Imp 8.27A x 4 = 33.08A, well within the 80A limit of the MPPT PV inputs

Looks good to me.

It isl ike me drifting in the Atlantic ocean....
I am planning the same inverter you would like ect....
I hope the link would help you to get a idea.
I think 8-10 panels are good for one inverter, again i am drifting in the Atlantic.....
