How to calculate how many PV panels I need for my solax system?

s1. N1= Max Powe(INV)/power(single solax panel)

S2. In series conditon:N2=Max MPPT input voltage(INV)/VOC(single panel), select the smaller one(N1, N2) In parallel conditon:N3=Max input current(INV)/Isc(single panel), select the smaller one(N1, N3)
