Can anyone help me, I want to simulate polystring configurations with the following build ABB trio 27,6 MPPT 1 string 1 compounded of 2 strings is series on two adjacent roofs but equal slope etc. these are 7 and 10 panels trina solar 330Wp. MPPT1 string 2 17 panels parallel to string 1 MPPT2 two strings of 17 panels in parallel. When I use polystring I can't get the partial strings that are in series in parallel with the other string. Anyone knows how to do this? thanks in advance Paul
