Hi Paul, on page 169 of the PDF help document, it is said that “SAM can only model systems with one type of module, and one type of
inverter. You cannot use sub-arrays to model a system that combines different types of modules or inverters.”
I am busy with one commercial installation where the previous PV modules are “no longer available” and for the extension of the
system, I must use PV modules which are currently available. These PV modules are of higher ratings and from a different manufacturer. Secondly, the inverters, although from the same manufacturer, are of different ratings.
So, if I understand it correctly, I cannot use SAM for this nor any other installations where I may have to use different sized inverters
per sub-array?
