For residential installations, there are off-the-shelf solutions that encompass a variety of potential configurations, saving the time and extra expense involved with custom solutions.

Combiner box

It really depends on how you wire the converter box... But the standard wiring is, if you have two (or more) "strings of panels", when you connect them to the combiner box, those strings are connected in parallel, so your combined output would be 150 Volts @ 36 Amps (2 parallel connections of 150 volts @ 18 amp strings).

Calculating pv panel combination values at the charge

Assuming that the 2 strings enter a combiner box before entering the charge controller, are all of the conductors entering the combiner box considered to be in parallel when they leave the combiner box and enter the controller? Example: 2 panels wired in series (10.18/45.4V + 10.18/45.4V) = 10.18A/90.8V when each string enters the combiner box.
