Voltage calcs clarification?
Here's the system: 36 Sharp 208s (3 in series, 12 in parallel making up three sub arrays), a preassembled power center with 3 MX60s and 2 FX3648s, and 8 Surrette 530s in series. The specs for the modules are: Voc 36.3, Vpm 28.71, Isc 7.99A, Ipm 7.25A. Each string yields 108.9 Voc and 7.99A, each sub array at the combiner box would be 108.9Voc, and 32A. There are two PSPV combiner boxes, one is 60' and the other 40' from the dc disconnect / power center.
When determining the voltage drop between the PSPV and the power center things seem a bit odd: 32x125%x125%=50A at 108.9V, yet all the tables are for 12, 24, or 48V... I've got to be missing something?
