Alright...now that I've figured out my EG4 18kpv install (still awaiting delivery), I'm thinking about the next project...which is 2 of the 4 panel Signature Solar Brightmounts thrown in my side yard, with some sort of bifacial setup of 8 panels. They will be facing the same direction and roughly in the same area, but will experience some shading at different times in the AM/PM as the sun comes over the trees.
Right now the Canadian Solar 400w bifacial split cell panels are in the lead, but that can change. I just cannot exceed 44inches wide on the panels.
Their operating voltage is ~39v. So 4 in series will be around 155v.
The spec sheet on the 18kpv has the following for the DC inputs, which I admit to not fully understanding:
Full Power MPPT Voltage Range 230–500V
DC Nominal MPPT Tracker DC Voltage 360V
DC Nominal DC Voltage Range 100–600 V
DCMPP Operating Voltage Range 120–500 VDC
1) So is the 150v a bit low and I am better off running them in series?
2) Or will paralleling them by using the 1st PV input (the parallel input ) in the 18kpv handle this for me?
3) Will my shading issues + 8s potentially negate the benefit (if there is any...see question #2) and I'm better off keeping 4s2p?
Early in my research but any input is appreciated!
