Hello and thanks in advance for your time! Our Ford Transit has 4x200W "12v" Rich Solar Panels mounted on the roof. They are currently wired in 4s (series). Would it be advantageous to switch the wiring to 2s2p (series-parallel) configuration?
Concerns of partial shading come from the MaxxAir fan being near the front panel which could shade with sun coming from the front of the van, as well as it being a campervan and may not always be easiest to avoid partial shading positioning.
A.) Specs for the (4) 200 watt RICH solar panels are:
Charge Voltage:14.6V
C.) 60A Solar Charge Controller
Max. PV Input Voltage: 150 VDC (25°C), 140VDC (-25°C)
Wired in 2s2p, then the panels are at 40.8V max, and 19.6A.
Wired in 4s, 81.6V max, and 9.8A.
Thanks for any help/comments on the setup.
Also, we are installing a 12v 2000W Samlex PSW inverter as well, and the 12 circuit Blue Sea Fuse Block as the rest of our electrical components.
