There is “no perfect way”.
This data sheet will lay out some the data for you to make your decision with the equipment (solar panels & mppts) that you currently have.
PV MPPT
Watt = 365 150/60
VOC = 48.3
IscA = 9.7
VmppV = 39.88
ImppA = 9.17
Series / Parallel =% capacity of MPPT
2 / 2 = 85%
2 / 3 = 127%
1 / 3 = 64%
1 / 4 = 85%
1 / 5 = 106%
Series
Increase Voltage
Amps Stay Same
Panels connect to each other in Daisy Chain Fashion
~Higher output under normal circumstance
Parallel
Amps Increase
Voltage Stays the same
Performs Better When part of the solar array is shaded or broken.
*need combiners
Increase the number of Inline Fuses needed.
If I thought I’d back the back of bus in shade or one side in the shade then I would do that section in parallel
If going 2/3 & 1/4.
Get
3 ) 30 a inline
2 ) 2:1 Y branch pair
1 ) 3:1 Y branch pair
1) MRBF Terminal
1) MRBF Fuse 300
Ultimately you will want to upgrade the battery cable. to Copper preferably the Tinned Copper I sell.
