Hi everyone!
First setup and before I button everything down I was wondering what options I have. Currently 12 x 100w (cheap) flex panels with 2 viltron 100/50 mppts going into a 12v lithium battery bank. Ive posted a full sun power image below for what I was getting. I have 2 main questions I was hoping I could get some help with.
I have room for an extra 2 panels. One would fit fine at the rear and another just barley under the starlink dish in the front. It would be blocked by shade for some angles but open for most of the day. The main issue I see here that I didn't account for is the angle of the rounded roof.
The sides of the bus are rounded to the left and the right sides. With some help from a forum member I went with 3s2p but After a little testing I see the power levels with the different angles. I was thinking about going to 2s3p and adding fuses so that I could make left, center and right strings. It would also allow me to add the 2 additional panels.
1. Being that one of the additional panels will be in the shade 30% of the time I understand that these two panes will not produce during that time. Is it possible to run the shaded panel individually? Ive been trying to keep the voltages the same but just wanted to check and see if there was a trick. If that was possible I could add one spare to the front controller and one spare to the back controller balancing the load. Ideally 7 panels on the front controller and 7 panels on the back controller.
2. If I do make left, center and right strings on the same controller will this hurt anything? Parking headed north the left string would be low sun, the center would be full and the right would be full. So will the left string have any issues during this time or just produce less?
Any help or possible ideas would be greatly appreciated!
