Hey guys,
I’m new to the forum, brand new to solar and I have a number of questions about my RV solar install. I would appreciate any advice, and thank you all in advance.
I just mounted 12 100-watt Renogy compact solar panels on my 23 foot Grand Design travel trailer. I want to wire them in series-parallel, (2 panels per series) so 6 arrays of 2 panels paralleled to a junction box. So I will have 6 positives and 6 negatives coming into the box (through cable glands). This will be a simple roof mounted waterproof junction box with a positive bus bar and a negative bus bar.
I plan to connect all six positive wires (10AWG) to a positive bus bar, and connect all 6 negative wires (10AWG) to a separate bus bar. Then run 1 positive and 1 negative wire off the bus bars (4 or 6AWG) to the charge controller.
I will have an in-line fuse on all 6 positive wires from the panels to the box, and a breaker on the positive lead going to the charge controller.
—Do you see anything wrong with doing it this way, am I missing anything?
—Am I missing anything.
—Is there any potential for back-feeding between the panels doing it this way? Do Renogy panels have diodes to protect from this?
—With 1200 total watts, I’m looking at a Victron 150/100 charge controller. Will it handle 1200 watts Solar?
Thank again for any advice or tips.
