Hi all, first post. Thanks for having me
I'm building a system on my travel trailer with 3x 200watt Newpowa panels mounted permanently to the roof in parallel, a 60a Renogy Rover controller, and a 200ah Ampere Time LiFePo4 battery. My question relates to wire gauge. The Current at Pmax (Imp) of the panels is 10.75a. Given the parallel arrangement, at 100% efficiency (won't happen) I'd theoretically have 32.25a traversing the wiring to the controller. If I need to make a run of say, 20', what gauge wire would you recommend? The trailer is already prewired for roof solar but I'm guessing it's small gauge and I'll need to use it to pull new wiring. Based on amperage charts online it looks like 6 -8 awg is recommended for this. Is that correct?
Second (related) question: I purchased a 3 into 1 Y connector to connect the panels on the roof. After purchasing it, I found that the "1" lead combining the 3 leads from the panels is 10 awg. Being that this would be the "start" of combined amperage run to the controller, shouldn't I have 6-8 awg coming off of the 3 combined leads? I'm not seeing any Y connectors on the market with a higher gauge than 10.
Thanks!
