I need some advice on using SAE connectors with a portable panel set up on a cargo trailer. We need a 100 amp hr Lifepo4 battery and 120 watts of panel to run a 1.7 cu.ft. dorm fridge and the lights in the trailer. I have access to Some SolarTech 45 watt panels that have are small and lightweight. I'm thinking hat 3 in parallel will get us the required wattage, and because they are aluminum frame panels, not fabric mounted panels, 24/7/365 exposure will not be an issue. What gauge wire do I need for a 25 foot run? I have a couple of sets of 12ga cables & ports, but I've received conflicting info as to whether 12ga is large enough. I've attached the panel specs. We'll be using an Epever 20 amp SCC. Thank you for any help you can give.
