0 Solidox Posted March 13, 2023 Share Posted March 13, 2023 This is a great resource, knowing energey loss every step of the build is crucial in accouting for power reserves. Also shows the importance of keeping lower voltage wires shorter and larger gauge. Electrical fires are no joke, especially when you are confined in a small space such as an RV or Van.

0 Kip McMillan Posted March 13, 2023 Author Share Posted March 13, 2023 One important thing to note is when calculating length of wire, you need to figure length both ways. Return trip as some put it. Quote Link to comment Share on other sites More sharing options...
0 Solidox Posted March 14, 2023 Share Posted March 14, 2023 Are you refering to adding length of positive and negative together to get total distance? Quote Link to comment Share on other sites More sharing options...
0 Kip McMillan Posted March 14, 2023 Author Share Posted March 14, 2023 Figure per wire. 15 feet from panel to controller. And back. 30 ft. Total length 1 Quote Link to comment Share on other sites More sharing options...
0 Solidox Posted March 14, 2023 Share Posted March 14, 2023 Ah, good to know, I was only accounting one way. Running 3 panels in parallel so with movement shade wont effect me that much. Quote Link to comment Share on other sites More sharing options...
0 Kip McMillan Posted March 14, 2023 Author Share Posted March 14, 2023 Nice thing about Newapower panels is that their leads are 10awg. Renogy uses 12 and 14awg. 1 Quote Link to comment Share on other sites More sharing options...
0 Solidox Posted March 14, 2023 Share Posted March 14, 2023 Didnt know that, but great to learn. I was planning on using 10awg anyways for semi futureproofing. Now just gotta find out how i'm gonna route it. Quote Link to comment Share on other sites More sharing options...
0 Kip McMillan Posted March 14, 2023 Author Share Posted March 14, 2023 I'm going to go 2s/2p with 10but from the junction box on the roof to the controller I'm using 8awg in case I add more panels later. Quote Link to comment Share on other sites More sharing options...
