So it would seem I’m missing a panels worth of power. Thanks guys, time to get a amp meter out.

Sorry, newbie. does 3s mean 3 solar panels? I have 4 12v solar panels on the roof, so does that mean one of the 4 has a faulty connection to the system? They are wired in the manner Will dictates in his 400w classic build.

So Will’s excellent instructions, book and videos gave me the info to put together the classic 400 on my food truck. The goal is to forgo the geni on sunny days. I achieved my goal yesterday and ran fridge and electronics on solar all day! What I don’t know is how to understand if the data...
