Amps not adding up: 2 panels in parallel
Happy Fourth of July!
tl:dr - How come my amps aren't around 18A with two 9.18A panels?
Is it the panels or cables? - I wired the two panels together in parallel. We tested them with a volt-meter. They produced the proper volts (around 18 volts), but amps were NOT added together as they should be with two panels. We only got around 8 amps total when testing the two panels in Parallel.
We then tested wiring them together in series, it produced 37 volts (normal), but for amps, it produced 18 amps, double the number of expected amps, which doesn't make sense as amps aren't multiplied in series wiring.
Both panels, when tested individually, produced the proper readings. When we wired to the smart controller, it only reads 8 amps too when two panels were wired in parallel under direct sun.
Maybe it's the Smart Controller? - My smart controller says 24V for "Rate.Vol (image below)?" What does that mean? Shouldn't it be 12V since my panels are 12V?
Thank you! I will drive out to whomever can help with my converted van and shower you in cookies and beer!
