If so, and the shadow is falling on both panels, you might be getting less than 50% power, possibly as low as 25%.
No, it's not. I'm putting one of these on? Can you see an issue.

And No i'm not drawing you a diagram for you to then pick on my line thickness or shade or some other pedantic insignificant issue. 'Parallel' are all plus together and all neg's together. The other option is 'in series' which would then however bump my volts. My panels were sold to be added in series, hence I needed to swap a connection to put join them.. Is this clear for you? Can I make simplify for you any more than that?

It's not that you needed to simplify it, it's merely that you needed to explain that you chopped up a connector because you couldn't wait another day. The connector genders are based on pos or neg terminals, not on whether you decide to connect them in parallel or series. Panels designed for grid-tie systems are generally connected in a series string, but the only difference is they generally can withstand a higher system voltage, the connectors are still the same as any other panel.

Keep in mind, you're the one who came on here asking for help with the most BASIC of electrical connections, so excuse me if I'm not quite sure of the depth of your ignorance. I'll stop wasting my time trying to help you out.

YOU may think I'm being pedantic, but as a former Navy instructor and technician, the details make all of the difference in the world, even if you don't think it matters. You've already seen what sloppy soldering can do for you.

Absolutely. The issue is very clear.

That depends. What kind of anchor are you using?

Solar Panel Wiring Question

So another question. My Morningstar mppt controller is rated to 45 amps. What size fuse should I put in? I bought a 50 amp switch/breaker surface mount blue sea is this ok? The manual Did not say.

Thanks!

It depends on the wire gauge you are using between the controller and the battery bank. The larger the wire the larger the fuse can be. Larger fuses have less voltage drop than smaller fuses so larger is better.

It's 8 AWG. Looks like the 50 amp is about right then thanks.
