this is what they are; I don't understand why the flow arrow is pointing back at the panels.
how would a meter show a diode? mine has a fuse inside, could it be both. their diagram shows one on the positive and one on the negative. the arrow on the second one is probably pointing the opposite way, but right now , it's too cold outside for me to check it .
Eg:
the online picture doesn't show the arrow. I didn't see a diode inside only a fuse. I wonder if the arrow is to indicate which line they want you to put it on. I only want one on the red cable. if it is only a fuse, it should not matter what direction it faces.
Not sure what this pic means. I don't see anything inside that looks like a diode Correct
If you have a meter, I would just check it to be sure.
It tested as a fuse, but I haven't used it yet. When the panels were hooked up, the inverter panel input dropped from 280v to zero. The new panels are reading 85v at the breaker and where they connect to the splitter. When I tried shutting down the original panels and just using the new panels, the inverter reads zero volts. I even switched splitters and nothing. Here is one of my crude diagrams. What should I try next?
I wasn't thinking in terms of strings. I see your point. Probably should put them in series with the other 8.
Are they facing the same direction and angle?
the EG4 says 500V max, these all would only do 450V max. They both face south, but these are flat and the others are at about 25 degrees. The new ones are bifacial too and will get some light from below.
Not the best setup. But a lot better than 8 and 2.
