I am searching for a new junction box. Some have double the amount of diodes. Does it matter? do the amount of diodes correspond to the wattage of the panel?
I have a 175W 24V panel missing the junction box. I tried a box rated from 200W -300W. It has 6 diodes. I only got 11.7V. When I tested the busbars before putting the junction box on I was getting 32.7V.
Can someone please explain how the diodes and junction box work, or which way the current flows (diagram). Sometimes it is better to understand how it works than be told how to do it.
Thanks.
