Specs of my 4x Renogy 12v 100W Panels:
Short-Circuit Current (Isc): 5.21A
Maximum Series Fuse Rating: 15A
Getting conflicting info and can't seem to find a reliable source of info on this. Want to make sure I get this done properly to keep everything safe. Looking to connect these 4 panels in parallel using this 4 to 1 branch adapter www.amazon.com/dp/B08NV5PB9X and want to make sure they are fused properly:
This site says to do sum of Short Circuit Current for all Panels. If sum is greater than Max Fuse Rating, then fuse must be Max Fuse Rating. In my case, using his guidance, this gives me a fuse size of 15A.
HOWEVER...
This says to do Sum of Amps * 1.25% to get proper amp fuse size. Doing the math ((5.21 * 4) 1.25), this gives me 26, which would require a fuse size of 30Amps if we round up.
Which calculation is accurate to make sure that I'm safe? Seems like there's a lot of different opinions on how to calculate this online and I want to be absolutely certain that I am getting the proper capacity. Thanks in advance!

How to Fuse your Solar System
By Stephen CliftonTechnical RepresentativeWhen hooking up your Renogy system, the best way to add protection is by using fuses or circuit breakers. Fuses and circuit breakers are used to protect the wiring from getting too hot and also protect all devices connected in the system from catching...
