Wondering if I need to go from my 10 amp circuit breakers to 15 amp to match the Maximum Fuse Series Rating of 15 amps?

I will have a set of three 100 watt panels in series with a circuit breaker. Optimum Amps is 5.7 optimum volts is 21.6 and shot circuit amps is 6.3 and optimum volts are 17.9. Maximum Fuse Series Ratings is 15.

So, since three panels will be in series, the amps will be close to 5.7, And volts close to 54. Its a DC circuit and rated volts are much higher.

My fuse is a little more than 1.5 times the short circuit amp rating, which is the rule of thumb I had used prior to finding the Maximum Series Fuse Rating.

EDIT: I think the intent of Max Fuse Rating is that I can Parallel two of these panels without a breaker. THe manufacturer, Renogy, does not have a recommended fuse size for a single panel. I will have two strings of these three panels and hope to add a third string.

Second Edit: My gut tells me sizing at 10 amps, around 1.5 times max amps is the right thing to do. I’m waiting from the experts for a reply.
