Solar panel wiring and fuse question on 24 panels and an LV6548

[priorityelec]

So I went with the LV6548. It has 2 mppt inputs both at 4kw. I have 24 panels. My plan is to do a series of 6 panels, then parallel 2 of these together with an mc4 branch connector. I'd do this same setup for each mppt connection. I figure I'd put a 15 amp fuse at the end of each series just before it connects to the branch connector.

Each mppt would then have 12 panels hooked up.

My panels are the santan solar 240 watt panels rated at 37.2voc, 30.4v vmp, and 7.89 amps.

My big questions is how do I properly fuse this? Is an inline fuse at the end of each series enough? I'd have 4 total. Do I need a combiner box? Thanks for any help you can provide.

Mc4 fuse holder for each string (not actually required for 2 strings in parallel) sized by solar panels max fuse spec (found on the label)
No combiner box needed.
Recommend a disconnect near the inverter, on each circuit. For maintenance and emergencies.

The panels come with a 15amp fuse in them...so should my strings also have the same size...15amps?

They come with fuses? Sure that's not the fuse rating you are reading off the label? The configuration you are suggesting requires no fusing.

Oh, I think you are right
