I just got one of these the other day. Found most of the connections needed to be screwed down more, most did half a turn, but the ones on the fuses for the solar leads were totally unscrewed. otherwise, it works fine.
Mine were all reasonably tight. Still got a partial turn on about half of them. I also installed another one but needed to put #4 wire in the output breaker. I had to move the breaker to a different location in the box so there was a straight shot to the breaker.
I am not sure. You would need to check your local code. I do not have one but I have a second breaker next to my solar charge controller. My system is off grid.

= another SUGGESTION = instead of aiming your MAIN +POSITIVE+ & Main -NEGATIVE- cables down into you conduit --- where it will direct WATER into your Underground RUN why not install a "WEATHERHEAD" and run your wiring UP through a weather-tight connector Above your Combiner-Box & include a "DRIP-LOOP" below the Combiner-Box installation ? ... just a suggestion ...

I guess it is a panel that doesn't have a high enough voltage to charge a 24 volt or higher system. My 100 watt panels have an open circuit voltage around 20 volts.

Would a PV disconnect switch be required also, or would the breaker in the combiner box serve the same purpose?

Just hooked up a combiner box myself. Nice set up.
I was told that ‘tinning’ prevents the wire from corrosion. A solar installer told me that. Take that, with a grain of salt, I reckon!
I think tinning is a better choice than ferrules.
Can you please tell me,Do them box's have blocking diodes
No they do not have blocking diodes.
That's funny.
Nice.
= since you are utilizing STRANDED Copper WIRING
might I suggest you install FERRULES on the ENDS before INSTALLATION >

got the same problem with my cat..
= another SUGGESTION =
instead of aiming your MAIN

& Main
-NEGATIVE-
cables down into you conduit --- where it will direct WATER into your Underground RUN
why not install a "WEATHERHEAD" and run your wiring UP through a weather-tight connector
Above your Combiner-Box & include a "DRIP-LOOP" below the Combiner-Box installation ?

just a suggestion

???
what - in - the - HELL is a 12-volt "PV" Panel
???
just CURIOUS as I see this 12-Volt reference quite often & NEVER understood it ???
