input anode fuse box

You wriote: "Although we both avoided translating the term "anode", you complained this lack."

That's the whole point, that you appear to have failed to realize: I specifically did not avoid translating the term 'anode' — I simply realized it was a source-text error by an obviously non-native writer, and translated it (correctly, as I am convinced) by 'positive terminal' (which as an engineer yourself you will know is also another term for 'anode', albeit not interchangeable).

Was the client satisfied with this term? Or did he explain it?

For me, a term like "Coffret (ou boîtier) à fusibles des anodes d'entrée" was far out of being considered. That's why I did not check the term up to now. The point is, what function has the "anode". An anode is normally a gate or connection of a semiconductor or vacuum tube. See

Thyristor
Type Passive

Pin configuration anode, gate and cathode

Spark gaps a one example of the devices containing anodes and cathodes and which are used and must be used in outdoor PV installations to protect against lightnings.

This is shown by Google image search if you enter "fusibles des anodes d'entrée"

I see no relation to a smart PV combiner box. So it's probably wrong.

As engineer you should know that fuses are always in line and surge arresters (SPTs, surge protection devices) are connected in parallel to the supply terminals. This makes sense. Fuses do interrupt overcurrent and SPTs do short-circuit conducted or induced overvoltage surges from lightning strikes. Both devices are required for outdoor installations, therefore.

All the quarrel started with your disagree. Although we both avoided translating the term "anode", you complained this lack. Please consider that the source text is obviously not written by a native English speaker, perhaps a translation from an East Asian language. We have to reflect, what a combiner is, and what it contains. Anodes and cathodes are electrodes. Spark gaps have electrodes. These parts are essentially for outdoor installations. That’s all.

Note that although your voluminous quotes mention 'electrodes', there is no mention of the possiblity of any of these being either 'anodes' or 'cathodes'.
'anode' is another word for 'positive terminal', 'cathode' for 'negative terminal' — and it's obvious this source text is not written by a native EN speaker, so they may well have wrongly used a term similar to the term in their own language, or simply lifted a dictionary definition without understanding the nuances of the terms.

Where on earth are you getting all this about 'spark gaps' from?! OK, they may be found in a combiner — but there is nothing in the source text to imply this is the case, so it is only speculation on your part — amounting, as I said to over-interpretation.
In any case, even if the anodes and cathodes here were anything whatsoever to do with spark gaps (which I strongly disbelieve) — why on earth would you have fuses on the inputs to spark gaps??!! Now THAT would make no sense whatsoever!

Please note that spark gaps contains 2 electrodes (anode and cathode). That's why we should consider a surge arrester, i.e. spark gap, what is standard component of a combiner box).

A spark gap consists of an arrangement of two conducting electrodes separated by a gap usually filled with a gas such as air, designed to allow an electric spark to pass between the conductors.
:
Apart from the anode and cathode voltage drops, the arc behaves almost as a short circuit, drawing as much current as the electrical power supply can deliver, and the heavy load dramatically reduces the voltage across the gap.
