What are the proper size blade fuses for the KID?

Hi Phillip..,  Welcome to the Forum.

Found this in one of the KID manuals:

"Type ATC   32V  30 Amps Max"

Also on the MidNite Solar site,  there is a reference to Plug-in Breakers:

Do not know if current generation KIDs ship with one/some of the above breakers.

FWIW,   Vic

why am I thinking that they have 40 amp fuses in them ? Now I will have to go look . Yes mine has 40 amp fuses in it.
Mine was one of the original beta Kids but seems to me I sent it back in for repair sometime and it came back with a new and improved inside board.
And the 40 amp fuses .

Hi Larry,

My KID is also a Beta unit,  and all original.

It came with,  and still uses (the original) 30 A fuses,  in all three positions.

Did not take the time to look at all of the KID Documents listings.

You are probably correct about newer KIDs using 40 A fuses,  at least at certain locations   ...

Did Search 'Kid',  and 'KID fuses' nothing jumped out noting 40A fuses,  but did not read every Post for each search hit.

Am sure that someone will chime-in with the absolute bottom line.   73,  Thanks,  Vic

My Kid has a 15 amp fuse in the Clipper fuse port . Pretty sure I never messed with it but who knows - can't remember everything in life !

I seem to remember that we added a 40 amp internal fuse as well as the replaceable fuses but I can't really remember.

We may have opted to not use that safety fuse ?

HEADS UP ALERT !

Not All Fuses are the same, many Imported offshore fuses are JUNK and problems are occurring.  PLEASE stick to Known Good Quality Brand fuses from Bussman/Eaton (BlueSea uses them exclusively).

A Good Recent Article on Fuses:

So, my Q1 2025 produced black KID came with 40 Amp fuses installed (see below).
Could some of the Midniters out here explain to the lay folks why a 30 amp max everything rated electric/electronic device they produce ships out with 40 amp fuses?
Were you just out of the 30 amp fuses?

You can run right up to the limit of 30 amps and not have to worry about a fuse blowing.
If it was making 30 amps and you had 30 amp fuses in it , they could blow. The Kid I believe in theory can do 40 amps but it was never certified for that and the software limits never expanded.

I think my Kid had 40 amp fuses in it but I don't have it now to check.
If you want, just swap those 40 amp fuses for 30 amps.

How old is your Kid ? It could be that the later versions of the Kid had 30 amp fuses . The later versions  came with a different wiring box so that may have limited the wire size to 10 gauge which is 30 amps. Otherwise you could use 8 gauge wire for 40 amps.

Here is some past  discussion about the 30 vs 40 amp fuses https://midniteftp.com/forum/index.php?topic=5618.0
