Have the EPever Tracer 30 amp 12 volt charge controller but blew both 30 amp fuses, problem is these are not pin or blade fuses, have contacted EPever several times and they just play dumb, have tried harware, auto parts, Ebay, Amazon and nothing, problem is the PINS or BLADES are built into the circut board, anyone have any spares or sources, have gone back to my old PWM controller which is working surprisingly well especially with Lithium batteries, if I can find fuses great if not I will scrap it, Spoke to Renogy today and they too do not have replaceable fuses in their charge controllers, makes no sense to me.

Do you know how to search for matching images in Google? I would upload that pic into Google and see what comes up.....

Did it, the one it came up with had pins and was much smaller and just a lot of green stuff totally unrelated.

Ok.. Wait my Epevers had standard blade fuses (soldered in).. Without the blade contacts, how does that fuse even connect to the board?
Please show a pic of the top of that fuse...
I think that is a standard automotive blade fuse and you left the legs soldered to the board (yes they are soldered in). You require a good 40W iron to remove them (and some skill to not kill the board by lifting tracks). Also a solder sucker makes it easier, but not essential if you know how to unsolder things.
If you grabbed it with pliers and yanked it out, then the legs are still there in the board.

My Epever40 blew fuses this summer. They are standard blade fuses and I'm betting your blades are still in the board as they are soldered in. I bought 2 40amp fuse holders with wires. Soldered those wires to the existing blades that are still in the board, and just routed them outside of the case. Had to trim a bit of plastic on the sides for the wires to come out of the case.
What your pic is showing is a standard blade fuse with the blades pulled out. They are still soldered into the board.

Solder in a plug in set up on the board, make it easier to service next time. Chose a nice simple low cost, easy to obtain fuse size.

Before going to too much trouble....why did they blow?
You may want to do a simple jumper wire to new fuses set up to make sure the thing even functions?

You dont use a external fuse on the charging side of the CC?

I use external breakers on both the input and output sides of every charge controller. I have only had equipment failures or a charge controller breaker trip or fail because of lightning strikes.
