I have a Xantrex XW-MPPT60-150 solar charge controller. The moment came where I need to replace the fuse that protects the charger. The problem is that I need to replace it with Littlefuse KLKD 1 (600V DC, 1A Fast-acting) or equivalent.
The closest I found is a BOSS ceramic fuse 500V, 2A... and I don't know if I can be sure that this fuse will protect the charge controller in case of over current.
Here's a picture of both fuses, the old one on the left and the wanna-be new one on the right:
Can anyone help with this? It's a bit urgent because I'm off grid and I don't want to harm my system, nor face a short-out.
