60A 58vdc (48vdc) MEGA Fuse. Do they exist??

Need a 60a mega fuse for 48vdc system but can find them anywhere. Meant for Victron SSCC 150/45. Can't find any 70Vdc ones either. Anyone know where in the US these unicorns can be procured?

You can switch to a MIDI fuse holder instead of MEGA.

Amazon has 60A in those. You dont have to use the link I have attached, it is just an quick example.

So, I have the lynx distributor, really want to keep my power center for all my fusing if possible, any other ideas?

You ended up in a weird place in your system sizing between the mppt size and the lynx.

Upgrade the mppt? ;)

Given that the mppt has an internal fuse, could the OP use 35mm battery cable, and then rate the fuse to suit that?

Oddly enough there is a new 150-45 mppt controller ( new 150-45 ).

Perhaps the OP could clarify which mppt they have?

This150-45 takes 35mm battery cable.

This new 150-45 takes 16mm battery cable.

You could use a 125a fuse for the 35mm cable.

Maybe 60a for the 16mm cable?

Well, sorta. It's a small system. 370w panels in 2s2p, so the total Amps are low(er).

Could I use a 60a 70v fuse instead?

I dont see why not.

If it was undervoltage I would say no.
