Battery in-line fuse size

[Rioja John]

I have 220 AH of Gel leisure batteries, a 75/15 Victron solar regulator and 200 watt of folding solar panels what inline fuse should I use on the positive side to the batteries, Is 20amp the size fuse that I need?
thank you,

John.

I’d start with 10A

200w should generate 12A ish (max) on the battery side.

And the Victron 75/15 comes with a 25A fuse on board.

But remember the fuse is there protect the cable, not the device.

I'd be looking at a 20A fuse for the battery conection.

You can go with the 10A, but if it starts to get warm or hot under full charge swap it out for a 20A. (Assuming your cable can take 20A)


...


Remember the fuse goes at the battery post end of the cable.

I have a midi fuse holder and need a 20A fuse for it. The midi fuses only go down to 30A.

Anyone know if these ASF ANL fuses are ok to use?
