Hey guys, me again. Lol.

Binky recommended Keto disconnects for my batteries, so I've got two on order, should be with me next week.

Now my issue is that I could only get 80A fused ones, but my inverters won't take that amount of current.

So the actual MC4 connector used to connect the battery is rated at Max 50A.

The recommended charge/discharge of the battery is 80A.

The max charge/discharge of the inverter is 35A.

And my 4 batteries together at 48v each with a maximum draw of 6kw, would work out to be 31.25A. The actual batteries can run at a 15sec peak of 200A, and a 15min peak of 120A, with a max continuous of 100A


So, what size fuse should I put in my disconnects? I can find 32A and 50A, at CEF, not sure about elsewhere.

Cheers,

Jay
