The top part fits but no shoulder to hold them in place, nothing else in the store that would fit.
I didn't think it would be this hard to find them since its a pretty common panel fitting.

I searched high and low looking for crimp terminated banana plugs that could hold a large gauge cable. Best I came up with was these : Red Insulated Type Banana Plug - Altronics

If you throw the plastics away the connector itself looks much like the one in your picture. The only problem is the brass is pretty brittle, so crimping on anything less that about 8awg (which is a snug fit in the female end) can be dicey. If you soldered the wire in then it'd be pretty close to what your picture shows.

I had a look at similar ones in jaycar but they didnt look suitable without me buying one and opening it up, the tips are fine just the rest is not quite up to it.

Why not convert to mc4?

Because MC4 doesn't fit in the junction box or the fitting the cable goes into as per the pic above, and if you look at a house panel it will have the same fitting.

I've made several sets of cables from the guts of the one I linked. 2 soldered (6mm2) and one crimped (8mm2).

Sorry I wasn't clear, I mean add mc4 pigtails, so make it same as house panel with cable out of the diode box with mc4 on end.

They don't fit, tried that first and the fittings i need are house panel diode box connectors as per my pic.

I think johnp38 meant make up a set of pigtails using the old cable and fit MC4 connectors at the other end.

Or you could find a junction box that is the same with the MC4 pigtails and disassemble and use the pigtails.

Does the junction box have a part number?

The panels came with cut lengths that i used with screw terminals to join into the rest of the cabling but i want to delete join to make it neater and more moisture resistant, wires are in conduit so not a big problem.
Seems pointless using the MC4 connectors if they aren't going to be removed .
