I think it’s a CBE system,not Redarc.

No not that one - that 3-way is for the solar connection. Some EBLs have a starter battery feed to the centre pin. But not the EBL99, unfortunately.

Thanks Autorouter.

But I AM connecting solar controller - so dont understand why "No not that one"

Charlie Lun (The guy I am buying from in NZ) says this photo is the "order 2007" cable that Votronic supply for this job, and I thought the 2007 was the one you were referring to. I thought buying it was the simplest option, but even that seems to be getting complicated now.

I am happy to make one, but don't have a diagram, and unclear what cable rating to use.

If a wiring diagram were miraculously to appear, maybe it could be stored in the MHF resources section for future members ?

( and I've got too little hair left, to be frivolously tearing it out )

Just to confuse you even more the Votronic cable does not have the starter battery wire just two wires in the loom which is OK for your EBL99.

autorouter has described alternative ways of connecting to the starter battery but if it confuses you the simplest way for the starter battery charge is just connect straight to the starter battery.

Sorry, I thought you were talking about connecting the starter battery to the second (trickle-charge) output of the solar controller. This 3-way cable is fine for connecting the main solar controller output to the leisure battery. Pins 1 and 3 are intended for this.

However for the starter battery trickle-charge, it won't work. Some EBLs have the starter battery connected to the centre pin, Pin2, but on the EBL 99 it's not internally connected to the starter battery, so it's not much use. That's why I described the other two ways to sent charge to the starter battery. Or as Lenny HB says, just run a wire direct to the starter battery (with a fuse, of course - 5A should be big enough).

My ambition here is to use my PV to charge both Cab & Hab batts through Votronic Duo 250a MPPT whilst van is standing in storage with no EHU.

I landed on Votronic cos they're supposed to be EBL compatible, although now realising that's perhaps not so important / useful

So the simplest method which won't blow up any of the other electronics, and without ripping the floor up, or having wires trailing across the floor.

I was going towards the 2007 cable set cos it seemed to achieve above factors

but I seem to keep going in circles and getting back to square one with depressing regularity.
