Votronic solar connection lead ? (1 Viewer)

[Gerryatric71]

I purchased the Votronic lead ( Article 2007) to connect a Votronic MPPT 250 to my EBL 101 electroblok.
The instructions are straight forward however I have query. The X lead connects the output from the solar controller to the electroblok with a three slot plug which is shaped so only fits one way however the instructions (to me) indicate that the violet cable is the positive and is positioned at the top of this three pin connector but the socket on my ebl means due to the shaped plug/socket it is at the bottom.
Either the loom is wrong or I am misunderstanding the diagram.
I have tried to find a wiring diagram of the ebl 101 but no luck.
Can any expert help as the rest of the wiring is ready to go and I cant afford to bugger up the ebl.

EBL101 dia. attached.
Pin 1 on EBL is Neg, Pin 2 Starter battery, Pin 3 Leisure battery.

If it’s shaped to only go one way surely that’s the way it fits.

Are you saying it should fit the way it shoes on the above drawing.

Thanks very much, maybe I overthink things in my old age.
I am now looking forward to tomorrow!
Thanks again.

If you look at the EBL front panel you will see a small '1' with an arrow, next to the 3-pin connector. That shows Pin 1, and the direction to count the other pins. So on the EBL, Pin 1 (negative) is at the top.

I'm sure the instructions tell you this, but the solar power goes through the 'Solar' fuse, so you have to insert a fuse in that slot for any power to flow. A 15A fuse, I think.

Thanks, 15 amp fuse max on my ebl 101. Cheers.

There's download instructions in post #21 of this thread.

Problems in the bedroom department!

Hi All Help needed. we have a Pilote G740 has a fixed island bed at the rear. we have recently had some work done because hab battery wasn’t showing any charge on control panel. That has now been fixed by an engineer. We have just come out to the van to get ready for the off next weekend and...

It can be increased to 20 amp if needed.

I was told that it shouldnt on the 101 but as my solar array ( sounds more impressive than panels) will not exceed 15amps even on a good day I’m happy to leave it at 15a. I think electrobloks are a bit of a minefield.

I just connected at the rear of our EBL 29 from the Votronic MPP350, where the battery wires enter the unit, much more simple and no worries over the capacity of the front connectors that are available.

I think electrobloks are a bit of a minefield.

To be fair, when the EBL101 was designed hardly anyone had more than 100W of solar and 100Ah of battery capacity. Schaudt make a 'high current unit' which will take large solar arrays, big B2Bs and larger battery banks, incorporating its own measuring shunt that communicates with the EBL. It's a bit rare though, people just bypass the charging bits and go straight to the battery.

Yes I agree, in fact my feeble attempt at solar harvesting is really just so I dont have to use 240v to keep batteries charged. However I see Yuasa say that batteries should not be kept on permanent charge either mains or solar.
Also I have Yuasa L36 EFB battery and I understand the choice of charging mode is dependent on your type of usage.
”The Yuasa L36-EFB is technically wet lead but because of the way it’s built it will withstand being charged at the higher rate of the Gel setting. You need to analyse how you use the battery. If you are a power user, it might be better to charge with the Gel setting so it charges up more quickly but if you are a light user the Wet lead setting would be better. Charging the battery on the Gel setting will reduce the recycle rating.”
