Sargent charge controller issue

[garysavannah]

Can any funsters help!
Wanted to change the onboard controller to Victron shown in image below seen many posts on doing this but none with this controller.
I’ve marked image below with no 1 and 2 on the live feeds and circled where they connect to, clearly on 2 separate terminals on the panel.
If I’m to maintain all functions on the control panel do i 1. Join both these feeds together and put into battery live feed terminal on Victron or
2. Connect only one of them to battery live terminal on Victron.
Lost at what to do!
Any help appreciated. Panel is Ec328.

An expert will be along soon. I would think that as you are going from a 2 battery output to a single battery output you should put #1 in to the victron, the panel cables in to the pv feed and use a battery master to feed the cab battery. You should be able to use the cable #2 to feed your cab battery from a battery master. I really wouldn’t put #1 and #2 in to the victron, doesn’t feel right but very happy to be schooled.

Edit. Plug #3 appears to be an earth so may need to go to the victron too.

Didn’t think of your option, thought there might be a way to do and maintain the current system functions, it seems the starter battery gets neglected then.

Correct the other cables I understand it’s just the 1 and 2 I have issues with.

I’m sure an expert that knows your psu will have the perfect solution where you don’t need a battery master. Are you wedded to the victron? There are some other decent dual controllers out there but a bit bigger in size perhaps

The Votronic Duo MPP has dual output - one for the leisure battery and one for the vehicle battery. If you use Victron you need a battery master or Ablemail to keep the vehicle battery charged.

As does the epever duoracer, but big. I use it with a little Bluetooth dongle.

Depending on total capacity of your solar - will the 75/10 be capable or do you need one to handle larger capacity ?

I was afraid of that, that shouldn’t be to hard to add

I may add another panel and fit the Victron I have now brought to that and go with one of your suggestions. Although I have 280 watts already going direct to batteries. They do say you can never have enough solar

Yes it’s a 10amp controller the same as rated in the image it’s just the compatibility I didn’t take on board. Just wanted a better unit installed to get max from the Sargent setup. I also have 280 watts running direct to batteries via a Victron setup.
