WildThingsKev I'm pretty certain that the CBE will only pass a trickle chargeo to the vehicle battery when the mains charger is connected. There is a signal wire from the mains charger to the CBE panel which must operate a relay to close the charging circuit to the VB. So, if the solar reg is simply connected to the same terminals as the mains charger everything will be fine except that the VB will not get trickle charged.

Sorry they won't upload as they are .xps files but if you pm me with your email address I'll send them to you.

thanks Kev pm sent
right about cbe phoned them there technical help are on holiday till end of Aug then they are at dusseldolf then Palma so will be available end of sept.
what a service !!!!

That may well be correct for the ds-300. The advice I received was for the ds-200 not the 300 which may have a slightly different layout. The one fitted to my current van has a slightly different layout from the one that was fitted to my Arto..
I think the basic advice still applies though, connect the solar via the input terminal on the CBE panel - not straight to the batteries.

Basically, because the CBE panel distributes any input charge between both batteries you don't want a solar charge ALSO fed independently to both batteries. This can mean that the solar and mains charge conflict with each other (if that makes sense?) unless you disconnect your solar panels every time you're hooked up. Therefore the output from the solar regulator should feed into the CBE panel on the same terminals as the mains battery charger thus allowing the CBE panel to decide on charge rate and distribution. This obviously works best with a very basic solar regulator. The negative feed from the regulator goes to the "masse" terminal and (on the linked diagram) the positive goes to plug 18, terminal 2. This can vary slightly depending on how old the control panel is, just trace the positive output from the mains charger and use the same terminal.

By using this method the CBE panel monitors the battery voltages and directs the solar (and/or mains) charge as required. It also means that the solar output is monitored and is visible at the remote panel so you can see how much current your solar is inputting without the need for a separate solar meter.

This link goes to the instruction book which contains panel layouts and circuit diagrams:

Your own panel may differ slightly.

PS: I should add that this is a summary of advice given to me a few years ago by a CBE technical chap and related to the N&B Arto that we owned at the time and using a basic solar regulator with a single output.

Harrison (see His thread "Carthago prewired for solar " ) and i are interested in making the solar connection on carthago's that have been factory prewired

yes you are correct the readings are when the electric hook up is connected and with a seperate tester at the battery and in the van which give the same readings. Today i will try what you say and come back on here with the readings
I have been in touch with CBE and awaiting there comments and also requested a wiring diagram of the boards as i may be able to get it repaired. there appears to be no obvious damaged to the board.
i have also been speaking to travel world
its anoying because the van is unusable at the moment
thanks for all your help so far
I doubt CBE will be much help, I also doubt they will give away their circuit diagram.

You'd have more luck Googling the model number of the control panel, if it shows one.

Not reset, re seat, IE remove and replace.
