installing a CTEK D250SA

[Broch71]

Hi,
I’ve just purchased a new Chausson Titanium 640 Motorhome.
The Motorhome has a CBE CB-516 electronic EHU battery charger.

I’m keen to install the CTEK D250SA C/W 2x100watt solar panels.
Can I leave the EHU battery charger installed as normal with the D250SA installed.
So effectively I would have options to use CB-516 if on EHU or B2B and solar if not?
Or do I have to disconnect the EHU from the wiring(or isolator switch)

Thanks in advance

Shirley it comes with instructions?
It's a good unit and a good brand so while it's good to check I suspect it will cope with all expected use cases.
