I'm trying to spec out a leisure battery charging system for my Auto-Trail Motorhome. I currently have 3 X Yuasa L36EFB 100Amh batteries in parallel (12 volt).
I'm installing a 100 / 30 smart solar charge controller and a couple of solar panels. This will be wired direct to the batteries.
What I'd like to do is to have the batteries charged while the engine is running. The vehicle is a Fiat Ducato 3.0 litre diesel (2016 model) so Euro6.
What Victron kit will allow me to charge the batteries AND protect them from over-charging?
I'm considering the Victron Buck/Boost but I understand that this would not have a multistage profile and could overcharge.
This is really the start of my journey to a fully off-grid solution so in the future will be upgrading to Lithium batteries, lynx connection boxes etc.
Thanks for any help
