Camper van with Orion, SmartBattery LiFePO4+smallBMS, MPPT, BMV700 and battery protect

Hi everyone,

I'm working on my camper van, I intend to install a setup with an Orion, smart Battery LiFEPO4 and its smallBMS, an MPPT (still unknown which one because solar panels not identified yet), the BMV700 and a battery protect.

I am pretty confident on the electrical part, but not really on the "control wiring" of the Orion itself and the smallBMS with the Orion, the MPPT and the battery protect. Could you please take a look a the following diagram ?

Thank you very much for your help.

Nicolas

How did you make it? Like this scheme?

I think this is a typical 2 batery situation (Starter battery and Service battery) with a Solar panel and a Orion.
Just curious if you are currently running this.

And how does it work when you are running the engine (so the alternator is used) and so the Orion is used... while the sun is also shining on your solar panel?
Then the orion as well as the MPPT is probably measuring a high voltage and both go into a very low charging mode.. ?
