assembling my components for the sprinter build this spring.
I saw a video or two on utube , but thought best to ask here , is using a victron 12 12 30amp dc to dc charger safer , more max friendly in the long run , sacrificing the faster charging time that a renogy 40 or 6o amp would deliver ?
I plan to have solar as well , but I think its good to cover all the bases the best you can for all situations
thanks in advance

AC200MAX will limit the charging current. When using a 12V DC-DC charger, the machine will limit the current to around 8A, and the maximum charging power is around 100W. Even if a larger current is selected, it will still be limited to 8A. Note that the input source needs to be set to ‘Others’.

The max PV input current of AC200MAX is 15A. Due to the current limitation of the vehicle charger, the input voltage of the solar panel needs to be higher than 30V to avoid being limited to 8A.

If you want to see higher charge rates, you need higher voltages. I would suggest a step up converter of either 12 to 24 or 12 to 48 volts.
Thank you Scott and admin at Bluetti , after I posted , I realised that I should of been talking about a dc to dc converter , not charger.
With regards to a converter , can I ask what a safeish range( 12 24 12 36 ) would be with regards to hooking up one converter into my sprinter, that would be used more than likely , at least half the time as twin factory skylights plus my maxx air fan negate solar on the roof , but I will still have two portable arrays that will be stored safely and securely between wall and murphy bed .
What a great forum , thanks again
With regards to isolated or non isolated DCconverter , Should I use the isolated , as my 200 max is freestanding inside the build ?
24 to 48 volts would work fine. I use a 48 volt personally. The higher the voltage the higher the charging watts will be but this is at the expense of a higher alternator load on your vehicle.
Either one should work fine for your purpose.
