[bobimport]

i am looking to install a DC to DC charger in a chevy express 3500 . I have a 48 volt system and all i see is 12v 12v chargers , 12v 24v. The 48 volt ones say 48 v IMPUT.
someone point me to the right one .

This may be used for an 48V LFP battery charging from your 12V alternator. It's not a real charger with a charging profile but it's output is 56V to fully charge the 48V LFP... in case you're using LFP... but they also have a 12V to 48V boot converter.

Surely victron has an Orion unit for this, right?

This says 3 amps ?

yes, just 150W.

Mhh, I can't find one from 12V to 48V only from 24V to 48V...

The link wording is wrong. But it takes you to the 12v to 48v model.

with a bit of DIY it could be a lot cheaper - I found a 1,800W module for $26.

That is only at 60V input. For 12V input @ 30 amps, it is 360W.
Assuming ideal conversion, that translates to 7.5A@48V

You're right! I was too fast with my post and should have read the details before

But anyway 360W is not bad for a module with a price tag of $26 (it's about the same power like e.g. the Victron 12V/12V 30A Orion DC-DC-charger- just as a comparison about the price for a device with the same power - even with different voltages and other area of application).
