fast charging an Oupes 2400w

mfeferman · Jun 13, 2024

Hi folks -
Complete newbie here. If I want to build a fast charging system, using a dc-to-dc converter for an Oupes 2400w, should I use a 12v->36v 30a boost converter and then split to each anderson plug, with some sort of protection (15a fuse?) on each anderson plug to ensure not more than 500w is output? Is there an easier approach?

Thanks in advance.

The manual is really unclear. What size are the Anderson connectors?

It's an Anderson power plug

Indeed it is. 15 amp? 30 amp? 45? 100? 125, 250? The manual doesn’t say.

Each one 500W max, 12-45v. With 500W, 12v, thats 41.7A. So they should be 45A at least, if specced above min. They don't look that big to me though.

Also, there is no reason to split a 30A converter, when each Anderson input will take 42A.

I would get a Pecron 500W car charger. $134, comes with cables. There are only 3 automobile use 12v >>40+V converters I can find. See my thread in this subforum on 12v >>48v converters.
Pecron, 500W 12 to 42v, $134
Ecoflow, 800W max but tests at 350-500 I've seen, $599.
Victron 12>>48v, $200, doesn't show up on most of their product sheets but exists. No cabling.

The pecron at 42v would give you 480W input to one port probably.

Who makes a 12v to 48v (56v) converter?

Victron only has 12v to 24v. For running a powerstation in a truck bed, there is no need for a full dcdc smart charger, as the powerstation already has its own "smart input" in all cases. Rather, all that is needed is a 12v to ??? Converter, where the ??? Matches the powerstation dc input...

It’s not clear from the manual if each Anderson can take 500W or if they are in parallel for a total of 500W.

The housings for the 15, 35, 45 are the same and intermatable between that same size.

Each one takes 500W.

Then I’m with Dave:
/* I would get a Pecron 500W car charger. */
Or two.

Unfortunately, those do not look available anymore. I think I'll build two. :/. I don't see any other option

The webpage specs say 500W each, 1000W total.
