Centaur - 3 Ouputs to a Buss

In order to gain more amps out of the a single Centaur charger, is it possible to simply attach all three output to a buss - and thereby gain 3 times the current output?

Ah. Thanks for the clarification. The wording could be a little better in the literature if that's the case!

Just take a look at the prices. There would be no reason to buy a Skylla 24/100 for 1500€ if you can get 90A (3x30A) with a Centaur 24/30(3) for 600€.

Hi there. I'm new here but had basically the same question. The pdf for the centaur chargers from the Victron website (https://www.victronenergy.com/upload/documents/Datasheet-Centaur-Charger-EN.pdf) says this:

"Three outputs that each can supply the full output current

Three isolated outputs to simultaneously charge 3 battery banks Each output is capable to supply the full rated current."

It still doesn't answer the question of whether we can combine outputs to multiply the amperage, though.

No a 50A Centaur can give you max 50A spread over all outputs. Not 3x50A.

It can deliver the full output current at all outputs but only if there is nothing connected to the other or the other connected batteries are fully charged.

No the max output is spread across all inputs so if you max it on one then add a secound all that happens is each one takes 50% add the third out put then all will reduce to 1/3 if connected to the same bus that is
