Orion XS 12v to 24v charging

Can the XS be connected to a 12volt charging system and charge a 24 volt battery at 50 amps ?

The new Orion XS 1400 is limited to 50a input, and 50a output.

5

So, will that unit actually allow me to have a 12 volt input and a 24 volt output ? It say it’s programmable but doesn’t say if the input and the output have to be the same voltage

The data sheet gives the input and output voltage ranges.
Link as above.

The description on the product page says “mixed voltages”

Take a look in the demo library in VictronConnect.

thank you all for taking time to respond to this post

I found nothing in the demo library not even a photo of the Orion, but very nice videos with great music.

The advertising for XS 1400 says “connect any alternator to any battery” so I’m guessing a 12V alternator could charge a 24V battery via the XS 1400 if correctly configured.

12V input at 50A would obviously not give 50A out to a 24V load. Probably 24A at most given the claimed 98.5% efficiency.

thank you for the reply James, that’s what Im guessing as well, however,I was hoping to find someone who has actually done it and can confirm this works.I feel like more will be changing their solar systems to 24 volts but we are just not there yet.Thanks again and make it a great day.

let me rephrase this question, can the XS 1400 charge at 50amps 24 volts from a 12 volt vehicle charging system, or will it be sliced in half to only 25 amps - the efficiency so more like 24 amps or so ??? Does anyone here know the answer, or has similar configuration proving the results?

As ever, the details are in the datasheet. The maximum input current is 50A. Therefore, if you are nominal 12V in you have max 14 x 50 = 700W, so charging a nominal 24V battery you will only have approx. 25A output.

In the case of charging a 24v battery, from a 12v battery, the limit is on the 50a input.

The output power, will be limited to the power at the XS input.
If the voltage is 12v at the XS input (due to the engine not running/voltage drop on input cables) you have a limit of 600w.
With an output power of 600w, output current available would be I=P/V.

Battery at 24v? 600/24=25a.
Battery at 28v? 600/28=21.4a
