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.
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
Note. Figures do not include any losses.
Did anyone already install this in a 24 volt system with a 12 volt starter battery? I’m trying to finish my electrical drawing but i’m a bit baffled about the non-isolated setup and combining 12 volt and 24 volt systems. I understand that the positive wire runs from the starter battery (12 volt) through the orion xs converting it to 24 volt to the positive busbar and then the battery. But there is a connection running from the negative house battery (24 volt) back to the 12 volt starter battery. I have connected the chassis gnd point also to the negative busbar.
But confused what happens on the negative pole running from a 24 volt system back to the 12 volt starter battery and what to do with the GND connection on the Orion. From other sources i see that they connect it to the negative wire coming from the negative busbar. What am I missing or am I overthinking it? Couldn’t find anything related in the manual concerning combining 12 volt input and 24 volt output.
Not much, its just a common negative. One system has +12V in regards to negative, the other has +24V. The only current that will flow on the common negative from the 24V system to the 12V is the one that the Orion “creates”.
You also connect it to the common negative.
Okay. Thanks! I was definitely overthinking it then
