Hey you 24 volt people. Orion 24/12 question.

I'm trying to decide if I need the 70 amp or if the 25 amp is enough. I plan on leaving the 12 volt system intact including battery. I may switch out the junk RV/Marine with a real deep cycle AGM. As Gust Avrakotos said, we'll see. What is your experience?

I haven't yet upgraded to 24v, but in what I have seen with my currect Victron equipment, 25a is more than sufficient for my 12v loads and will be what I go with.
That may change once I get the 12v freezer and convert my Starlink to DC power, but we'll see.

I've learned a 24/12-30 TR smart charger could be better than converter. Full three stage charging of the 12v instead of constant float.

I am not sure what the OP is trying to accomplish but as I have both the 12/24-15 (Qty2) and 24/12-70 (qty2) installed I can say that they accomplish different functions.

the TR Smart charger is designed to charge batteries from a different voltage alternator and the Orion is designed to convert battery power from one voltage to another (in this case 24 to 12V). We went with dual 70A as our hydraulic leveling system calls for a 125A max draw..... the key to answering whether 25A is enough is to search out the max amp draw on your 12V system and configure it to that

Your leveling system runs off your house batteries?

No all the house systems are 12V so you need the converter to run the DC systems vs. converting everything to 24V.

The hydraulic/leveling (HWH) system is 12V, hence the need for the converter for the 24V house batteries

Right, but the hydraulic system wouldn't normally be attached to said converter, would it?
Mine runs off the chassis batteries and that's what I understood prior as well.

Do you have a diesel pusher??

It probably has to do with the size of the system..... most pushers the 12V system runs from the House batteries as the system demands are typically higher.

Yes, it's a diesel pusher.
I understand the house system is separate and runs on 12v, so a converter would be needed with 24v.
But, my levellers run on the chassis batteries, which are inherently 12v and don't need a converter.

Hmmm.... mine don't. My levelers are on the same system as the hydraulic slides.... I'd be very surprised if your jacks draw 125A like mine do if they run on chassis batteries

In any case good luck with your conversion.

Maybe that's why, I have electric slides.
I don't know what they draw, just know I don't see their usage on the Victron system and they don't work with the chassis battery switched off.
