Victron Energy Orion 24/12-Volt 70 amp DC-DC Converter Non-Isolated, High Power

It is important for those thinking about using 24VDC or higher voltages. This unit states it will deliver 70 amps, but it will not supply the inrush current needed to start the motor. Place a 12VDC battery on the output of the buck converter or off the relay for your slides. Mine is a relay with a 60 amp auto reset breaker on it, directly connected to the batteries. I used a seal AGM battery for a lawn tractor for the slides and trailer emergency brakes.(Edit) 5.9.2021Forgot to mention that this is a great device, so far. It will run our furnace blower just fine. I used upstream/downstream breakers instead of fuses.(Edit 10.6.2023)I have been using this for over two years now and have left it on for as long as a month at a time now. I have had to do nothing to it. Still a great device. I will add that in my configuration it doesn’t charge my agm battery fully. Lucky I don’t need to much from it. I have not had to replace the battery even though I am charging it to only 13.2 volts.

I have a camper that I wanted to power while in storage. I was carrying the lead acid battery back and forth from the house. I had a little buck converter that I had rigged to use a tool battery to work some 12 volt items. The buck converter was able to run the lights but not much else. I saw this and thought I would give it a try. It powers the stabilizer jacks and runs the slide in and out. That makes it easy to do maintenance and load and unload the camper. It also allows me to start and run the fridge the day before packing so it is cold and keep the lead acid battery at the house on a charger until I am ready to leave. I don't think I would travel with it without the camper battery. It will also run the inverter I have for small loads. The only thing I would change on it are the posts. They are a little close together and a little difficult to wire without touching the case. I am considering a second one so that running the slide is not so stressful and I can run higher loads on the inverter.

Great performance.

I've installed a 24V battery system in my RV and needed the 12V system to run RV accessories, including hydraulic jacks and slides. I found this unit while searching for a DC/DC converter and at 70Amps continuous it would fit my requirements, I also found that for a short duration output 85Amps, therefore I installed an inline 80A fuse on the 12V side. Another little perk that this item has is its adjustable output, the manual states the default is 13.2 output, I left it at 13.2 the RV DC systems run better on 13.2 than on 12.0. Anyone who RVs knows that when using batteries as the 12V power source (especially lead acid), as the batteries drain the voltage subsequently goes down, One RV bonus I have by installing this unit is that the voltage will remain fairly constant, that is until the battery completes the discharge cycle.

Is does as described have no complaints. Build quality is good. It's easy to install. How are value for money I wish it would be a little cheaper.

I bought this for an RV 24 volt upgrade and this takes the 24 volt power from and converts it to 13.2 volts. I have this on at all times now for two weeks of use and ahas provided 12 volt power flawlessly to my RV side, to include the leveling jacks which draw 50 amps, with no spikes or dimming of the lights. This device also provides the 12 volts for the emergency breakaway.What I don’t like about it is how the wires are connected to the converter. Because of distance from the battery, I went with 2 AWG and found mounting this challenging. The top lugs could only fit in the 9 o’clock, 12 o’clock, and 3 o’clock position because outside bows out not allowing the lug to sit flat (See Pic).Also the studs for the posts only have a bolt on the bottom, and are not big enough with surface to surface contact for 2 AWG lugs. (Also Visible in Pic)The studs also come with a thumb screw which for mobile applications couple shake loose. I secured these thumb screws with Kapton tape (See Pic)Finally, ground lugs go to one stud for the 24 volt and 12 volt side. One stud won’t fit two 2 AWG lugs with enough threads to secure the thumb screw (see Pic). Perhaps one or two threads will catch, but not enough to keep tight.

I use this to step my 24VDC solar charged battery bank down to 13.8VDC for my ham radio station. There is no noticeable noise on the ham bands. I have been using this for a couple of weeks and plan to add a second for more current handling as I have two 12VDC HF Amps in my Ham Shack.I highly recommend this DC to DC converter for Ham Radio. 73 W9KJO

My unit was supposed to work on long periods reducing my 24 volt battery array to a secondary set of 12 volt battery array. (yes all in accordance and correct capacities)Unit broke down and was unable to get it replaced, as i only use it a couple of times a year and my guaranie had expired.Not worth the money or the vendor.I believe there are people in Amazon that sell that do care, however i feel this is not the case.
