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

Great products, works as expected. May cost a little more than other products of the same function. However, eviction energy makes a high end quality product and is worth a little extra money.

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.

Easy to install. Works great on my Humvee

Excellent device for converting from 24v to 12v. I'm using it in a large 5th wheel with a 24v battery bank in order to provide power to the 12v systems. With 70a of supply power there's no real need to install a 12v battery. The 70a capability provides more than adequate power to run our Lippert electric leveling jacks as well as for the day-to-day 12v systems in the RV. Construction is excellent and quality of the packaging was clean and neat. Installation was very simple by using a common ground connection to the 12/24v bus bars. Provide 24v on the input side and this will provide 12v on the output post. Heat generation is very low during typical operation. Output voltage is adjustable to match your exact needs or to account over voltage drop from the location of this converter to your main 12v panel. Absolutely would recommend this if you need to downconvert from 24vdc to 12vdc.

I initially bought one of the cheapo 24/12 reducers but it arrived with what looked like 12 or 14 ga wire and it just looked cheap so I returned it, bit the bullet and spent the money on Victron. Initially, I bought the 40 amp model but it came with the push on type connectors despite pictures on the page showing bolts. So I sent the 40 amp back and bought the 70 amp. The 70 amp does have the bolts for electrical connections, as pictured on the product page. It's been working great for me. I have it installed on a 24v solar system in my camper to reduce/supply the camper with 12v. The adjustment allows me to adjust the output down to 10ths of a volt. Pretty impressive. Also, I've contacted customer service twice with questions and they have responded both times and worked through my concerns with me.

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) 5.9.2021 Forgot 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'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.

Company won't uphold the warranty. Unit shorted out due to positive insulator melting on a 24v system. Everything installed properly and not in use when it shorted out and almost burnt down my camper. Sent in for warranty and was denied only for them to try to sell me a new one at a "discounted price" that was higher then Amazon price.

Einfach unkompliziert. Abschließen und funktioniert.

I run primarily a 24v system. This unit was purchased to run all the 12v devices rather than running several smaller dc converters which would be more inefficient. Simple install and works flawlessly. Can also be shut off by remotely if required.

Excelente

No heat issues, easy wiring, and consistent 12V output under load. Perfect for powering 12V gear from a 24V bank.
