Victron Energy Orion 12/24-Volt 20 amp DC-DC Converter Non-Isolated, High Power

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.

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.

Works as designed, fan when it does come on is quiet. This unit isn't Bluetooth like my other Victron products.I use this converter to charge my Bluetti AC180 which is a 1152wh lithium battery bank. I use it to extend its battery life during power outages at home by connecting the Victron converter to my 200ah or 2564wh lithium battery bank to charge the AC180. I run a refrigerator and a large upright Freezer and my 75" LG smart TV while the power is out. Works great and I get about 280 watts feeding into my AC180 Bluetti which limits its input charge to 10 amps. thru the solar charge port.Nice converter so far. The adjustable voltage dial is suppose to bust the voltage up to 30 volts but my Victron 12/20 only busts to 28.6v turned all the way up.Without the Victron Orion converter I was only getting about 100 watts of charge capacity and now I'm getting 280 watts of charging which is almost triple the amount of charging I was getting.I recommend it if your looking to increase your charge capabilities.

I have two of these installed in my van to keep my Delta 2 Max charged while driving. The Delta 2 Max has two XT60i ports each capable of 500 watts but if they only see 12v they'll only charge at 80 watts assuming it's connected to a cigarette lighter.This allows me to step up the voltage to 24v which when combined with an XT60i cable lets me hit almost a full 500 watts. With the two I can almost 900 watts charging while driving.I love the fact that they have a separate input to easily switch them off. A single wire to a keyed 12v circuit and they only draw power while the engine is running so I don't kill my vehicle batter while sitting.They run relatively cool even in a tight place.

The first one they sent me worked but the fan was not functioning properly which led it to run noisy and hot. System function was all good but consistently running way too hot (had a temp gun on it but forget the temp, has been some time since this experience) Returned item and received an obviously used one in its place. Returned it again, received another used one, returned that one , then got one that didn't work at all. Returned that and gave up.Very obvious signs of prior use such as tool markings, missing packaging, missing pieces such as switch bridge, or bridge wire, or a lock washer. Hard to believe they would try to pass this stuff off as new.

Can now use recharge our EcoFlow while we drive. The Victron produces 400w per hour of pure sine charge from our car battery. Reasonable cost for a quality product. We can now charge between campsites as if we had solar installed on the roof.

On my second one of these, first one blew up due to my own error. It works very well and is high quality.I just wish the fuses were externally accessible, it's a bit of a pain to disassemble to get to them and I'm sure people have tossed them due to not knowing it has a fuse.Terminals are also a bit close together

It is a Victron, enough said
