What is the output current of this converter?

The output current of this converter is 70 amps.

What is the conversion efficiency of this converter?

The conversion efficiency of this converter is 92%.

What are the applications of this converter?

This converter is widely used in motor, marine, electronic systems, dashcam, car, boat, RV, truck, golf cart, LCD TV, advertising screen, led strip light, monitoring system, solar pad and more.

Will this be ideal on our 24v power vessel to supply the 12v LED lights, sound system, VHF etc., or too powerful?

That is the purpose of a device like this. 70Amps is just the max it can output. The output is variable based on the live load.

Are there any issues charging a 24v LiFePO4 to a 12v LiFePO4 with this charger?

I use the Orion 24/12-25 to bulk charge my 12.8 volt nominal LiFePO4 battery bank from my other 25.6 volt nominal LiFePO4 battery as a supplement to the MPPT Solar Charge Controllers with good result.

This unit is listed as 70 amps, is that for the output (12volts)?

Yes, that is the full load rating for the 12VDC output.

I find the wiring instructions a little sparse, a diagram possible?

Only 3 wires, in 24 v, out 12 v and a common neutral.

How is overcurrent handled? Meaning if power goes above rating, does the device shut down, burn up?

It does not have a protection. No output breaker needed.

What is the wire size (wire gauge) recommendations for both input of 24v and for the output of 12v? (and what is the peak amp draw?)

This depends on the amount of current you’ll be drawing through the converter and the length of the wire runs.

What is its efficiency rating?

According to the Victron website, efficiency is 93% under normal operating conditions.

Can I use this to charge a 12v LiFePO4 battery from my 24v LiFePO4 setup and keep the 70 amps available?

Yes, if you have any problems, there is a fuse inside that you will need to replace.

My solar system is at the back of a truck, should this unit be installed close to the 24v source battery or to the 12v bank?

Put the long run on the 24V side. Be sure to fuse both sides, with the fuses as close to the batteries as possible.

Can this unit be run in parallel with a Victron Energy Multiplus 3000VA 12-volt pure sine wave inverter?

You only need this product for 12V appliances if you have a 24V battery bank. If you only have a 12V battery bank, you do not need it.

Victron Energy Orion IP20 2412-Volt 70 amp DC-DC Converter Non-Isolated, High Power

The Orion DC/DC Converter was reviewed by several customers who used the device for different purposes. While one customer found the 70 amps not adequate for their needs, others found it perfect for their RV and sailboat. One customer used the unit to replace the 12V battery on their sailboat, saving them 160lbs of weight in battery and charger. The unit was found to be easy to install and parallel with other DC/DC converters of the same model. Although customers found the directions cryptic, the unit worked great for most. However, the studs were Considered too short, making it difficult to get lugs on, and the side mounting tabs were too tight to the base, making horizontal and vertical mounting difficult.

Pros

Adjustable output
Easy install
Perfect for RV and sailboat use
Can be paralleled with other DC/DC converters
Replaces the need for heavy batteries and chargers

Cons

Only 70 amps, may not be enough for some users
Directions were cryptic
Short studs made mounting difficult
Limited mounting options
