Victron Energy Orion-Tr Smart DC to DC Charger (Bluetooth) - 12/12-Volt 30 amp 360-Watt - Battery Charger for Dual Battery Systems - Non-Isolated

When it came time to upgrade my motorhome to Li-ion house batteries, there were two choices for protecting my alternator: a DC to DC charger or one of those timer-style systems. After reading and listening to many experts, I chose the DC to DC charger. Since I wanted a DC to DC charger, there was really only one top-of-the-line company, Victron. I was able to find the product that I needed for a little less than ordering directly. Same product, less money! The instructions were absolutely clear, and as I ordered, I was able to look ahead and get all the parts I needed. The only difficulty I ran into was separating the ignition and battery connect wires in my coach. Once I figured that out, the installation went quickly. To configure the charger, I just needed to install the application on my phone and connect via Bluetooth. The application walked me right through the setup to include whether you have a smart alternator, ignition wire, etc. There was NO trial and error, configuration was easy and right the first time. We are only part-time campers, so I have only used the system twice, and most of our driving, we use the generator to run the overhead AC units. This is primarily a secondary method to keep our house batteries charged. In the few tests, it does exactly what is advertised. The Li-ion battery is getting 14.5 volts while minimizing the draw on my alternator.

The Victron Energy Orion-Tr Smart DC to DC Charger (12/12V, 30A, 360W) is a fantastic solution for maintaining your batteries. With Bluetooth connectivity, it’s easy to monitor and adjust settings via the app. It’s highly efficient, providing smooth and reliable charging without overheating. Compact, durable, and perfect for RVs, boats, or off-grid setups. Highly recommend!

Originally had this installed in class B van. Never seemed to work well and I was always worried about the alternator being over worked. It is designed to turn off after after 15 min and turn back on after 20 minutes off to give the alternator a breather since Li batteries and overwork an alternator (they will take the amps as fast as you can give them for the most part). I changed over to a DC to DC charger (Victron Energy Orion-Tr Smart 12/12-Volt 30 amp 360-Watt DC-DC Charger, Non-Isolated (Bluetooth) ) for a better piece of mind. Since most wire runs are 4 going back to the batteries in a van the max charge is 100A (which would take 3 hours to achieve at the cycling). The DC to DC will do 30A continuous. So you really aren't losing out on much. ESPECIALLY if you are driving 3 hrs!!! The piece of mind that if my alternator goes, it won't be because I over taxed it. It Power were that critical, I would put in a larger alternator or a second one.

Easy to install. App kept me in line to watch the performance. Satisfied with the performance.

We've been camping in converted vans for over ten years, with ever-evolving electric systems. All three of the vans I've converted have had a battery-based, solar charged electric system. The last van and our current one have both had ample battery capacity, with the limiting factor being our charging capacity, especially in less than ideal conditions. I finally decided to install a DC-DC charger, after kicking the idea around for the last three years or so. I'm so glad I did. We haven't had a chance to camp in the van yet, but it's already making a difference. It's early March as I'm writing this, and solar conditions are far less than ideal here in New England, but our batteries are staying fully charged, despite having some fairly heavy loads on them. I made a 3-gallon electric water heater over the winter, and I've been using that to test the charger. I installed a 200 watt element in it, so it takes a while to heat the water significantly - about 3-4 hours. 200 watts at 12 VDC is about 18 amps - a fairly good load on a small system like ours - but the charger keeps up with it no problem. I think this is going to make our off-grid camping much more comfortable. I considered the Renogy, which is cheaper and higher output. I decided on the Victron, partly based on reviews, partly on reputation, but mostly on physical dimensions. The installation was easy - the hardest part was running the 6 AWG wire to the starter battery. The unit gets a bit hot in use, but not dangerously so. I've installed a couple of 80mm fans on a temperature controller above the charger to cool it down. I'm not sure I needed to do that, but it provides peace of mind. The unit seems very rugged, and the Victron app is very convenient for monitoring the system as I drive, Overall, I highly recommend this unit.

Easy install and works great as it should. Crazy that there is no VW Networking with it and it gets crazy hot even tho there is nothing around, probably should install an extra fan.

Super produit rien à dire

Ottimo prodotto funziona egregiamente anche l'app e semplice e funzionale

Excellent produit facile d’utilisation et d’installation

These are the gold standard for marine use DC-DC chargers. Easy to install, easy to set up, works really well, and well supported by the manufacturer.

Se usa principalmente en vehículos, autocaravanas, barcos o sistemas de baterías duales donde la batería de servicio necesita cargarse de forma eficiente sin afectar negativamente al alternador o a la batería principal.
