A**.
Worked with Victron for over 30 years, Great. I bought the Isolated.
Victron Energy Orion-Tr Smart DC to DC Charger (Bluetooth) - 12/12-Volt 18 amp 220-Watt - Battery Charger for Dual Battery Systems - Isolated Does not come with BT antenna connection. As I said long very good experience with Victron equipment, mostly battery chargers. Bought the 100V 30 amp 12/24-Volt when I started in Solar, great kit, tried all sorts of different types. Victron comes out tops. Should have stuck with Victron. This DC-DC charger is a little difficult to setup, rookie should be good with the setup as long as they check & double check. Ensure all crimps are good (Some of the crimps are poor, My 12V setup is 2 by 100 AH lead acid batteries & 2 by 130AH leisure batteries, supplied by a small mains homemade charger using a 240/15V Tx, 50A Full-wave rectifier with 2 10A Germanium blocking diodes to block any spikes & earth faults. Also have another mains auto charger as backup. The 100A LA batteries are connected to the Victron MMPT 30 / 12/24 solar supplied by 2by 35V max V, 340W panels. (wish I could afford to get another 2 of these) Output on full moon lit night was up to 50W. I had a Renogy DC-DC 12 20A charger fitted, NFG. Fitted the Victron 18 DC-DC . Charging a Moseworth 12V 200AH Lifepo4 (Best battery buy on reviews for price & support at the time) I have set this up to keep a constant charge of 13.4V, Now changed to 14V, it is holding the charge well, I run outside lights, garage 12 volt lighting & PTC heating for winter & comfort, compared to the Ren this is keeping the charge stable. took all charging off the Lifepo4 & then switched on the Victron DC-DC on magic. I have a YZPOWER 14.6V 20A LiFePO4 charger as backup connected to the Lifepo4 in parallel with the Victron, works well with both switched on both work together. I have a test discharger 12V 15A, When I switch everything on the Ferrite core Dc meter shows full charge current on the 18A charger. There were 5 massive trees blocking sunlight, Lady at the back on the south end of house has removed them so I would say 200% more sunlight, if not more, winter will tell. Comments: 1. Victron is expensive, you pay for what you get. Wish I could afford the Victron batteries. Life of LA 5 years compared to Lifpo4 8 to 10 years 2. If you can go for Lifpo4 batteries, LA do not last, there are ways to regenerate LA batteries, look it up, time consuming as in 4 to 5 days, difficult, need new acid (UK you need a licence) 3. Will either sell or use the Ren charger on my system in the study. 4. Reason for 4 stars, Never give 5 till proved. 5. Pity it does not have the blue tooth socket. It is working VERY well. You pay for what you get. 5 stars. Brilliant. Best buy I made.

Don’t always do what it says in the box…
Doesn’t do what it said on the instructions - thank goodness. The wrong information sheet was provided in the box. Apart from that all went well and the product appears to do what it should. Time will tell….

Ideal
Added to my other victron chargers recently fitted in motorhome to replace a redarc unit which didn't have a specific AGM setting and no remote on/off. The tr-smart complements the other 240V and solar chargers, completing the suite and all having Bluetooth to an app. Install and setup was easy

Excellent product
Victron are excellent quality products. Usually have a 5 year guarantee and are excellent. You pay a little more but you get the best quality products. I’m using my purchase on my boat so that my starter battery can charge my two house batteries in parallel.

Excellent piece of kit
Bought this to add to my lithium/solar setup. Easy to setup ^ use through the Victron App, though I found you will need a square crimp for the wire lugs to fit into the terminals.

Failed after 6 weeks and left us without charging whilst wild camping
The unit has failed after just 6 weeks and will no longer charge the leisure battery. Everything has been tried on both the app set up and from the community pages. We mainly camp off grid so had to get a replacement whilst on our travels . Very disappointing and now having passed the return window it’s not clear how I complain to the supplier, Amazon EU. Arghhhh!

Great Solution for Charging Auxiliary Batteries Without Draining the Starting Batteries
I bought this Victron Orion-Tr Smart DC-to-DC charger to charge auxiliary batteries I was installing on my truck. I specifically did not want the auxiliary batteries directly connected to my starting batteries, for obvious reasons, and this charger did exactly what I needed. It’s not the highest-output charger available, but for my application the 18 amps is enough, and it charges my auxiliary batteries just fine. The built-in engine shutdown detection is especially useful because it can detect when the engine is running by monitoring the voltage coming from the starting battery and alternator. When the engine is running and the alternator raises the voltage, the charger can charge the auxiliary batteries, and when the engine shuts down, it stops charging so it doesn’t drain the starting batteries. Victron is a brand I’ve had very good experience with, and the Bluetooth connection to the VictronConnect app makes it easy to configure the charger and monitor what’s going on in real time. For my purposes, this was exactly the right solution: reliable, isolated charging for my auxiliary battery bank without risking my truck’s starting batteries. Five stars.

Perfekt für meine Vorgaben
Victron typisch macht was es soll. App funktioniert perfekt. Seit ein paar Wochen als Ladergerät für 100Ah Lifepo in Betrieb. Kompressorkühlbox, Luftkompressor arbeiten tadellos

Veramente completo e di qualità.
Ho installato e configurato il caricatore Orion TR-Smart da 18A isolato sulla mia autovettura dotata di alternatore classico da 120A, per caricare una batteria Lifepo4 ausiliaria da 50Ah. La configurazione tramite l'app ufficiale è abbastanza intuitiva, fatta eccezione per alcuni parametri relativi all'alternatore, per i quali ho dovuto consultare alcuni video youtube. Dopo aver compreso il significato di alcune voci, ci si rende conto che questo caricatore non è un giocattolo, ma un prodotto professionale. Una volta impostato tutto come desideravo, il caricatore funziona alla grande. Entra in funzione e porta la batteria alla carica completa in brevissimo tempo. Inoltre, scalda molto meno di quanto temessi. Lo uso da un paio di mesi e per il momento mi ritengo davvero soddisfatto. Siccome sono abbastanza perfezionista, spero che il produttore rilasci in futuro un aggiornamento firmware che consenta anche su questo caricatore di monitorare e regolare l'amperaggio in entrata e in uscita come sulla nuova serie di caricatori XS. Difatti, nel mio caso, limiterei la corrente in uscita a 5 o 10A, così da ridurre un pò il carico sull'alternatore durante la fase di bulk.
