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 years2. 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.

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

Really worth the money

I’m a long term user of victron - this is my second install - I would always recommend. No issues and a good support community

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.

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.

easy to install, works as it should.
