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.

And does it work when the leisures and the starter share the body of the van as negative/earth?** A: Yes this work with a smart alternator And work when the leisures and the starter share the body of the van as negative/earth?" **Q: There is no green remote plug to remove per the instructions when setting up. Is this right ?** A: On the one I received, the remote plug was present but fitted INSIDE the blue casing. I believe that with this design, you loosen the screws and remove the wire loop across the terminals of the remote, rather than remove the whole plug. **Q: Will the device charge in both directions (charge leisure battery from alternator but also charge vehicle battery from shore power)?** A: No. The Tr Smart has no connection to the grid and cannot handle grid voltage. Also, in order to protect the starter battery from being drained, when the alternator is not running, the Orions disconnect from the starter battery circuit. Probably safer to get a second, cheaper, mains-powered lead-acid battery trickle charger, which only gets powered up when you connect to the grid / shore power, and keep it connected directly to your starter battery. A trickle charger would not raise the starter battery voltage high enough to activate the Orion so charging can only take place where it's needed. Many people setting up a vehicle system also include a more powerful mains-powered battery charger/power supply for their on-board leisure battery and DC circuits, when connected to the grid. With any apologies due for stating the obvious, battery to battery chargers are for connecting to the starter battery and the circuit/battery to be powered, only, not to the alternator. The Victron web page, data sheets and videos for the Orion series give full info. All the best for your installation. **Q: Can this trickle charge a lead acid starter battery from a LiFePo leisure battery when the van is not being used? (Leisure is solar charged)** A: You can either charge a Lifepo4 battery or a Lead acid from solar panels you can not charge both at the same time or use the Lifepo4 to charge the Lead acid with this. This unit is a solar charge controller only. (ie the solar panels are connected to it and in turn the unit is connected to your battery to charge) The unit must be set up to charge as either Lithium or Lead acid ## Customer Reviews ### ⭐⭐⭐⭐⭐ Worked with Victron for over 30 years, Great.
