I have a 200 watt solar array connected to the solar input as well as the vehicle smart alternator input. The (2) 100 Ah AGM batteries stay charged through this device to where I never have to plug in my trailer to the house to charge my batteries. What I like about this product is if itโ€™s cloudy and Iโ€™m using power then the vehicle will charge the batteries as Iโ€™m driving from job to job or I can start the truck for a few minutes and get a charge. This device also prevents voltage feeding back to the vehicle from my trailer batteries as it would if it were connected straight to the battery output from the truck. It also prevents overcharging of the batteries, extending the life. Lastly, the ability to change battery types on this device makes it great to use for different battery chemical types. The price is a little high but it does exactly what I need in just one device. Review: Does what it says it does so far. Get the Bluetooth adaptor. - Not sure why this product is so unusual in the market. Having both vehicle power input AND a solar power input is very helpful to say the least! Came with some nice accessories like terminals and a nice ALN fuse holder. Hooked up easy, does what it says it does. I highly recommend getting the BT2 accessory. I could see that one of the solar panels I bought was defective. I would have not been able to detect that without it. ALSO, I can use the phone app to set a MAX charge current. That is very helpful for when I want to charge my power crate off of a car cigarette lighter socket etc. My project is intended to run a remote office while camping in remote areas. The charger fills a 100Ahr Lithium battery. Inverter is just a little 400w unit. I used a 50A Anderson connector for the vehicle power input and a 30A Power pole for the solar hook up. If I added more solar I would upgrade that. I have a power disconnect switch on the battery to isolate the system when not in use. Enjoy. ## Features - ๐Œ๐ฎ๐ฅ๐ญ๐ข-๐ˆ๐ง๐ฉ๐ฎ๐ญ ๐„๐Ÿ๐Ÿ๐ข๐œ๐ข๐ž๐ง๐œ๐ฒ ๐Œ๐๐๐“ ๐‚๐ก๐š๐ซ๐ ๐ข๐ง๐ : Renogy DC to DC Charger with unique dual charging options.

No upgrade planned? So much for connecting a single 450 watt 48v panel.** A: Another year later the input voltage is, yes, still 25 volt. I was hoping for a 50-75 volt model as well. My space can accommodate 1x 400 watt panel but not 2x 200 watt panels. Bummer. **Q: what is the maximum current it draws from the alternator?.** A: The victron device shows 49 amps charge without solar hooked to it . A few 1000 mile trips and its workin great . Keeps the battleborn batterys at 14.4. **Q: The manual says: "no temperature compensation when charging lithium battery". Why?** A: Lithium Batteries can be damaged if the temperature is too low (less than 32 degrees) when charging them. So you have to either have a heater (or a heat pad) to keep the batteries above temp, or you have to disconnect the charging circuit when the temperature is going to be below 32 degrees. That statement is just giving you a heads-up so that you are aware of the consequences that could occur **Q: Can i use this in an rv trailer by connecting the dc side to the output on the trailers converter, instead of an alternator?** A: Sure you can but won't get a large amount of amps (unless you have a higher amp inverter/Converter) to charge the system.. Just be sure to wire it without a smart alternator which is found on newer cars. ## Customer Reviews ### โญโญโญโญโญ Awesome charger! *by J***. on September 14, 2024* I have a cargo trailer that I use for work with a 2000 watt inverter to run power tool chargers & lights in the trailer.

Get the Bluetooth adaptor. *by S***D on April 25, 2023* Not sure why this product is so unusual in the market. Having both vehicle power input AND a solar power input is very helpful to say the least! Came with some nice accessories like terminals and a nice ALN fuse holder. Hooked up easy, does what it says it does. I highly recommend getting the BT2 accessory. I could see that one of the solar panels I bought was defective. I would have not been able to detect that without it. ALSO, I can use the phone app to set a MAX charge current. That is very helpful for when I want to charge my power crate off of a car cigarette lighter socket etc. My project is intended to run a remote office while camping in remote areas.

I ran on their "Li" profile for my Litime batteries. After a year, my controller started having issues and caused all kinds of chaos with my batteries. Renogy Tech Support told me that their controllers are tuned for their batteries, and anything outside of that must use the "User" profile (Custom). And because of this, Renogy refuses to honor the warranty on my controller.
