While your vehicle's alternator prioritizes your starting battery, this unit will allow your solar system to charge your service battery first it's the smart way to keep yourself fully charged and off grid longer and with multi stage charging and multi chemistry functionality, renogy's dc to dc mppt charger has you covered whether you're using flooded,.gel,.agm, or.lithium batteries. With rj45 communication port featured, you can unlock monitoring features exclusively using the bt 2 bluetooth module.and renogy dc home app, control and monitor the device remotely through your phone in real time.

Review: It was so easy/user friendly regarding functionality, installation, and everything else that’s important! The little monitor would always tell me accurate readings in the year+ that it was installed in to my camper van.
Review: Other than a issue with a TAX invoice as in they do not supply one a major pain In Australia if you want to claim the unit as a Business expense as is what i wanted to do. The unit is by far the best one i have tested so far. It does not just charge and cut off it also supplies power to the connected devices so as not to run the battery down when the battery is full and the sun is still shinning. So if you don't need to right this off TAX wise i would recommend it. So 5 stars for the Item 1 start for the seller.

## Questions & Answers

**Q: Solar input is still limited to 25v on these?  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.

### ⭐⭐⭐⭐⭐ Review
*by J***U on 22 December 2025*

I rarely leave reviews and in most cases only when I am really annoyed by a product. But this unit is really great at a very resonable price! Works very well, is compact, and has many great features that only a combined dual (solar and alternator) charger can provide. For example charging my starter battery when the solar battery is full. I think I had a small parasitic drain on the van which caused the battery to be empty after a few weeks of not driving. With the renogy charger that is no longer a problem. And of course the main function to support dual charging is also great. I specifically used the smaller version (30A) to limit stress on the alternator . That is probably the only missing feature I can think of: configure the max draw from the alternator in the app. But with the 30A version that is not really a problem. And I anyway only have 400W of solar, so 30A is fine.
