ordered and was expecting an unused new one. what arrived was not packed in OEM box foam nor plastic bag so it was sliding / floating in the OEM box. product is missing the temperature probe for the battery. the anodizing on the heat sink was scratched away down to bare aluminum where it was clear somebody had mounted this using the mounting screws. the product seems great but I have to give Amazon one stars for sending me what is clearly a used product without proper packaging. review of the solar controller: the product seems like it was designed by the same folks that do other solar controllers as the menu/ button/set up codes seem identical to others that I've used by different manufacturers. this is not a bad thing but just curious. I'm using this with for 4 @ 100 w solar panels. the panels Vm is 25 volts so I wired the panels in a serial/ parallel fashion. what this means is two panels are wired in series. the remaining two panels are also wired in series. then the two serial bundles are wired in parallel. this gives about 50 volts @ 7 amps midday. this translates through the mppt controller to about 26 amps at 13.7 volts a mppt controller can then choose the best voltage/amps for maximum power transfer to the batteries. the terminal lug screws for clamping the solar/battery/load wires s*ck, but others have already mentioned this. A number 2 Phillips screwdriver too easily slips out while tightening so you never get a good bite on the wires.

Very good controller. I have a 12V battery system but use 4 solar panels in series/parallel combination. They output is about 40 Volts. Controller does very good job and has a high efficiency. I like the Blue Tooth module that allows to view all parameters of the charging and also makes it easy to control various settings. Highly recommended.

Excellent unit. The 40amp unit is fanless, so keep ventilation in mind if in a tight space. I just hooked up an old pc fan to the load side and it did the job. My first unit shorted on the solar input terminal side after a few months, but their customer service was top notch and sent a replacement quickly. Would buy again.

I am so impressed by this controller. Most of the negative reviews you read are by people who aren't sure how to configure the unit. In all honesty, I did not try to configure the controller on the unit itself. I found it easiest to use the app. Bottom line... Before installing Rover into my system, the max output from 200watt panels was 160w average. After installing Rover I'm struggling 210w of current from 200w panel. That's about a 25% increase! My panels are exceeding their rating with the use of the Renogy Rover. I use the load output to charge my portable charger which fills at a rate as high as 113 watts without any issues. My portable charger allows me to connect cell phones, camera batteries, power packs, AC devices, etc. The Renogy Rover has helped me to squeeze the most out of my panels. I'm able to keep my lithium battery fully charged, my portable charger ( on the load switch) charged, along with my battery operated devices. Over night levels drop to more than 80% and the next morning within a couple of hours I'm back to 100%. Before this controller, I couldn't get my battery to capacity. It was completely discharging overnight before I woke up and I was completely frustrated with my system. Now that I have the controller everything is running at peak and my electronics run 24/7. At the moment this system is working perfectly. I just added a shunt to get the most accurate metering and couldn't be happier with these results. My suggestion, trust the apparatus and use the app to change from acid to lithium battery. I think that is what is creating a lot of confusion for people. One tip... There is a passcode in the instructions that allows you to make yourself administrator and change the password to something of your liking. After that you can change the settings as needed.
