Rover 40 Amp 12V/24V DC Input MPPTSolar Charge Controller

Absolutely no complaints. Excellent device, good Bluetooth reception, even the app (Android) gives me no trouble whatsoever. No glitches. No problems. No complaints.

This is my second 40A Renogy MPPT Charger, both have 40A been awesome chargers, with a decent user manual, and reliable day and night. the second 40A was purchased so I can run different incoming solar voltages. The two 40A units work in parallel to the battery bank just fine. I just ordered a 20A model for another camper, so I can attest I trust this charger to perform. The phone app itself can be challenging and confusing at times, but overall usable,

Use this with a 300w grid-tie style panel @ ~32v. The MPPT very efficiently converts this to charge our 12v RV battery. I have seen as high as ~30a in direct sunlight with this combo. Installed very close to the battery letting the higher voltage from the pannels go thru the 10gauge wire as long as possible, and then making the battery charge cables 6 gague and as short as possible.

Le rover fonctionne bien MAIS le BT-1 pas du tout. NE SE CONNECTE PAS AVEC L’APPLICATION En attente de Renogy avant de retourner le tout. Après plusieurs tentatives finalement le BT-1 se connecte.

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.
