Q:Can this controller work with LiFePO4 lithium battery's
by|Dec 2, 2022

Answer This Question

A:  I build off grid electrical systems every day @solavanbuild. Though this device will charge a lithium battery, I have found that there are other brands that are more user friendly and are able to keep a history over the last 30 days in addition to charging lithium batteries.  I owned this charger and a have since replaced it with a Victron Energy Smart Solar Charge controller.

    A:  Hi Don, Yes, the rover 40 has a lithium option to set as a battery type. Please give us a call at (909) 287-7100. We're open Monday through Friday from 8:30 am to 3 pm PST for assistance.

              Rover 40 AMP is a beast!
              So easy to use, looks great, the load side works perfectly, and screen has a great amount of info! Alot more power when it's cloudy than my renogy 30 amp pwm controller.

                40 Amp Exellence
                I purchased this roughly a year ago as an upgrade to the 30 AMP model this product is durable, easy to install, and when paired with the BT-1 and the Renogy App makes this an essential part of any off grid solar setup. I would recommend this product over and over again. I currently have 500 watts of Renogy roof solar and an optional 400 watts of Renogy suitcase solar

                  MPPT 40
                  Nice product, MPPT seems to work well. LCD interface is intuitive and easy to work with. The Bluetooth interface is less friendly since you have to go thru a web style Interface first. I’d like a more direct approach.

                  Great product paired with the BT-1
                  High quality MPPT Controller. Currently I have it hooked up to (5) 100 watt Renogy Solar panels and (2) 12v Smart Lithium Iron Phosphate 100ah batteries and a 3000 watt Renogy Inverter. I plan on adding (2) more batteries in the future. This system is functioning flawlessly thus far. I am currently running a Instant On Boiler and (3) circulating pumps as whole house heating system. Paired with the BT-1 module it is easily monitored.

                  A good controller which comes with the normal Renogy customer support. A great team who will spend time solving your problems and giving advice. The only fault I can find is the LCD panel should have been back lit as it is on the PWM Voyager. It would have been so much easier to read.

                  Controller good, bluetooth and app terrible
                  The controller was very easy to install and set up for my configuration. Yeah, the connections could be better, but overall, good quality controller for the price. The pairing of the bluetooth using the DC Home app, well you will be questioning if they did any real life testing with it for those that are using it in an RV. I mean you are more than likely to be in a place that has no internet, but yet the first thing the app requires is your location. Hello, I am in a place that has no service. It give s you several errors if you have no service. Also, I tried connecting via bluetooth on Android and IOS, there is a difference, it tends to connect more often with IOS, than Android. Not saying it always connects each time, but more often. Android success is about 1 out of 8 times, and IOS is about 1 out of 5 times. I tried this within 5 feet of the bluetooth module and about 12 feet. Same results. I have a Victron battery monitor and it has always connected via bluetooth each time I opened their app. Improve the pairing and the app and you will have a great product.

                    needs improvement for easier user installation.
                    I like the ease of operation, but feel a need for some improvements for installation. I think the wire clamps for attaching solar panels etc. need to be more substantial and easier to open and close. I would also like to have the labels at the entry points of the individual wires be marked on the front of the controller- it was nearly impossible to see how to line them up with the correct connecting point once the controller was mounted on the wall.
