Rover Boost MPPT Solar Charge Controller 10A 36V/48V for Golf Carts

This has got to be the best invention out there for solar. I placed a 100 watt 12v solar panel on the roof of my 36 volt golfcart with 3 12v lithium batteries. Using 10 gauge DC wire I hooked everything up per instructions and the controller immediately started charging. It's been 3 weeks now and I haven't had to use my charger once. This Boost Controller keeps my batteries between 38 and 39 volts when I'm not using my cart. Set up was easy, anyone could co it. I highly recommend this if you have limited room for solar panels.

I put 66v into it, to charge a 48v lifepo4 battery on a golf cart , and it didn't work at all.

Using two units each with a 395 watt solar panel to maintain and charge 10 kwh of 48 volt batterys which use around 40% most days. Bigger batteries than really designed for but it's doing its job maintaining it. Charges around twelve amps with two units.

I haven’t got it to work yet

I purchased this to charge the golf cart batteries with my solar panel on top and it worked perfectly. Very easy to set up. The digital display on the phone is cool. It is Bluetooth. I’ll definitely be getting more of these for other applications.

This thing works great. I have a solar panel that only produces 30 bolts on a good day and this unit easily boosts the power to charge my golf cart. It seems to peak at 53 volts, but that’s plenty. I wish this company would just give us Bluetooth though. It’s not like that’s some super secret technology. Why not just install it in the factory? Point is Bluetooth is very necessary so just also get the BT2 otherwise you’re just hoping it works without seeing the settings. Good value for sure

Everything seemed to work fine for 10 months and then last month nothing, had solar power coming in but nothing coming out. Replaced with cheaper unit from a different company it seems to be doing fine

I bought this, installed it new. (I am an electrician and have an idea what I'm doing), it has never worked. 20v coming in from the charger, no voltage coming out. The switches do nothing either. Waited on hold about 20 minutes to talk to someone, they emailed me and wanted more info. I replied and gave it to them and the 7 days later, still had no response. I called, was on hold for 30 minutes, then had the same run around. They wanted me to pay to ship it back, they would test it and then send me a new one and I would have to pay shipping again. Crappy warranty system, horrible customer service.
