  • Let me tell you what BougeRV did to me!
Style: 40A MPPT White
This BougeRV Co. really got me good. Contacted them about the Remote Monitor, the RM-6, the LCD display was cracked. Had this big arrow across it, definitely was not going to work. Discussed with them the problem, told them I had looked at getting a replacement but sellers wanted twice or three times the worth. Plus ridiculous shipping equal to cost. It retails for $11, from China supplier that makes it. I had rec'd the 40A MPPT and didn't have time to set the system up. Never opened the box, put it on the shelf. Finally found some time and opened it up to see what I had. Damn, the monitor is busted. Been there the whole time and I never checked it out. Return time had ended and I was up a creek. I contacted them to see if I could get another RM-6 for a reasonable cost. They had me take photos of it, one of the back with the funny looking digital sticker and bar code. They got back to me, said it would take 10 to 15 days to ship. Then they notified me of the cost.....nothing. They replaced the RM-6 for free. Not even shipping. Asked me if that was ok.....well, as we say in Texas....Hell Yeah! I'm impressed with BougeRV's commitment to their products and customer service. Very impressive. I inquired about their manufacturing providing them with the 60A MPPT. In doing research I found the very same MPPT's under another name and found the 60A. Was just a little more. Recently, found the 60A listed on AMZ under the other name, but ouch! The price was way higher. BougeRV got back to me concerning the 60A, they do not sell it as of yet, but will. They will notify me when they carry it. Reason I chose BougeRV MPPT was I liked the stand alone ability, no stupid extra WiFi Dongle to buy. No need to download an App to work it. No extra downloads to a computer to operate the perimeters, just a simple easy to use Remote Monitor. Hell, you don't even need that to set it up and run in factory mode. Keep It Simple.....Stupid! Simple is better. How many of you have fought one of those darned HE washing machines with some Smart Mode junk? Darned thing takes two hours, doesn't use enough water, and your clothes are still dirty. Yup! I like simple. Do your research....then decide. Cost comparison and customer service and satisfaction knocked it out of the park. ... show more

  • Simple to install and use.
Style: 40A MPPT Yellow
This MPPT charge controller is very simple, but does the job. It is a rebranded Helios MS-4840N, and that model is what shows up for the bluetooth connection. I just hooked it up a day ago, and it's been mostly cloudy, so I'll update this review once there's been more sun. There was some sun for an hour or two early this morning around 9am, and it recorded a max charge power of 207 watts into a 50% discharged battery from a 400 watt series pv string angled straight south. Not bad for 9am, since the sun was at a severe angle off perpendicular from the panels. Pros: The case is all aluminum and solid. Integral heat sink fins on the back. This is a newer model compared to the Renogy and Rich solar clones and has better specs. Up to 150V PV input, so you can put 7 typical 100W panels in series. Most others can only do 100v which limits you to 4 panels in series. This unit will also work with 12, 24, 36, and 48v batteries, so you can get more watt-hour capacity without huge power cables, and max out your pv input to 2400w with 48v battery. Most other units in this price range can only work with 12/24v. I'm getting decent range with the bluetooth connection. I am just in range from inside my house, with the controller inside my garage over 40 feet away. No problem connecting with the app when within the stated range. The 4 wire terminals for pv input and battery output easily held 10AWG wire and I believe can take up to 6AWG. The voltage reading is pretty accurate. If you're seeing a big difference from the display to whats at the battery terminals, you may be using undersized or too long cables. Cons: Glass face plate looks great, but seems a bit odd considering how rugged the rest of this is, being a solid piece of metal. The manual states "baclit lcd display", it's a simple 4 digit 7-segment lcd that displays either battery volts, SOC, temp, and error codes. There's just one button on the front. You can cycle through those 4 values, or long press to change some settings, but you'll need to use the app to change most settings. The SOC% is based on the battery voltage for the battery type selected. The app will show near real-time stats, such as PV volts, battery volts and charging amps while you're connected, but this unit does minimal data logging. It only reports ONE data point per day of the following parameters - max charge power, max and min batt voltage, cumulative charge power. It doesn't report anything for discharge as this unit has no load terminals and therefore no shunt to monitor them. Also note, a day to this unit is marked by pv input, not a calendar, so if the pv input drops out it will count that as night and reconnecting will start a new day. Also, I don't see any indication of battery charge mode, bulk, absorption, float, etc. Overall, it's a great unit for the price. Perfect for an rv to mount in a storage bay where you won't need to look at it, because once it's setup, you won't have to check on it. Or use the app if you want to check. If you want to log a bunch of data, get a battery shunt logger. ... show more

  • Better than the richsolar one
Style: 40A MPPT Yellow
I like the fact that Bluetooth is built in, plus it has a decent range of about 20ft. The unit has worked very well so far using 4x100w panels and two 22v 100ah batteries to power a well pump and various accessories. I'm not using the load center in the unit since at 24v it cannot handle the 3kw needed to operate the pump and accessories. My only concern is accuracy. At times it records the batteries at 4v which is impossible. It also records charge power at over 400w sometimes, which is also impossible or at least very optimistic. Also temperature seems off, and I have no way of changing the reading from Celsius to Fahrenheit via the app or any other way I can see. That's a bit frustrating. Other than that, I think it's better than the rich solar units I've been using or the victron I used to have. Also cheaper if you catch it on sale. ... show more

  • Gets Hot when it has to limit charging power!
Style: 40A MPPT Yellow
Gets Hot when its has to limit charging power. Hot hot, mounted inside a 4o F garage, it managed to get up to 122 F as read by the embedded temperature sensor. I have it hooked to a 1200 Watt solar array, sweet spot around 60V, and 24V battery pack. I had to change the mounting, from flat to the wall, to adding about an inch airgap, to allow the unit to cool a little better. The real question is: 'how can a unit that claims 99.5% efficiency get so hot from that 0.5% of energy it consumes?'. Overall, a solid device, if you don't run it near its spec. The android app is clumsy, but doable, and the unit itself only consumes about 10 mA at 26V (300 mWatt) so should work well for a smaller battery pack. i'm upgrading to a 60A device, as i don't feel good about running this thing at spec for the next ten+ years. Oh, did i mention that the green LED's on the unit are absurdly bright! ... :) ... show more
