Essential Features
- RV dedicated MPPT controller: Negative ground designed for RV. Better protection of LCD readings while protecting the controller, and modification of controller parameters is supported.
- Charge Smarter: Due to an advanced digital power technology, the circuiit energy conversion efficiency is as high as 98%.Automatically detects 12V or 24V DC system voltages. Compatible with various Deep Cycle battery options: Sealed, Gel, Flooded, and Lithium.
- Efficient MPPT&Weather resistance: Rated charging current:40A Operating temperature:-35℃～+45℃. It has a big heatsink on the back, but even in 45 degree weather it hasn’t become warm, which is a great indicator of its high efficiency. The charger is efficient in charging your battery. It helps that battery can be charged up quickly, even when the weather isn’t ideal (ie cloudy rainy days).
- Electronic protection: Electronic protection against reverse polarity, overcharging, over-discharging, overload, short-circuiting, and reverse current.
- Electrical Parameters: System voltage:12V/24V Auto Battery voltage:9V～35V Wire specifications:20-6AWG Size:183*127*65mm Max.PV input power:520W/12V&1040W/24V

Watch out for calibration of the unit you receive.I have 2 units of the same kind (40A) from the same seller. One calibrated correctly another not so much. That not so much thinks that voltage is 14.2V when in reality it is 14.4V. This causes issues with properly finishing loading of the LiFePo4 bank (BMS steps in). The remote monitor is displaying battery capacity for LiFePo4 way off (like it shows 49% for depleted battery and 100% for little loaded one). There is no user setting for that… Also there in no backlit for that remote I can find. So I rely on another monitor for battery capacity. MPPT is working but slow not sure this is due to the panels reactance time or internal logic. When reaching powers around 300Watts the unit heats up close to 22C above ambient. I think it needs cooling in hot climates and bigger powers. Super positive features is it will not get damaged when battery is disconnected (or connected after panels) and it will still output 14.4V even with no battery. Manual is well written and unit is very simple to understand. The modeI got did not have load disconnect on overload or depletion of the battery but in reality this is what BMS is for. The unit is relatively compact. I say ideal for small RV B class or van conversion with up to 4 panels (4 different models cover from 260W 12V battery bank till 1320W @ 24V battery bank).

Detecting 24 volt systems seems a matter of luck, but otherwise a nice unitThe first time I connected it to my 24 volt batteries, it decided that it was a 12 volt system (it shows on the display), overcharged to 25.4 volts, and refused to let the panels charge.While I could change Battery Type from the remote panel, I could not specify that the batteries were 24 volt.A support request on the BougeRV website was not answered by the next day, and after disconnecting it, I reconnected it, and this time it detected it as a 24 volt system, and started charging. I didn’t do anything different, but now it works…The unit appears well-built, and now that it’s going, I hope it will continue working correctly.UPDATE: Tech support did contact me by email, but their message ended up in my spam folder, so I didn’t see it for a couple of weeks. They asked for my order number, which I gave them and I am awaiting their response.The unit has been working well for a couple of weeks, now.The remote display showing how many Amps, Watts and AmpHours the solar panels are putting out is helpful, as I had no monitor for that with my previous controller.

Does What They SayI bought the 40-Amp MPPT Solar Charge Controller to replace the PWM controller in my motorhome. This unit facilitated an easy upgrade and produced immediate improvement in solar charge efficiency. My only complaint is that the wire lead for the LCD display is too short and there is no extension cable available. However, this issue is easily overcome by cutting the existing cable and adding RJ-11 connector so that a telephone extension cable can provide any longer length.

Almost worth itThis product would be ideal if it had one important feature; buttons to actually make changes in the settings. One button is available and it only allows you to scroll through, you can’t change anything.Not sure why it’s made like this..It’s ok to charge my two 12v 100A battery bank.I would say; try one and see if it works for you, as it does give my batteries a good charge. Just don’t let your batteries reach below 11v, or you will get an error from it. And I don’t think it charges above 14v from the solar panels. Will do more test and update.Hope this helps, God bless…

Works great — fine technical supportTechnical support was quick to respond to my questions. Product is up and running and working flawlessly. It easily recognizes the different panels. I have a large 250 watt 24 volt panel on the back of my pickup which I use when hooked to the RV. When NOT hooked to the pickup I use three portable 100 watt 12 volt panels which it recognizes without issue. My batteries are 12 volt lithium which did require input from me on initial set up . I did have some trouble initially because my install was built in and with getting the unit’s connectors to tighten on my multi-strand wire. Changed to solid copper wire and everything is now perfect. I highly recommend if for no other reason the great technical support.

Easy install.Display is simple, perfect for a camper. I put 2x 100 watt Newpowa cells on the roof in series and this charges the 12v system perfectly using mppt. Well worth the money for the MPPT functionality.

Excellent MPPT Charge ControllerThe BougeRV MPPT 40 Amp Solar Charge Controller with Auto Parameter Adjustable LCD Display is really great value for the money. The unit has preset parameters for battery types and also has a user defined parameter settings. The unit is durable and well built. The LCD is not backlit and it does not include temperature sensor otherwise this is great value for the cost. Excellent true MPPT charge controller.

Nice small 20 amp PWM solar charge controllerThe solar charge controller seems to work well. I’ve used it with (2) 100 watt HQST panels in parallel and it seems to put out around 130 watts on a early March day. I think it will probably get a little more on a haze free sunny day. In the photos here, I have it connected to (1) 100 watt HQST panel and it is putting out about 70 watts.I like the fact this came with the ring terminal connectors to connect to it. That was a nice touch. The unit is pretty light and not very thick. The LCD display works well and is easy to ready. My only comment is that I wish I could leave it on the amps display screen, but it returns to the default screen after a few seconds.If in the market for a PWM charge controller, I would buy this one again.

Surprising amount of power available even in low lightThe 40 Amp MPPT version keeps my battery perfectly charged. I have an inverter to supply 120V AC 24×7 at a location where I don’t have power. The remote display comes without any instructions unfortunately. I needed to know what an error code was so I asked tech support for a manual. They responded with instructions how to return the unit, ugh. A manual for the remote is not available online or at AMZN.UPDATE: I notice that the sellers since added the user manual online
