I bought this BougeRV Li 20A PWM Solar Charge Controller for my 12V setup with three 100W panels in parallel, and it's doing the job reliably. It auto-detects 12V or 24V systems automatically (I only run 12V, so that was plug-and-play). No problems handling 300W in full sun—no clipping or getting hot. The backlit display is easy to read and shows PV current, battery voltage, and charging status clearly. It has Bluetooth connectivity with the app for monitoring and control from your phone, which is a nice bonus. There's one USB-A port (2A output) that's handy for charging a phone or small gadget, and the lithium settings work great with my LiFePO4 battery—the recovery feature helps if it gets too low. It doesn't have a load output, but I doubt most people use that anyway. Anyone who knows anything about solar will tell you that MPPT is better than PWM, and that's true. But not every project needs the higher-priced tech. PWM just needs a clear sky and it does the job. Setup was simple, protections seem good, and it's been solid so far. I have several BougeRV products now, and I think they compete well with higher-end items. Good bang for the buck for a basic 12V solar setup.

Review for: BougeRV Li 20A PWM Solar Charge Controller 12V 24V, with Backlit Display, USB Port, Negative Ground Battery Intelligent Regulator for Solar Panels Compatible with LFP, AGM, SLD, FLA, for RV, Off-Gird Been using this charger on our pop up camper since April 2023. It works well, keeps our battery charged from solar while camping. I have a voltage booster on a 12V charge line from the truck when pulling and that works well also. Both are connected to the charger in parallel with a 10 amp diode to isolate the booster line, requiring me to be aware not to connect solar and the truck at the same time (hard to do in practice and probably would not matter anyway). Unlike another charger I have (ECO-WORTHY 12V 20A DC to DC MPPT), this charger will charge in low sunlight. I would rather get a charge of 0.2 amp on a cloudy day instead of zero like the Eco-Worthy does. Only complaint is the display is on as long as the charger is connected to a battery. That is not drain much from the battery but we leave the camper unused for a month or so (still have to work unfortunately) and I don't like the trickle discharge. Have not actually seen a problem with this, but still would like the display to turn off when not needed. Suppose I could install a switch... Should issues arise with this charger I will update this review.

I've had 3 different solar charge controllers and this one is by far the best made quality. It works exactly as described and the manual is easy to understand. Very sturdy construction. I think I'm going to replace all of the other controllers I have with these. Update: I bought another one of these to go into a portable battery case and it failed during testing. I contacted BougeRV about it, they sent over some troubleshooting steps and when it was deemed defective they replaced it. Stuff breaks, but how the manufacture deals with it is important. Full marks for how this was handled. Once again I recommend these devices and the company.

This would be a great controller if it actually didn't overcharge lifepO4 batteries. As soon as the battery is full, it starts clicking, crackling, heating up super fast and the voltage sky rockets, the amps plummet and it fries the battery, you can smell it. Very dangerous as it doesn't stop, you have to emergency disconnect. Even the bluetooth app shows it. Tried reducing the max charging voltage to way less than what it's supposed to via the app but the problem still happens. What a shame.
