BougeRV Li 30A 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

I bought 2 of these inexpensive 10 amp PWM controllers on sale for their portability and lithium charging capabilities to cycle 10 of my 20 -24ah LiFePO4 batteries. I teamed them up with my Elecaenta 75 watt portable folding solar panels and some adapter cables. I am impressed with the features and performance. The only downside I could find is the display can be hard to read under some lighting conditions.I like the ease of adjusting the LiFePO4 output voltage as my lithium batteries vary by recommended charging voltages from 14.4 to 14.6. When it gets towards the end of the charging cycle this controller also maintains the full voltage while gradually decreasing the current output to top off the battery.I have not encountered any error messages on either unit. I have read some reviews claiming the solar input value displayed is not same as the actual solar input value. The note on page 12 of the user manual explains the solar charging voltage displayed will be the same as the battery voltage in PWM mode. The true solar voltage is displayed when not charging (end of the charging cycle).

App works great I can see all the info I need on app. Easy install

BougeRV Li 30amp PWM Solar Charge Controller. I needed to replace my old solar charge controller with a unit that would fully charge a LiFePO4 battery. This charger had decent reviews, and the price was very good at the time of purchase. This controller is quite simple to set up. It allows you to set a range of options that include all the current battery types and provide display information that is easy to understand with a welcome backlight. I was hoping that I could find a controller that had Bluetooth connectivity, and this new unit has that. You will need to download the app and follow the instructions in the app. I monitored my charge from about 50 feet away and was able to connect and receive progress information without errors.What I like: Easy to set up. The Bluetooth connection is helpful. I also like that the unit allows for a wide range of battery types and particularly for the LiFePO4 type batteries.Dislikes: I did not remove a star because these are not operational issues. There are a few things that I found could be improved but did not hinder the operation. One is the connector hole for the wire is small. 30 Amp calls for at least 12 AWG wire but anyone wanting to extend the cabling 20 feet or so away from their panels will want something larger. I like to have at least 10 AWG wires. The connector holes may not be large enough to accommodate 10 AWG. However, BougeRV provides small spade connectors. They are rather thin gauge. When installed, the plastic insulator will not fit all the way into the opening. The plastic must be crushed to reduce the size. Another thing is the confusing picture of the 30 Amp controller in the manual. The 30 Amp unit picture shows a set of heat cooling fins on the bottom. However, there are no fins. This makes one believe that they did not receive the 30 Amp unit. The model number on the unit says 30 Amp and I confirmed with customer service that this was the correct unit. It just no longer has cooling fins.Overall, this is a very good controller for the price, and yes, I would recommend it.

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-GirdBeen 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.

trying to save money sometimes does not work...this 20amp pwm by bougerv failed in 2 months with daily usethis was hooked on a single 150watt solar panel..it was working at first for daily use but then suddenly stopped accepting ampsunable to send it back per amazon...trying to see if I can get a refundsave a couple more dollars and get a mppt charge controller

I actually have two of these and they have been working fine charging the Lifepo4 batteries. I have two because I have solar panels in two different locations which are far apart.

This is a pwm charge controller, so you have to remember they work best with short runs of cord (10-20 ft), and with panels in parallel. Very easy to read and set without directions. This is ideal for a portable setup, rv, trailer, or something directly outside your window. Running 4 100 watt panels in parallel you will close in on 300 w atts, but don't expect too much more. Depends on the panel too. I use Newpowa which typically run about 70%. HARBOR FREIGHT, Bouge RV and HQST panels have about the best output in the 100-watt category, but they are a little bit bigger. This is my fifth one of the lithium pwm series.
