EPEVERMPPT Solar Charge Controller 30 amp 12V 24V Auto, 30A Solar Charge Controller Max 100V Input Negative Grounded Solar Reulator fit for Lead-Acid and Lithium Batteries and Support Batterless Run

I bought the 4210AN for my camper solar and it works great. However, I needed to change the settings to Lifepo4 and the manual appears to give conflicting information. I searched the internet and just got more confused. I bought the PC cable and downloaded the software. I couldn't get it to work. In frustration I contacted tech support and they promptly explained what I needed to do and how to do it. Fantastic!Three things to remember:1. If you have the CC-USB-RS485-150U cable, you need to use the CH343 driver and it will show up as that in the Port Settings in Device Manager.. When you go to set the baud rate to 115000, you will not see a checkbox for "RS485" that the installation instructions say you need to check. The driver for this cable doesn't have the box and doesn't need it. The other (and older) cables use a different driver and *do* need that box checked.2. When you get the software setup and you are ready to click "Start Monitoring", don't. It probably won't work. After setting up the COM port in the software, you need to restart the program. From there, it works great and you can tailor the configs to your needs.3. When using only the front panel to select the battery:A. Battery type " USER" is preprogrammed for 12V Lifepo4 and is the same as "F04" (12 4 cells.)B. Battery type "F08" is the standard settings for the 24V Lifepo4 battery (8 cells).Finally, you might want to tweak some of the settings via the software or MT50 but the presets are good starters and likely won't need tweaking if you have a good BMS in the battery. But changing parameters isn't all that hard once you get the cable setup.

I'm one of those folks that usually write a one or two word review... Not this time. I received the charge controller and installed it with no issues. A day or so later it appeared to have failed... I was wrong in my assumption, actually, one of the radios that the system runs had failed, to a short internally. The Tracer 4210AN detected the short without blowing any fuses and shut down the supply to the load and presented an alarm indication. I thought that the Tracer had failed and contacted their tech support. I got a super fast response that put me on the right track to correcting my error along with specific settings for my battery system. Wow! I highly recommend these folks! Good value, Fast shipping, great product and the best tech support ! No, I have not been compensated for this review, I just think superior service needs to be recognized.

I have a Lance truck camper, one agm 105ah battery and a 100watt solar panel. I've camped over 365 days with 90% off grid and have never had an issue. I also have the mt50 remote which enabled me to mount the charger closer to the battery. Very pleased.

Seems to be a very well made, and high quality solar charge controller. The only mechanical issue I encountered, was the head size of the terminal screws. They are on the small side. Try #1 Phillips, and don't over torque them; but do check them often to be sure they remain snug.The manual was a bit confusing, for me, but I take responsibility for that due to my experience level.Make sure to read, and understand the manual. What confused me was the charts showing rated charge power.I ordered the 30 Amp model. I have a 12 volt system. The chart shows a rated charge power of 390 watts at 12 volts, with a max pv array power of 580 watts for a 12 volt system. Per their chart, I didn't think it would take 30 Amps, but apparently it will, with the appropriate input voltage from the solar panels, and the voltage accepted by the battery. The day I tested it, we had partial sunlight. My panels are rated at 200 watts, and 17 volts, and about 11.76 Amps. I'm using two of these 200 watt panels (400 watts). When I read the Manual, and it said the rated charge power was 390 watts, I thought I had a possible problem, but the actual test showed the controller handled my setup. EPEVER Manual says the controller will throttle down, if necessary to protect the controller. The day I tested it; the controller showed 20 volts in from the panels, and 15.5 Amps out to the battery, at varying voltage, around 14 volts, on the battery end. I am waiting for a full sunny day to compare this EPEVER 30 Amp MPPT, to my old HQST 30 Amp PWM. I thought I was getting up to 20 Amps out from the older HQST PWM controller. Will need a full sun day, to try them both again, and compare the results. reviewed by allstar - 1-23-2023

works like factory originals

The controller works great but the terminal for the PV broke and would not tighten the cable. Getting support is a run around and they do not offer any replacement except to send me a terminal that I have to solder myself which I have no idea how to do and nothing found yet on the internet. Giving a 3 star for this reason other than the product works as expected.

I recently installed the 30amp EPEVER solar charge controller on my RV. The "solar on the side" port now feeds this EPEVER solar charge controller. I have 3 200 watt portable solar panels that I can plug into the port and charge my house batteries. Because it is a MPPT controller I can run my panels in series (75v, 200watt) or parallel (25v 600 watt).I really like the interface and this unit gives the most Battery variations I have seen on any solar charge controller. I use LiFePo3 batteries and I found that this unit was very easy to install and setup. I was running my panels after 30 minute install.I recommend this product as a good MPPT unit.
