This will be my first installment of a review on the EPEVER Tracer 4210AN (May 14th, 2018).
I installed this controller, along with the MT50 remote display, on my 23 foot travel trailer during the last month. I am using it with two Renogy 100 watt panels and two series 24 flooded cell batteries. I have wired the panels in series and the 12 volt batteries are in parallel.
My wife and I just returned from a 9 day trip with one day of boondocking. Although this is a very limited test of the system I wanted to report my results. I will update this review a few times as we get more experience with the system.
I am VERY pleased with the system so far. It is exceeding my expectations for all conditions that I have had a chance to actually try. Also, the physical appearance and quality of manufacture of the system seems very good, especially for the price.
We are very thrifty electricity consumers due to our many years of boating. My normal budget for a day is less than 40 amp-hours. This is mainly water-pump, control circuits for the refrigerator and water heater, lighting and phone charging. All lighting in our trailer is LED.
In this situation we are only down 20 or 30 of our 150 or so amp hours when the sun comes up (16%). I point this out, because I was delighted to see 7 to 8 amps at 8:30 in the morning. I have read reviews stating disappointment in low amp output and really wonder at the state of charge of their batteries at that time and their system topology. I have seen the 4210AN producing as much as three times the current into the batteries as was coming out of the PV array. This is why I chose a series configuration for the pv array. Early in the morning with low sun and clouds I still get output!
I know the above paragraph is a little wordy and covers a lot of ground but I think the topic is a little more complicated than many consider it to be. In summary, my early impression of the 42110AN is that it is a great product for the price.

MT-50 Remote Meter Display

Remote Temperature Sensor(TS-R)

Battery type selection: lead-acid (Gel, Sealed, Flooded) and Lithium, voltage parameters can be set on the controller
(For the BCV, FCV, LVD, and LVR, users can modify them on the local controller when the battery type is "USE.")
How to program for Lithium Battery？
- Set the battery type via the LCD (LiFePO4(4S/ 8S) and Li(NiCoMn)O2 (3S/6S/7S))
- Via PC (Accessories needed：RS485),
- Via phone APP (Accessories needed：Ebox-Wifi or Ebox-Blue)
Warm tips：
Step: Connect the system in the order of 1.battery-->2. load-->3.PV array, and disconnect the system in the reverse order 3. 2. 1.
- NEVER connect the soalr panel array to the controller Without/ Before a Battery.
- Battery must be connected first !!!
- DO NOT connect any inverter/ wind/Alternator or Charger into the charge controller!
- If the remote temperature sensor is not connected to the controller,, the default setting for battery charging or discharging temperature is 25 °C without temperature compensation.
- The wire size is only for reference. If there is a long distance between the PV array and the controller or between the controller and the battery, larger wires can be used to reduce the voltage drop and improve performance.

Works as expected. Great price and simple to install. Love the remote monitor!
Reviewed in the United States on June 15, 2018
So far, I'm very happy with this product. My setup is primarily to power my home network gear (internet, wifi, switch) in the event of an outage. I have two 12v batteries and a Xantrex Freedom Xi (1000W) pure sine wave inverter. I did read some other reviews and made sure to use 2 gauge wire from the batteries to the inverter. The charge controller stays cool and keeps everything running well. Someone mentioned low amperage output but what I noticed was that the amperage output only displays what is really being used. Example: If the inverter is off, the charge controller shows a very low amp value, but as soon as I enable a heavy load, it displays the expected higher amperage. I will attach two pictures, one showing 10 amps and another with 9.7 amps output.My only complaint and it's very minor is that it doesn't have a place to attach a ground wire. I have a ground wire looped through one of the mounting screw holes, not the best, but it's functional and I know it's grounded.

I just purchased a new RV and needed to add solar charging as I had installed on my old RV.
I was a little skeptical when I purchased this Solar Charge controller since I usually try to stay with US built products. I most always get better service and quality from US companies and a better warranty. After looking at the cost differences between the China built product and what I paid for my first solar controller "US product" I figured what the heck! I'll give it a try. And I gotta tell ya, I am impressed with this MPPT 30 amp charger! I roof installed the exact same two 7 year old 140 watt solar panels. I actually moved the same (3) 105 amp hour deep cycle batteries I had just purchase for the old RV about 6 months ago to the new RV.(Cheap sob's) only put 1 small deep cycle in the new RV. So I am pretty much comparing apples to apples except for new wiring with the same size 8awg wiring I had in the old rig. The only major component changed was the Solar charge controller as the old one was not designed to be located with a separate monitoring panel and I could not find an ideal location for it. Long story short this EP Ever 30 amp MPPT charge controller charges better than the old one with the same solar panels. The old controller was also and MPPT controller but the best I had ever seen was about 8.5 amps on very low batteries. I have seen as much as 12 amps charging with this new controller with the same (7 year old panels). It steps down through the charge process just as it should and if left on it maintains the batteries properly and also sleeps and wakes up properly once the sun rises just as it should. I do a ton of off grid backwoods or desert camping and as long as it holds up? I will be a happy camper watching the nightly news or a movie without firing up the genny... :-) Only suggestion is make sure you get the NEGATIVE Ground model if you are in the US...
