I have 4 x 100W solar panels to charge two 60Ah 12v LiFePO4 batteries connected in parallel, for my off-the-grid ham radio station.
The EPEVER MPPT Solar Charge Controller, 40A + MT50 meter & remote control was fairly straight forward to install.
I liked the extra large terminals that could accept AWG 6 wiring.
After I got the default password (000000) entry right on the MT50 (you have to actually press the arrow button on all 6 digits to successfully enter the control parameter setup, even though the 000000 password already appears on the line) I set my user parameters for the LiFePO4 batteries; then connected the PV panels, and started charging.
The MPPT really does what it says, and maximizes the charge current depending cloud/sun.
Today started with heavy fog coverage, but I was still getting 6 to 9 amps charge.
One really important point is that this charge controller does not produce any significant RF noise like others do on the HF bands.
However I have wrapped a couple of turns of the pair of wires connecting the charge controller to the PV panels around a ferrite toroid choke ring (mix 31 from Palomar Engineers) to snuff out any RF interference from getting up to the PV panels.
This charge controller looks to be well designed and made, and its MPPT software actually works.
Overall I'm pleased with the way this charge controller performs and think its worth the money compared to other cheap Chinese made ones I've tried but rejected.

SolarEpic 4215BN Solar Charge Controller 40A:Built with advanced power tracking technology to optimize the working of your solar charger system. The controller features a smart tracking algorithm that maximizes the energy from the solar PV module(s) and charge the battery. It supports over four charging options: sealed, gel, flooded and user-defined. Battery parameters can be set using the attached MT50 remote meter. |
MT50 Remote Meter:Wide LED screen displays the real time operational data and the working status in digital, graphic and textual forms. Basically used for monitoring and setting the controller, it automatically identifies the type, model and relevant parameter data of solar controllers. |
Battery Temperature Sensor and PC Communication Cable:It is used to monitor each controller on the network using Solar Station PC software and update the firmware. Measures 3m and works great for Tracer BN/A series MPPT charge controller. The connectors are well made to secure the connection. |

Excellent performance but beware of Li-ion compatibility
Excellent controller. This is now my third Tracer (sold by SolarEpic) MPPT solar controller. This is installed in my RV with 3 100w Renogy in series charging two 6v golf cart batteries in series. Another charging a 4 6v golf cart battery system wired in 24vdc. A third is charging a 12vdc system charged by 2 Renogy 100w solar panels on a solar tracker I built. This one has been charging the batteries for 3 years now without a hitch. The original batteries are still there and are still working. This controller has no fans and is built very rugged. It has been withstanding the jars and jolts of our travels with no problem. We have the output of this controller in parallel with our original RV charger so when needed we still can plug in the AC to our RV. It is absolutely quiet making no noise and produces little heat with our 300w system. The MT50 panel monitors both the input and output status of our system and is momentarily lit for night operation. As someone else mentioned in a review, the information given by the MT50 is more than I expected.One note, I am not sure I would use this controller with Li-ion batteries. It claims compatibility but Li-ion batteries require a complete off condition for the charger when the batteries reach full state. I have seen no indication in the documentation that this controller does this.
