I have two similar Epever charge chargers, one on the sailboat, and one still at home that I am playing with.
I found the initial setup to be very easy, and the controller seems to be reliably doing what it is supposed to do. I highly recommend to get at least the MT-50 display.
My favorite feature is the serial interface, which allows things like the Epever Elog, Ebox-BLE bluetooth, Ebox Wifi, MT-50 display, and laptop to be connected. Quick note on these devices:
MT-50: I like it. It works reliably, has a nice display, and makes it pretty easy to program your controller.
Elog: I like it. It logs your data while allowing other devices to read data from the controller. Data can be downloaded for use in spreadsheets or other programs. This is especially nice if you controller is in a remote location.
Ebox-BLE: Allows your phone to connect with the free Epever app. Decent.
Ebox-Wifi: For use with same app as bluetooth. You need to connect your device (phone/tablet) to it directly so in most cases you can't also be connected to your home network with your device. Despite this down side, it is useful if you don't have bluetooth, want to use your bluetooth for other things, or don't have a wifi network you need to stay connected to (might be the case in an rv/boat - elog will still capture your data while you're not connectd). If you want to delve a bit, this can be used as a serial-to-tcp interface, but the app will not work in this mode, and there are probably better ways of doing this.
But the best part about the serial interface is that Epever kept it simple and standard. Because of this, things work reliably and it is simple for anyone to set up the controller with the MT-50 or app. Equally important, for those who are interested in real-time monitoring and statistics, it is easy to read to data from the controller to do with want you want. Pretty much everyone has their own needs with regard to what they are interested in monitoring, and how they want it displayed, so being able to read data from the controller is a mandatory feature. In my case, I don't have anywhere to place my solar panels to get full sun, but my batteries are critical because they run my bilge pump. Even with partial sun, the controller works very well to keep my batteries charged, and the serial interface allows me to monitor what is going on in a way that suits my needs.

After a month no complaints. Just be aware the terminal screws for cables are chincey and take great care anytime your using them and the set up instructions for a minimally intuitive pensioner like me from Chinese to English translation are minimally helpful and could be improved.

Works good for me This is the second one that I bought from Amazon first one has been working good eight months or so I decided to add more panels and added another controller there is no way to set it up for lithium batteries on the unit itself but with a Bluetooth adapter or a Wi-Fi adapter you can download the android app and set up for lithium batteries I am in Quartzsite Arizona for the winter and I'm fully charged with the new panels and charge controller by 1030 or 11 o'clock so loving my new controller getting me through the winter.

Exactly as described.

This charge controller came well packaged. I am using it for Lithium batteries. Setup was easy as parameters settings for Lithium batteries is in the configuration settings. Use the rs485 cable to pc and Epever software to setup system.
