I have found this unit to very well made and it is much more efficient than the 450 dollar pwm controller it replaced. The included MT-50 monitor included is also very nice to have
Great low cost mppt type charge controller which is easy to setup and really does its job well
Really like this charge controller. The MPPT really makes sure the batteries are fully charged. I have 4 - 300 watt panels with this controller in a series/parallel setup with 79 volts going into the controller. It handles it no problem. I also like that it came with the remote monitor. I can place that in a more convenient location to monitor solar/Charger/battery conditions.
I tested and opened it up and YES, it is a real serious MPPT. I did a video on it but its too big of a file to put here on Amazon.
Hopefully you can find it by searching. Do a internet video search for: EPEVER EPSOLAR 4210A MPPT Solar Charge Controller OPENED UP! A very in depth video but too big in Mega bytes to put on here.
Possibly the link can get allowed [...] and you can see why you need to get one.
Don't forget the meter too.
