EPEVER MPPT Charge Controller 20A 12V/24V Auto Solar Panel Charge Controller Intelligent Regulator Tririon2210N wth DS2 + UCS modules (20A,Triron2210N)

I have two Epever charge controllers. 40 amp and 20 amp in use and one 20 amp as a spare just in case. One of my 20 amp controllers came with a bad USB/RS-485 port. Had to contact the sellers which are in China. Took some time, but they are sending a replacement module under warranty. That's really great of them! It took time to work via messages thru Amazon to the folks in China. Different time zone makes it time consuming. All said and done, the problem is on the way to resolution and they provided a way to purchase additional modules which I wanted since they are a key piece to my solar charge controllers. I use the Epever e-box to slow Bluetooth connection from my android phone to program the finer details into the controller. I can tell you that if the module interface fails, it causes many problems trying to program or un-program the controller. But, when all is good, these controllers work 24/7 very well.

I’m really impressed with this. I saw Will Prowse review this on YouTube and it drew my attention to it, I’m upgrading my camper to use a lithium iron phosphate (LiFePo4) battery and needed a new solar controller that has a lithium setting. This certainly does the trick and also has a thermometer to stop charging or discharging the battery at low temperatures. There are a pair of USB charge ports on the face of the controller which makes it convenient for charging phones, pads, etc. The directions indicate that a monitoring cable can be purchased if you wanted to use a computer to really dive into it. I’m pretty impressed for what I got for the money.
