EPEVER MT50 Remote Meter for MPPT Solar Charge Controller 10/20/30/40A,50/60/80/100A LCD Display Monitoring Setting Datas of Solar Panel Battery Regulator System (MT50)

I purchased this cable to interface between the EPEVER 10A MPPT Solar Charge Controller and the PC . The Solar Guardian PC Software is free on EPEVER.com and it make programming and monitoring very easy. It works very well with no lag in data transfer.

Plugged right into my EPEVER PWM 60A Solar Charge Controller and works perfectly! This is used for keeping track of battery temps and allows the controller to adjust the charge rate based on battery temps. Worth the money!

Using on a EPEVER Tracer AN 30A MPPT, indoor use. Bluetooth comm failed after ~6 weeks. My app is installed on Samsung phone that had at least one update during that 6 week period. Fiddling did not work. Removed the BLE device for a few hours, then decided to remove the Solar Guardian app and re-install before attempting reconnect. Using Local Connection, set controller type and Comm ID "1" and BLE device was found again.There is a small hole at the end of the BLE device. I tried a paperclip there but could not "feel" any reset button. I doubt if this attempt had any effect.

Simple plug and play installation, but it doesn't seem to work properly and reads a constant -14 degrees F when it's actually about 40 degrees F. I tried to reset the controller unit, unplugged panels and battery power several times, unplugged and re installed temperature probe and it goes back to -14. At least it was inexpensive, but not worth the hassle to send back...

This unit will drop connection and requires a mechanical reset, meaning you have to unplug unit and replug it to start wi-fi again. So, if you aren't home and it goes offline then you're out of luck. I have ruled out poor wifi signal as I have other devices further away that do not drop. I have utilized an extension in the hookup and have reduced drops to about 1 or 2 a week. Not bad now.The app provides useful information from my solar array.

I had MPPT inverter for over a year and multiple attempts use arrest for 85 port connection and my computer to program. It was very painful, never really succeeded. Always trouble through the windows to find the correct driver. Then the software never really dumped the programming into it and I give up. Then almost a year later after that event I decided you know. Let's give it a try. This little remote console I say red that it should be able to program my inverter to charge my lithium battery properly. Guess what? It took me 10 minutes to set everything up. The word of advice in my setup. I do have a full access to my MPPT inverter and it's reads out and it look like I don't need to have a remote console so I always carry the remote cancel with me in my camper just like a programming pad and I'm using only when I need to change something. Day-to-day charge level voltage currents I'm using the readout of the inverter. And this pretty much became a maintenance counsel.

The Solar Guardian app took a bit to figure out when I set it up, but it's nice being able to access the info from anywhere there's cell signal.

This made my MPPT charge controller WiFi ready now. Use it on a tablet to monitor system. Great item!
