I think the RS485 module in mine went belly up this weekend.. Where did you order a new one? The CC still works fine,, just no comm to the MT50.. it only says connecting..That adapter cable is critical as I found out myself.
I accidentally plugged the RS485 cable directly into the mini PC I use for monitoring and it fried my Epever controller.
New one works like a champ. I get comm errors on occasion. I was told this happens when the controller sends/recieves data from the MT50 and connected PC at the same time. Setting the sample rate lower helps but still get errors on occasion. No big deal. Just close and reopen solarstation.
None of this olde skool software is user friendly for software dotards like myself but practice makes perfect.
I Replaced the charge controller. I don't think you can get service parts.I think the RS485 module in mine went belly up this weekend.. Where did you order a new one? The CC still works fine,, just no comm to the MT50.. it only says connecting..
I think so? Would have to check the PINOUTS to be sure. I am recalling from memory things I did two years ago as part of a much larger project.The EPEver cable is proprietary?
What is a 'RS485 jack'? I'm not aware of a PC or laptop with such a port.
I got the 'special adapter cable' and no issues.
Just a tad....Ah well, a POE switch might well make a difference eh?? LOL
My controller is barely a year old..I Replaced the charge controller. I don't think you can get service parts.
Disconnect power and reconnect and see if your MT50 connects. Make sure nothing else is plugged in.
If you plug the CC directly into an RS485 jack instead of using the included USB adapter cable, then the CC is probably damaged.
Yeah. Sounds like it fried. See if they'll warranty it. Did you get off Amazon?My controller is barely a year old..
I have disconnected it totally to see if it would reset.. Nothing....
The MT50 was always disconnected before i connected and used the USB / 485cable.
The MT50 was fine for months, and then one morning i go to check on things, and it just says CONNECTING........
I'm hoping the module inside the CC can be replaced..
Just a tad....
I do like the CC though. I have no experience with others but for the price it has good customization and you can watch it ramp down current and go into float along with things like being able to set boost charge time period etc.
It can be confusing because you can set "boost" at 14.8 volts and the time for 2 hours. It only counts the time at 14.8 volts towards the 2 hours so it can stay in boost mode much longer if the voltage threshold is not reached which makes you think changing the settings isn't making any difference. Or maybe I am the only one that didn't know this.
Same with equalization mode.
I've done all that.. i have 2 units, i swapped things back n forth, the problem remains with the CC.Yeah. Sounds like it fried. See if they'll warranty it. Did you get off Amazon?
Try all the USUAL stuff first. The pin fit on the back of the MT50 is sensitive. Make sure you're getting good connection. Try a different cable etc.
In your case the MT50 is getting power but the CC isn't responding to requests for info.

The CC works fine otherwise. the built in display is fine. Just the MT50 doesn't work..
I don't Shop Amazon. The 2nd unit i bought off Ebay.. I can't remember where i got the 1st unit.
I'm not sure of the warranty on it either.. But if i have to buy a module, that's fine.. I just don't wanna buy a whole new unit..
I paid too much for these as it was..
The CC is working fine,, charging the batteries etc.. only no comm with the MT50..When you say it works fine, you have hooked it to panels and watched it charge in it's current state where the MT50 will no longer connect?
When mine failed (when I failed mine) the CC still came on with the green light and without the red warning light flashing (I have the 100 amp model). You could toggle through screens and change settings on the CC but the MT50 wouldn't connect, the PC wouldn't connect and the charge controller would not charge.
It would show PV voltage and battery voltage but not charge.
I have two tracers using the EPEver software, loaded on three different computers, no issues, works fine.
Just contradicting the claims here, should anyone be looking for product feedback and reports.
EDIT: Just looked at OP's images again, and somehow I don't think he has the right program installed. It doesn't look like what I have. Download link here: https://www.epever.com/support/softwares/
The 'solar station monitoring software' version is 1.95 Windows, 11K downloads. It's the first link on the righthand column.
Just now downloaded and installed without issue on my work client, WIN10 machine.
I didn’t like that thing.the MT50
No but look for an adjustment screw on the board.Update >>> I finally got the replacement board for my controller.. I thought the board was just for communication. turns out it is also the Main CPU board. I was told that this would be an easy repair job.. Nooooooooo
when i got the board, it looked like it'd be a plug n play. Nooooooooo
Had to take the whole unit apart. That wasn't too hard to do, but be cautious removing the cover, the display cable to the main board is short.
Looking further into the unit, I discovered that the header pins weren't socketed, dual row 19 pins ( 38 total) This wasn't going to be an easy job.
Luckily, I am very Experienced in electronics and was able to unsolder them without destroying the board. I got the new board installed.
total job took me about 3 hrs.
I got the unit reinstalled, tested it,, Had to reload all my parameters. All is working now, but the voltage reading is 0.9V off compared to my other charge controller and my meter..
I sent a message to the tech and asked if there is a way to calibrate the voltage..I'm sure I'll have to calibrate currents as well.
Anyone here know how to ? I see no info in the "SolarStation" program..or the MT50..
