I have tried the replacement unit that Jon sent (it is a V4 and the original was a V3)and unfortunately I still cannot get any data to be displayed from my Epever AN5415.

Here is where things stand.

The V3 and V4 are behaving exactly the same.
The V3 was working perfectly when I first installed it including via the cloud. It stopped displaying data after a few days for no apparent reason.
I can access the dashboard both directly (192.168.4.1) and via local wifi
The five meters show “NaN” and “unidentified KwH”
The log keeps showing “Epever Modbus Error Read” and “Main Current sample data is invalid”
Firmware is “4.0-4c05ee-2020-09-06-01-00” previous updates have been no help.
An empty graph is being displayed (no data lines) so I assume the SD card is being recognised.
The blue LED is flashing every two seconds

It would appear that the problem is with the controller which is not sending any data but my Epever MT50 meter works perfectly using any of the three cables I have tried. Doesn’t this mean that the RS485 port and cable are OK?

Am I missing something?
Thanks
Tony
Hey can you post your log file?

Some other things to try:

- Powering off the epever my disconnecting both battery and solar and reconnecting after a few mins.
- ensure your cable is plugged in all the way with the little tabs engaging
- take a video of the dashboard without the plastic cover so we can see the behavior of the lights for about 30 seconds.

I am attaching the log files from the time I installed the new unit (V4)
i don't seem to be able to attach an MP4 file so I will email the LED video to you
You will notice that the logged data starts at 00 hrs and stops at 06.00 every day for some reason.

I had already tried switching the controller off (both battery and PV's) but forgot to mention it.
Pushing the cables in tight makes no difference.

Thanks I got the video and logs. Can you use the MT-50 to confirm the modbus address setting on the epever?

if it is possible to use the MT-50 for this purpose then I'm afraid I don't know how to do it.
This link shows the full MT-50 manual
