EPSolar AN series to RS485 to Ethernet

[PVorBust]

Why not? What behavior are you seeing?

No idea 'why'. It was working fine until I moved it, then nothing. On its own display, it looks like its trying, but it's set to 24V (not auto), so just thinks the battery is flat.


As for the behaviour, it 'looks' normal, but no comms out the RS485 port.
I've tried the MT50, the USB cable and a RS485-Ethernet bridge - nothing.

Trouble is I can now not communicate with the SCC to change the voltage setting.

Are you contacting Epever directly or your reseller?

Are you contacting Epever directly or your reseller?

I was trying to contact Epever direct both by email and using contact page on their website

6th attempt to contact epever finally got a reply.
Their suggestion to deal with the 'voltage setting' is the use the front panel and select the User Settings option and set it up that way.

There were no suggestions how to do any kind of reset, and the only the only observation about the lack of comms via RS485 was "perhaps the port is damaged", and asked for photographs.

happy holidays & merry christmas! ?
good luck with the solar stuff!

Further to this: The 'AN' model of SCC's are unable to use older MT-50's from "non-AN" models (due to a protocol issue). Seems silly that they didn't change the model #'s on the 'new' MT-50's though...

Yeah, they did.
The older (RN) SCC speak RS232 and their display is the MT-5
The newer SCC speak RS485 and their display is the MT-50

(RS232 is ok, but only works between two devices. RS485 is more suitable as it allows many devises on a single cable and is suitable for much longer cables)

One thing - don't get caught trying to use the renogy display - they look very similar with the same model numbers, but use a different pinout on the cable.

I disagree... watch video :

There are 2 identical MT-50 - but apparently different hardware revisions.

Why don't just call him MT-51 or MT-50 b...

 

[PVorBust]

Ok - that's just dumb.

Now that I've networked all my SCC's, I've put the display aside and it's unlikely to see the light of day again. If you hadn't pointed it out, I probably would have never noticed.
