G0emf, I've just noticed that you had the same problems logging into the Pi. I can access Node Red and Grafana and I can now get a login prompt if I SSH onto it. I just dont know what the correct username and password is, it doesn't appear to be pi & raspberryNo the image is for a Sofar ME3000SP & it is working. But I need the credentials for the Pi & Grafana logins.
I can see the Wiki for the forum is being updated as I type, but the credential are incorrect.

Hello @shavermcspud
Hoping you can shed some light on my challenges getting this running on my side.
I flashed the image file, but on boot Grafana, InfluxDB and MQTT does not startup. There's likely more not working that I've yet to discover.
I purged Grafana, InfluxDB and MQTT and reinstalled. All running now. I get to the dashboard now but there isn't any data loading.
pi@raspberrypi:~ $ ls /dev/*USB*
/dev/ttyUSB0

My RS485 to USB adapter shows as /dev/ttyUSB0. Change the serial-port in Global config on NodeRed to reflect this. I'm certain I'm cabled up properly - A to A and B to B.
I'm likely missing something obvious and was hoping you can point me in the right direction.
Solis RHI-5K-48ES. Downloaded and flashed the Solis image in the repositoryWhat inverter do you have?
Are you 100% sure you have the connections right from the USB to RS485 connector?Solis RHI-5K-48ES. Downloaded and flashed the Solis image in the repository
Yes. Absolutely positive the connections are right.Are you 100% sure you have the connections right from the USB to RS485 connector?
Ah yes, its not for the Pi zero, the Pi zero doesn't support the versions of OS or grafana/nodered.Yes. Absolutely positive the connections are right.
I suspect grafana, influx and mosquitto were all broken after flashing because your image is likely meant for something that's not a Pi Zero perhaps?
I've got grafana, influx and mosquitto all running just fine now though. Double, triple checked that the connection from RS485 to inverter is right. Swapped them about as well. Still shows "no Data"
Thanks. Time to go on a hunt for a proper PiAh yes, its not for the Pi zero, the Pi zero doesn't support the versions of OS or grafana/nodered.
Pi3 or later, As a side note, did you download the version for the Solis or the Sofar unit? if you look at nodered do you see any data?Thanks. Time to go on a hunt for a proper Pi
From my prior research there is no official suported version of Grafana that functions on the Zero due to being an older Arm architecture, i gave up in the end even compiling from source i couldn't get it to work.I downloaded the Solis version. Nodered does indeed show data and actually all appears to look just fine in that space. By getting Grafana,Influx,MQTT up I just thought it would magically work despite having a sense it wouldn't because of the Pi zero and hiw different it is to the other Pi's
Happened upon this,From my prior research there is no official suported version of Grafana that functions on the Zero due to being an older Arm architecture, i gave up in the end even compiling from source i couldn't get it to work.
But what is putting the data there? I'm guessing there is some daemon that is using the various serial protocols to poll the inverters, get the data and then save it to the RAM disk. Does Grafana orchestrate that? Or is it something else?
