The one thing that causes the most problems with SA and the Pi is the Power Supply.
Everytime I have had weird issues it turned out to be the Power supply. I do not know why this thing burns through power supplies so fast but I am on my third one in a year. As soon as I changed it the lockups stopped, the WiFi disconnect issues stopped and also times when it would stop receiving data from the 485 port. In every case a reboot fixed the issue for a few days and then it would come back.
I eventually changed the Power Supply and the problem is gone for good or until it needs a new one again.

I ordered the battery terminal power supply from Solar Assistant when I bought the whole shebang from them. So far so good. I might mention that I’m fooling around with Home Assistant and most run that on Pi’s too. There are lots of failures and a growing number are buying slim clients off of eBay and installing on them instead of Pi’s. Slim clients are small computers and are designed for continuous use. They buy them with SSD’s installed. Pretty neat and it is easy to find them with 8gb ram and 32-64gb of SSD for around $50 usd. I have one coming to experiment with but if it works out I’ll buy another one and install SA on it.

No other than they can run HA and HA runs on a Pi as does SA. I have sent an email to SA.

Good luck installing it on anything except Pi and Orange Pi 3 LTS. I've tried with armbian builds for other SBCs but didn't worked out. I have a 40 core Xeon Gold server with 128G RAM sitting next to it, and can't leverage that because SA won't support VM installation.
Mine died at me while nobody is close to investigate. no ssh, no watchdog, basically you need to walk across half a world to unplug and replug it.
I'm currently browsing the disk image and could not find anything remotely connected to SA, only the Grafana install.

It may not be possible. I know some are having issues with SA and HA on their Pi’s. Seems data loss and long term Pi reliability are the primary issues. I am trying to find a more robust platform to install it on.

I have such freezes every day once or twice
Data just stops. Power supply is not an issue. I have meanwell din rail power supply which i trued 4.95V 5.2V 5.6v, same on all voltages
When i reboot SA, or disconnect connect by button rs-usb converters all goes fine

Solar Joules are catch and release
This. I’ve been using Pis since the first one came out, and nearly all my problems have been power supply or SD card. I standardized on SanDisk Max Endurance cards and most of my problems disappeared.

It won't run on anything other than the supported hardware listed on their website:
Load SolarAssistant on Raspberry Pi
Flash SolarAssistant on to a Raspberry Pi in a few easy steps.

Have the exact same problem.
Have meanwell din psu, tried 4.99V, 5.2V, 5.4V.
Tried different RS USB converters.
Tried different PSU
Tried joining beta channel for any firmware change about this.
when i was running 2 inverters all was fine, when i added 3rd inverter to SA. i get the data just frozen every hour or so.
If i click disconnect and connect to RS-USB converters its all okay.
Im running Orange PI 3LTS with a heatsink and a cooler, it is not thermal throttle or something like that.
Have you found any root of this issue?

How do i clone an SD card not to loose the data?
Can you share the process you make to do that?
It is really the last thing i didn't try

You can use a tool such as Balena Etcher
balenaEtcher - Flash OS images to SD cards & USB drives
A cross-platform tool to flash OS images onto SD cards and USB drives safely and easily. Free and open source for makers around the world.
etcher.balena.io
If you have a bad SD card though it may not help.
Solar Assistant has a data backup option, I suggest using it to at least generate one backup.

It got better, but freezes every day 1-2 times, and i need to disconnect and connect usb in settings to normalize
I also tried usb powered hubs with no luck
Still getting freezes

Perhaps the data has been corrupted.

Yeah my power supply was an issue too, I use a 110 version now from Amazon plugged into the output from my batteries and far more stable results then the battery option. The WiFi has also been an issue and I had to install an extender to get better WiFi.
