I've learnt so much since that post of mine. Firstly, not to hijack. Secondly, 1C batteries for the win. I ended up installing an AM2, and almost 2 years later, I added another AM2. Happy with my setup, except that I should have gone with an 8kw. The upgrade now is so pricy, almost does not make sense.

Sunsynk 8kw paired with 2 x Hubble AM2s and 16 x 540w JA Solar panels. 

Beautiful installation. I true pleasure to look at.
If I may ask a question... Did you consider using a busbar for the installation? If you did, why did you decide against it?

Don't waste your money on a Riot mate. They are overpriced fridge magnets at best

Riot doesn't even work for Hubble...😠

Nice one, thanks!

Thanks to @Bloubul7and all the other contributors. This is my HA dashboard. It has all I need to view at a glance. (PS: really impressed with the Sunsynk)
 

Yeah, I was being overdramatic. Mine works, but is better served as a fridge magnet. One thing that was good, was the battery cycles... until they disabled it. I feel cheated out of the R2,500 that I paid for it.

Watch this Space.. 😉

As stated above, change the ID on the inverter - mine reset it's ID to zero after a firmware update:

This did it, thanks. 

@Saliegh The Sunsynk 5kw has a "maximum continuous pass through" of 35A. 
@ 220V that works out to +- 7700W, usually a bit less. 
So when you are connected to Eskom and you pull more than 7700W the inverter will trip out. 
If you are not connected to Eskom and you pull more that 5000W the inverter will trip out.
Running a 3kw geyser of a 5kw is possible but would require some management, especially during load shedding, just needs someone to turn a kettle/toaster on and together with your houses base load you will be over 5kw.
I would suggest using a smart switch and build a Node-Red flow in Home Assistant to ensure that the Geyser does not switch on when there is load shedding i.e. No Grid Frequency - Turn off the Geyser 
You also obviously need to ensure that your batteries are able to supply enough Amps for 5kw - 105A @ 48V
 
 

The inverter will shut down with and F18 over current warning. If the over current is to significant you will damage the inverter

This device adds almost zero value to the whole solar system. If I knew about the Sunsynk Logger being launched I would not have bothered with this 3D printed POS. 
I guess the only good thing about it is the remote firmware upgrades for the AM-2 batteries that I have incase issues occur. But at a cost of over R2k? Wires supplied are short as sh!t too. @HubbleLithium you guys really need to get your devs going with this thing or it's gonna be a magnetic paperweight for many.

As with most of these types of devices, they are triggered by certain events (at least with the schedule functionality in the app), e.g. turn on at 8am, then off at 12pm. If your device does not have power at 8am, and is powered on at 10am, it will not power on.
 
I have one of these astute devices, and they work so well!

If you running HA, you can setup a NR flow that can monitor grid frequency, and use the notify API to send a notification to your mobile fone.

The solution to the original question is that the cable leading to the USB-RS485 converter should be plugged into the BMS485 port on the 5kW SunSynk inverter.

Good day All,
Over the past couple of months I have received numerous requests to share my NodeRed flows used for monitoring the status of the SunSynk inverter.  My initial idea was to package all of the flows into an easy to use package and user interface, however my work loads have not provided me the luxury of time to play around and make it a fool proof system. 
Please note that the use of these flows are at your own discretion with no liability to either myself, this site nor any members of this site.  Do not attempt implement these flows if you are unfamiliar with the working of the ModBus protocol or basic programming.
Brief overview of the flows:
LoadShedStatus - This flow determines the loadshedding status through a webscraper.  I use this information to trigger a secondary set of settings to the inverter in case of load shedding. ModBusRead - This flow is responsible for reading information from the Inverter via the Modbus Flex getter ModBusWrite - This flow is responsible for writing settings back to the inverter via the Modbus flex getter Inverter Monitoring - This flow is responsible for obtaining all of the inverter monitoring values.  The values are then send to Home Asssistant via MQTT as well as logged to an InfluxDB for monitoring via Grafana SSFormRead - This flow reads the current system settings from the inverter and display it via the NodeRed UI SSFormWrite - This flow writes any changes made to the system settings via the NodeRed UI back to inverter SSDSRead - This flow reads the "Default Settings" from storage and displays it via the NodeRed UI.  I use the "Default Settings" to store my optimal system settings when there is no Load Shedding. SSDSWrite - This flow writes the "Default Settings" from the storage to the Inverter.  The flow is also triggered automatically from the LoadShedding status flow SSLSRead - This flow reads the "Load Shedding Settings" from storage and displays it via the NodeRed UI.  I use the "Default Settings" to store my optimal system settings when there is no Load Shedding. SSLSWrite - This flow writes the "Load Shedding Settings" from the storage to the Inverter.  The flow is also triggered automatically from the LoadShedding status flow TimeMode - This flow triggers different settings on different days of the week.  My PV Solar is currently not big enough to carry my whole house, I utilize this flow to feed electricity back into the non-essential loads on the days which my domestic worker is not working.  This helps me to optimize my savings on certain days of the week while maintaining healthy battery levels. NodeRed Palettes required for the flows:
node-red-contrib-actionflows node-red-contrib-influxdb node-red-contrib-modbus node-red-contrib-queue-gate node-red-contrib-schedex node-red-contrib-simple-gate node-red-dashboard The next couple of posts have been reserved to further expand on the hardware requirements and basic set up of the monitoring.
The idea of sharing my flows is to contribute to the community, let us keep this going as a community project by assisting and contributing to project.

Hey Saliegh.
 
My recomendation would be to install HA OS: https://www.home-assistant.io/installation/generic-x86-64

Once done, install the Node Red add-on from the included add-on store.
Then you can start with the flows in this thread.
 
I also recomend the Everything Smart Home channel on Youtube. Loads of useful guides for HA on there: https://www.youtube.com/c/EverythingSmartHome/featured

Hi Powerforum Group,
Herewith a short video of the new RIOT features coming in the next week. Remote Axpert control through the cloud. More features will be deployed soon. Next will be Sunsynk monitoring and control dashboard.
