Hello everyone,
I have a Sungrow SH6.0RS Inverter that is compatible with these batteries.
Sungrow SBR064/096/128/160/192
BYD Battery-Box Premium HVS 5.1/7.7/10.2
BYD Battery-Box Premium HVM 8.3/11.0/13.8/16.6/19.3
I would like to know the possible communications configurations of Wathsmon with Sungrow SH6.0RS.
The configuration I have is:
32S LifePo4 280Amp
WatchMon CORE
Expansion Board
2 CellMate K9
ShuntMon 500 A
Hi DSH,
We can emulate the BYD HVS protocol, so you seem to have come up with a good solution there with those parts 
It is worth noting that you have picked a HV inverter that will only be able to achieve its rated output at the upper end of its voltage range (80V-400V). You should consider an LV inverter or a higher pack voltage if you want anywhere near its rated output.
Thanks James,
I’m glad to know that I’m not wrong,
In two weeks I will start testing the batteries and the BMS.
As you say, I am aware that with 32 units it is not enough to take advantage of, since it is limited to 30 amps. But the idea is to put 96 lifepo units.
I think this inverter fits my future inverter expansion needs.
Two more questions.
1st how to configure the battery as BYD?
2nd, could I, with another Batrium and ShuntMon 500 A, control another inverter with the same batteries without the CellMate K9?

Hi DSH,
Simply select the menu item when running the Wizard Setup:
If you are using the same type of inverter (i.e. both compatible with BYD HVS) then one WatchMon is fine.
If you decide you need two WatchMons, they will need a K9 to control the inverter properly. For example, when the cells reach bypass voltage, the WatchMon will tell the inverter to limit charging so balancing can work properly.
Let me know if you have any other questions
Thanks James.
The final configuration I need would be
96 Bat lifepo4 two Sungrow SH6.0RS inverters compatible with BYD HVS.
The idea is to parallelize the two inverters with the same batteries,
Could I, with another Batrium and ShuntMon 500 A, control another inverter with the same batteries without the CellMate K9?
I don’t know if you can put the same WatchMon CORE on two inverters with the same batteries.
Thanks for the answers, they are very helpful to me.
Hi DSH,
You can :). Two WatchMons are not required for two inverters of the same type. The messages will simply be received by both inverters and both will react accordingly

Very good news, for my economy…
I hope to test the set soon, I will confirm if everything works so that it can be added as an inverter, it works for batrium

Hey, did you get it to work with the Sungrow inverter? Or if anyone els knows if it works?
Hi,
I’m running the Sungrow SR10HT with the latest Watchmon with the solution written above (BYDESS)
Works perfectly!
Only the capacity reading in the ISolarapp is Not correct. My 46kWh Shows up as 5.1kWh which is Not a Problem as the Batrium App gives all necessary information.
Cheers

Hi bymich,
Regarding your capacity reading, what is the config of your pack? And how have you set the Cell IDs under Hardware > CellMon? (screenshot ideal)
Keen to look into this for you!
Hi,
As of June 2024, Australia has officially dropped all support for non-Sungrow batteries
I just bought Australian SH10RS and I don’t know what to do with it now.. Is there a solution for Sungrow’s native SBR protocol? I found a project that has more information about this issue.
Hi James,
here comes the Screenshot. Does anybody know if Sungrow will remove compatibility worldwide through a SW update? This would be a reason for me to turn off the autoupdates…
Funfact about the battery capacity: there are two different values at the Sungrow parameters. The on which is automatically transferred by CAN Bus, in my case 5.1kWh and the other one which can be set manually, which is set in my case with 46kWh.
Cheers
Ralf
Hi Ralf,
Thanks for sending that through, Looks like you have everything set up sensibly there, what do you have set as your Ah in the Shunt tab?
Glad to hear you can override it in the inverter!
Yes, turn off auto-updates. I’m disappointed to hear Sungrow has taken this approach… We will work with any inverter manufacturer that provides us a protocol document, and believe a more open system is better.
Hi ivn,
Chances are it is running old firmware (inverters often sit around for years before being purchased, or at least my gear was), and Ralf suggests you can turn off auto updates.
We don’t have a native protocol yet, but can adopt the native one from that project. I have passed this on to our software engineer.
