Hi, i have a SMA sunny Tripower Hybride inverter.
This inverter is compatibel whit HV battery only.
Approved battery list:
BYD HVM 11.0-22.1 ( Max 25A)
BYD HVS 5.1-12.8 ( Max 30A limited by SMA)
LG Resu Flex 8.6-17.2 ( Max 22A)
And other less known brands.
I did by an WatchMon Core + 5 Celmate K9 + Shuntmon 500A.
Now i have problems setting up the Can bus communication to the SMA inverter.
The SMA inverter checks the first 5 minutes after power up for the connected BMS, the battery type ( and BMS) is not having settings to be set, these are read from Canbus.
Now i did try the following protocols:
Project Lychee ( LG RESU simulation)
Reserved 33 for ( Pylon HV simulation)
Reserved 40 for ( BYD HVS simulation)
Now non of them seem to be abel to communicate whit my inverter.
Some protocols give a Rx counter increasing so CANbus wiring is correct.
And setting Remote settings " to default
And after rebooting WatchmonCore and my SMA inverter there is no correct communication.
I did the FW update of the Watchman core and i have set the Celmate K9 in simulation mode as i have not yet bought the battery cells. ( First check that the BMS is capable of working whit my SMA inverter)
I would like to get my BMS system running the “BYD HVS 5.1-12.8 ( Max 30A limited by SMA)” .
Can someone assist me whit my required settings ?
I am strongly doubting on the Canbus " Base Address", Remote Address, Group Address.
Hi all,
is there already any news available? I am also using a SMA Tripower Smart Energy and would like to run it with the batrium cellmate(s) and mom.
Hi,
Its not yet working for me.
I did get the alpha release for Build 56, which contains the Tripower profile.
But even whit this one i don’t get it to communicate.
I am using the SMA STP 5.0 SE.
I am trying to get the Batrium BMS to communicate whit the SMA before i buy the batteries.
The BMS is having a “simulation” mode where it simulates the batteries.
Thanks for the update. Are you still in contact with the batrium developers?
I ordered already a first set of 16 cells to get familiar with the cellmate and mon. My fallback would be using a SMA Sunny Island which should be working with batrium.
Please keep me posted!
We have put together a beta protocol for the Tripower based on bits and pieces we have gathered (SMA themselves do not publish it). It appears that we are not there yet judging from user feedback.
We have contacted SMA, but have not heard back yet. I will keep this thread updated with our progress on that front.
So you didnt try with an actual battery, only in simulation mode?
maybe the SMA needs to see any voltage on its battery terminals before accepting any communications.
Correct,
I first need confirmation that the inverter is able to communicate whit the BMS.
As for the need for battery voltage on the terminals i need to buy$$$ the battery cells.
I will only buy these when i have confirmation that it will work.
Do you have the full system available for test?
Hi James, I am a developer for a BESS that will be compatible with the SMA Tripower SE. We also had issues with the CAN communication which is supposed to be exactly the same as for the Sunny Boy Storage. We got a new FW Version 3.06.18.R that resolves the issue when a battery is connected that uses the manufacturer ID 255. Maybe you are facing the same issues we had and will be fixed as soon as SMA releases the new FW version.
Thank you for this information! We have a profile already for Sunny Boy Storage HV, so perhaps this firmware will also fix things for us too?
We have reached out through the official channels to SMA to get official specs, but despite my best efforts they have not gotten back to us.
We are also finding it hard to get a hold of a real system to test with, as these newer SMA inverters require a specific handshake on startup that involves connecting the battery at a specific time in relation to the CAN comms. This can be done with our Expansion board, but we will need good responsiveness with a test system to experiment with this.
