Has anyone had a successful experience connecting Pylontech UP5000's to Sunny Island Series 6-11 battery inverters and if so did the install also successfully include the connection of the COMMS cable?
According to the SMA SI-LiIon-TI-en-45 doc connecting Pylontechs are approved but I am not sure on the COMMS cable wiring required.
The other alternative I have been considering is the BYD BATTERRY BOX LV FLEX LITE units but the above SMA battery doc says not to use for off grid, maybe somebody can also pass on there experience with these models please.
