Just had a look in the files (don’t remember so good, because thankfully my wife did most of the reverse- engineering): the Battery2 values should start at 0xe200 / 57856, grep for Battery2 in the php and work your way up for the values.
Running the docker against the solaredge and “watching” it with wireshark also works well - wireshark has a ModBus TCP decoder builtin. Good luck.
