Dear All,

Do anybody know if it's possible and from where to find ModBus Interfaces Definitions for SUN2000-36KTL ? Thre is a lot of similar information floating arround, but its for different models, and most of the registers are not available on my model. My attempt to read any of them, most usually ends with following response: "Slave reported illegal data address" which if I undestand it correctly means that inverter doens't have or not support such address. Until now the only reg that I've been read back correctly is 40000 (Time).


Thanks,

Kiril

Hello, dear.
The inverter MODBUS definition file on the website has been hidden. The way to get it is to send the device SN number + get the MODBUS file to this email eu_inverter_support@huawei.com
