I would like to set the “power limit” setting of my Solis 4G mini inverter via Homey. (avoid negative in feed tariff) But when it comes to Modbus I don’t know what I’m doing so I need some help.
I made a Modbus device.
IP set to the address of the dongle.
Port 502
ID 1
connection type single connect.
Homey says everything is fine.
But how to make the flow to read the current setting? And how to put a new setting in?
I understand that I have to use registers. I found a document on the site below. Then I think it is register 3050 (page 12)
3050 Power limit actual U16 1% 10000<–>100% 3X
But the document also writes
5.3 Register address of inverter operation information. The function code is 0x04, the register address needs to offset one bit. Example: register address: 3000, the send address is 2999.
If anyone can make an example of the read and write flow I would be grateful.
