Thank you... still getting my head around this... and sorry, leading zeros were truncated..... The inverter sends this request: Rec Buffer: 01 03 00 00 00 41 85 FA host address: 01 function code: 03 start address: 00 00 number of registers: 00 41 checksum: 85 FA Would you be kind enough to...

Thank you @peufeu for your help.... My Solis S5 is happy (no failsafe) with the data I am sending :-) I now just need to start playing with values to confirm the active power position in the data - then start using the actual grid power rather than fake data.... But first need to figure out...

Well, I got the thing sending some response on Modbus.... but of course not the response the inverter is requiring. I am not really clear what the minimum response expected by the inverter is? 30945 130004185FA process register read 1 3 0 65 gridpower: 56.00 response 2 4 4 42 60 0 0 DC E2...

Ok.. some progress... Firstly, I was populating "export power energy (kWh)" - which was the wrong field.... The word 'power' had me thinking this was it..... I am now populating Export_P. The other relevant field I can look at (and populate if required) is Export_I. There is no display of...

Thank you... The goal is not to save money - but to get the grid data to my inverter is going to require a wireless link (purely from a logistics / cabling point of view) ... I already have the grid import / export data in HA (1Hz is no issue) and am sending that out over MQTT (again at 1Hz)...

I have a Solis S5 S5-GR1P(3-6)K 5kW inverter. It is a ‘meter’ type - not CT type. I want to use export limiting. But rather than buy a separate power meter to feed ?modbus to the meter port on the inverter, I would like to use grid import/export data I already have within Home Assistant. Can I...

My Solis inverter has two meter choices... acr10rd16te or ddsd1352-c. I have set it to acr10rd16te. On the RS485 meter-port I understand the Solis acts as master and the smart meter (my esp8266) is the slave. I have confirmed the inverter is sending out what I guess is a Modbus request (pic...

Sending this (0x01, 0xF4) results in 5.0kWh on the soils display. I presume this positive number represents grid export? response 01 03 82 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00...
