SolarEdge inverter

[baggins]

Hi,

I have a SolarEdge inverter which supports Modbus.

The Modbus data can be found here: https://www.solaredge.com/sites/default/...l-note.pdf



Before starting to assemble a profile for this, I wanted to check if I could connect to the device and do a simple operation.

I use a script that admin provided in another thread:

Code:

require('luamodbus')

mb = luamodbus.tcp()
mb:open('192.168.0.45', 1502)
res, err = mb:connect()

if res then
  log("connected!")
   mb:setslave()
  r1,r2 = mb:readregisters(40082)
  log(r1,r2)
else
  log('connect failed', err)
end

mb:close()

This is the result I get:

Code:

testing 11.02.2020 14:31:01
* arg: 1
  * nil
* arg: 2
  * string: Operation timed out
testing 11.02.2020 14:31:01
* string: connected!

I took some random address from the manual but no matter what addres I use, I get the same result.

I tried with both 40082 and 82 and also other combinations.

I also tried the script without the mb.setslave() statement; same resul

I can telnet to the device and it opens a connection but I have no idea what I could enter next to get some sort of response.

Am I overlooking something here?
