Configuration for Fronius Symo 20-3

[Macrisu]

Hello!

I could not find any info for Fronius Symo 20-3 Inverter + connected Fronius grid smart meter.

The 20 kW inverter has 2 mppt (from what I know).

Geht auf jeden Fall als „sunspec“. Nicht sicher, ob wir dafür ein fertiges Template haben; mit Plugins ohne Weiteres machbar.

/cc @premultiply vllt sollten wir mal ein „SunSpec Hybrid“ Template basteln?

I think I've found the setup, using float Fronius modbus config

`

• name: grid
  type: modbus
  model: sunspec
  uri: 192.168.1.197:502
  id: 240
  power: 213:W # sunspec model 213 meter

• name: pv
  type: modbus
  model: sunspec
  uri: 192.168.1.197:502
  id: 1
  `

So, the answer is this:

1. Activate Modbus using the service user, with those settings:

2. Run ./evcc detect in order to find the ID and type of the Smartmeter + PV meter (inside inverter).

This is the working config:

meters:
- name: grid
  type: modbus
  model: sunspec
  uri: 192.168.1.197:502
  id: 240
  power: 213:W # sunspec model 213 meter

- name: pv
  type: modbus
  model: sunspec
  uri: 192.168.1.197:502
  id: 1

Since evcc 0.93, there are new sunspec templates
