SolarEdge SetApp protocol buffers parser library

Project description


solaredge_setapp is a python library that parses inverter and power optimizer data from a compatible SolarEdge PV inverter. Only those models which support SetApp commissioning are supported.

This project is built on the efforts of others: for Home Assistant users, see drobtravels' solaredge_local, and jbuehl's solaredge for all non-SetApp power inverters.

Developed and tested on a European SE3500H-RW000BNN4 SolarEdge Inverter -- CPU version 4.6.24 (previous 4.5.41) and WSA 1.2.9 (previous 1.1.12).


To install, either clone this project and install using distutils:

python3 install

or install the package from PyPi:

pip3 install solaredge_setapp

Working on protobuf messages

Clone the project if you want to modify the protocol buffer messages.

In order to use to (re)compile the protocol buffer .proto message definitions you will need protoc, which is provided, for example, by Ubuntu's package protobuf-compiler. (Re-)compiling the protobuf messages is only necessary if you have made changes to them.


See how to fetch, parse, and display the SetApp protobuf files exposed by the SetApp API.

python3 your-inverter-ip

Basic usage of the status API endpoint:

import solaredge_setapp
import requests

inverter_ip = ""
status_bytes = requests.get("http://{0}/web/v1/status".format(inverter_ip)).content
status = solaredge_setapp.status.Status()
status_data = status.parse_protobuf(status_bytes) 

print("Inverter {serial} is {status} at {power_ac:.2f}W".format(

See the status.proto file for all possible fields, and solaredge_setapp/ for all fields that are parsed for this endpoint.

The following API endpoints are available:

  • app_configs - language and functionality
  • communication - ethernet, wifi and RS485 settings, not yet implemented
  • device_manager - unknown, not yet implemented
  • information - CPU and DSP versions, error logging
  • maintenance - power optimizer telemetry
  • power_control - grid power settings, not yet implemented
  • grid_protection - grid protection settings, not yet implemented
  • region - language and country settings
  • status - inverter and energy statistics


The SetApp API does not (yet) provide real-time power optimizer data. Initial results suggest the data is 5-15 minutes old. Inverter production and voltage information is near real-time, however. Basically, the entire information set visible on the inverter's SetApp web interface is available through this library, in addition to per optimizer voltages and temperatures.

Rate limiting will kick in if you have the SetApp web interface open while also polling using this library.

The SetApp API is new, and therefore likely to change. Variable naming and distribution is likely to change.


Contributions are more than welcome, especially to the protocol buffer message definitions.
