fronius

This module collects metrics from the configured solar power installation from Fronius Symo.

Requirements * Configuration file fronius.conf in the node.d netdata config dir (default: /etc/netdata/node.d/fronius.conf) * Fronius Symo with network access (http)

It produces per server:

  1. Power * Current power input from the grid (positive values), output to the grid (negative values), in W * Current power input from the solar panels, in W * Current power stored in the accumulator (if present), in W (in theory, untested)

  2. Consumption * Local consumption in W

  3. Autonomy * Relative autonomy in %. 100 % autonomy means that the solar panels are delivering more power than it is needed by local consumption. * Relative self consumption in %. The lower the better

  4. Energy * The energy produced during the current day, in kWh * The energy produced during the current year, in kWh

  5. Inverter * The current power output from the connected inverters, in W, one dimension per inverter. At least one is always present.

configuration

Sample:

{
    "enable_autodetect": false,
    "update_every": 5,
    "servers": [
        {
            "name": "Symo",
            "hostname": "symo.ip.or.dns",
            "update_every": 5,
            "api_path": "/solar_api/v1/GetPowerFlowRealtimeData.fcgi"
        }
    ]
}

If no configuration is given, the module will be disabled. Each update_every is optional, the default is 5.


Fronius Symo 8.2

The plugin has been tested with a single inverter, namely Fronius Symo 8.2-3-M:

  • Datalogger version: 240.162630
  • Software version: 3.7.4-6
  • Hardware version: 2.4D

Other products and versions may work, but without any guarantees.

Example netdata configuration for node.d/fronius.conf. Copy this section to fronius.conf and change name/ip. The module supports any number of servers. Sometimes there is a lag when collecting every 3 seconds, so 5 should be okay too. You can modify this per server.

{
    "enable_autodetect": false,
    "update_every": 5,
    "servers": [
        {
            "name": "solar",
            "hostname": "symo.ip.or.dns",
            "update_every": 5,
            "api_path": "/solar_api/v1/GetPowerFlowRealtimeData.fcgi"
        }
    ]
}

The output of /solar_api/v1/GetPowerFlowRealtimeData.fcgi looks like this:

    "Head" : {
        "RequestArguments" : {},
        "Status" : {
