# 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:
```json
{
"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](https://www.fronius.com/en/photovoltaics/products/all-products/inverters/fronius-symo/fronius-symo-8-2-3-m)
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.
```json
{
"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:
```json
{
"Head" : {
"RequestArguments" : {},
"Status" : {
"Code" : 0,
"Reason" : "",
"UserMessage" : ""
},
"Timestamp" : "2017-07-05T12:35:12+02:00"
},
"Body" : {

"Mode" : "meter",
"P_Grid" : -6834.549847,
"P_Load" : -1271.450153,
"P_Akku" : null,
"P_PV" : 8106,

"E_Total" : 14788870,

},
"Inverters" : {

"DT" : 123,
"P" : 8106,
"E_Day" : 35020,

"E_Total" : 14788870
}
}
}
}
}
```
