Fronius Inverter FAN RPM


#1

Hi,

I have a Fronius Symo 5.0-3-M inverter [ 3.12.2-2 ]. I would like to extract and upload the ROTATION_SPEED_FAN data from it.

Page 10 of Fronius Solar API V1 in section 3.1.3 shows that this information can be extracted from 3 phase inverter, which mine is. Yet when I run the query it only returns the Voltage and Current data for L1, L2 and L3.

Is there anyone out there with a 3 phase Fronius inverter who can see this data using the provide URL? Don’t forget to substitute the IP address for fronius if required.

http://fronius///solar_api/v1/GetInverterRealtimeData.cgi?Scope=Device&DeviceId=1&DataCollection=3PInverterData

My plan was to generate an alert if the speed of any of the fans falls below some minimum - to be determined.

Thanks,

This is what I get:

{
"Head" : {
	"RequestArguments" : {
		"DataCollection" : "3PInverterData",
		"DeviceClass" : "Inverter",
		"DeviceId" : "1",
		"Scope" : "Device"
	},
	"Status" : {
		"Code" : 0,
		"Reason" : "",
		"UserMessage" : ""
	},
	"Timestamp" : "2019-03-07T00:31:55+11:00"
},
"Body" : {
	"Data" : {}
}

}

Same with mine. But its a single-phase inverter, not a three-phase inverter.

The complete output from my inverter is shown below. I sent an email to Fronius asking for some clarity on this particular API call.
