1 Introduction
The Fronius Solar API is a means for third parties to obtain data from various Fronius devices (inverters, Sensor-
Cards, StringControls) in a defined format through a central facility which acts as a proxy (e.g. Fronius Datalogger
Web or Fronius Solar.web).
Currently, the only way to interact with this API is by making a HTTP request to a specific CGI. The URLs for
the particular requests and the devices supporting them are listed at the beginning of each request description.
The API is versioned, meaning that multiple versions of this API may be available on the same device. The URLs
in this document always point to the version of the API which this document describes. The highest supported
version on the device can be queried. See 2.4.1 for details.
In order to check your product for compatibility with this version of the API specification, please see the separate
document provided for this purpose.
The API divides roughly into realtime and archive requests: Realtime requests will obtain the data directly from the
devices and can therefore only be used when the devices are not in standby or unavailable in any other manner.
Archive requests will use the data stored in a central logging facility to obtain the results and are of course not
subjected to the former limitation.
2 General Considerations
2.1 Output Formats
Currently, the only output format supported is JSON, a lightweight data interchange format. It is easy to read
and write for both humans and machines and it offers some advantages over XML, like basic typing and a leaner
structure.
+ It is strongly recommended to use appropriate frameworks or tools to parse json objects properly
2.2 Fronius GEN24

2.2.1 Client Generation using OAS
1
We provide an OpenAPI interface specification file for GEN24 inverters to support client generation in multiple
languages.
Download the file here: https://www.fronius.com/QR-link/0025.
To display the spec you can use https://editor.swagger.io, for proper client generation please use https:
//openapi-generator.tech.
2.2.2 Inverter to inverter communication

Collecting data from multiple inverters in the same network is not supported by so called system requests on
GEN24 devices. To gather the information please invoke ident requests on all GEN24 inverters interested by you.
2.3 Data Types

2.3.1 Numeric Types
JSON only knows one kind of numeric type, which can represent both floating point and integer values. It is how-
ever possible to specify a type in JSON description, but it is always in the hands of the interpreting system into
which datatype a numeric node is converted.
Which range a certain numeric node actually can have is often determined by the device providing the value,
and may also vary depending on the type of device (e.g. ”UAC” can be an integer value on older inverters, but a
floating point value on newer ones).
This means we cannot reliably specify value ranges for all requests. So it is the responsibility of the API user
1 https://swagger.io/specification
5
to determine whether a value fits into a certain datatype in his language of choice.
What we can do is to specify whether a certain value is a floating point value (marked as ”number”) or an integer
value (marked as ”integer”), where ”integer” must not be interpreted as the datatype ”int” like available in C/C++,
it just means it is a value without decimal places.
For these specifications, please refer to the sections discussing the respective request.
Examples
number 1, -2, 0, 4, 4.0, 0.001, -10.002, ....
integer 1, -2, 0, 4, -10
unsigned integer 1, 0, 4, 10
unsigned number 1, 0, 4, 10, 0.001, 14.1234
2.3.2 Date/Time
Information on date/time is always (and can only be) represented by a string. The format for these strings inside
this API has been defined as follows.
• Strings which include information on both date and time are always in RFC3339 format with time zone offset
or Zulu marker.
See Section 5.6 of RFC3339
Example 1: 2011-10-20T10:23:17+02:00 (UTC+2)
Example 2: 2011-10-20T08:23:17Z (UTC)
• Strings which only include information on the date are of the format yyyy-MM-dd.
• Strings which only include information on the time are of the format hh:mm:ss.
• If no information on the time zone is given, any date/time specification is considered to be in local time of
the PV system.
2.4 Requests
Currently, the only request protocol supported is HTTP.
+ Use HTTP-GET requests to query data from Solar API
2.4.1 Querying of API version

The highest supported version on the device can be queried using the URL
/solar_api/GetAPIVersion.cgi.
Listing 1: Object structure of GetAPIVersion response

object {
# Numeric version of the API.

# all Datamanager and Hybridmanager support only APIVersion 1
unsigned integer APIVersion ;
# URL under which the CGIs for the requests can be reached .
string BaseURL ;
# Compatibility version of current implementation ( except GetPowerFlowRealtimeData )

# THIS FIELD IS AVAILABLE AND MANDATORY SINCE
# Datamanager 3.9.1 -x
# Hybridmanager 1.7.1 -x
# FORMAT : MAJOR .MINOR - BUILD
# Major: compatibility range ( something big changed )
# Minor: feature range (new features added)
# Build: bugfix revision (only bugfixes applied )
6
string CompatibilityRange ;
}
Listing 2: Example: Complete response for GetAPIVersion request

{
" APIVersion " : 1,
" BaseURL " : "/ solar_api /v1/",
" CompatibilityRange " : "1.5 -9"
}
2.4.2 Addressing of devices

A specific device is identified by the string parameter DeviceId.
For Fronius Solar Net devices this string shall contain the numeric address of the targeted device.
Future generations of Fronius devices may also use non numerical addresses, so this API is designed to allow
for both.
2.5 Responses
The response will always be a valid JSON string ready to be evaluated by standard libraries.
If the response is delivered through HTTP, the Content-Type Header shall be either text/javascript or
application/json.
All JSON structures are described using Orderly JSON, a textual format for describing JSON data. Please refer
to the online documentation on https://github.com/lloyd/orderly/ for details.
Note that the definitions of some response bodies are not totally accurate, because there’s no (known) way to
express nodes named after values/channels (e.g. objects which are named ”PAC” or ”Power”). But each descrip-
tion is accompanied by an example which should clear up any uncertainty.
The contents of the response object will vary depending on the preceding request but it always contains a common
response header and a request body.

2.5.1 Availability
A request is listed as ”Available” if the response http code differs to 404 (not found). It does not relay to technical
compatibility nor functionality.
2.5.2 Common Response Header

The common response header (CRH) is present in every response. It indicates, among other things, whether the
request has been successful and the body of the response is valid.
Listing 5: Object Structure of Common Response Header

Table 1: Error Code Table
2.5.3 Request Body

The request body contains the actual data produced by the request and is therefore different for each request.
The object structures of the various response bodies will be detailed later in the description of the respective API
request.
2.6 Timeout
Up to 2 realtime requests are allowed to be performed in parallel with keeping a timeout of 4 seconds between
two consecutive calls.
Archive requests are not allowed to be performed in parallel and need to keep a timeout of 120 seconds between
two consecutive calls.
3 Enable/Disable
The Solar API’s enable/disable feature is available on GEN24 only.
The configuration to enable or disable the Solar API can be found in the WebUI under Communication - So-
lar API (1).
If the Solar API is disabled, a Solar API request will return with a 404-HTTP-error and the message ”Solar API
9
Figure 1: Solar API activation/deactivation
disabled by customer config” will be displayed.
Default enable/disable behaviour:
• For new devices with a bundle version of 1.14.1 or higher the Solar API is deactivated per default.
• For existing devices which are updated, the Solar API remains enabled.
• If a factory reset is performed with existing devices running a bundle version of 1.14.1 or higher, the Solar
API will be deactivated per default as well.
4 Realtime Requests
These requests will be provided where direct access to the realtime data of the devices is possible. This is cur-
rently the case for the Fronius Datalogger Web and the Fronius Datamanager.
In order to eliminate the need to specify each wanted value separately when making a request or querying each
value separately, so called ”Data Collections” were defined.
The values in these collections are gathered from one or more Fronius Solar Net messages and supplied to the
user in a single response to a certain request.
It may be the case that more values are queried from the device than the user is interested in, but the overhead
caused by these superfluous values should be negligible compared to the advantages this strategy provides for
the user.
If a device cannot provide some values of a DataCollection (e.g. because they are not implemented on
the device) then those values are omitted from the response.

The values EnergyReal_WAC_Sum_Produced and EnergyReal_WAC_Sum_Consumed represent the values

for the Smart Meter itself. The values EnergyReal_WAC_Minus_Absolute and EnergyReal_WAC_Plus_Absolute
represent the values for Solar.web. Now it depends where the Smart Meter is installed (Feed-In-Point or Consumption-
Path), so that either EnergyReal_WAC_Minus_Absolute is the same as EnergyReal_WAC_Sum_Produced or
EnergyReal_WAC_Sum_Consumed.

4.11 GetPowerFlowRealtimeData request

This request provides detailed information about the local energy grid. The values replied represent the current
state. Because data has multiple asynchronous origins it is a matter of fact that the sum of all powers (grid, load
and generate) will differ from zero.
This request does not care about the configured visibility of single inverters. All inverters are reported. Same for
batteries.

5 Archive Requests
5.1 Common
Archive requests shall be provided whenever access to historic device-data is possible and it makes sense to
provide such a request.
Of course, the Datalogger Web can only provide what is stored in its internal memory and has not been overwritten
by newer data yet. It can loose data, due to capacity reason. The number of days stored is dependent on the
number of connected units to log. This limitation is not present for Solar.web, provided that the Datalogger has
reliably uploaded the data.
Different from what is specified within the previously released drafts, there is only one CGI to access all historic
data. This CGI contains detailed, summed, error and events queries.
Call is http://<insert hostname or IP here>/solar_api/v1/GetArchiveData.cgi?<your query parameters>
The number of parallel queries is system wide restricted to 4 clients.
5.1.1 Availability

5.1.2 ChannelId
Each channel is handled and requested by name. Most of the channels are recorded in constant cyclic intervals
which can be set between 5 and 30 minutes. Only Digital_P owerM anagementRelay_Out_∗, InverterErrors,
InverterEvents and Hybrid_Operating_State are event triggered and may occure every time.

8 Frequently asked questions

1. The application I wrote for the Fronius Datalogger Web does not work with the Fronius Datamanager.
Why is that?
This is because we had to make some changes in the API to ensure compatibility with future devices.
Specifically the DeviceIndex parameter is now named DeviceId and the request URLs have been changed
to include an API version. For further details please refer to the latest version of the API specs.
2. Which data can I get?
Currently only realtime data from inverters, Fronius Sensor Cards and Fronius String Controls. Also some
information about the logging device itself is available.
Please refer to the API specs for further details.
3. Can multiple clients send requests to the API at the same time?
Yes, but the requests may take longer to complete.
4. Can I use this API at the same time as other services of the Datalogger Web / DataManager?
Yes. The datalogging, Solar.access/Solar.web connection, Webinterface, this API or any other service can
be used independently from the others.
5. Can the API calls be password protected?
No. The API is always accessible without authentication, regardless of the user or admin password set on
the Webinterface.
6. The API reports more inverters than I have, why is that?

This may be the case when the inverter number of an inverter is changed while the Fronius Datalogger Web
/ Fronius Datamanager is running. The logger then detects a new device but keeps the same device with
the previous inverter number in the system for 24 hours. This is due to the fact that the datalogger is caching
the devices for a certain time even if they are not present on the bus (e.g. to be able to display energy values
during the night when the inverters are offline).
Those ghost devices will disappear 24 hours after the have been last seen by the datalogger. Alternatively,
a reboot of the datalogger also clears the device cache and repopulates it with the currently present devices.
