Fronius Solar API (JSON)

The Solar API is an open REST API that enables applications to read data directly from the inverter via the network. The inverter (or Datamanager 2.0) serves as the central communication unit and makes data such as power, voltage, current etc. available. Data from components connected to the inverter such as Smart Meter, Ohmpilot, String Control etc. can also be queried. All data is returned as JSON objects.
