  1. APPLICATION AREAS FOR INTEGRATED INTERFACES

  2. DATA COMMUNICATION APPLICATIONS • FRONIUS SYMOMaximum flexibility for the applications of tomorrow. • FRONIUS GALVOThe future-proof inverter for small self-consumption systems.

  3. The Fronius Galvo and Fronius Symo inverters have numerous permanently integrated interfaces that can be used for a variety of practical applications. • The following slides provide an overview of the various application possibilities • How is the inverter connected to the internet? • How can data be saved locally? • How can the inverter be updated? • How can loads be controlled? • How can the inverter send signals? • How can the inverter be controlled remotely? • How is a dynamic power reduction realized? • How can devices from third-party suppliers be integrated? • How are multiple inverters connected?

  4. OVERVIEW OF INTEGRATED INTERFACES EXTERNal INPUT (F.E. fOr A S0-METer) FRONIUS Solar.Net IN FRONIUS Solar.Net OUT USB INTERFACE FLOATING RELAY OUTPUT Digital INPUTS AND OUTPUTS (I/Os) (ONE OF THEM IS A DIGITAL OUTPUT FOR energYmanAgement) Ethernet WLAN AntennA 4 4 6 2 6 1 5 2 3 7 7 1 5 3 8 8

  5. HOW IS THE INVERTER CONNECTED TO THE INTERNET? • The inverter can be connected directly to the router via LAN (Ethernet) or WLAN • When using WLAN, a cable connecting the inverter to the router is not required • Using the internet connection gives the user access to the free Fronius Solar.web online portal as well as Fronius Solar.TV and the Fronius Solar.web App • The connection to Fronius Solar.web ensures that rapid technical support can be provided in the event that servicing is required • Register for Fronius Solar.web at: www.solarweb.com

  7. HOW CAN DATA BE SAVED LOCALLY? • Data can be saved locally using a USB stick • Simply insert a conventional USB stick and the data from the inverter will be stored on the stick • The data is saved in a CSV file so that it can easily be processed in Microsoft Excel, for example

  8. NOTE: SETTINGS ON THE DISPLAY ACCORDING TO OPERATING INSTRUCTIONS

  9. HOW CAN THE INVERTER BE UPDATED? • Software updates ensure that the latest version of the software is installed on the inverter • The software can be updated using a conventional USB stick; the inverter has an integrated USB interface for this purpose • Save the new software onto the stick, insert it into the inverter and perform the update • No additional hardware is required for the update process

  10. Download the latest software from: www.fronius.com– Solar Electronics – Info & Support –Software Downloads Maximum size of the USB stick: 65 x 30 mm NOTE: SETTINGS ON THE DISPLAY ACCORDING TO OPERATING INSTRUCTIONS

  11. HOW CAN LOADS BE CONTROLLED? • The inverters can turn consumers on and off automatically using power thresholds • If the output level of the photovoltaic system exceeds the preset ON value, the consumer will be switched on • If the output level of the photovoltaic system falls below the preset OFF value, the consumer will be switched off again • Consumers can be connected to the Fronius Galvo and Fronius Symo inverters in two different ways: • using a digital output • using a floating relay contact

  12. The inverters can turn consumers on and off automatically using power thresholds • Variant 1 – using a digital output:Heater example: ON at 2 kW, OFF at 1.5 kW, minimum running time: 60 mins NOTE: SETTINGS ON THE WEB INTERFACE OF THE INTEGRATED WEB SERVER L I/0 1 GND Contactor N

  13. HOW CAN LOADS BE CONTROLLED? • The inverters can turn consumers on and off automatically using power thresholds • Variant 2 – floating relay contact: • Direct switch on from max. 30V and 1A DC – or max. 250V and 4A AC • Swimming pool pump example: ON at 1 kW, OFF at 0.5 kW NOTE: SETTINGS ON THE DISPLAY ACCORDING TO OPERATING INSTRUCTIONS Pin 3 (NO contact) Pin 2 (root) Supply, e.g. 230V AC N

  14. HOW CAN THE INVERTER SEND SIGNALS? • Audiovisual alarm devices can be connected to the relay contact • When an error occurs, the inverter switches the relay contact and the signal starts • The relay contact can be used either as an alarm device or to connect a load NOTE: SETTINGS ON THE DISPLAY ACCORDING TO OPERATING INSTRUCTIONS Pin 2 (root) Pin 3 (NO contact) Supply, e.g. 230V AC N

  15. HOW CAN THE INVERTER BE CONTROLLED REMOTELY? • The ripple control receiver can be connected directly to the inverter so that the PSC can control it remotely • Power reduction and power factor can be controlled using the digital inputs for the ripple control receiver • Digital inputs can be configured by the user

  16. NOTE: SETTINGS ON THE WEB INTERFACE OF THE INTEGRATED WEB SERVER Up to eight inputs can be configured, one output is available for feedback to the PSC.

  17. HOW IS A DYNAMIC POWER REDUCTION REALIZED? • A S0-meter can be connected directly to the inverter, in order to take self-consumption into account for feed-in limits (f.e. 70 % of the kWp, max. 5 kW or similar) • The meter can connected at the feed-in point or directly in the consumption path • The feed-in limit and the number of impulses can be set individually NOTE: MORE DETAILED INFORMATION ON THE INSTALLATION AND SETUP CAN BE FOUND IN THE MANUAL OF THE FRONIUS DATAMANAGER

  18. NOTE: SETTINGS ON THE WEB INTERFACE OF THE INTEGRATED WEB SERVER S0-meter

  19. HOW CAN DEVICES FROM THIRD-PARTY SUPPLIERS BE INTEGRATED? • The open interfaces permit easy communication between the inverters and third-party components • Integrating the photovoltaic system into higher-level energy management or home automation systems is therefore a simple matter • The Fronius Galvo and Symo offer the following open interfaces via Ethernet or WLAN: • JSON • Modbus TCP • For example: Integration into home control system with the LoxoneMiniserver to effectively maximise self-consumption

  20. WLAN Network cable or WLAN Router or switch Parallel operation of Fronius Solar.web and integration into home control system possible.

  21. HOW ARE MULTIPLE INVERTERS CONNECTED? • Multiple Fronius inverters can be connected to each other via the Fronius Solar Net ring, a bus system configured as a ring. • The data connection for Fronius Solar.Net nodes uses a 1:1 connection with 8-pin data cables and RJ45 plugs. A termination plug is plugged in at each end of the ring. • The Fronius Galvo and Fronius Symo inverters are equipped with the required interfaces (Fronius Solar.Net IN and Fronius Solar.Net OUT). • In a Fronius Solar Net ring, only one Fronius inverter with an integrated datalogger is required; the remaining inverters must be "light" variants. NOTE: MORE DETAILED INFO ON CABLING CAN BE FOUNDONLINE IN THE GUIDELINES ONDATCOM CABLING.
