APPLICATION AREAS FOR INTEGRATED INTERFACES

DATA COMMUNICATION APPLICATIONS FRONIUS GALVO The future-proof inverter for small self-consumption systems. FRONIUS SYMO The compact three-phase inverter for maximum flexibility.

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 be controlled remotely? How can the inverter send signals? How can devices from third-party suppliers be integrated? How are multiple inverters connected?

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

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

NOTE: SETTINGS ON THE DISPLAY ACCORDING TO OPERATING INSTRUCTIONS

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

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

NOTE: SETTINGS ON THE WEB INTERFACE OF THE INTEGRATED WEB SERVER 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 GND I/0 1 Contactor N

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 OPERATING INSTRUCTIONS Pin 2 (root) Pin 3 (NO contact) Supply, e.g. 230V AC N

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 OPERATING INSTRUCTIONS Pin 2 (root) Pin 3 (NO contact) Supply, e.g. 230V AC N

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

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.

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: JSON Modbus TCP For example: Integration into home control system with the Loxone Miniserver to effectively maximise self-consumption

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

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. DATCOM CABLING.
