1. Change Log

2. Scope

This document outlines the necessary commissioning procedure required to set up the SnapINverter series inverters to operate under a SAPN Dynamic Export agreement as a part of the SA Smart Homes Scheme. The commissioning steps outlined in this document are "additional" steps required on top of the standard inverter commissioning process. Please consult our other documentation for information on how to perform the standard commissioning steps.

IMPORTANT: This version 1.0 release of this document is ONLY valid for "single inverter" and "Inverter inbuilt” communication sites. Multi-Inverter sites are not yet possible with the “inverter inbuilt / native” solution. For multi-inverter sites an external 3rd party devices MUST be used instead. Multi-Inverter functionality will be released in the coming months once available.

The following Fronius Inverter series are relevant to this document:

• Fronius Primo SnapINverter series
• Fronius Symo SnapINverter series
• Fronius Eco SnapINverter series

3. General Information & Requirements

The SA Dynamic Export control function uses the IEEE 2030.5 based CSIP-AUS communication protocol to communicate from a Utility Server (SAPN) to the Fronius Cloud Aggregator. The Utility Server publishes varying "export limits' which the Fronius Aggregator retrieves and forwards to the relevant inverter (Client). For identification of the correct inverter, the protocol requires an LFDI (Long Form Device Identifier) to be created/issued for the inverter to then be supplied to SAPN.

Compatible inverters are listed on the CEC Approved Inverter list and have an entry under the column: "SOFTWARE CLIENT".

https://www.cleanenergycouncil.org.au/industry/products/inverters/approved-inverters

All Fronius Australia CEC listed inverters are compliant to the SAPN Dynamic Export capable requirements.

To complete a compliant install, the system MUST have the following:

• Fronius Smart Meter MUST be installed & commissioned in the system
• Datamanager is loaded with a min. firmware version ≥ 3.27.1-3.
• "Cloud Control” activated on the Datamanager WebUI
• A PV System in Solarweb is active with the assigned inverter
• Selected "Grid Operator" is "SA Power Networks"
• "Only tick to register PV system for Dynamic/Flexible Export sites controlled by Fronius" is ticked.

4. System Installation & Commissioning

Carry out the installation & commissioning process as per the standard process, for more information please consult with our online manuals: Datamanager Commissioning Guide

YouTube: https://www.youtube.com/watch?v=7G_pLLSI4UI

NOTE: After completion the Datamanager MUST be running the firmware version 3.27.1-3 or greater. If the firmware is lower than 3.27.1-3, please update the Datamanager via the WebUI firmware update trigger OR via Solarweb.

5. Onsite Inverter Setup

5.1 Set pre-commissioning Export Limit

Go to "Settings".

The Galvo interface displays system overview with real-time data, consumption, and consumption from the grid. The 'Settings' option is highlighted in the right-hand menu.

NOTE: A "service" password should have already been set when commissioning the Fronius Smart Meter.

5.2 Activate Cloud Control function

Scroll down to “Cloud Control” and tick "Allow cloud control for grid/utility compliance purposes”. Then click on the "tick" symbol to save.

The 'Cloud Control' section shows the option 'Allow cloud control for grid/utility compliance purposes' checked. A note explains that authorized operators can change output power if cloud control is enabled. Controlling priorities are listed.

IMPORTANT: If the Cloud Control “Allow cloud control for grid/utility compliance purposes” is NOT activated, the inverter will not be able to receive the export limit commands from SAPN.

6. Solar.web Cloud Setup

6.1 Create system in Solar.web

Create a new system in Solar.web as per the standard process, see how to here:

6.2 Input correct site Address & Installation Date

For tracking of system performance, the correct site address and installation date of the system is entered.

The Fronius SOLAR.WEB interface shows fields for 'PV system name', 'Datamanager', 'Address' (Country, State, Zip code, City, Street and house number), 'E-mail', 'Currency', and 'Time zone'. A callout box emphasizes ensuring installation date and address details match the actual PV system site address.

6.3 Select & fill in Grid connection details

Under "Grid operator" choose “SA Power Networks". Under "NMI – National Metering Identifier" enter site's 11 x digit NMI number. Tick the "Only tick to register PV system for Dynamic/Flexible Export sites controlled by Fronius” box.

IMPORTANT: Ticking the “Only tick to register PV system for Dynamic/Flexible Export sites controlled by Fronius." box registers the inverter system with the SAPN Utility server and creates the LFDI in the backgraound automatically. ONLY tick this box if the system is to be controlled by the Fronius cloud. i.e. Fronius internal native solution. DO NOT tick if controlled by Catch Relay, Zeco Marschall. The registration for these devices MUST be done by them directly. Also DO NOT tick this box for the SAPN Remote Disconnect functionality.

7. SAPN Device Registration Check

7.1 Check “Device registration” in Smart Install

Access Smart Install and log in. Complete the required details and information up to "Device registration". Check the "Device registration" tab for “Your device has been successfully registered".

The 'Device registration' confirmation screen shows a green tick (✔️) and the message 'Your device has been successfully registered'.

7.2 Run "Export Capability Test"

To run the "Export Capability Test" click on the “TEST EXPORT CAPABILITY” button. Progress will be shown of each test being performed.

IMPORTANT: the system MUST be exporting at least 500W for the test to PASS. If the export is below 500W, you will have to perform a test at another time OR turn loads off to enable the export to exceed 500W.

The 'Job Details' section lists steps like 'Export Limiting', 'PV Inverter', 'PV Panels', and 'Confirmation'. The 'Device registration check' is shown as complete. The 'Export Capability Test' section has a 'TO DO' status, with a button to 'TEST EXPORT CAPABILITY'. A note indicates the test can take up to 15 minutes.

A modal window for 'Export Capability Test' shows steps like 'Confirming connection', 'Confirming adherence to default limit', 'Sending test export limit', 'Confirming adherence to export limit', and 'Removing test export limit'. A green tick (✔️) indicates success for each step. The final state shows all green ticks, indicating the test is finished and PASSED.

When all GREEN ticks are present the test is finished and PASSED.
