2. SCOPE
This document aims to provide instructions on how to setup the Fronius SnapINverter series inverters for
compliance to the AS/NZS 5033 Earth Fault Alarm requirement.
AS/NZS 5033 stipulates the following requirement for an Earth Fault Alarm where the PV Array is >120Vdc:
The alarm system shall continue repeating its operation at least at hourly intervals until the earth fault is corrected or until
the fault is acknowledged.
The earth fault alarm shall be at least one of the following types:
(a) Remote communication (such as email, SMS or similar).
(b) Local indication
The Fronius SnapINverter series inverters are able to provide a "Remote Communication" option via Email or
SMS and "Local indication" option via a local audible or visible alarm.
3. EARTH FAULT ALARM - REMOTE COMMUNICATION
The remote communication functionality uses e-mail messages in the form of alarm notifications communicated
via existing Internet connection to nominated contacts. The Datamanager creates the Earth Fault error and
transmits that to Solarweb. Solarweb then sends the error in an Email to the nominated contacts.
3.1 Requirements
For the remote communication option to be used, it is required to make use of Fronius' online platform
Solar.web, This means the PV system needs to be connected to the Internet either via Fronius Datamanager
card (in the inverter) or Fronius Datamanager box (external).
Basic requirements for enabling this functionality are:
/
Datamanager fully commissioned and operational,
/
Fully functional internet connection of the inverter,
/
System configured & registered in Fronius Solar.web.
In the event of a detected earth fault, notification of an Earth Fault is sent to the nominated contacts every hour
until the fault is acknowledged in Solarweb.
