Protective Devices
2.5.1
Anti-Islanding
When the local power distribution grid fails due to a fault or when the equipment is
shut down for maintenance operations, Aurora shall be physically disconnected
under safety conditions, so as to protect the people working on the grid, in full
compliance with the applicable prevailing national standards and regulations. To
avoid any possible islanding operation, Aurora is provided with an automatic
disconnection protective system called Anti-Islanding.
The AURORA PVI-6000-OUTD model is equipped with a state-of-the-art anti-
islanding protection system certified to the following standards and regulations:
AS4777.3-2005
2.5.2
Panel Ground Fault
This version of AURORA has been designed for use with panels with a floating
connection (positive and negative terminals not connected to ground). A
sophisticated ground protection circuit continually monitors the ground connection;
when it detects a ground fault, this circuit shuts down AURORA and turns on a red
LED on the front panel to indicate a ground fault condition. The AURORA
inverter is equipped with a terminal for the system grounding conductor; see
section 3.6 (step 3) for more details.
NOTE:
For more details of AURORA shutdown or possible causes of
malfunction, please refer to sections 5.3 and 5.4.
2.5.3
Further Protective Devices
Aurora is equipped with additional protections to guarantee safe operation under
any circumstances. The protections include:
constant monitoring of grid voltage to ensure that voltage and frequency
remain within the specified operational limits (in accordance with standards);
automatic power limitation control based on internal temperature monitoring
to avoid overheating (heat sink temperature ≤70°C [158°F]).
Many control devices are fitted to Aurora, making its structure redundant,
but at the same time ensuring a perfect and fully safe operation.
