Additional Protective Devices
The Aurora inverter 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 UL 1741 standard). For
more detail see paragraph 8.6.
•
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.
