Brand and model of photovoltaic panels

WARNING: In some cases, national and local regulations make it
obligatory for one of the DC input terminals to be connected to the
system ground. Carefully refer to the national standard in order to ground
the inverter input correctly.
A specific connector allows connecting one and only one of the two DC input
terminals (positive or negative) to the ground. A sophisticated ground protection
circuit constantly monitors the ground connection, deactivates AURORA in the
event that a ground fault is detected, and indicates the ground fault condition
through a red LED located on the front panel. The AURORA inverter is equipped
with terminals for the system ground conductors.
For further information about the grounding of terminals and protections, refer to
section 3.4.9
NOTE: For further details about disconnecting AURORA or about the
causes of malfunction, refer to paragraphs 5.3

Additional protections

AURORA is equipped with additional protections in order to ensure its safe
operation under any circumstances. These protections include:
continual monitoring of the grid voltage to guarantee that the voltage and
frequency values remain within the operational limits;
internal temperature control, in order to limit power automatically, should this
be necessary to ensure that the unit does not overheat (heat sink temperature
≤70°C [158°F]).
AURORA numerous control devices render its structure redundant, ensuring
the absolute safety of its operation.
