Data transmission and control
The MICRO inverters are monitored remotely through an advanced communications system based
on a wireless connection and the CDD device. In addition to local monitoring of the system, it is
possible to have remote data visualization through an internet access to Power-One’s AURORA®
VISION web portal.
Single photovoltaic module management benefit
There are many advantages of having each MICRO inverter monitor a single photovoltaic module:
Capability of viewing each module’s production
Possibility of controlling when to clean each module, as necessary
Ease of service interventions from the possibility of singling out individual modules or inverter that
are down.
Preservation of production even if there is a malfunctioning module or inverter

EVICES
7.1.2.1
A
nti-Islanding
In accordance with required national standards and laws, in the event of a local grid outage by the
utility, or when the grid equipment is switched OFF for maintenance operations, the inverter must
be physically and safely disconnected, to ensure protection of personnel working on the grid. To
prevent possible islanding, the inverter has an automatic protective disconnection system called
“Anti-Islanding”.
7.1.2.2
G
round fault in the photovoltaic modules
An advanced ground fault protection circuit continuously monitors the ground connection and
disconnects the inverter if a ground fault occurs, indicating this condition by means of the red GFI
LED on the LED panel.
7.1.2.3
Protective devices
The inverter is equipped with additional protective devices to facilitate safe operation. These
protective devices include:
Continuous monitoring of the grid voltage to ensure the voltage and frequency values stay within
operating limits;
Control of internal temperatures to automatically limit the power if necessary to ensure the unit
does not overheat (derating).
