Part 1 Introduction and Safety

1.4 SYSTEM INTEGRATION

1.4.1 THE MICRO INVERTER SYSTEM

This system is composed of a group of MICRO Inverters that convert direct electric current from a
photovoltaic module into alternating electric current and feeds it into the electric grid.

Photovoltaic modules transform energy from the sun into direct current (DC) electrical energy
(through a photovoltaic field, also called photovoltaic module). In order to use it, it is necessary to
transform the type of current into alternating “AC”. This conversion, known as DC to AC inversion,
is made efficiently without using rotating parts and only through static electronic devices.

In order to allow inverter operation in safe thermal and electrical conditions, in the event of
adverse environmental conditions or unsuitable input voltage values, the unit automatically
reduces the value of the power fed into the grid. This way the solar energy system compensates for
the energy drawn from the utilities connected to the grid to which it is linked. The solar energy
system therefore powers all connected electrical devices, from lighting to household appliances, etc.

When the photovoltaic system is not supplying sufficient power, the power needed to ensure
normal operation of the connected electrical devices is drawn from the national grid. If, on the other
hand, excess power is produced, this is fed directly into the grid, so becoming available to other
consumers.

In accordance with local and national regulations, the power produced can be sold to the grid or
credited towards future consumption, so bringing about a saving of money.

1.4.2 CHARACTERISTICS OF MICRO-INVERTERS

Unlike systems subdivided into strings controlled by one or several inverters, systems of this sort
are built for the incorporation of a MICRO Inverter for each photovoltaic module

.

Each MICRO-Inverter works independently of the others, thus its own photovoltaic module supplies
the maximum power available to the grid. This setup enables a direct control over the production of
a single photovoltaic module, consequently optimizing production as much

as possible.

1.4.3 DESCRIPTION OF THE CDD

The Power-One devices (MICRO Inverters) associated with the CDD are monitored using CDD
display, the CDD web server interface, or from the Aurora Vision monitoring portal.

The display for the CDD permits simultaneous monitoring of all the devices associated to it.

result of incompetence, insufficient qualifications or lack of training.

bodies.

4.2 COMMISSIONING

On completion of the installation and configuration in Part 3, the CDD will be connected to the PC.
The commissioning of the system consists in the acquisition of the MICRO Inverters by the CDD.
This is carried out using a PC or Tablet, connected via a WIFI network or Ethernet cable, to the CDD
local web server.

4.2.1 ACCESSING THE CDD LOCAL WEB SERVER

In order to access the CDD local web server, the PC or Tablet must be connected to the same local
network, i.e. through the same Ethernet or WiFi router, or connected directly to the CDD using a
cross Ethernet cable.

To access the CDD local web server, enter the IP address acquired previously (section 3.4.3.1, IP
Address View) in the URL address bar of your browser, and wait until the Power-One page is
displayed.

During acquisition of the system the installer must check that all the MICRO Inverters installed have
been recognized successfully. This can be done by comparing the MAC addresses detected with the
ones indicated on the cover or the carrier box of each inverter, or using the system map created
with the removable adhesive labels.

MICRO Inverters with a signal less than 25 should not be assigned, as they would be too
weak. In this case it is necessary to assess whether to install the CDD in a new position or to
use a signal repeater (REP).

If the MICRO Inverter has the Serial Number xxxxxx this means that the CDD has not yet
acquired the Serial Number for that MICRO Inverter. Wait a few minutes and then repeat the
scan by going back to the Configuration menu and selecting Start Acquisition.
