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.

Operations Guide

4.1 GENERAL CONDITIONS

Before checking the operation of the equipment, it is necessary to have a thorough knowledge of

the instruments and the functions that have been enabled in the installation. The equipment

operates automatically without the aid of an operator; operating state is controlled through the

instruments.

The interpretation or variation of some data is reserved exclusively for

specialized and qualified staff.

During operation, check that the environmental and logistical conditions are correct. Make sure

that the said conditions have not changed over time and that the equipment is not exposed to

adverse weather conditions and has not been isolated with foreign bodies.

Power-One cannot be held responsible for damage to the equipment or the operator if it is the

result of incompetence, insufficient qualifications or lack of training.

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.

inverter found.


Page 38 of 80 Instruction Manual for AURORA CDD BCG.00613_AA

Part 4

Operations Guide

In this example five MICRO Inverters

have been found. Select the MICRO

Inverters to be associated with the

CDD (or deselect using the check box)

and press CONFIRM.

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.

5.1 ALARM CODES AND ERROR MESSAGES

The AURORA MICRO Inverter is capable of

communicating errors/warnings via radio to the

associated CDD device. Any messages received

and related codes can be checked on the display

Cause

The error appears when the inverter input

current exceeds the set overcurrent

threshold. This may be caused by:

a) sudden irradiance changes that may

generate input current surges into the

MICRO inverter

b) PV module incompatible with the

MICRO-inverter input characteristics

c) Faulty MICRO-inverter

The error is generated when the voltage at

the ends of the bulk capacitors exceeds the

Over Voltage threshold. This may be

caused by:

a) Grid voltage too high

b) Internal inverter fault

The error appears when the inverter output

current exceeds the internal inverter alarm

threshold.

This may be caused by:

a) High impedance grid with significant

voltage variations, even with small loads.

b) Internal inverter fault

Solution

a) The error occurs sporadically and no

action is required as the MICRO-inverter will

automatically reset to normal operation

b) It is necessary to verify that the

photovoltaic module specifications are

compatible with the inverter.

c) If conditions a) and b) have been verified

and the error persists, the malfunction may

be caused by an internal inverter fault

a) Check that the grid voltage is compatible

with the MICRO-inverter specifications. In

the event of highly abnormal grid voltage,

please contact your grid operator to address

the problem.

b) If no problems are found when checking

the grid voltage, the alarm may be caused

by internal inverter faults.

a) Check that the grid voltage is stable,

mainly upon:

- loading with high current peak loads.

- maximum power generation of the PV

system

If the grid voltage is unstable, verify the

appropriate sizing of the line cable/s, and, if

correct, please contact your grid operator to

address the problem.

b) If no problems are found when checking

the grid voltage, the alarm may be caused

by internal inverter faults

the power that the inverter must supply, as

the internal inverter temperature is affected

by the heat dissipated internally by its

components. This may be caused by:

a) Failure to observe the installation

conditions

b) Internal inverter fault

The error is generated when a ground

leakage current is detected in the DC

section of the system. This may be caused

by:

a) PV module ground leakage

b) Internal inverter fault

The error is generated if the DC component

of the current supplied to the grid exceeds

the threshold set by the country of

installation’s applicable regulation. In any

case, the inverter will automatically try to

reconnect to the grid. This may be caused

by:

a) Sporadic recurrence of this error is a

sign of large grid distortions or sudden

changes in irradiance.

b) Systematic recurrence of this error may

be due to an inverter fault.

a) The alarm may occur during inverter initialization

and is caused by the initialization

of communication between the CDD and

the MICRO inverters.

b) Systematic occurrence of this error may

Solution

a) Verify the installation conditions

(exposure to sunlight) and check that air

flow to the MICRO inverter is not

obstructed, so as to permit cooling of the

device. Check that the ambient temperature

measured around the MICRO inverter does

not exceed the limits set in the technical

data.

b) Verify the MICRO-inverter temperature

readings (see the Internal Web Server

section in the CDD manual). If one of the

temperatures remains at a value which is

not compatible with the environmental conditions

(e.g. -40°C internal temp. reading

with 20°C effective ambient temperature),

the alarm may be due to internal inverter

causes.

See the “Verification of ground leakage” and

“Measuring the insulation resistance”

sections for information on how to perform

checks and measurements.

a) If the measured insulation resistance

value is less than 1KΩ, the PV module has

a ground leakage that prevents the grid

connection of the inverter. In this case the

PV module must be replaced.

b) If the measured value exceeds 1KΩ, try

connecting the MICRO-inverter to a

different PV module. If the error persists,

the alarm may be caused by internal

inverter faults. To perform this test, the

MICRO-inverter Ground Fault condition

must be reset via the Web Server.

a) Verify the grid parameters and, if the grid

voltage is strongly distorted, please contact

your grid operator to address the problem

If the grid voltage is stable, the error may

also be due to sudden irradiance variations.

In this case, the inverter will automatically

try to reconnect to the grid and no actions

are required to solve the problem.

b) If the grid voltage is stable, yet the error

systematically persists, the malfunction may

be caused by an internal inverter fault

a) The alarm will automatically reset upon

connection of the inverter to the grid, and no

actions are required to solve the problem.

b) If the error systematically persists, the

malfunction may be caused by an internal

The alarm is generated when the grid

standard (selected on the CDD during

installation) has not been correctly set on

the MICRO inverters. This may be caused

by:

a) communication problems while setting

the grid standard for the MICRO-inverter

from the CDD:

b) poor irradiance while setting the grid

standard for the MICRO-inverter from the

CDD: MICRO-inverters are directly

supplied by the voltage generated at the

module, and poor irradiance may cause

inverter shut-downs

The set grid standard is not compatible with

the firmware installed on the MICROinverter.

This condition may be generated if

a MICRO-inverter is replaced.

This alarm is displayed when the input

voltage generated at the PV generator is

outside the allowed range given in the

technical data. This may be caused by:

a) Poor irradiance

b) Possible shadows that may darken the

module during part of the day.

b) PV module incompatible with the

MICRO-inverter input parameters

d) Internal inverter fault

This alarm is generated when one or more

grid parameters lie outside the permitted

range set by the country of installation’s

grid standard. The error code will be

followed by a suffix in brackets indicating

the grid parameter out of range:

(UV) Grid voltage below the set lower limit

(OV) Grid voltage above the set upper limit

(UF) Grid frequency below the set lower

limit

(OF) Grid frequency above the set upper

limit

a) Verify on the Internal Web Server (as

described in the CDD manual), the radio

communication quality on each MICROinverter

(values above 60% indicate good

reception). If the quality of the received

signal is good re-configure the installation,

otherwise consider installing the CDD

device in a different position to ensure

better radio signal quality.

b) System configuration must be carried out

in good irradiance conditions, in order to

guarantee the correct operation of the

MICRO-inverter and to prevent the risk of

shut-downs due to insufficient input voltage

generated by the PV module.

The firmware in the MICRO-inverter/s in the

installation must be updated to a compatible

version. Firmware updates are performed

via the Internal Web Server (see the CDD

manual), with the software package

obtained from Power-One Service

a) Wait for appropriate irradiance to

guarantee correct operation of the inverter

b) Verify that no shadows are present on

the PV module when the error is generated

c) Verify that the PV module voltage

characteristics are compatible with the

inverter input specifications.

d) If the above checks have yielded positive

results, yet the error persists, the

malfunction may be caused by the MICROinverter.

If the error is generated only on one of the

installation MICRO-inverters, this may be

due to an inverter fault.

If the alarm is generated at multiple

inverters in the installation, check the grid

voltage for instabilities in any of the 4

parameters monitored by the inverter. If

anomalous values are detected, verify the

sizing of the AC line conductors. In case of

correct sizing, please contact your grid

operator to address the problem.
