escription of the plant using MICRO-inverter
The plant is composed by a group of MICRO-inverters that convert direct electric current from a photovoltaic module into alternating electric current and feeds it into the national grid.
Photovoltaic panels transform energy from the sun into direct current
(DC) electrical energy; however, to feed the grid and so that this energy can be used, it has to be transformed into alternating current (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.
When used in parallel with the grid, the alternating current generated by the inverter flows directly into the domestic electrical circuit, which is in turn connected, through a load distribution panel, to the grid.
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 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 electric utility regulations, the power produced can be sold to the grid or credited towards future consumption, bringing about a saving of energy.
C
haracteristics of a system employing MICRO-inverters
Unlike systems subdivided into strings controlled by one or several inverters, plants 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 every single photovoltaic module, consequently optimizing production as much as possible.
Further there are no exposed high voltage DC wires with this system design. This enables firefighters to work safely should the need arise.

perating diagram
The diagram for this system shows how several wireless Power-One devices are connected to the CDD device, which turns interacts via WiFi or ethernet with a PC or a router connected to the internet.
The system can be managed and monitored from a PC or Smartphone with internet access if the device is registered at the Power-One AURO-
RA EASY VIEW web portal.
N
otes on the sizing of the system
Decisions about how to structure a photovoltaic system depend on a certain number of factors and considerations to make, such as for example, the type of panels, the availability of space, the future location of the system, energy production goals over the long term, etc.
A configuration program (stringtool.power-one.com) that can help to correctly size the photovoltaic system is available on the web site of Power-
One (www.power-one.com).

eneral conditions
Before checking the operation of the equipment, it is necessary to have a thorough knowledge of the INSTRUMENTS chapter 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.
The incoming voltage must not exceed the maximum values shown in the technical data in order to avoid damaging the equipment.
Consult the technical data for further details.
Even during operation, check that the environmental and logistic conditions are correct (see installation chapter).
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.

ommissioning of the plant
On completing the installation phase, the CDD will be connected to the PC.
The commissioning of the plant consists in the acquisition of the MI-
CRO-inverters by the CDD, which is carried out by means of a PC or
Tablet connected via a WIFI network or Ethernet cable, using a Local
Web Portal inside the CDD.
A
cquisition of MICRO-inverters
Enter the IP address acquired previously (during the installation phase) in the URL address bar of your browser, and wait until the page is displayed.
In order to correctly view the Local Web Portal pages must be used a browser with activated Javascript.
In the drop-down menu select the item Config>Acquisition Wizard
This submenu requires authentication.
The pre-set access credentials are: username: admin password: admin
After entering the password you will access the pages for acquisition of the MICRO-inverters present in the system.
Click on the icon START ACQUISITION to start scanning.
There is no timeout for the acquisition procedure, and it must be stopped by the user once the MICRO-inverters have been found.
- 30 -
Operation 7
In the example 5 MICRO-inverters have been found, and for each one of them the MAC RF (MAC radio frequency Address), SN (Serial Number) and Signal (radio signal quality indicator) are indicated.
During acquisition of the system the installer must check that all the
MICRO-inverters installed have been recognised successfully. This can be done by comparing the MAC ADDRESS detected with the ones indicated on the cover, on the carrier box or on the removable adhesive labels used to redirect the system map.
MICRO-inverters with a Signal less than 40 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.
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.
Select the MICRO inverters to be associated with the CDD and press
CONFIRM
The next step is to define the network standard for the country of installation (Country Standard).
The CDD will set the standard selected on each of the MICRO-inverters in communication with it.
Do not set network standards that do not match those of the country of installation!

Cause
The error appears when the inverter input current exceeds the set overcurrent threshold.
This may be caused by: a) sudden irradiation changes that may generate input current surges into the MICRO inverter b) PV module incompatible with the MICROinverter input characteristics c) Faulty MICRO-inverter
Solution a) The error occurs sporadically and no action is required as the MI-
CRO-inverter will automatically reset to normal operation b) It is necessary to verify that the photovoltaic panel 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
Vbulk OV E004
Output OC E006
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 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.
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 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
OverTemp E014 High internal temperature recorded by the inverter. This parameter depends in part on 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 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 Serversection 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.

Maintenance 8
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.
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 irradiation.
b) Systematic recurrence of this error may be due to an inverter fault.
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 irradiation 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 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 be due to an 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 inverter fault
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 irradiation while setting the grid standard for the MICRO-inverter from the CDD:
MICRO-inverters are directly supplied by the voltage generated at the panel, and poor irradiation may cause inverter shut-downs a) verify on the Internal Web Server (as described in the CDD manual), the radio communication quality on each MICRO-inverter (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 irradiation 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 set grid standard is not compatible with the firmware installed on the MICROinverter.
This condition may be generated if a MICROinverter 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 irradiation b) Possible shadows that may darken the module during part of the day.
b) PV module incompatible with the MICROinverter input parameters d) Internal inverter fault
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 irradiation 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 panel 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 bythe MICRO-inverter.

If the error is generated only on one of the installation MICRO-inverters, this may be due to an inverter fault.
This alarm is generated when one or more grid parameters lies 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
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.
Internal fault of the booster circuit inverter Contact Power-One Service.
T he alarm is generated when the CDD device does not receive messages from the MICROinverter for more than 5 minutes. This may be caused by non-optimal positioning of the CDD.
The alarm is generated when the CDD device does not receive messages from the MI-
CRO-inverter for more than 15 minutes. This may be caused by non-optimal positioning of the CDD.
The alarm is generated when an external shutdown command has been sent to the
MICRO-inverter.
Consider a new installation position that ensures better communication between the CDD device and the MICRO-inverters. Use the CDD
Internal Web Server to verify the signal quality (refer to the CDD manual for information on the Internal Web Server)
