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.


The following information can be viewed by navigating in the menu:

• Operating status of each MICRO Inverter and statistics

• Operating status of the connection to the Internet/local network

• Alarm messages and fault indicators The display offers user friendly and intuitive use with the option of navigating through the various menus by means of buttons on the side of the CDD.

1.4.4 OPERATING DIAGRAM The diagram for this system shows how several wireless Power-One devices are connected to the CDD device, which in turn 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 AURORA EASY VIEW web portal, described in Part 4.

PART 4 OPERATIONS GUIDE

of 80 Instruction Manual for AURORA CDD BCG.00613_AB Part 4 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.


4.2.2 ACQUISITION OF MICRO INVERTERS Open the CDD local web server page on your browser as described in section 4.2.1 above.

A browser activated with JavaScript must be used in order to correctly view the Local Web Portal pages.

Select Config and choose Acquisition Wizard from

the drop-down menu.


This Acquisition Wizard requires authentication. Enter the default access credentials: username: admin password: admin Press OK

After entering the username and password, you will be at Step 1 of the acquisition procedure for the MICRO Inverters present in the system.

Click on START ACQUISITION to begin scanning


Upon completion, a list of the MICRO Inverters will be displayed and include the MAC RF (MAC Radio Frequency Address), SN (Serial Number) and Signal (radio signal quality indicator) for each inverter found.

There is no timeout for the acquisition procedure. Press STOP ACQUISITION when all the MICRO Inverters have been found.


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.

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.


The next step of the Acquisition Wizard will require selection of a country standard and the choice of 208V or 240V.

The CDD will set the standard selected on each of the MICRO Inverters in communication. Do not set network standards that do not match those of the country of installation!

Selection and confirmation of the country code will display the last step for CDD registration.

Make a selection from the drop-down menu and click CONFIRM to continue.


The last step involves registration of the CDD on the Aurora Vision web portal.

The link will take you to the Welcome page.

Click on the link to register the CDD on the Aurora Vision Web portal.

Select Register My Microinverters


The registration procedure is described below in section 4.3.1 and requires the router to be connected to Internet. It is recommended to complete registrations for all new installations and replacement parts. However, you can complete the acquisition process without registering the CDD on the Aurora Vision web portal, (or register later), by clicking on PLEASE CLICK HERE TO COMPLETE, as shown below.

Click on the item Home in the menu to complete the procedure.

PART 5 TROUBLESHOOTING

of 80 Instruction Manual for AURORA CDD BCG.00613_AB Part 5 Troubleshooting

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 of the CDD device Table 5-1 below provides a description of the alarm messages and error codes.

Table 5-1: Alarm Messages and Error Codes

Alarm Messages

Code displayed

Cause Solution

Input OC E001 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

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

Vbulk OV E004 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.

Output OC E006 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


Alarm Messages

Code displayed

Cause Solution

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 Server section in the CDD manual). If one of the temperatures remains at a value which is not compatible with the environmental con-ditions (e.g. -40°C internal temp. reading with 20°C effective ambient temperature), the alarm may be due to internal inverter causes.

Ground fault

E018 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

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.

DC Injection

E023 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) 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

Internal Error

E024 a) The alarm may occur during inverter ini-tialization and is caused by the initialization of communication between the CDD and the MICRO inverters. b) Systematic occurrence of this error may

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

be due to an inverter fault. inverter fault

Country Mismatch

E050 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

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 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.

Country Not Comp

E051 The set grid standard is not compatible with the firmware installed on the MICRO-inverter. This condition may be generated if a MICRO-inverter is replaced.

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

Vpanel Problem

W001 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

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 MICRO-inverter.

Grid Fail W003 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

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.

Cause Solution

Vbulk UV W011 Internal fault of the booster circuit inverter Contact Power-One Service.

Comm warning

W025 The alarm is generated when the CDD device does not receive messages from the MICRO-inverter for more than 5 minutes. This may be caused by non-optimal positioning of the CDD.

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)

Comm fault
