3 Description

3�1 Identication

The inverter can be identied on the basis of the information provided on the nameplate (see Section 3.5).

3�2 Functionality

Automatic operation

Inverter operation is completely automatic and depends on the available output of the PV generator. If there is enough power, the inverter starts mains operation and feeds into the power grid. If there is not enough power available from the PV generator, the inverter disconnects from the grid and shuts down.

Operation

The graphics display with three function keys allows convenient inverter operation and reading of all important operating data. The graphics display is only switched on when the DC input voltage is high enough.

The DC disconnector can be used to switch the PV generator on or off at any time. The components of the inverter remain live even when the DC disconnector is switched off.

Remote monitoring

For the purpose of monitoring the PV plant remotely, Ethernet and RS485 interfaces are provided. The inverter can be directly connected to the internet via Ethernet (MaxView). The inverter is equipped with status signaling contacts for displaying the operating status remotely.

Extended functions

The inverter has functions for grid monitoring, limitation of output and reactive power control. These can be congured with additional software.

Remote controlled output limitation and reactive power control can be achieved using the MaxWebxp and MaxRemote accessory components.

Ventilation

The inverter is air cooled. Fans draw in the air through the air inlet on the right-hand side of the inverter. Then the air is conducted across the internal cooling elements. The air outlet is on the left-hand side of the inverter.

3�3 Safety installations

Surge protection

The inverter is tted with surge arresters (varistors) at its input and output. Each MPP tracker (plus and minus connections) is equipped with a surge arrester. On the AC side, each mains phase has a surge arrester (for details on the surge arresters tted, see Section 11).

When designing the PV system, it may be necessary to provide additional external lightning protection.

Fault current monitoring

The inverter has an AC/DC sensitive leakage current sensor which monitors the stray currents occurring on the generator side. This sensor can distinguish between the operational capacitive stray currents (caused by capacities of the PV modules to ground) and leakage currents (caused by touching a pole of the PV generator). If the inverter detects an excess in the permissible leakage or stray currents, it will disconnect from the grid.

Functions for current and output limitation

When it is needed, the inverter limits the DC feed-in current, the output power and the output current.

Temperature limitation

At ambient temperatures of more than 45°C the equipment temperature may reach more than 80°C. In such cases, the maximum in-feed power is temporarily reduced. When the equipment temperature rises above 85°C, the inverter disconnects from the grid.

Contact Description

NA21 Control line terminal / external shutdown of MPP trackers 1 and 2 NA22 Control line terminal / external shutdown of MPP trackers 3 and 4 NA1 Neutral conductor terminal

For as long as the signal (phase voltage) of the external grid monitoring system is live on the NA21 / NA22 contacts, the respective MPP trackers can feed into the mains grid. When the signal stops, the K1/K3 or K3/K4 (see Section 3.6) grid relays of the inverter are opened. This immediately disconnects the inverter from the grid.

The control line of the external grid monitoring system should be connected to the two contacts, NA21 and NA22, using a bridge. When only one contact is connected, only that one MPP tracker will feed into the grid. When the status signaling contacts are in use (see Section 5.6) the external shutdown function cannot be used.

6�3 Auto test

The auto test (only available in the "Italy" country setting) checks the inverter's grid monitoring function. The auto test consists of 7 test steps in which the triggering behavior is checked when the voltage and frequency limits are exceeded.

In the auto test the limit value is gradually changed until it reaches the triggering threshold (i.e. the current measured value). If the grid monitoring function is working, the inverter triggers the grid monitoring action. For each step of the test, the graphics display shows the current reading, the trigger value, the trip time and the set limit. During the test of the frequency limits, the activation status of the limit value is also displayed.

The auto test is performed automatically. Following completion of the auto test, the inverter returns to normal operation. If an error occurs or irradiation is too low during the auto test, the auto test is aborted. In this case the message "Auto-test aborted" is shown on the display. The auto tests lasts approximately 5 minutes.

Requirements

 The auto test should be carried out when there is sufcient solar irradiation, i.e. not

at dusk or when there is extensive cloud cover.

 Before starting to dismount the inverter, the inverter must be fully discon-

nected in accordance with the procedure described in this chapter.

WARNING! Risk of injury from electric arc!

Dangerous electric arcs could occur when removing live DC input conductors.

 Switch off the DC disconnector before removing the DC input

conductors.

Procedure

1. Disconnect the AC power supply to the inverter (switch off the external AC circuit breaker).

– The "No grid" status message is shown on the inverter.

2. Switch off the DC disconnector at the inverter.

Figure 44 Switching off the DC disconnector

3. Use a size 2 screwdriver to remove the locking clips on the DC plugs.

4. Pull out the DC input conductors to fully disconnect the inverter from the PV generator.

5. Remove the cover of the inverter as described in Section 5.1.

6. Use a suitable voltage detector to check that all terminals are free from voltage.

– When all terminals are free from voltage you can remove the AC input conductor

and all communication cables.

7. Fit the cover of the inverter.

8. Remove the two safety brackets.

CAUTION! Risk of injury - the inverter is heavy!

The inverter weighs approx. 70 kg.

 Never dismount the inverter on your own.

3� Extent of Repair and Replacement

SPUTNIK will maintain repair material and stock of each type of device during the warranty period only at its own reasonable discretion. In case repair materials for a certain type of inverter and/or an identical replacement device are not in stock anymore, the following applies:

 SPUTNIK is allowed to replace the defective inverter with a comparable device of the same or

superior per formance. The costs (time and material) for technical adjustments necessary for the installation of such comparable devices are covered by this warranty only up to a limited amount; any flat rate compensation owed by SPUTNIK for the replacement is deductible. Please do not hesitate to ask us about the currently applicable amount. The exchange and connection of peripheral devices due to possible non-compatibility with the replacement device or other necessary adjustments to the surrounding installations of the device (including power lines, ventilation and safety installations) are not covered by this warranty. However, SPUTNIK shall within the bounds of reasonability do its best to minimize the effort of such adaptation work.

 In case repair materials are not available with reasonable efforts anymore, SPU TNIK is allowed

to replace the inverter, subject to the conditions mentioned in the paragraph above.

4� Warranty Period in Case of Repair/Replacement

In case of repair or replacement of devices under this warranty, the repaired respectively replaced device will inherit the remaining warranty time of the original device.

5� Exclusion of Warranty

Especially in the following cases, this manufacturer’s warranty does not apply:

 Transport damage;

 Technical intrusions, modifications or repairs of the devices not authorized by SPUTNIK;

 Use of devices for purposes they are not intended for, incorrect or unreasonable manipulation,

incorrect or unreasonable installation;

 Failure to observe the manufacturer’s operating, installation and maintenance directions;

 Inadequate environmental conditions (e.g. insufficient ventilation of the device; humidity etc.);

 Superior force (e.g. lightning strike, overvoltage, floods, fire, etc.).

6� Handling of Warranty Cases

For the processing of warranty cases, use of SPT UNIK’s hotline is mandatory. The handling of warranty cases must take place in accordance with the instructions provided by the hotline. The hotline number for your country can be found on SPUTNIK’s homepage. Please hold the serial number, article description, a short description of the defect and the purchase receipt ready for transmission to the hotline.

Any repair action taken by the buyer or third parties without authorization by SPU TNIK will not be compensated.

In case these terms on the handling of warranty cases are not respected, SPUTNIK may refuse its warranty performances.

7� Suspension of Warranty

Sputnik reserves its right to suspend this manufacturer’s warranty temporarily or definitely in case a specific installation does not allow a correct functioning of the inverters (e.g. in case of one of the circumstances listed in cipher 5).

The suspension of the warranty can be lifted upon approval by SPUTNIK. Such approval must be issued by SPUTNIK in writing, confirming that the warranty has again become effective.

8� Warranty Extension

The warranty period can be extended through purchase of a warranty extension within the time limits mentioned hereafter. For certain types of devices, such warranty extensions can also be purchased only for a limited scope of warranty performances. The purchase of a warranty extension will be confirmed by SPUTNIK in form of a warranty certificate (including serial number of affected product). In case of replacement of a device, the serial number in such warranty certificate remains unchanged, without any influence on the validity of the warranty extension.

a) Time limits String inver ters: The extension of the basic warranty can be ordered within 60 months after purchase, but the latest within 72 months after dispatch of the device by SPUTNIK. Central Inverters: The extension of the basic warranty can be ordered within 3 months af ter purchase, but the latest within 12 months after dispatch by SPUTNIK.

b) Extent Full warranty extension – FULL (available for central inverters and string inverters): A full warranty extension includes all the warranty performances as described in the manufacturer’s basic warranty terms.

Limited warranty extension– LIMITED (available only for central inver ters): A limited warranty extension covers only the costs for the material required for the repair. The costs for travelling, labor and other expenses are not covered and will be invoiced on a time and expenses basis by SPUTNIK.

c) Effectiveness of Warranty Extension It is a mandatory requirement for the warranty extension to provide the completely filled out application form to SPUTNIK. The warranty extension becomes effective only after written confirmation and provision of the warranty cer tificate by SPUTNIK.

9� After Expiration of Warranty Period
