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

MPP tracker & grid connection

The SM5TP2, SM6TP2 and SM7TP2 inverters have 2 independent MPP trackers which can be used to connect strings with different characteristics, such as orientation, size and module type. The SM4TP is tted with an MPP tracker. Each MPP tracker can be tted with one string as standard. The grid connection is a three-phase connection.

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 inverter has congurable functions for grid monitoring, limitation of output and reactive power control.

Interfaces / remote monitoring

For the purpose of monitoring the PV power plant remotely, the inverter can be connected directly to the Internet via Ethernet.

The inverter is tted with a multi-function relay which can be congured for various purposes (status signaling contact, control of self-consumption).

The inverter is tted with interfaces for remote-controlled shutdown and output control (active and reactive power control).

Extended functions

The inverter has functions for grid monitoring, limitation of output, reactive power control and control of self-consumption. These can be congured using MaxTalk2.

Ventilation

The inverter is air cooled. To a large extent, ventilation is passive via the vertical cooling ns on the back of the inverter. The fan on the left-hand side of the inverter (not available with SM4TP and SM5TP2), which is accessible from the outside, sucks in air which is also directed across the cooling ns. All inverters of the TP series are tted with an internal fan.

3.3 Safety installations

Surge protection

The inverter is tted with surge arresters (varistors) at its input and output. Each DC input (plus and minus connection) is tted with a surge arrester. On the AC side, the phases and the neutral conductor are individually secured with surge arresters. The surge arresters have a common gas discharge tube to ground. For further information on the surge arresters, see Section11.

When designing the PV power plant, it may be necessary to provide additional external lightning protection (overvoltage protection). The inverter has an interface for monitoring external lightning protection modules.

Fault current monitoring

The inverter has an integrated AC/DC-sensitive leakage current sensor. This recognizes leakage currents generated due to PV module capacities to ground (capacitive ground leakage current) or through insulation faults (for example by touching a pole of the PV generator or a phase). In the case of the permissible leakage current being exceeded, the inverter disconnects from the grid.

Functions for current and output limitation

The inverter limits the DC feed-in current, the output power and the output current.

Temperature limitation

480 189

[mm]

361

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.

13 Warranty

Sputnik Engineering AG (hereafter SPUTNIK ) guarantees full function and lack of defects of its technical devices for a warranty period as specified below for each type of device. Such warranty period can be extended by means of a warranty extension, subject to the conditions named below.

This manufacturer’s warranty exists next to the seller’s warranty (if any) as prescribed by law. As far as identical with regards to the content, the rights under this manufacturer’s warranty supersede any rights under the seller’s warranty. Please contact the seller with regard to any claims based on the seller’s warranty.

1. Warranty Period (Basic)

 Central inverters and accessories: 24 months from the date of purchase, but at maximum 30

months after dispatch of the device by SPUTNIK.

 String inverters: 60 months from the date of purchase, but at maximum 72 months after dis-

patch of the device by SPUTNIK.

If in individual cases SPUTNIK has agreed in writing to a dif ferent warranty period, such arrangement supersedes the above provisions.

2. Scope of Manufacturer’s Warrant y

In case of defect or malfunction of a device within the manufacturer’s warranty period, and upon fulfillment of the conditions for warranty claims named hereafter, the device will be repaired or replaced by SPUTNIK-service personnel within a reasonable time, in either case free of charge, unless this is impossible or disproportionate. SPUTNIK may decide at its own discretion whether a device will be repaired or replaced.

 Replacement: Exchange of device free of charge. SPUTNIK’s separate conditions for exchange

of devices apply: This warranty covers the free delivery of an equivalent replacement device. Further, your installer is entitled to claim a flat rate compensation for the replacement work from SPUTNIK. Please do not hesitate to ask us about the current amount of such flat rate compensation.

 Repair: Repair of device free of charge. This warranty covers costs for material, work and travel

by SPUTNIK personnel or by personnel authorized by SPUTNIK.

Please be aware that the per formances of SPUTNIK under this warranty are only free of charge in countries approved by SPUTNIK. Please contact your seller for details. A current list of approved countries can be found on our homepage. Repair and replacement outside of the approved countries are only possible after prior consultation of and approval by SPUTNIK. In such case, travel and shipment costs are borne by the customer.

Any further claims, especially claims for compensation of damages resulting directly or indirectly from the defect or claims for replacement of fur ther costs in connection with the installation and removal of devices or claims for loss of profits are not covered by this warranty.

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 effor t of such adaptation work.

 In case repair materials are not available with reasonable efforts anymore, SPUTNIK 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 SPU TNIK;

 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 SPTUNIK’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 SPUTNIK 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 warrant y 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 warrant y 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 af ter dispatch of the device by SPUTNIK. Central Inverters: The extension of the basic warrant y can be ordered within 3 months after 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 warrant y terms.

Limited warranty extension– LIMITED (available only for central inverters): 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 certificate by SPUTNIK.

9. After Expiration of Warranty Period

The costs for repair or replacement of devices after expiration of the warranty period are invoiced by SPUTNIK on a time and material basis. SPUTNIK will maintain repair and replacement capabilities beyond the warranty time only at its own discretion.

10. Applicable Law, Jurisdiction

Only Swiss Law applies. The exclusive place of jurisdiction lies in Biel/Bienne, Switzerland. (v 20 13/0 5)
