PT 30k to PT 33k 7

1 Product description

1.1 Intended use

The Solar Inverter from PT series is the link between your solar generator and
the public power grid. The energy from the connected solar generator is con­verted to grid-compliant AC current and fed into the grid.

Solar modules which require earthing of the negative or positive terminal can­not be operated with the Solar Inverter PT 30k to PT 33k. If in doubt, always ask
your module manufacturer about a release!

1.2 Functional description

Conversion from direct to al­ternating current

The Solar Inverter PT 30k to PT 33k converts the direct current produced by the
solar generator into alternating current. The alternating current is then fed into
the public power grid as a three-phase current.

Operating and display ele­ments

Various interfaces are available for system configuration and monitoring:

 Control panel (LCD display and keyboard) for displaying operating and status

values or for inputting system parameters

 Operating LED

 Integrated web server for display and configuration via a web browser

Interfaces  Bus interface for connecting a Sunways modem, an analog modem, an ISDN

modem or a GSM/GPRS modem

 Ethernet interface for connecting a PC or for integration in existing networks

 RS485 interface for communication with external data loggers

 CAN bus interface for interconnecting several Solar Inverter

 S0 pulse output for controlling large displays

 Activation of large display in web browser

 Alarm relay for realising simple monitoring locally

 Interface for connecting an irradiance and temperature sensor

Data logging The Solar Inverter PT 30k to PT 33k offers internal data logging for recording

and saving system data:

 5-minute mean values of voltages, currents, output, temperature and irradi-

ance (if sensor is installed)

 5-minute, daily, monthly and annual energy yield values

 Memory for malfunction messages

Grid monitoring The Solar Inverter PT 30k to PT 33k assumes the task of grid monitoring for the

protection of the unit and persons. In case of abnormal grid conditions, feeding
is immediately interrupted and the inverter disconnects from the grid by trigge­ring the grid relay.

Product description

8 PT 30k to PT 33k

Design PT 30k to PT 33k The basic configuration is shown in the block diagram.

The solar generator voltage connected to the inverter input is initially adapted
by the DC actuator and then converted to alternating current by the high-effici­ency HERIC

®

inverter. The AC connection is made with 5 wires due to the 3-pha-

se feed and passive grid monitoring.

1.3 Integration into solar system

Solar generator configuration The technical data of the selected solar generator must match the PT 30k to PT

33k specification (see Technical Data). Incorrect dimensioning can lead to reduc­tions in the yield and to destruction of the unit.

The Sundim design program from Sunways can be used for this purpose. Sun­ways Sundim can be found on the enclosed CD-ROM or on our website at http:/
/www.sunways.eu/de/.

Be sure to take the following points into account before planning your system:

 Watch the celestial alignment of the modules. In Central Europe a maximum

yield is achieved with a module tilt of 30 to the horizontal and direct south
orientation of the solar generator
field.

 The cell output decreases as the module temperature increases. Install your

solar generator with sufficient ventilation at the rear.

 Check your solar generator approx. every three years for soiling. This occurs

especially on the lower edge of the modules and forms a haze that cannot
be washed off even by heavy rain. Yield reduction can be prevented by
cleaning the modules with a wet cloth or a brush.

 Avoid shading of individual modules or solar cells in your system. This can

lead to major reductions in yield.

 Please note the maintenance intervals of the inverter. See servicing schedule

on enclosed product CD.

 The Solar Inverter must be installed upright to enable adequate free convec-

tion.

 Solar Inverter may not be stacked in order to prevent excessive warming.

 If several PT Solar Inverter are operated in an enclosed space, adequate fresh

air supply must be ensured. Larger systems should be configured in collabo­ration with Sunways at the design stage.

 The ambient temperature must be between -20 C and +40 C. At ambient

temperatures above 40C, the Solar Inverter automatically regulates its out­put downwards.

 The IP 42 and IP 54 variants should not be exposed to direct sunlight to pro-

tect them from unnecessary external warming. The outdoor version is pro­tected by a sun shade for operation in direct sunlight.

Installation (IP 42, IP 54 vari­ants)

For Solar Inverter installation, proceed as follows:

1. The Solar Inverter is attached to the pallet with retaining claws. Remove the
retaining claws.

2. Use a trolley for transporting the unit to the installation site.

3. Use the retaining claws to secure the Solar Inverter on the installation sur­face.

Do not subject inverters to extreme shocks, otherwise the internal shock indi­cator will be activated (>25 g acceleration) and the unit guarantee thus rende­red void.

Networking of Solar Inverter
via CAN bus

The Solar Inverter from the NT (900 V), AT and PT series can be networked via
the CAN bus interface. Use the included Ethernet cable to network the Solar In­verter with each other. Connect a terminating resistor at the first and last Solar
Inverter in the series. The pluggable terminating resistors are contained in the
delivery scope.

1 Terminating resistor connector

NOTE

Solar Inverter from the PT series are provided with a default setting of 125 kbit/
s as standard. In contrast, Solar Inverter in the AT and NT series have a default
setting of 500 kbit/s.
When networking units from different series, the bit rate must be configured
identically in all units. This adjustment can be made either on the display of the
Solar Inverter or in the Sunways browser.

Up to 99 NT, PT and AT series units can be networked via a CAN bus. The fol­lowing table shows the recommended cable cross-sections depending on bus
length and number of nodes:

If the values in the table cannot be maintained, the signal must be strengthened
with the installation of a CAN bridge, with which the length of the CAN bus can
be extended up to 500 m. Bus length, number of nodes and the cable cross-sec­tion thus influence the way in which a CAN bridge is used.

You can purchase the CAN bridge from Sunways - please contact the Technical
Hotline.

The CAN bridge divides the bus into two physically independent segments. This
maximum cable length of each segment is determined by the bit rate set. There­fore with a bit rate of 125 kbit/s, it is possible to have two segments with a ma­ximum length of 500 m respectively. The total cable length can thus stretch up
to 1 km in ideal cases.

To do this, if a system has a unit from the PT series, then the CAN bridge can be
directly integrated into the PT Solar Inverter over which a 24 V DC power supply
unit can be supplied with electricity. If a system has single-phase units of the
Sunways, the CAN bridge can be integrated into the AC power distribution. In
this instance, an external 24 V DC supply is necessary (power consumption 1.5
W).

You can use the S0 interface on the master if you want to transmit the entire
line yields as a sum to a large display.

The S0 interface is adjusted via the display on the inverter. Open the menu "Set­tings - Networking - Interfaces".

NOTE

 Please note that the maximum pulse rate may not be greater than 15 pulses/

sec. Calculate the pulse rate depending on the size of the solar system using
the following formula:

Pulse rate [pulses/kWh] = 50,000 / system size [kWp]

 The pulse rate must be set on your Solar Inverter and on the large display.

Temperature and irradiance
sensor

The optional addition of an irradiance sensor (model Si-01TC-K from Ingenieur­büro Mencke & Tegtmeyer) with an integrated PT-100 temperature sensor for
temperature measurement enables the acquisition of irradiation data and the
corresponding module temperature and storage in the internal data memory as
a 5-minute mean value. This additional measuring unit helps analyse the system
output. Based on the values, any errors on the PV generator, e.g. shading or fai­lure of solar cells, can be detected.

The sensor is activated via the display. In the menu Settings - Network - Inter­faces, you can select the sensor type in the Irrad. and Temp. field.

Connecting the alarm relay The Solar Inverter is equipped with a potential-free alarm relay as standard. The

relay is can be designed as a make-contact element or as a break-contact ele­ment and is actuated for all malfunctions signalled by the device. This ensures
fast, reliable indication of a possible fault in the PV system on site. For PV sys­tems with several units, the individual relays can be switched in parallel and con­nected via a common indicator lamp.

The master also signals faults from other units in the CAN network via the alarm
relay. It is therefore sufficient for simple alerting to connect the alarm relay of
the master.

CAUTION

The alarm relay is designed for 230 V / 2 A. Higher outputs/voltages can result
in the relay being destroyed. The connected signalling unit must be fused sepa­rately. The terminals are intended for a cable cross-section of 0.2 mm

2

to 1.5
mm2. When dimensioning the cross-section, also take the current consumption
of the connected signalling unit into account.

NOTE
Configuration of grid security management

The inverter has grid management functions in accordance with the following
guidelines:

 Technical directive "Power generating facilities using medium-voltage grids"

from the German Energy and Water Association (BDEW).

 VDE code of practice "Power generation facilities using low-voltage grids"

These functions can be configured via the Sunways browser on your computer.
The inverter must be connected to the network in order to configure these func­tions. A device-specific password is required for access to the grid security ma­nagement configuration pages. This can be obtained on request from the
technical hotline. To do this you must quote the serial number of the inverter
which has been configured as the master.

6.2 System monitoring

General information The basis for the system monitoring is the data logger integrated in the Solar

Inverter PT series. The Solar Inverter of the PT series series offer a wide range of
monitoring options for your solar system:

 The Sunways browser can display instantaneous values, stored operating

data and settings.

 With active alerting, information about faults in the solar system can be sent

to a selected recipient via e-mail.

 Via the Sunways portal connection the PT series Solar Inverter can send the

operating data of your solar system to the Sunways portal on a daily basis wi­thout additional hardware. In this way, you can monitor your yields via the
Internet from wherever you are.

Three networking options are available for access to the system monitoring
function:
