1 Product description

1.1 Proper use

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

Thanks to the HERIC

topology with FP switching, the AT Solar Inverter has a voltage curve which corresponds to that of a transformer device with an earthed negative terminal, and is generally also recognized for operation on thin-ﬁlm modules.

Solar modules which require earthing of the positive terminal cannot be operated with the AT Solar Inverter. If in doubt, always ask your module manufacturer about a release!

1.2 Function description

Conversion from direct into alternating current

The AT Solar Inverter converts the direct current produced by the solar generator into alternating current. The alternating current is then fed into the public power grid.

Operating and display elements

Various interfaces are available for system conﬁguration and monitoring:

· Operating ﬁeld (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 an analogue modem, ISDN modem or GSM/GPRS modem

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

· CAN bus interface for interconnecting several Solar Inverters

· S0 pulse output for controlling large displays

· Alarm relay for realising simple monitoring locally

· Interface for connecting an irradiation and temperature sensor

Data logging

The AT Solar Inverter is equipped with internal data logging for recording and saving system data:

· 5-minute mean values of voltages, currents, output, temperature and irradiation (if sensor is installed)

· 5-minute, daily, monthly and annual values of energy yield

· Memory for malfunction messages

Grid monitoring

The AT Solar Inverter assumes the task of grid monitoring for the protection of the device and persons. In case of abnormal grid conditions, feeding is immediately interrupted and the Solar Inverter disconnects from the grid by triggering the grid relay.

Design of Solar Inverter

The principle design of the AT Solar Inverters can be recognised from the block diagram. The most important characteristic of the inverter is the earthing of the solar generator, i.e. the negative terminal is directly connected to the neutral conductor on the grid.

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

inverter.

1.3 Integration in solar system

Design of solar generator

The technical data of the selected solar generator must be within the Solar Inverter‘s speciﬁcations (see Technical Data). Incorrect dimensioning can lead to reductions in the yield and to destruction of the device.

The design program Sunways Sundim may be helpful to you. Sunways Sundim is available on the included CD-ROM or at our homepage www.sunways.de.

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

· Watch the celestial alignment of the modules. A maximum yield is achieved in Central Europe with a module slope of 30° to the vertical and direction of the solar generator ﬁeld directly to the south.

· The output of the cells decreases as the module temperature increases. Install your solar generator with sufﬁcient ventilation from behind.

· Check your solar generator approx. every three years for soiling. This occurs especially on the lower edge of the modules and forms a veil that cannot be washed off even by heavy rain. Reduced yield can be prevented by cleaning with a wet cloth or a brush.

· Avoid switching off individual modules or solar cells of your system. This can lead to major decreases in yield.

Networking Solar Inverters via CAN bus

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

Device 1 Device 2 ...

1 1

1 Terminating resistor

The total length of the CAN bus depends on the selected bit rate. The following table shows the possible bit rates and the resulting bus lengths.

Bit rate Bus length 100 kbit/s 650 m 125 kbit/s 500 m 250 kbit/s 250 m 500 kbit/s 100 m

Solar Inverters of the PT series are delivered with a default setting of 125 kbit/s. The default setting for Solar Inverters of the NT and AT series is 500 kbit/s.

When Solar Inverters from different series are networked the bit rate in all units must be identical. The rate can be set via the Solar Inverter display or the Sunways Browser.

Setting the bit rate via the display menu: «Settings – Network – CAN Bus – Baud rate»

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 the bus length and the number of nodes:

Bus length / Number of nodes 32 64 100

100 m 0,25 mm

or AWG 18 0,75 mm2 or AWG 18 1,0 mm2 or AWG 16

Page 24

3 Installation

In cases where the values speciﬁed in the table cannot be adhered to, a CAN bridge for boosting the signal must be installed, through which the length of the CAN bus can be extended by up to 500 m. The requirement to install a CAN bridge is therefore determined by the bus length, the number of nodes and the cable cross-sections.

CAN-Bus

Network length / number of nodes / cable cross-section outside the table values – 1 or several CAN bridge(s)

INVERTER

CAN-BRIDGE

The CAN bridge is available from Sunways. For further information please contact the Technical Hotline.

The CAN bridge subdivides the bus into two physically independent segments. The maximum cable length of each segment is determined by the set bit rate. With a bit rate of 125 kbit/s two segments with a maximum length of 500 m each are possible. The total line length can therefore be up to 1 km under ideal conditions.

In systems with Solar Inverters from the PT series the CAN bridge can be integrated directly in the PT Solar Inverter and supplied via the 24 V DC power supply unit of the inverter. In systems with AT Solar Inverters and units from the new NT series (900 V) the CAN bridge can be integrated in the AC distribution. In this case an external 24 V DC supply is required (power consumption 1.5 W).

Networking Solar Inverters via RS485 interface

For joint monitoring of a solar system with Sunways Solar Inverters from the older NT generation (750 V or 850 V) you can use the RS485 interface integrated in the Solar Inverters. The system networked with the RS485 interface can be monitored with the Sunways Communicator.

· Use a twisted two-wire cable to network the Solar Inverters with each other.

· Mount the terminating resistor on the last Solar Inverter.

S0 interface

The S0 pulse output enables, for example, the connection of a large display (Sunways Display) for displaying the momentary output, the energy yields and the CO

reduction.

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. Go to the menu «Settings – Network – Interfaces».

· Please note that the maximum pulse rate may not be greater than 15 pulse/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.

Connection of temperature and irradiation sensor

The optional addition of an irradiation 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 device 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 alarm relay

The Solar Inverters are equipped with a potentialfree alarm relay as standard. The relay can be designed as a make-contact element or as a breakcontact element and is actuated for all malfunctions signalled by the device. This ensures a faster, more reliable indication of a possible fault in the PV system on site. For PV systems with several Solar Inverters, the individual relays can be switched in parallel and connected via a common indicator lamp.

The master also signals faults from other devices 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 device must be fused separately. The terminals are intended for a cable cross-section of 0.2 mm2 to 1.5 mm2. When dimensioning the cross-section, also take the current consumption of the connected signalling device into account.

6.1 General information

The basis for the system monitoring is the data logger integrated in the AT Solar Inverter. The Solar Inverters of the AT series are equipped with a broad range of monitoring options for your solar system:

· The Sunways Browser offers the display of instantaneous values, stored operating data and settings.

· With active alerting the master can send errors which have occurred in the solar system to a selected recipient by Email.

· With the Sunways Portal connection the AT Solar Inverter can send the operating data of your solar system to the Sunways Portal daily without additional hardware. This enables you to track your yields via the Internet.

One of the four possible connections between a PC and the Solar Inverter is possible for this purpose:

· Direct connection via an Ethernet cable or internal network

The Solar Inverter is unable to send e-mails via a direct connection. Portal connection and active alerting is therefore not possible.

· Connection via the Internet, e.g. connection of the Solar Inverter to a DSL connection

· Connection via a Sunways Modem

6.2 Integrated data logger

The integrated data logger of the AT Solar Inverter stores the operating data of your solar system. In addition to 5-minute mean values, energy yields are also stored as 5-minute, daily, weekly, monthly and annual values. Up to 200 status changes (warnings and errors with start and end) are also stored. Each data record contains the data and time. The data logger is designed as a circulating memory, i.e. the respective oldest data are overwritten with new data.

Operating data (5-min. mean values) Number Value

2000 DC current 2000 DC voltage 2000 AC current 2000 AC voltage 2000 AC output 2000 Device temperature 2000 Module irradiance (optional) 2000 Module temperature (optional)
