1 Product Description

· Alarm relay for realising simple monitoring locally

1.1 Proper use

The Sunways Solar Inverter PT 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 fixed earthing of the positive or negative terminal cannot be operated with the PT Solar Inverter. If in doubt, always ask your module manufacturer whether the modules can be used without earth reference.

· Interface for connecting a irradiation and temperature sensor

Data logging

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

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

· 5-minute, daily, monthly and annual energy yield values 1.2 Function description

Conversion from direct into alternating current

The PT 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 as a three-phase current.

Operating and display elements

· Various interfaces are available for system configuration and monitoring:

· Operator 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

· Memory for malfunction messages

Grid monitoring

The PT 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.

Solar Inverter configuration

The basic configuration of the PT Solar Inverter 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-phase feed and passive grid monitoring.

Interfaces

· Bus interface for connecting a Sunways Modem, analog 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

1.3 Integration in solar system

Solar generator configuration

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 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 www.sunways.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 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 shading of individual modules or solar cells in your system. This can lead to major reductions in yield.

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».

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 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.

· Please note that the maximum pulse rate may not exceed 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.

Connecting the 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.

1 Indicator lamp, red

2 Indicator lamp, green

The Solar Inverter is supplied by the feed-in phase from the AC grid. If the feed-in phase fails the alarm relay cannot switch, even in the event of a fault.

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 mm 2 to 1.5 mm 2 . When dimensioning the cross-section, also take the current consumption of the connected signalling device into account.

6 System monitoring

6.1 General

The basis for the system monitoring is the data logger integrated in the PT Solar Inverter. The Solar

Inverters of the PT 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 the master can send errors which have occurred in the solar system to a selected recipient by e-mail.

· Via the Sunways Portal connection the PT Solar

Inverter can send the operating data of your solar system to the Sunways Portal on a daily basis without additional hardware. This enables you to track your yields via the Internet.

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

· Direct connection via an Ethernet cable or internal network

6.2 Integrated data logger

The data logger integrated in the PT 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. In addition up to 100 error/warning messages can be stored. Each data record contains the data and time. The data logger is designed as a circular buffer, i.e. the oldest data are overwritten with new data.
