Safety of persons
Safety Warning! Incorrect operation and work performed incorrectly can cause serious injury & damage!
Only qualified staff are authorized to put your Conergy WR unit into operation and only within the scope of the respective technical regulations. Do not start operation or carry out maintenance works before you have read the chapter
„Safety Conditions“!
Housing unit Only qualified installers are authorized to open the connection area.
Opening the connection area is only permitted when it is not under voltage.
The separately insulation encased power stage shall only be opened when not under voltage and only by trained service staff.
Galvanic insulation
The design and function of the Conergy WR unit offer a maximum of safety, both during installation as well as in operation. A complete galvanic insulation between DC and AC side guarantees maximum safety.
The Conergy WR takes over the tasks of galvanic insulation and network monitoring. The passive and active measures for the protection of persons and equipment are understood by this.
Monitoring the electrical mains network
Whenever conditions in the electric mains network are inconsistent with standard conditions (for example mains switch-off, interruption), your
Conergy WR unit will immediately stop operating and interrupt the supply of power into the mains.
Your Conergy WR unit can monitor the situation in the mains in several ways, by
- monitoring voltage
- monitoring cycle frequency
- ENS (optional)
The ENS option is compulsory in only a few countries, and only for them the Conergy WR unit is available with this option. In any case however will the monitoring and safety systems integrated in the Conergy WR unit be available as standard equipment.
4
Monitoring the electric mains network
(continued)
The permanent ENS mains monitoring scheme is an additional link in its safety chain. One of the signs by which ENS identifies abnormal situations in the mains is a sudden increase of the impedance in the mains network.
Both the permanent mains monitoring by your Conergy WR unit directly as well as ENS make sure that in case of a mains blackout (due to being switched off by the utility company or due to a defect in the transmission line) it stops feeding power into the mains.
This scheme definitely prevents dangerous voltages at the AC lines and constitutes an essential contribution towards avoiding hazards for the maintenance staff.
Photovoltaic generator
Before connecting the solar modules, you must check whether the voltage parameters laid down in the manufacturer’s data correspond with reality.
When checking the voltage reading, please take into account that solar modules supply a higher no-load voltage when temperatures are low and insolation remains unchanged.
At an outside temperature of -10 degrees centigrade the no-load voltage of the solar modules must in no case exceed 500 V - or 530 V for the WR
5900E. The data sheet of the solar module will tell you the temperature factors applicable for ascertaining the theoretical no-load voltage at -10 degrees centigrade.
In case the solar modules exceed a no-load voltage of 500 V - or 530 V for the WR 5900E - the Conergy WR unit will be completely damaged and all warranty rights will cease to exist.
Mains connection
Only a licenced electricity installer is authorized to carry out the connection works to the public mains network.
DC plugs
AC plugs
Note!
If DC plugs are provided, they must never be disconnected from the sockets of the solar modules as long as the Conergy WR unit is feeding power into the mains. Before disconnecting the DC plug you must always disconnect in the fuse for the house distribution.
Note!
Disconnect AC plug connections only when the equipment is not under voltage, after having disconnected the fuse for the inhouse distribution panel.

General Introduction
How a photovoltaic system works
General information
The energy from worldwide insolation amounts to a total of about
1,540,000,000,000,000,000 kWh/year (1,540 Peta kWh/year). This is
15.000 times as much as the electricity consumption worldwide. We congratulate you on your decision to actively use world’s biggest energy pool. By the way, it was a scientist in the field of of physics, Alexandre-
Edmond Bequerel, who first discovered the photo-voltaic effect in 1839.
The name photo-voltaic comes from the driving force behind this technology, which is the ray of light. The ray of light consists of unimaginably tiny particles, the photons.
Your roof is your power generator
Let us simply start our explanation with a straight silicon solar cell. Remembering our physics class in school, we know that there are four electrons in the outside electron shell of a silicon atom arranged around its atomic nucleus, they are the so-called peripheral valency electrons. The sunlight’s photons enter the solar cells and concentrate energy in the valency electrons. The electron eventually separates from the silicon atom and leaves behind it an atom with a positive charge.
So that the free electrons will flow in one direction and thus generate electricity, the poles on the front and back side of the cell must be different from each other.
The silicon atoms of the front must be packed with a slight quantity of phosphor atoms which contain an additional valency electron. On the back of the cell, atoms of boron having only three valency electrons are added to the silicon atoms.
The result is an imbalance which makes the electrons flow, and this is how electric power is generated.
Many such solar cells united together and packed behind glass form one of your solar modules.
7
Your roof is your power generator
(continued)

Power output and voltage are increased by combining a number of solar cells. If solar modules are connected in series like on a string, both the output potential as well as the voltage will increase.
+
-
Mod. 2
Mod. n mod. 1 mod. 2 mod. n
In a parallel connection of several such strings the potential output and the modular electric power will increase, while the voltage will remain unchanged. The total of all solar modules connected parallel and in series is called solar generator.
-
Electricity is converted under the roof
The direct current generated in the solar modules can be fed into the public mains network or put to home use after having been transformed in an inverter.
This is the basic purpose of your Conergy WR unit.

The Conergy WR unit in the Photovoltaic System
General information
Your Conergy WR unit is the latest generation of solar inverters. It is the highly complex link between solar modules and the public electricity mains network.
As such it is in charge of a number of highly qualified tasks.
Transforming
DC into AC electricity
The Conergy WR unit transforms the direct current generated by the solar modules into alternating current. This alternating current is fed into your home system or into the public mains synchronically with the voltage which is used there. The Conergy WR has been designed exclusively for use in mains connected photovoltaic schemes. It cannot generate electric power independent from the public mains network.
Fully automatic operation management
The operation of the Conergy WR unit is fully automatic. Starting with sunrise, as soon as the solar modules generate enough power, the automatic control unit starts monitoring voltage and frequency. As soon as there is a sufficient level of insolation, your solar inverter starts supplying and feeding power. A few Watts of solar power output are sufficient to achieve this, depending on which version the unit is!
The operation of the Conergy WR unit ensures that at any time the maximum possible power output is drawn from the solar modules.
This function is called MPPT (Maximum Power Point Tracking). It operates with extremely high precision. As dusk starts there is no more sufficient energy available to feed power into the mains, the Conergy WR unit shuts the mains connection completely and stops operating. All settings and data recorded are of course saved.
Voltage transformation and galvanic insulation
The Conergy WR has been designed for use with solar modules of a wide range of input voltages. This allows the use of the greatest variety of types of solar modules. Important notice: the parameters indicated for maximum
DC voltage (total voltage of the solar cells connected) must at no time be exceeded!
By its design and operation, the Conergy WR offers a maximum of safety during installation as well as in operation.
9
Voltage transformation and galvanic insulation
(continued)
The Conergy WR is equipped with an HF-transformer (HF = high frequency) which assures a galvanic insulation between the DC side and the mains. In addition, the HF principle results in a drastic reduction of the transformer’s size, which means that it requires less space and has considerably less weight. In spite of its full galvanic insulation, the Conergy WR unit achieves a high degree of efficiency, due to its innovative circuit schemes.
Monitoring the mains network
The Conergy WR unit is in charge of monitoring the mains network. This responsibility comprises all measures necessary for the protection of persons and machines in case of a power blackout.
The Conergy WR unit is programmed to stop operation immediately and stop supplying power whenever conditions in the mains network deviate from standard (for example when power is switched off or in case of any other kind of interruption).
There are several ways how the Conergy WR unit can identify a mainscutoff, it can do so for example by monitoring:
- voltage
- frequency
- resistance (only Conergy WR with ENS)
For this purpose it is important that the specific monitoring procedures applicable for the respective countries are carried out directly by the Conergy WR unit without the use of additional electronic monitoring devices.
This will result in a substantial reduction of the installation work and cost.
Display function and data communication
The complex technical systems of innovative solar inverters make it necessary to design the display which is the interface with the user very carefully. It is an unwavering design aiming at ease of operation and permanent availability of the system’s data.
The Conergy WR unit is equipped with a basic recording function for monitoring minimum and maximum data on a daily and a cumulative basis directly from the display. There is also an option to allow the reading of the following weather data on the display:
- two different temperature readings (for example temperature at the solar modules as well as the outside temperature in the shade)
- insolation
In additition to the functions installed in the Conergy WR unit, a wide choice of elements offered for data communication allows for many possibilities of recording and visualising data. The respective components required to upgrade the system are easy to install using the IG DatCom operating instructions. The installation of system upgrades, such as Dat-
Com components, allows for possible remote system monitoring via modem, text messages to mobile phones in the event of faults, data visualisation and data comparison on the PC.
10
Your advantage
With each additional task, as described above and controlled directly by the inverter, installation becomes easier and less costly because no additional peripheral equipment will be required. Based on our experience and the use of the most innovative technologies, the Conergy WR unit is able to manage all these tasks simultaneously.
In addition, the Conergy WR unit complies with a whole number of requirements established for the safety of people and other household appliances, as well for its own safety.
Some of these requirements are:
- ability to monitor the mains network
- the quality of the electricity supplied
- detection of outside disturbance and interference (for example mobile telephones).
Annexed you will find the respective certificates.

Product description
The Conergy WR Unit
How it functions
The Conergy WR unit is designed for fully automatic operation. Basically no personal control is necessary for feeding the power it generates into the mains network.
The Conergy WR unit starts operating automatically as soon as the solar modules produce sufficient power output after sunrise. From this point onwards, you will also receive system information from the Conergy WR graphic display.
During its operation the Conergy WR unit maintains the voltage of the solar modules at any time within the range of optimal power withdrawal.
- the optimal voltage for any particular status of operation of the solar modules is called MPP voltage (MPP = maximum power point)
- exactly maintaining the MPP voltage guarantees an optimal level of the efficiency factor of your solar modules at any time (MPP-tracking).
As soon as dusk begins there is no more sufficient energy available to feed into the mains network, the Conergy WR unit fully shuts off the mains connection.
- during the night the Conergy WR unit does not draw any energy from the public mains
- the data and parameters set remain available
- it is also possible to shut the unit off manually
Startup phase
After having switched on automatically, the Conergy WR unit goes through a self-test, and after that through a test of the public mains network.
This test takes between only few seconds up to several minutes, depending on the regulations in your country. During startup the LED illumination is yellow.
(1) Segment test
- all display elements light up for about one second
(2) TEST
- self test of important components of the Conergy WR unit
- The Conergy WR unit goes through a master check list for a period of only a few seconds

(continued) module voltage ... voltage in the solar modules at the moment of data display
The voltage indicated during power supply into mains is equal to the socalled MPP voltage (MPP = maximum power point). The Conergy WR unit keeps the module voltage always within the maximum possible power output withdrawal from the solar modules. This always guarantees an optimum efficiency performance of your photovoltaic generator..
module power ... power supplied by solar modules at the moment of data display (Ampere)
The Conergy WR unit keeps the module voltage always within the range of the maximum possible power withdrawal from the solar modules. This results in the optimum for the module electricity.
* module temperature ... temperature at solar modules
(degrees centigrade; can also be set for degrees Fahrenheit; temperature sensor No.1; sensor card optional) isolation resistance of photovoltaic generator (MOhm)
Isolation resistance is the resistance between the positive pole or the minus pole of the photovoltaic generator and the grounding potential.
Whenever an isolation resistance higher than 500 kOhm is shown, the photovoltaic generator is sufficiently insulated.
Warning!
An isolation resistance < 500 kOhm can be caused by an insufficiently insulated DC cable or by defective solar modules. In case of an insufficient isolation resistance you must in any case contact your Conergy service partner.
Important!
Only an isolation resistance of less than 500 kOhm indicates that there is an error. Whenever a higher insulation resistance is shown it is not to be interpreted as an error.
Whenever there is an isolation resistance of less than 10 MOhm, the display differentiates between the negative potential and the earthing
(minus sign „-“) and the positive potential and the earthing (plus sign „+“)

Additional information
Upgrading the system
The Conergy WR unit is prepared for a whole series of system upgrades.
The following system upgrades (compatible with IG Dat Com) are available for example:
- for communicating between Conergy WR and outside system extensions, for example with other Conergy WR units
- Data logger (for recording and managing data from your photovoltaic system by PC) including datalogger and modem connection
- Various large displays
- Actuators / Relays / Alarm
- Sensors
The system upgrades are offered in slot-in boards, similar to those on your personal computer.
For increased flexibility, all upgradings are also available in a version with external housing
LocalNet is a data network which allows linking more than one Conergy
WR unit with the system upgrade elements.
LocalNet is a bus system. One single cable is sufficient to allow communication between one or several Conergy WR units with all system upgrade elements. This reduces the cable requirement to a minimum.
39
Upgrading the system
(continued)
Please take further details from the chapter „LocalNet“ of the installation and service manual.
Forced ventilation
The Conergy WR unit is equipped with a temperature and rotation controlled air circulator which provides for the following features:
- smaller heat sinks - more compact housing
- components are better cooled - efficiency increases / longer life
- least possible energy consumption / noise level, due to rotation control and ball bearing support
- should there not be sufficient heat discharge in spite of maximum rotation of the ventilator (for example no adequate heat transfer away from the control panels) the power will be derated for auto-protection of the
Conergy WR unit.
- derating the power reduces the output of the Conergy WR unit for a short period sufficient to ensure that the temperature will not exceed the admissible parameter.
- your Conergy WR unit will remain ready for operation as long as possible without any interruption.
- Even if the Conergy WR is frequently used at full load the fan can be expected to last approx. 20 years.

Installation
Choosing the location general
Make the best possible use of your Conergy WR unit by additionally observing the following conditions:
- mains impedance should not be unnecessarily increased by a too narrow AC conductor cable cross section between the Conergy WR unit and the in-house distribution panel. The AC conductor cable resistance between the Conergy WR unit and the house distribution panel must not exceed 0,5 Ohm.
- install it only on a solid vertical wall
- The ambient temperature should not be under minus 20 degrees or over 50 degrees centigrade.
- No objects must be located within a distance of 15 cm around the air vents on both sides of the Conergy WR unit
- Keep a lateral distance of 20 cm between individual Conergy WR units.
- The air flow direction within the inverter is from left to right (cold air intake left, hot air exit right).
- When installing the Conergy WR unit in a switch panel cabinet (or similar closed sections) it is necessary to make sure that the hot air which develops will be discharged by forced ventilation.
Choosing the location
The Conergy WR unit can only be installed inside buildings or on outside locations provided that they are protected from rain or snow.
- During certain operation phases the Conergy WR unit may develop a slight noise level, for this reason it should not be installed in the immediate vicinity of living areas
- the Conergy WR unit is not to be set up in areas where there is heavy dust development
- the Conergy WR unit is not to be set up in areas where there is heavy incidence of conducting dust particles (for example iron filings)
43
Choosing the location
(continued)
- the Conergy WR unit is to be installed at a height which keeps the display slightly below the position of your eyes in order to secure best possible readability of the display.
- The distance between the top edge of the Conergy WR and the ceiling should be approx. 30 cm.
Fixing the wall mounting frame
Hazard due to supply voltage and DC-voltage from the solar modules. Only licensed electricity installers are authorized to open the connection area.

Important! Dowels and screws are not included as there are too many different types on the market to suit different wall surfaces.
- fix wall mounting frame (1) with suitable screws (2) and dowels
(3) on to a solid base.
- Open the connection area of the
Conergy WR unit (chapter „Opening the Housing“)
Caution!
There is a danger of the machine toppling over. Hang the
Conergy WR unit into the wall mounting frame and secure it with screw (4) in the connection area.
- install AC and DC cable as described in chapter „Connection“.
- close connection area and mount cover by means of tightening screw.
44
Fixing the wall mounting frame
(continued)
The housing is designed for a cable channel of up to 50 mm height which can be located directly below the connection area, without
- cables visible below the Conergy WR unit
- impairing access to the connection area and the slot- in board area
Important!
Should a cable channel be located below the Conergy WR unit, the following must be observed:
- lower edge of Conergy WR unit will be located exactly 26 mm beneath the wall mounting frame
26 mm

Connection
Connection to the Solar Modules and to the Public
Mains
Solar modules The following points are important for the most economic use of the Conergy WR unit when choosing suitable solar modules:
- the no-load voltage increases when temperature decreases with insolation remaining unchanged. Therefore the no-load voltage must not exceed 500 V - or 530 V for the WR 5900E.
Whenever the no-load voltage of the solar modules exceeds 500 V - or
530 V for the WR 5900E - the Conergy WR unit will be destroyed, and all warranty rights will become null and void.
- More exact data for dimensioning the solar modules for the location chosen can be obtained using calculation schemes.

As your Conergy WR unit need be connected to only one phase of the mains network, in can be installed in almost any part of the house.
Warning!
In order to ensure the best possible functioning of the mains monitoring system, it is important to make sure that there is a minimum of resistance in the feeding lines to the connection point.
The AC conductor resistance between the Conergy WR unit and the house distribution panel must not exceed 0,5 Ohm.
Warning!
Hazard due to supply voltage and DC-voltage from the solar modules. Only licenced electricity installers are authorized to open the connection area and only provided that it is not under voltage.
Schemes with more than one inverter
For larger photovoltaic schemes it is possible to connect several Conergy
WR units in parallel without any problems.
In order to secure a symmetric feed-in of the power supply, the Conergy
WR units should be connected evenly to all 3 phases.
If you have any doubt you should approach your specialized dealer whenever there are technical problems.

For your personal configuration please consult the chapter „Operating
Scheme“, section „Setup Menu“ of your operating instructions.
For settings to connect more than one inverter at the LocalNet (such as numbering of the bus partners connected/system upgrading) please consult the chapter LocalNet
LocalNet
System upgrading / slot-in board system
Your Conergy WR is pre-set for quite a number of system upgrades. The following system upgrades (compatible with IG Dat Com) are available or coming up soon:
- data recorder (for recording and managing photovoltaic system data on your PC) including modem connection
- Various large displays
- Actuators / Relays / Alarm
- Sensors
The system upgrades are available in slot-in boards as you have them for your personal computer. To increase flexibility, several system upgrades can be obtained also with external housing.
The LocalNet is a data network, which allows the connection of one or more Conergy WRs to the system upgrades.
The Conergy WR is prepared for four plug in cards within the housing.
Data recorder The data recorder is the core of the LocalNet. It coordinates data transmission and ensures quick and safe distribution also of larger data volumes.
COM Card In order to tie in the Conergy WR unit with the LocalNet, the following system upgrading is required (slot-in board)
- COM card ......................... for exchanging data between your Conergy
WR unit and the LocalNet, including the respective upgradings
Note!
Should the data recorder collect only data of one single photovoltaic converter, a COM card is nevertheless required. In this case the COM card is needed to couple the internal network of your Conergy WR with the LocalNet interface of the data recorder.
52
Insert slot-in boards, Conergy WR
For inserting the system upgrade slot-in boards proceed as follows:
Warning!
Hazard due to supply voltage and DC-voltage from the solar modules. Only licensed electricity installers are authorized to open the connection area and only on condition that is not under voltage.
(1)
(2)
(3)
(4) insert ENS card only in this slot
- open connection area - see chapter „Open the Housing“
- slide display towards the left side (1) and remove it from the front (2)
- loosen fastening screw and remove board slot cover
Note!
In dealing with slot-in boards please observe the general
ESD regulations.
- insert board (3) in any one of the slots
- tighten board (3) with fastening screw (4)
For versions for countries where the ENS card is a standard requirement, the unit will not operate without this card. Legal regulations require a safety system which does not allow operation of the Conergy WR without installation of ENS.
- power supply feeding operation can be resumed as soon as the ENS card is placed back in the slot (slot on the left outside, see illustration)
53
Configuration LocalNet automatically identifies different system upgrades (data recorder, sensor card, ...)
To differentiate between several identical system upgradings, the respective units must have an individual number.
To define each Conergy WR clearly in the LocalNet, an individual number must also be allocated to each Conergy WR.
For the respective procedure, please consult the chapter „Setup Menu“ in your operating instructions.
Example
Example: Recording and archiving inverter and sensor data by means of a datalogger card and sensor box.
The cards communicate within the Conergy WR unit via its internal network. External communication (LocalNet) is effected via the COM cards.
Each COM card has two RS-485 interfaces for entry and exit. Connection is effected with RJ45 plugs.
The first Conergy WR unit with COM card can be located at a distance of up to 1000 m from the last Conergy WR unit with COM card.

Status diagnosis and repair
Service-Codes Displayed
Service display
Your Conergy WR unit is equipped with a self diagnostic system which automatically identifies a large number of possible defects by itself and displays them on the screen. It is thus possible to quickly ascertain defects in the Conergy WR unit, in the photovoltaic system as well as installation and operation errors.
Whenever the self diagnostic system has identified a particular defect, the respective service code is displayed on the screen.
Note! Display of a service code for a short time may be a result of the control procedure of your Conergy WR unit. If subsequently it continues to operate normally, there has not been a case of an error.
General service codes
As long as the no load voltage of the solar modules is not sufficient, the screen displays the information „DC
LOW
“.
As soon as the no-load voltage exceeds 150 V, the Conergy WR unit starts synchronizing the network (display shows „SYNC
AC
“).
55
General service codes
(continued)
As long as the power output at the solar modules is insufficient, the display shows the message „POWER
LOW
“.
Complete failure
After a short time of waiting the Conergy WR resumes network synchronization (message: „SYNC
AC
“).
Should the display remain dark for a longer period of time after sunrise you must check the no-load voltage of the solar modules.
Should the no-load voltage of the modules (at the connecting points of the
Conergy WR unit) not reach 160 V, it is possibly the case of a defect in the remaining part of the photovoltaic system.
If the no-load voltage of the solar modules (at the connection points of the
Conergy WR unit) amounts to more than 160 V, there may be a basic defect in the Conergy WR unit. In this case you must consult a trained service technician.
Conergy WR with several power stage sets
A special status diagnostic is run if an error occurs in a Conergy WR with several power stage sets. The examples shown below illustrate the trouble-shooting process.
