1. INTRODUCTION
In this application is kept backwards compatibility with ARFIFF07. The power generation application
is used to generate power to grid using the maximum power point tracker (MPPT) or manual DC
reference.
1.1 Grid Code Support Information
In this application is used general grid codes.
1.2 Compatibility issues in parameters between versions
NOTE! This application is not kept backwards compatible. See release notes and this chapter before
updating the application.
Update Note 1: When you update the application do not use NCDrive parameter download function.
Instead upload parameters from the unit and compare them to the old parameter file. The
application is constantly developed, and it includes changing parameter default values. If
parameters are directly downloaded to drive, improved default values will be lost.

2. GENERAL
The power generation application is an answer to growing renewable energy market. The inverters
need only DC voltage and the grid to start producing energy.
Picture 1. Basic solar system.
2.1 Basic features
The power generation application works with Multi master and Stand-alone configurations. It can be
used with thin film and polycrystal Solar panels. Multi master configured system is controlled by
external Touch panel.
Additional functions:
• Grid Code functionality.
• Possibility to send Power Limit also from Fieldbus
• Multi-Master functionality with daily master change.
• Maximum Power Point Tracking
• Possibility to set any parameter value through Fieldbus interface.
2.2 Stand Alone
There is only one inverter unit which is producing energy to the grid. This system is working alone and
there is no need to use any external control systems or backup systems.

Local contacts: http://drives.danfoss.com/danfoss-drives/local-contacts/
2.3 Multimaster ( 8 x inverter size)
The multi master functionality is used in bigger systems. There are two to eight inverter units which
are producing energy to the grid. This system has always the touch panel, which controls the system.
Inverters are equally loaded, because each time system is started, MPPT master is changed, which
will extend the lifetime of the inverters.
In the multi master system there is one inverter which is controlling other inverters behavior
and that inverter is called master inverter. Master inverter collects information of the DC bus and
makes decisions regarding what DC reference is used.
Other inverters are slave inverters and they follow DC reference coming from the master inverter.
Each of the inverters is responsible of its own behavior on the Grid side, i.e. complying with Grid Code
Standard.
Each unit is sending status information to operator panel and they can be read in touch panel.

made in the Keypad control menu (M3).
= I/O terminals are the selected control place; i.e. START/STOP commands or
reference values etc. are given through the I/O terminals.
= Control keypad is the selected control place; i.e. the Inverter can be started or
stopped, or its reference values etc. altered from the keypad.
= The inverter is controlled through a fieldbus.
= Run enable not active
= Unit is ready to start in the morning.
2.4.4
Status LEDs (green green red)
The status LEDs light up in connection with the READY, RUN and FAULT Inverter status
indicators.
(Ready) = Steady ON (no other LEDs): Start command has been given, all start criterions
have been fulfilled except that the drive has not detected high enough voltage
to start up.
Blinking at 2 Hz: All external start criterions have been fulfilled but no start
command has been given.
(Run) = Steady ON: The Inverter is running.
Blinking: Stop command has been given and the inverter is ramping power
down.
(Fault) = Blinks when unsafe operating conditions were encountered due to which the
Inverter was stopped (Fault Trip). Simultaneously, the Inverter status
indicator FAULT blinks on the display and the fault description can be seen
on the panel.

3. APPLICATION
3.1 Quick Application Commissioning Guide
The Power generation application has been design for easy and fast commissioning. The user only
needs to set the Basic parameters and check if the there are any I/O parameters to be changed.
The Basic parameters are meant to be set in numerical order. Then the option board parameters are
set correctly automatically and system is ready faster.
3.1.1
Commissioning Steps
Table 1. Application Commissioning Steps
Step #
Step
Description
1
If you are updating the application to newer
version, write down the following counter
values before updating:
V1.1.10 Total Energy kWh
V1.1.13 RunTime Total
V1.1.16 Grid Connections
V1.1.17 IntFanRunHours
V1.1.18 ExtFanRunHours
These values need to be written down so
that the counters can be reset to correct
values after application update.
2
After application update, write the
corresponding counter values to these
parameters:
P2.10.2 TotalEnergyPreset
P2.10.3 GridConnPreset
P2.10.4 TotalRunTimPrese
P2.10.5 IntFanRuntPresVa
P2.10.6 ExtFanRuntPresVa
Change parameter P2.10.1
This will set the counters to the values
before application update.
3
Define right grid settings
P2.1.1 Grid Nom Voltage
P2.1.2 Grid Nom Freq
P2.1.6 Transf inv. side
P2.1.7 Transf grid side
When grid settings are right drive voltage is
calculated correct.
4
Set parameters P2.1.7 and P2.1.8 in
numerical order.
By setting the parameters in numerical
order the necessary option board
parameters are set also automatically to
their correct/default values.
This speeds up the process especially in
Multimaster system commissioning.
5
If commissioning is done before large scale
power production is possible, set P2.1.9.1
DC Start Level parameter to a level where
the inverter will surely start when the sun is
up.
Otherwise no need to change anything else
in Basic Parameters
This parameter indicates the minimum DC
voltage needed for the drive to try start up. If
this is larger than the current DC level when
the drive is stopped (as it is during morning
or evening commissioning) the drive will not
start.
6
Set the I/O parameters in G2.3 as required.
Some fault or warning may have been
triggered due to wiring in customized
cabinet solutions.
7
Reset any possible faults.
Reset the possible wiring related faults /
warnings.
8
Set P2.9.
any one unit
This will start a SystemBus test procedure
that will blink the Ready, Run and Fault
LEDs in all of the drives in order, starting
from the inverter where the parameter was
set.
If the LEDs do not blink in all of the units,
check the optical cables, jumper settings in
16 • VACON® arfiff08 power generation
Local contacts: http://drives.danfoss.com/danfoss-drives/local-contacts/
OPT-D2 option boards and Basic parameters
in all of the drives.
9
Set P2.9.1.1 Simulation Mode to
and press start
in the Beijer panel
This activates the simulation mode where
drives use simulated DC voltage (P2.5.1.6)
and simulates power production which the
Beijer touch panel can see.
This test ensures that the system works as a
whole and the communication between the
inverters and Beijer touch panel is working
(in multimaster system) alright without
actually having DC or real output power.
You may need to lower the limit for starting
up the next follower in the Beijer
parameters to enable follower start ups.
10
When every drive in the system has ran,
press stop in the Beijer panel and set
P2.9
This disables the simulation mode and
enables the drive to run normally.
11
Give Start command.
If drive has not started but Ready LED is lit
and power production should be possible,
press Start button for 5 seconds.
If the DC is above the P2.1.9.1 DC Start Level
the drive will start. Pressing the Start button
for 5 seconds forces the drive to start
regardless of DC level.
12
Make sure parameter P2.1.9.6 DC Start
Level Max is set to appropriate value
compared to the specified open circuit
voltage of the panel field.
NOTE: during hot summer days, the actual
open circuit voltage can go as low as 90% of
the specified OC voltage, set the parameter
accordingly!
P2.1.9.6 DC Start Level Max is the absolute
maximum value that the addition of offset
after natural stops will not exceed. This is to
ensure that the start level never rises so
high that the drive will never start up.
13
In Multimaster system when power
production is ~75 % from system maximum,
use P2.2.2 DC Calibration to tweak the
output power of all of the drives to match
each other.
This is done to ensure that the small DC
voltage measurement errors between the
drives are not causing adverse effects on the
power production and the produced power
values are close to the same in the
Multimaster panel.

3.1.2
Multimaster PLC out of commission
If it happens that the multimaster control PLC is out of order, the drives are able to work using
master-follower operation mode where all of the drives are always working at the same time:
Step #
Step
Description
1
Set parameter P2.1.8 SB
This setting indicates for the unit #1 that it
needs to send the start command to the
other drives via SystemBus
2
Set P3.1 Control Source in the master to
Panel
This way the user can use the Panel to give
the Start command to the master unit and
the drive no longer listens to commands
from Fieldbus
3
Set P3.1 Control Source in all of the other
drives to SystemBus
This way the follower drives listen for the
Start command from SystemBus
4
Reset possible faults and give Start
command to the master unit.
If drives have not started but Ready LED is lit
in the Master unit and large scale power
production is possible, press Start button for
5 seconds.
The drives start up and start producing
power.
