Service menu
Contents of this chapter
This chapter describes the Service menu, when to use it and how to access it.
Service menu overview
In the basic use of the inverter you do not need the Service menu. However, some of the
inverter features are accessible only from the Service menu. For example, you can make
custom settings for countries that are not defined in the inverter software or adjust the
inverter’s operating parameters to better meet the local requirements.
Accessing Service menu
1. From the screen saver display or output view screen, simultaneously push the left soft
key, right soft key and Help button. If you push one button before the others, you need
to try again.

10 Service menu
2. Enter the PIN 6988. Use the up, left and right arrows to enter the digits. Press the right
soft key to save.
3. Scroll down the menu and enter the Service submenu. The heading Parameters is
now shown on the list.

Service menu 11
Exiting Service menu
If you do not press any buttons on the inverter for a preset period of time, the screen saver
turns on and you exit the Service menu. For instructions on changing the screen saver
delay, see chapter Setting screen saver delay on page 11.
To exit the Service menu before the preset period expires, for example, to prevent anyone
from altering parameters in your absence:
1. From the screen saver display or output view screen, simultaneously push the left soft
key, right soft key and help button.
2. Push Cancel without entering the PIN.
Setting screen saver delay
If you do not press any buttons on the inverter for a preset period of time, the screen saver
turns on and you exit the Service menu. To return to the Service menu, see Accessing
Service menu on page 9. If an assistant is active or waiting for a response from the user,
the screen saver does not turn on.
Before using the Service menu, increase the preset screen saver delay so you do not
need to repeatedly access the menu. This is useful especially when the delay is short. You
can change the screen saver delay from the Screen menu and set the value from 30
seconds to 10 minutes. Remember to reset the delay back to the original value after you
have finished working with the Service menu.
Parameters you are allowed to change
It is possible to change parameters and their values through the Service menu almost
without any restrictions. But you are allowed to change only the parameters and their
values such that they comply with relevant local requirements and regulations as set by
the local authority.

Control and monitoring interfaces
In basic setup the operation of PRO-33.0-TL inverter does not require any user actions.
Once the inverter is commissioned, automatic functions start and stop the inverter based
on measurements.
In some cases the inverter requires monitoring and additional control. You can control and
monitor the inverter locally from the control unit and remotely through the fieldbus
interface.
The control unit operation and menu structure are described in the PRO-33.0-TL Product
manual (3AUA0000123261 [English]).
Operational description
PRO-33.0.-TL inverter operation follows the state machine described below.
•MPPT is the normal operational state during power generation.
•If a power limitation is active, the inverter is in the Limited state while the inverter
produces energy to the grid.
•When the DC power level from panels is low, the inverter is in the Sleep or Standby
state depending on the night mode settings (parameter 189.07 Night mode).
•Connection tests is a state the inverter goes through every time it connects to the grid
and performs tests for DC voltage and internal protection devices.
•If a fault occurs, the inverter moves to the Standby state and waits for a reset
command (manual or autoreset).
The conditions for state transitions are as follows:
1VDC>~300V

580 and 950 volts when the AC voltage is nominal 400 VAC.
•MPPT range @ PAC, rated = maximum power available with tracking, no derating
•MPPT range = maximum power tracking range, power may be derated.
•Start range = Input voltage range where inverter may start
Start range
The inverter starting range is between 610 V and 1000 V. The minimum startup voltage
depends linearly on AC voltage. 610 V is valid at nominal AC voltage 400 VAC. If the
voltage at start is greater than 950 V, it is regulated down to 950 V where tracking is
started.

DC overvoltage monitoring
If the DC voltage is over 1000 V, the inverter gives a DC overvoltage warning and grid
connection is not allowed. The inverter may be damaged if the input voltage is higher than
1100 VDC. If the DC voltage is over 1100 VDC, the inverter gives the DC overvoltage fault.
Maximum power point tracking range
Maximum power point tracking (MPPT) range with rated Power PAC,rated is available
between 580 V and 850 V under nominal conditions and at nominal AC voltage. See
MPPT range @ PAC,rated in the figure on page 15. Maximum power point tracking operates
up to 950 V, but the available inverter maximum power between 850 V and 950 V depends
on the temperature inside the inverter.
The MPPT range operates between VMPPT_min and 950 V. The VMPPT_min is the higher
value of either the parameter 178.03 Minimum voltage ref or the voltage level that depends
on the AC voltage. The default value for parameter 178.03 Minimum voltage ref is 550 V
and nominal value for the VMPPT_min is 580 V @ 400 VAC.
The inverter topology is a single stage inverter which means that the inverter does not
have a DC / DC booster. Thus the inverter startup voltage and minimum/maximum power
point voltage depends linearly on the AC output voltage.
•If the available PV power is greater than the derated power of the inverter, MPP
tracking is disabled and DC voltage is determined by the PV curve. The inverter limits
the output power while the voltage rises, but the inverter stays connected to the grid
unless the voltage exceeds 1000 V.
•If the available PV power is smaller than the derated power of the inverter, MPP is
tracked within the operating voltage range. MPP tracking operates up to 950 V after
which the inverter clamps the DC voltage to 950 V. MPP is not allowed and will not
push the operation point above 950V.
DC current limiting
The inverter controls its output power such that the DC input current does not exceed
58 A. The lowest DC input voltage that provides maximum output power is 580 V under
nominal conditions.

Country settings
Preset country codes
The PRO-33.0-TL inverter has a country code table with preset grid code settings for 37
countries. The installation country is initially set with the First start assistant or with the
parameter 188.01 Country code.
The First start assistant activates automatically when the inverter is turned on for the very
first time. See more details in the PRO-33.0-TL Product manual. The country code may
also have separate options for low voltage and medium voltage settings when there are
separate requirements for MV connection in the same country, such as Germany LV and
Germany MV. If the country code is not set, the inverter does not operate.
When a country code is selected, all the necessary parameter settings are set to match
the country requirements. The country code settings affects the parameters in the groups
124 Q ref, 130 Limits,178 MPPT settings, 188 Grid monitoring, 189 Inverter control and
209 Misc. The parameters include, for example, nominal output values, tripping limits for
under- and overvoltage and under- and overfrequency, initial connection delays, variety of
reconnection delays, anti-islanding settings, reactive power settings, fault ride-through
settings, power limitation settings and MPPT recovery settings. Usually the country code is
not changed during the lifetime of the inverter.
You can change the country code with parameter 188.01 Country code.
Note: Changing this value will always override any changes made in the above-mentioned
parameter groups.
When a country code is initially set, all the preset parameters can be modified if they
adhere to the local grid code requirements. See details in chapter Customizing country
code settings on page 17.

Customizing country code settings
If the country code-related parameter settings (parameters in groups 124 Q ref, 130
Limits,178 MPPT settings, 188 Grid monitoring, 189 Inverter control and 209 Misc) need
to be changed, follow this procedure:
Disable the inverter
1. Enter the Service menu.
2. Select Inverter operation and press Edit.
3. Change the value from Enable to Disable and press Save. After a short period, the
inverter stops running and it is possible to change the parameter values.
Customize settings
1. Enter the parameter list: Service menu - Parameters - Complete list.
2. Check that you have a country code set with parameter 188.01 Country code.
3. Make required changes to the parameters.

Grid monitoring
The PRO-33.0-TL inverter monitors the grid conditions with internal measurements. The
measured values are compared against the limits set in the parameter group 188 Grid
monitoring. If the measured value does not stay within the limit for a certain minimum
period of time, the inverter declares the grid as unstable. All grid monitoring settings are
reset when the country code is changed.
Notes:
•If the grid monitoring settings are changed, do a parameter refresh with the parameter
188.05 Refresh.
•Depending on the installation country, an external third party-certified grid monitoring
relay may be needed.
Nominal values
Note: The fault ride-through settings must be taken into account when defining grid
monitoring.
The inverter monitors either line-to-line voltages or line-to-neutral voltages. This is
selected with the parameter 188.06 Voltage source that can be set to Main or Phase,
respectively. The settings for grid monitoring are set in relation to the nominal value.
Settings
188.02 Nominal LL voltage
188.03 Nominal phase voltage
188.04 Nominal frequency
188.06 Voltage source
Connection delays
Typically, it is required that the grid must be stable for some time before grid connection is
allowed. For this purpose there is a set of delays.
•188.10 Initial connection delay defines the delay that must expire before the first grid
connection after a power-up can be made.
•188.11 Reconnection delay defines the delay that must expire after a disconnection
before the following reconnection.
•188.13 Quick reconnection delay is used if the grid is unstable for less than the value
defined in parameter 188.12 Quick disturbance limit. Thus a short unstable grid allows
a faster reconnection. If the parameter 188.12 Quick disturbance limit is set to 0, quick
reconnection is not used.

Connection limits
The grid monitoring function of the inverter includes a connection condition checking that
is used only in a grid connection. Typically, the connection limits are stricter than the
disconnection limits. The connection limits are also referred as "cut-in" conditions.
There are connection limits for underfrequency, overfrequency, overvoltage and
undervoltage. Each phase/main voltage is independently monitored.
Settings
188.20 Connect underfrequency type
188.21 Connect underfrequency limit
188.22 Connect overfrequency type
188.23 Connect overfrequency limit
188.24 Connect undervoltage type
188.25 Connect undervoltage limit
188.26 Connect overvoltage type
188.27 Connect overvoltage limit
Voltage monitoring
There are two limits for undervoltage monitoring and three limits for overvoltage
monitoring. Each limit has an enable parameter, a limit parameter and a time parameter.
When the limit is enabled and the measured value exceeds the limit for the time, the grid is
declared as unstable. All limits are logically connected in parallel. Each phase/main
voltage is independently monitored.
Settings
188.50 Undervoltage enable 1 -- 188.71 Overvoltage time 3
Sliding overvoltage
Sliding overvoltage implements the monitoring of the slowly rising AC voltage. A
10 minutes average value is calculated and compared against the limit. Each phase/main
voltage is independently monitored.

188.73 Sliding overvoltage limit
188.74 Sliding overvoltage time
Frequency monitoring
There are two limits for underfrequency and overfrequency monitoring. Both the limits
have an enable parameter, a limit parameter and a time parameter.
When the limit is enabled and the measured value exceeds the limit for the time, the grid is
declared as unstable. All limits are logically connected in parallel.
