3.1 UNPACKING

In addition to the Sunmaster the delivery includes:

• A mounting bracket to mount the Sunmaster to a wall

• This user’s and installation manual.

After unpacking, check the contents for possible damage.
Do not use the product if it is damaged. If in doubt, contact
your supplier.

3.2 COUNTRY SELECTION

The Sunmaster is equipped with an anti-islanding device
that ensures the switch off in case of grid failure. European
countries maintain different regulations with regard to the
grid interface of solar inverters. The common islanding
device is the QNS, which switches off the inverter if the
grid voltage or frequency is out of range. In some
countries like Germany the ENS device (VDE-V-0126-1-1
compliant) is compulsory.

Because of these different regulations the Sunmaster must
be configured at first installation. See section 4.3.2.
Furthermore the Sunmaster can be supplied with or
without internal DC switch which is used to disconnect the
photovoltaic modules from the inverter, as required in
buildings by the international standard IEC60364-7-712.

Check from the part number on the type number plate
whether the Sunmaster is appropriate to be used for the
intended application (refer to table 1).

Table 1

WARNING

Never use the Sunmaster for a non-intended
application!

3.3 INSTALLATION ENVIRONMENT

The Sunmaster can be mounted in the AC distribution
cabinet or in the vicinity of the solar panels. Obey the
following stipulations during installation:

• The Sunmaster is designed for both indoor and

outdoor use, according to safety class IP44. Among
others this means that the Sunmaster should not be
exposed to direct weather conditions such as rain or
snow. Therefore the Sunmaster should at least be
installed under a canopy roof for protection against
rain.

• Do not install the Sunmaster in dusty environments.

• Ambient temperature: -20 ... 60°C; (power derating

above 45°C).

• No objects must be located within a distance of 10 cm

around the Sunmaster (figure 3).

• Make sure that the hot air that is generated during

operation will be discharged by forced ventilation when
installing the Sunmaster in a closed section.

• Keep at least 50 cm in between the inverters when

several Sunmasters are installed next to each other
(figure 5). If this is not possible, adequate measures
must be taken to avoid one inverter heating up the
other (figure 4).

• If the Sunmaster is installed in the immediate vicinity of

living areas, take into account that the Sunmaster can
produce a slight noise level when operating (refer to
section 7.1).

• Mount the Sunmaster vertically on a solid wall.

• Readability of the display is optimal when looking at

the display from an equal or lower position.

3.4 AC WIRING

The Sunmaster may only be used in a in a permanent
installation, connected to a separate AC distribution group,
to which no other electrical equipment is connected.
The cabling between the junction box or electric cable duct
and the Sunmaster must be double insulated. Use an
appropriate AC-wire diameter, so that the single wire
resistance between the Sunmaster and the AC distribution
will not exceed 0.25 Ohm. Directive: up to 25 meters
length, choose a wire diameter of 3 x 4mm². Choose a
larger wire size for lengths above 25 meter.

3.5 GROUNDING

The Sunmaster must be provided with an equipment­grounding conductor to the AC-output ground terminal.
Grounding and all other wiring must comply with local
codes and ordinances.
Grounding of the solar array is not necessary thanks to the
galvanic isolation between the DC-input and the AC output
of the Sunmaster.

3.6 SPECIFICATIONS OF THE SOLAR SYSTEM

The solar system should meet the following specifications:

• Maximum open circuit string voltage at lowest possible
temperature of the PV modules and maximum PV
power connected to the inverter:

Model Sunmaster Max voltage Max power

XS4300 550Vdc max 4600Wp
XS3200 600Vdc max 3500Wp
XS2000 450Vdc max 2100Wp

• Double insulated PV-wiring

• All cables of the string should have double insulation

and must be fitted with pre-assembled MultiContact
connectors (Ø4mm)

• If two or more strings are connected to the same
Sunmaster, both string lengths must be equal.

.

CAUTION!

Do not install the Sunmaster if the solar­system does not comply with the above
mentioned stipulations.

3.7 DC SWITCH

Depending on local applicable regulations the use of a DC
switch between the PV modules and the inverter may be
mandatory.
For example international standard IEC60364-7-712
prescribes a DC switch in solar electric installations in
buildings. For this reason Mastervolt offers several models
of the Sunmaster with integrated DC-switch. See chapter

3.2 to check if your Sunmaster is equipped with such a

DC-switch.

If your Sunmaster is not equipped with a DC-switch, an
external DC-Switch can be applied. Single and double
output types are available rated 600 Volts and 25A. See
chapter 8 for ordering information.

3.8 PV MODULES AND STRINGS

The solar or DC side of the system consists of several
photovoltaic (solar) modules, further mentioned as “PV
modules”. The PV-modules are connected in series to
form a so called “string”. These strings consist of a plus (+)
and a minus (–) connection which can be connected
directly to the Sunmaster.
The string voltage should be equal to the open circuit
voltage (Voc) per PV module (refer to the specifications of
the PV-module), multiplied by the number of PV-modules
in each string. Depending on the solar irradiation and
temperature, this value should be equal to 70-95% of the
calculated string voltage.

The Sunmaster is equipped with a single MPP tracker and
two parallel string connections, see figure 6.

3.8.1 Connection of two strings (standard)

Two strings can be connected to the Sunmaster directly.
See section 3.6 for the maximum power connected to
each Solar-input. The total input power must be distributed
equally over both Solar-inputs as much as possible.
See figure 7.

3.8.2 Connection of more than two strings
(option)

In case more than two strings should be connected to the
Sunmaster, Multicontact Y-adapters may be used to
combine the strings (see figure 8 and ordering information
chapter 8). The strings connected to the same Solar-input
should exist of an equal number of identical PV-modules.
See figure 9.

5 OPERATION

5.1 GENERAL

After installation and commissioning the Sunmaster will
switch on automatically if solar irradiation is sufficient. The
Sunmaster operates automatically: there is no need for
user action. If the irradiation of the PV-modules is
insufficient, for instance at night, the Sunmaster switches
off automatically. When switched off, the display does not
show any information.

The Sunmaster has no ON/OFF switch; In the event of
decommissioning, refer to section 4.4.

CAUTION!

Never disconnect the MultiContact plugs
during operation of the Sunmaster.
Not complying with this instruction may cause
a spark or an electric arc. Should an arc
develop, both plug and socket of the
Sunmaster must be replaced.

5.2 FORCED COOLING

For an optimum internal temperature control the
Sunmaster is provided with a cooling fan. The cooling fan
starts running slowly at inverter start up. As internal
temperature rises, the cooling fan will increase its speed.
This is a normal effect which has a positive contribution to
the efficiency and lifetime of the Sunmaster.

5.3 LCD-DISPLAY

The Sunmaster is standard provided with an integrated
LCD-display at the front side of the cabinet (figure 23).

This display makes it possible to monitor the performance
of your PV-system. It shows the following information:

5.3.5 Failures

As long as the ERROR LED isn’t illuminated,
no failure is detected: the Sunmaster is
operating normally!

If the irradiation of the PV-modules is
insufficient, for instance at night, the
Sunmaster switches off automatically and the
display does not show any information. This is
a normal situation!

Figure 29: representation of a failure

The operation of the Sunmaster is controlled and checked
by a microprocessor. If an error occurs, it is detected by
the apparatus itself: the red ERROR LED illuminates or
blinks. The cause of error is displayed by means of an
error code. See figure 29. Refer to chapter 6 for
explanation of the error codes.

5.4 MAINTENANCE

No specific maintenance to the Sunmaster is required.
Examine your electrical installation on a regular base, at
least once a year. Defects such as loose connections,
burnt wiring etc. must be corrected immediately.
If necessary, use a soft clean cloth to clean cabinet of the
Sunmaster. Never use any liquids, acids and/or scourers.

ITLAY SELF TEST

EN / Sunmaster XS4300-3200-2000 / November 2008 23

9 ITALY SELF TEST

GENERAL

The Italy Self Test is meant to check the upper
and lower limits of the AC voltage and AC
frequency at which the inverter will disconnect
from the grid.

To enter the Italy self test, select the
“System/ Model” menu in the display.
See figure 31.
If the model is ITALY, press the lower two
buttons for 3 seconds. The screen should stay
in the “Model” mode. You will enter the Italy
test menu.

The text ITALY TEST will be blinking, press the
lower right button to confirm.
First the Uac High Off limit is shown.

During the self test, four tests are done in this
sequence:

UH (high off limit AC voltage);
UL (low off limit AC voltage);
FH (high off limit AC frequency);
FL (low off limit AC frequency).

After each test the user has to confirm the test
result before the inverter starts the reclosure
count down and reconnects to the grid.

After the last test and after reconnecting to the
grid the inverter will continue in normal
operation.

The test accuracy is better than 1V/ 0.1Hz if
grid voltage and frequency are stable.

Figure 31

The standard reclosure time of
300 sec has been reduced to
10 sec to shorten the testing
time. This is not an error.

After the UL-test, TIME, UG and UT show in the screen successively.
UT is the measured value of UL.

Write down TIME, UG and UT. After confirming, all values
disappear from the display to start the next test.

Calculation by hand: UT = UG – (TIME * 11.5).
Example: if UG = 230V and TIME = 4.00 s,
UT = 230 -
