3 INSTALLATION AND COMMISSIONING

3.1 Apparatus version 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 anti-islanding devices and the supply of energy back to the utility grid in general. 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 (VDE0126 compliant) which also measures the grid impedance, is compulsory. Mastervolt can provide both the QNS and the ENS versions of the Sunmaster. Both versions are available as several variants, suited to locally regulations. Check from the part number on the type number plate whether the version of the Sunmaster is appropriate to be connected to the local utility grid. Refer to table 1:

WARNING! Never connect the Sunmaster to a utility grid which is not suitable for the use of the apparatus!


3.2 Mounting and installation 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 indoor use only, according to safety class IP23. • Ambient temperature: -20 ... 50°C; (power derating above 40°C) • Humidity: 0-90% non condensing • Do not install the Sunmaster in environments where there is heavy dust

development. • 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 4.4).

• Mount the Sunmaster vertically on a solid wall. • The Sunmaster must be mounted in such a way that obstruction of the airflow

through the ventilation openings is prevented • No objects must be located within a distance of 10 cm around the Sunmaster. • Keep at least 30 cm in between the inverters when several Sunmasters are

installed next to each other. • Make sure that the hot air that is developed during operation will be discharged by

forced ventilation when installing the Sunmaster in a closed section. • Choose an appropriate AC-wire diameter, so that the 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 2.5 mm². Choose a larger wire size for lengths above 25 meter.

The AC/DC and grounding cables are connected at the bottom side of the cabinet. If necessary, the cabling can be fed from the top to the bottom side of the cabinet along the backside of the cabinet. Determine the mounting spots on the basis of figure 7 - outline drawing Sunmaster on page 23. Use suitable screws and dowels to fix the Sunmaster to the wall. Turn the mounting screws already into the wall. Place the cabinet over the screws. Then fasten the screws.


3.2.1 Use of spring-cage terminal blocks Depending on the model, the Sunmaster is equipped with spring-cage terminal blocks to connect the AC- and DC-wiring. Use a maximum wire diameter of 4mm² (stranded cable with cord end terminals) or 6mm² (hard-core wire) to fix to the AC and DC spring-cage connections. Strip the cable insulation 8-10mm. Use an insulated 4mm flat blade screwdriver to open the spring-cage clamp. CAUTION! Connect the wiring to the spring-cage terminals as stated in figure 1.

upper slot, as indicated in figure 1.

2 Move screwdriver upwards until connector has opened completely.

3 Place cable into opening and pull back screwdriver.


3.3 Connection of solar (DC) cabling 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 one or two strings. These strings consist of plus (+) and a minus (–) connections that can be connected directly to the Sunmaster. The Sunmaster is suited to connect two strings maximum, both existing of an equal quantity of identical PV-modules. The connection procedure described below incorporates several measurements which can only be carried out when sufficient irradiation is present. Installation should therefore be carried out during daytime only. CAUTION! • Short circuiting or reversing polarity may lead to damage to the Sunmaster, the

cabling and/or the terminal connections. • Follow all steps of the installation instructions in order of succession as described Depending on the model of the Sunmaster, the DC cabling can be connected in two ways: either using MultiContact connection material (refer to section 3.3.1 and figure 2) or directly onto the spring-cage terminal blocks on the power board inside the cabinet, by feeding the cabling through the cabinet’s cable glands (refer to section 3.3.2 and figure 3).

3.3.1 DC connection by means of MultiContact connectors

In this case the Sunmaster is equipped with four MultiContact contra plugs: two string connections each consisting of a plus (+) and a minus (–) connection. MultiContact connection material is touch proof and can be connected to the Sunmaster directly. 1 Check the voltage and polarity of each string with a suitable DC Voltmeter.

Connect the measuring pins to the corresponding plus (+) and minus (–) plug of each string. This voltage should be equal to the open circuit voltage (Voc) per PV module (refer to the specifications of the modules), multiplied by the number of modules in each string. Depending on the solar irradiation, the measured value should be equal to 70-95% of the theoretically calculated value. To match the specifications the measured voltage should be between 190 and 450VDC for Sunmaster QS1200 models and between 210 and 450VDC for Sunmaster QS2000 models

2 In case of two strings (which must be identical), check whether the two measured values are nearly identical (maximum deviation: 5%).

3 Check for each string the leakage current to ground. Measure the leakage current with a suitable meter (mADC) between the plus (+) connection and ground and the minus (–) connection and ground for each string. This value must be 0 (or less than 1mA).

4 Connect the MultiContact plugs of the string cabling to the corresponding contra plugs on the Sunmaster (Refer to figure 2: [9] for the plus (+) connections and [10] for the minus (–) connections).


5 If only one string is connected, the unused MultiContact contra plugs should be covered using the supplied caps.

6 When the DC-cabling has been installed correctly, some indication LEDs on the front panel will illuminate, indicating that the AC side has not yet been connected: - Both the red LED (diagnostic) and the yellow LED (0% / general fault) illuminate - With the ENS versions the yellow LED (50% / grid quality) illuminates as well.

WARNING! 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.

Figure 2: Connection of the DC-cabling using MultiContact connection material


3.3.2 Direct connection of the DC cabling onto the power board WARNING! The voltages present on the DC-cabling of the PV modules are high (up to 450 VDC) and cannot be switched off. The stripping and connection of the cabling should therefore be carried out with the utmost care and suitable tools. The voltages of the DC system are floating (class II): there is no connection to ground. This means that when one of the string connections (plus or minus) is accidentally touched, this will not directly lead to personnel harm or accidents. However, this should be avoided in any case! Short circuiting of the plus (+) and minus (–) connections must be avoided at any cost! Follow in detail all steps of the installation instructions in order of succession as described below:

1 Open the connection area at the bottom side of the cabinet. To do so, loosen the

two screws at the bottom side and slide the front cover plate from the cabinet. 2 The cabinet is fitted with four glands for the DC cabling (refer to figure 3, parts [9]

and [10]). Feed one non-stripped DC cable per gland into the cabinet. 3 Open the orange lids of both DC separators (part [4] in figure 3). 4 Strip approx. 8 mm of the plus (+) cable of string 1 with appropriate tools and

connect the cable to the first plus (+) PCB connector (part [2] in figure 3). This is a spring-cage terminal block that can be opened using a flat blade screwdriver (see section 3.2.1 and figure 1). Check the connection by pulling the cable.

5 Repeat this for the minus (–) connection of string 1 and connect the cable to the first minus (–) PCB connector on the PCB (part [3] in figure 3).

6 Check the voltage and polarity of the string with a suitable DC voltage meter. To do so, insert the voltmeter’s measuring pins into screw driver’s opening of the terminal block. This voltage should be equal to the open circuit voltage (Voc) per PV module (refer to the specifications of the modules), multiplied by the number of modules in each string. Depending on the solar irradiation, the measured value should be equal to 70-95% of the theoretically calculated value. To match the specifications the measured voltage should be between 190 and 450VDC for Sunmaster QS1200 models and between 210 and 450VDC for Sunmaster QS2000 models

7 In case of two strings, repeat steps 4, 5 and 6 for the second string. At similar circumstances (equal solar irradiation) the measured voltage of the second string must be near to the measured voltage of the first string (maximum deviation: 5%)

8 Check for each string the leakage current to ground. Measure the leakage current with a suitable meter (mADC) between the plus (+) connection [2] and ground and the minus (–) connection [3] and ground for each string. This value must be 0 (or less than 1mA).

9 Close both DC separators by pushing the orange lids back in position (part [4]). Be sure to lock these separators firmly. Beware: a loose or unreliable contact may result in a defective Sunmaster!


10 When the DC-cabling has been installed correctly, some indication LEDs on the front panel will illuminate, indicating that the AC side has not yet been connected: - Both the red LED (diagnostic) and the yellow LED (0% / general fault) illuminate - With the ENS versions the yellow LED (50% / grid quality) illuminates as well

11 Tie the cabling together using a tie-rap directly after the glands, inside the cabinet. Tighten the glands (parts [9] and [10] in figure 3) to ensure the pull relief.

Figure 3: Direct connection of the DC-cabling onto the power board


3.4 Connection of the AC cabling 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 AC-wire diameter of 3 x 2.5 mm² at least. Depending on the model of the Sunmaster, the AC cabling can be connected in two ways: by means of a Powercon connector (see section 3.4.1 and figure 4) or directly on the power board inside the cabinet (refer to section 3.4.2 and figures 2 and 3). In the latter case the cabling is led through the cabinet’s cable glands

3.4.1 AC connection by means of a Powercon connector

1 Switch off the AC voltage by means of the AC distribution switch in AC distribution cabinet.

2 Connect the AC cable to the Powercon connector according to figure 5. 3 Switch on the AC voltage again and check the voltage on the Powercon connector. 4 Plug the Powercon connector into the corresponding contra plug at the bottom

side of the cabinet (refer to figure 4). CAUTION! Never disconnect the Powercon connector during operation of the Sunmaster. Not complying with this instruction may cause damage to the Sunmaster and/or to the Powercon connector.

3.4.2 Direct connection of the AC cabling on the Power Board 1 Cut off the AC voltage by switching off the AC distribution switch in the AC

distribution cabinet. 2 Feed the AC cabling through the gland into the cabinet (part [8] in figure 2/3). 3 Connect the AC-cabling to the corresponding terminal blocks on the power board

(L, N and PE). This is a spring-cage terminal block that can be opened using a flat blade screwdriver (see section 3.2.1 and figure 1).

4 Tighten the gland to ensure the pull relief. 5 Switch on the AC voltage again and check with an adequate multimeter whether

the voltage is present at the terminal block 6 Close the connection area of the Sunmaster.

3.5 Grounding cable If you make a connection between the PV-modules and the ground, you need to lead the grounding cable together with the DC-cables to the Sunmaster and then to the AC distribution. Make a connection between the grounding cable going from the PV-modules to the AC-distribution and the cabinet of the Sunmaster. For this purpose a grounding terminal is situated at the bottom side of the cabinet (part 7 in figure 4)

3.6 Installation of the QS-Display (optional) The optional QS-Display comes with a front cover plate. To install the QS-Display, replace the standard front cover plate by the QS-display cover plate 1 Open the connection area at the bottom side of the cabinet. To do so, loosen the

two screws at the bottom side and slide the front cover plate from the cabinet 2 Connect the QS-Display to the display connector (part 11 in figure 2/3) by means

of the flatcable provided. Lead the flatcable through the right hand side of the connection area, avoiding the cable from touching the fan or DC-cabling.

3 Fix the front cover with integrated QS-Display onto the connection area and tighten the two screws again.

4 If the QS-Display is connected correctly, the text “QS1200” or “QS2000” (model dependent) appears in the display.

5 Store the original front cover along with the users manual of the Sunmaster.

3.7 Commissioning If connection has been made correctly and solar irradiation is sufficient, the Sunmaster will switch on automatically: • The red indication LED (diagnostic) on the front panel will stay illuminated for 10

up to 300 seconds (reclosure time, depending on the model); meanwhile the yellow LED (0% / general fault) will flash. With the ENS versions of the Sunmaster the yellow LED (50% / grid quality) is illuminated as well.

• Next the red LED will extinguish and the yellow LED (0%) flashes for 5 seconds, indicating a self test

• Now the Sunmaster switches on. The LED-bar displays an indication of the energy that is generated by means of your PV-modules.


Figure 6: LED-bar

4 OPERATION After installation the Sunmaster will switch on automatically if solar irradiation is sufficient. The Sunmaster operates automatically: there is no need for adjustment or operation.

4.1 LED-bar The Sunmaster is standard provided with an integrated LED-bar (figure 6) at the front side of the cabinet. Under normal circumstances the LED-bar indicates the amount of power that is fed into the grid by the Sunmaster: the more LED’s illuminate, the more power is converted. After connection of the PV-modules and during sunrise a system check is carried out, indicated by the illumination of several LED’s. This system check takes up to 15 seconds. In case of a system failure, the cause of the failure is displayed by means of a combination of illuminating LEDs: the red ‘diagnostic’ LED illuminates in combination with one or more yellow LEDs. Refer to table 2 (chapter 6) for an explanation of the power- and failure indications. 4.2 QS Display (optional) The QS Display can easily be installed in the Sunmaster. It enables the user to monitor the daily yields for the last 20 days, the total energy and operating hours, and a variety of actual readings. Refer to the users manual of the QS Display for extended operating instructions.

4.3 Monitoring

The Sunmaster has two RJ-45 connectors that can be connected to the QS Databus. Mastervolt provides several monitoring solutions like PC software, dataloggers, remote monitoring and so on. Consult our web-site at www.mastervoltsolar.com for a comprehensive overview of all possibilities.

4.4 Forced cooling For an optimum internal temperature control the Sunmaster is provided with a cooling fan. Depending on circumstances, the cooling fan starts running slowly at approximately 50% of the nominal power. 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 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.

6 FAILURES 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 indication LED (diagnostic) at the front of the cabinet will illuminate. If the irradiation of the PV-modules is insufficient, the Sunmaster switches off automatically. When switched off, none of the LED indications will illuminate. As long as the the red indication LED isn’t illuminated, no failure is detected: the Sunmaster is operating normally. When the red indication LED illuminates, a failure of the electrical installation or the Sunmaster is detected. The cause of failure is displayed by means of a combination of one or more illuminating yellow LED’s. Refer to table 2 for explanation of the error codes. Consult an installer, if you cannot solve the problem by means of the table below.

7 DECOMMISSIONING AND DEMOUNTING The Sunmaster can only be put out of operation if no power is converted to the public grid. To put the Sunmaster out of operation, follow the instructions in order of succession as described below:

7.1 AC switch off Cut off the AC voltage by switching off the AC distribution switch in the AC distribution cabinet before decommissioning or demounting the Sunmaster. Check whether both the red indication LED (diagnostic) and the yellow LED ‘0% / general fault’ illuminate (with the ENS versions the yellow LED ‘50% / grid quality’ illuminates as well). CAREFUL Always switch off AC voltage before decommissioning or demounting the Sunmaster.

7.2 Disconnection of AC cabling Depending on the model of the Sunmaster, the AC cabling can be disconnected in two ways: by means of a Powercon connector (see section 7.2.1) or by removing the AC cabling from the power board inside the cabinet (refer to section 7.2.2).

7.2.1 Disconnecting AC by means of a Powercon connector Pull the Powercon connector from the socket by turning the locking ring counter clockwise simultaneously.

7.2.2 Disconnection of direct AC cabling from the power board 1 Open the connection area at the bottom side of the cabinet. To do so, loosen the

two screws at the bottom side and slide the front cover plate from the cabinet. 2 Loosen the cable glands. 3 Remove the AC wiring from the terminal blocks (L, N en PE) by opening the spring

cage clamps with an insulated 4mm flat blade screwdriver (see figure 1).

7.3 Switching off DC voltage Switch off the external DC switch, if such is applied in the installation. Use extra caution and pay careful attention while removing the DC (solar) cabling if no external DC switch is applied.

7.4 Disconnection of DC (solar) cabling Depending on the model of the Sunmaster, the DC cabling can be disconnected in two ways: either by removing the MultiContact connectors (refer to section 7.4.1 and figure 2) or by disconnecting the wiring directly from the spring-cage terminal blocks on the power board inside the cabinet (refer to section 7.4.2 and figure 3).

7.4.1 Disconnecting DC cabling by means of MultiContact connectors MultiContact connection material is touch proof. Remove the MultiContact connectors one by one from the Sunmaster.


7.4.2 Disconnecting DC cabling directly from the power board WARNING! Hazardous voltages are present on the DC-cabling. Therefore the DC-cables must be disconnected and isolated one by one. The voltages present on the DC-cabling of the PV modules are high (up to 450 VDC) and cannot be switched off. The voltages on the DC side of the system are floating (class II): there is no connection to ground. This means that when one of the string connections (plus or minus) touched accidentally, this will not directly lead to personnel harm or accidents. However, this should be avoided in any case! Short circuiting of the of the plus (+) and minus (–) connections must be avoided at any cost Follow in detail all steps in order of succession as described below: 1 Open the connection area at the bottom side of the cabinet. To do so, loosen the

two screws at the bottom side and slide the front cover plate from the cabinet. 2 Open the orange lids of both DC separators (part [4] in figure 3). 3 Remove the DC-cable at the leftmost position from the terminal block by opening

the spring cage clamps with an insulated 4mm flat blade screwdriver (see figure 1) 4 Isolate the core of the wires with insulating tape. 5 Repeat steps 3 and 4 to remove all other DC-cables by removing and isolating

each cable one by one.

7.5 Transportation Always use the original package for transportation.
