HOW IT WORKS

EN / SunMaster CS15TL/CS20TL / August 2010 7

3 HOW IT WORKS

See figure 3. A string box combines multiple PV stings to two solar inputs. The CS15TL/CS20TL inverts the DC solar inputs to one 3-phase 3 x 400 V AC output. Both inputs and output are filtered from voltage ripples. For the operating voltage range refer to the specifications. The AC outputs are connected in a 400 V AC three-phase delta configuration. An isolation transformer between the

inverter and the grid is an option. Anti- islanding is provided according to national standards. If one of the phases of the AC grid fails in operation, the CS15TL/CS20TL will switch off immediately. Extended diagnostics via remote monitoring may be ordered as an option.

Figure 3: Schematic example of the CS15TL/CS20TL in a PV plant

3.1 WORKING PRINCIPLE OF THE CS15TL/CS20TL

See figure 3. The CS15TL/CS20TL converts the energy from a PV array and feeds this energy back to the electric grid. The electrical components in the CS15TL/CS20TL are housed in an IP65 compartment with IP44 cooling compartment.

3.2 GRID INTERFACE

The gird interface consists of a number of safety systems:

• VFM (Voltage and Frequency Monitoring);

• RCD (Residual Current Detection);

• DCD (Direct Current Detection);

• Controlling redundant AC relays for each grid phase.

3.3 OPTIMA COOLING

For an optimum internal temperature control the CS15TL/CS20TL is provided with four cooling fans. These fans start running slowly at inverter start up. Fan speed os controlled by internal temperature and output power. If internal temperature rises, the cooling fans will increase their speed. This is a normal effect which enhances the CS15TL/CS20TL efficiency and lifetime.

3.4 MONITORING

The CS15TL/CS20TL is equipped with a display for monitoring on location. However, remote monitoring is an option too, using the internet. See also chapter Operation. If you opt for remote monitoring, please contact your Mastervolt supplier.

When lifting the CS15TL/CS20TL avoid any risk of personal injuries, do not stand under the CS15TL/CS20TL.

4.2 APPARATUS SETTINGS

The CS15TL/CS20TL is equipped with an anti-islanding device that ensures instant disconnection in case of grid failure. European countries maintain different regulations with regard to anti-islanding devices and grid connection of distributed generation in general. The common islanding device switches off the inverter if the grid voltage or frequency is out of range. The CS15TL/CS20TL is set to local regulations by setting the country in the configurations menu. This setting is password protected. Contact your Mastervolt distributor in case the settings need to be changed.

CAUTION!

NEVER connect the CS15TL/CS20TL to a utility grid other than specified, refer to chapter 10.

4.3 INSTALLATION ENVIRONMENT

Obey the following stipulations during installation:

• The CS15TL/CS20TL is designed for both indoor and

outdoor use, safety class is IP65.

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

above 40°C).

• Keep at least 50 cm space around the

CS15TL/CS20TL, fig 4.

• If the CS15TL/CS20TL is installed in the immediate

vicinity of living areas, take into account that it can produce a certain noise level when operating.

• Mount the CS15TL/CS20TL vertically to a solid wall.

CAUTION!

Do not install in aggressive environments like ammonium, acids and salt air.

CAUTION!

Do not install in areas that are subject to the risk of gas- or dust explosions.

4.4 LIGHTNING PROTECTION

In a solar installation, precautions must be taken to avoid damage from induced surges caused by lightning. The CS 15/20 TL is equipped with class III (mcro) protection against over voltages on all DC, AC and communication in/ outputs. Additional (external) surge protection of these in/ outputs is strongly recommended. StringMaster string boxes featuring a class II surge protection are available from Mastervolt. Suitable surge arrestors (varistors) must be installed near the inverter (<10 m).

EN / SunMaster CS15TL/CS20TL / August 2010 9

4.5 DC CONFIGURATION

The solar or DC side of the system consists of several photovoltaic (solar) modules, further referred to as “PV modules”. The PV modules are connected in series to form a so called “string”. These strings have a plus (+) and a minus (–) connection which can be connected to the CS15TL/CS20TL via a string combiner box, eg. the Mastervolt StringMaster.

4.5.1 Separate or parallel inputs

The CS20TL has two separate inverters with an own input each, called Input 1 and Input 2. These inputs can be used as separate inputs (normal situation) or they can be configured in parallel. See figures and table for the applications.

Separate inputs Parallel operation

Per input different string lengths possible.

For uneven numbers of

strings. Per input max 13 kWp. MPP current above 30A. Per input different PV module positions possible.

For PV grounding. Refer to

section 6.5.1. Per input different module types possible.

Figure 5: Separate inputs and parallel operation

4.5.2 Specifications of the PV installation

The PV installation should meet next specifications:

• The maximum open circuit string voltage for each power module at lowest possible temperature of the PV modules may not exceed 1000V.

• Double isolated PV cabling, fitted with MultiContact 4mm type connectors must be used.

• The maximum power connected to the CS15TL may not exceed 10 kWp per input or 19 kWp in total.

• The maximum power connected to the CS20TL may not exceed 13 kWp per input or 25 kWp in total.

• All connection devices (wiring, terminal blocks, fuse holders, fuses, switches etcetera) must be rated for the applicable voltage (up to 1000V DC) and current ratings (up to 30A DC) of the solar installation.

Do not install the CS15TL/CS20TL if the solar-system does not comply with the stipulations mentioned above!

4.6 DC SWITCH

For safety reasons, the use of a suitable DC siwtich is recommended. Depending on local applicable regulations the use of a DC switch between the PV modules and the power modules may be mandatory. The DC switch is included in the optional StringMaster CS 2-6 SW.

4.7 THREE PHASE AC CONFIGURATION

The CS15TL/CS20TL is intended for use in a permanent installation, connected to a separate three phase AC distribution group, to which no other electrical equipment is connected. All electrical connections must comply with local codes and regulations. The AC output is arranged in a 400 V AC three-phase delta configuration. Use a suitable cross section, so that the cable loss is well below 1%. The recommended cross section for a 10 m cable is 4,0 mm².

4.8 POWER MANAGEMENT

The CS15/20TL has a power management function built in. It enables a grid operator to send a request for delivering less power to the grid. For this purpose, an optional DataControl Premium or DataControl Pro II is connected to the inverter via RS485. The grid operator sends his request to the datalogger that triggers the Power Management function. In case such a request is done, the display shows the reduction value in the home screen. Example: ON, Pwr Mgmt 30 % means maximum 70% of the nominal output power should be delivered. For all power reduction values, see chapter 9. Contact your Mastervolt supplier for more information.

5.3 MASTERBUS CONNECTORS

The CS15TL/CS20TL is equipped with 2 x 2 MasterBus connectors (A and B) to install two MasterBus networks. Network A is reserved for the string box connected to the CS15TL/CS20TL. The other network (B) is reserved for future upgrades.

Figure 10: RS485 and MasterBus connections

Proceed as follows to remount the communication module:

• Close any unused holes in the glands, using the premounted caps.

• Insert communication module, using the guidance rails.

• Fix the Phillips screws at both sides of the front plate

(see figure 4).

For MasterBus connection of the CS-IT20 isolation transformer, refer to section 6.6.

The CS15TL/CS20TL is compatible with the Sunmaster XL and XS inverter series, so it can be combined with these inverters in the MasterBus network.

5.4 MASTERBUS NETWORK

All devices that are suitable for MasterBus are marked by the MasterBus symbol.

MasterBus is a fully decentralized data network for communication between the different Mastervolt system devices. The communication network is based on CANbus which has proven a reliable bus-system. New devices can be added to the existing network by just extending the network. This gives the MasterBus network a high degree of flexibility for extended system configuration. Mastervolt

also offers several interfaces, making even non-MasterBus devices suitable to operate in the MasterBus network.

CAUTION: Never connect a non-MasterBus device to the MasterBus network directly! This will void warranty of all MasterBus devices connected.

5.5 HOW TO SET UP A COMMUNICATION NETWORK

Every device that is suitable for the RS 485 and MasterBus network is equipped with two data ports. When two or more devices are connected using these ports, together they form a local data network.

Keep the following rules in mind:

Figure 11

Figure 12

MasterBus needs a terminating device on both ends of the network. This is not needed for RS485.

An isolation transformer may be necessary for two purposes.

1. PV plant grounding (section 6.5.1);

2. Prevention of RCD tripping (section 6.5.2).

6.5.1 PV Array Grounding

Grounding of your CS20TL is necessary. This is possible at the AC side, see figure 18. Some PV panel suppliers prescribe connection of PE to the positive or minus DC input. In this case, follow next steps.

• To avoid inverter damage, a high power isolation

transformer like the CS-IT20 must be installed at the AC side.

• The DC inputs must be paralleled

• Connect the Protective Earth (PE) to the positive or

negative DC input.

• Switch off the Insulation Fault detection. See the CS-

IT20 manual for more information. Figure 18 shows the scheme for applying the isolation transformer in your PV plant.

Figure 18: PE at DC input isolation transformer

6.5.2 High solar array capacity

A high solar array capacitance may exist to the PV frame or support structure (PE). The CS20TL has been designed to withstand solar array capacities up to 4 µF. Capacities exceeding this value may cause the internal RCD to trip, installing an isolation transformer is necessary.

6.5.3 MasterBus connections

The CS-IT20 transformer is equipped with a MasterBus relay for MasterBus controlled switching. Network A is used for this purpose. Refer to figure 18 and chapter 5.

6.6 DC DISTRIBUTION

The CS15TL/CS20TL has two independent solar inputs. To accommodate more than two strings, a StringMaster string box is available especially for the CS15TL/CS20TL. Refer to the StingMaster manual for installation instructions. To release the MultiContact connectors, use of the special MultiContact tool is recommended. When more than three stings are paralleled, they must be fused. For fuse ratings refer to specifications of used fuse. All strings connected to the same Solar-input should consist of an equal number of identical PV modules. Measure the solar voltage for each input. The calculated string voltage equals the open circuit voltage (Uoc) 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, the measured string voltage amounts to 70-95% of the calculated value.

Note that the maximum power connected to each Solarinput shall not exceed 13 kWp for the CS20TL and 10 kWp for the CS15TL. The total input power must be distributed equally over the two Solar-inputs as much as possible.

INSTALLATION AND COMMISSIONING

16 August 2010 / SunMaster CS15TL/CS20TL / EN

6.7 COMMISSIONING AFTER INSTALLATION

To check the correct operation of the CS15TL/CS20TL, commissioning should be carried out during daytime only.

6.7.1 Switching on

Follow these steps to switch On the CS15TL/CS20TL: 1 Check whether the DC switches (if applied) are in the

OFF position. 2 Check AC and DC cabling and connectors. 3 Move the DC switch (if applied) of the solar array to

the ON position.

As long as the CS15TL/CS20TL is not configured in accordance with the local regulations for grid connection, it will stay in Standby mode. This means that no power can be converted.

4 If applicable, switch on the AC grid. 5 Select language and country, using the display. See

chapter 8. 6 Set the day and time. 7 Check the PV input DC voltage and the AC voltage at

the grid side of the AC circuit breaker using the

display multimeter menu. The AC voltages should be

as follows:

L1 N 230V AC +/- 10% L2 N 230V AC +/- 10% L3 N 230V AC +/- 10% L1 L2 400V AC +/- 10% L2 L3 400V AC +/- 10% L3 L1 400V AC +/- 10%

If DC and AC voltages are within range and solar irradiation is sufficient, the CS15TL/CS20TL will switch on automatically. This may take a few minutes.

6.8 DE-COMMISSIONING

If it is necessary to put the CS15TL/CS20TL out of operation, follow the instructions in order of succession as described below:

CAUTION!

Follow below mentioned instructions in order of succession as described.

1 Cut off the grid voltage by switching off the AC circuit

breaker 2 Switch Off the DC switch 3 Release the AC connector 4 Release the CS15TL/CS20TL MultiContact

connectors, using the MultiContact tool

Now the CS15TL/CS20TL can be demounted in a safe way.

CAUTION!

Never release the MultiContact plugs during operation of the CS15TL/CS20TL. A spark or an electric arc may develop, in which case both plug and socket of the CS15TL/CS20TL must be replaced.

OPERATION

EN / SunMaster CS15TL/CS20TL / August 2010 17

7 OPERATION

7.1 GENERAL

After installation and commissioning the CS15TL/CS20TL will switch on automatically if solar irradiation is sufficient. The CS15TL/CS20TL operates automatically: there is no need for operating it. If the irradiation of the PV modules is insufficient, for instance at night, the CS15TL/CS20TL switches off automatically. The LCD screen however still functions, as long as AC is available.

7.2 REMOTE MONITORING

Mastervolt provides several monitoring solutions like PC software, dataloggers, remote monitoring and so on. Consult www.mastervolt.com/Solar for a comprehensive overview of all possibilities.

7.3 MAINTENANCE

If necessary, use a soft clean cloth to clean the enclosure of the CS15TL/CS20TL. Never use any aggressive ofr abrasive cleaning agents.

7.3.1 Air outlet

The CS15TL/CS20TL is provided with wire mesh behind the air outlets (fig. 1 point 7).

Remove the two air outlets by unscrewing the two Phillips screws on top. Check the wire mesh at least every 12 months. Clean if necessary.

7.3.2 Fan module

The fan module (figure 21) also needs checking and cleaning every 12 months. Unscrew the 4 hand screws like indicated. Carefully move out the fan module, bottom first and unplug the four fans before removing the module completely. If necessary, clean the fans using compressed air.

Figure 22: Fan module with hand screws

7.3.3 Electrical connections

12.1 SELF TEST FUNCTION

Uac Max-TEST (Uac Min-TEST)

The screen shows:

• Measured value: Mval = the actual grid voltage;

• Setting: Set = the set maximum / minimum

voltage limit of the inverter.

• Time to shut down: Time = test time indication

• Calculated setting: Cset = the calculated maximum / minimum

voltage limit of the inverter

During the test the high voltage limit is changed with rate -11.5V/sec (+11.5V/sec) until it reaches the actual grid voltage. The inverter will disconnect.

After the test, the result is shown.

Write down all values shown. After pressing Confirm, all values disappear from the display to start the next test.

Calculation Uac Max by hand: Cval = Mval + (TIME * 11.5). Calculation Uac Min by hand: Cval = Mval - (TIME * 11.5).

GENERAL

The Self Test Function 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 Self Test, enter the country selection menu in the Grid Interface menu and choose Italy. In the Grid Interface, select the Self Test menu.

During the self test, next tests are possible:

Uac Max (high off limit AC voltage); Uac Min (low off limit AC voltage); Fac Max (high off limit AC frequency); Fac Min (low off limit AC frequency).

After each test you have to press Confirm before the inverter starts the reclosure count down and reconnects to the grid.

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

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

The screen shows:

• Measured value: Mval = the actual grid frequency;

• Setting: Set = the set maximum (minimum)

frequency limit of the inverter.

• Time to shut down: Time = test time indication

• Calculated setting: Cset = the calculated maximum (minimum)

voltage limit of the inverter

During the test the high (low) frequency limit is changed with rate -

0.05Hz/sec (+0.0Hz/sec) until it reaches the actual grid frequency. The inverter will disconnect.

After the test, the result is shown.

Write down all values shown. After pressing Confirm, all values disappear from the display to start the next test.

Calculation Fac Max by hand: Cval = Mval + (TIME * 0.05). Calculation Fac Min by hand: Cval = Mval - (TIME * 0.05).
