5.1 Selecting the appropriate grid standard

5.1.1 Verifying grid standard for country of installation

Canadian Solar inverters are used worldwide and feature preset standards for operating on any grid. Although the grid standard is set at the factory, it is essential the grid standard be verified for the country of installation before commissioning.

The menu for changing the grid standard or for creating a custom standard is accessible as described in Section 6.7 and below.

WARNING

Failure to set the correct grid standard could result in improper operation of the inverter, inverter damage or the inverter not operating at all.

5.2 Changing the grid standard

5.2.1 Procedure to set the grid standard

NOTE

This operation is for service technicians only. The inverter is customized according to the local grid standard before shipping. There should be no requirement to set the standard.

NOTE

The "User-Def" function can only be used by the service engineer.

Changing the protection level must be approved by the local utility.

5.4 Preliminary checks

WARNING

High Voltage.

AC and DC measurements should be made only by qualified personnel.

5.4.1 DC Connections

Verify DC connections.

1 ). Lightly tug on each DC cable to ensure it is fully captured in the terminal.

2). Visually check for any stray strands that may not be inserted in the terminal.

3). Check to ensure the terminal screws are the correct torque.

5.4.2 AC Connections

Verify AC connections.

1 ). Lightly tug on each AC cable to ensure it is fully captured in the terminal.

2). Visually check for any stray strands that may not be inserted in the terminal.

3). Check to ensure the terminal screws are the correct torque.

5.4.3 DC configuration

Verify DC configuration by noting the number of panels in a string and the string voltage.

5.4.3.1 VOC and Polarity

Measure VOC, and check string polarity. Ensure both are correct and VOC is in specification.

5.4.3.1.1 Check string voltage

To measure the open circuit voltage (VOC) and polarity of the individual strings, perform the following steps:

WARNING

When the fuse holders are closed, parallel strings on the same MPPT are connected together. If there is a voltage difference between the parallel strings such as different string lengths, current will flow between the parallel strings. Opening and closing the fuse holder in this instance is the same as opening and closing under load. Damage to equipment and /or injury to personnel may occur.

. 32.

1 ). Ensure that all fuse holders are open.

2). Connect the positive lead of the meter to the positive string cable of the string under test. Connect the negative lead of the meter to the negative string cable of the string under test.

~ ~

CanadianSolar 5. Commissioning

3). Measure the voltage present between the positive and negative wires of each string.

If the open circuit voltage of the string is near the maximum value accepted by the inverter, verify the string length. Low ambient temperatures cause an increase in the string voltage causing potential damage to the inverter.

4 ). Check the polarity of the string. All digital meters have a negative ("-")indicator that indicates when a voltage is negative; in this case a string connected in reverse polarity.

WARNING

Input voltages higher than the maximum value accepted by the inverter

(see "Specifications" in Section 9) may damage the inverter.

Although Canadian Solar inverters feature reverse polarity protection, prolonged connection in reverse polarity may damage these protection circuits and/or the inverter.

5.4.3.2 Leakage to ground

Measure leakage to ground to check for a DC ground fault.

5.4.3.2.1 Detection of leakage to ground

Canadian Solar inverters are transformer-less and do not have an array connection to ground.

Any measurement of a fixed voltage between ground and either the positive or negative string wiring indicates a leakage (ground fault) to ground and must be corrected prior to energizing the inverter or damage to the inverter may result.

To measure leakage to ground, perform the following steps:

1 ). Ensure that all fuse holders are open.

2). Ensure that neither negative nor positive DC conductors are connected to the ground strip.

3). Measure each string positive connection to ground.

4). Measure each string negative connection to ground.

5). Verify the voltage is "floating", not a consistent voltage to ground. Make sure you notice the units of the measurement. mV is not the same as V.

6). Do not close the fuse holder and connect the strings if a leakage to ground has been detected. Improper operation and damage to the inverter may result.

Once all DC tests have been completed, close the fuse holders.

CanadianSolar

5.4.4 AC configuration

Verify AC configuration.

5.4.4.1 Measure VAC and frequency

Measure VAC and verify voltage is within local grid standards.

1 ). Measure each phase to ground (L-G).

2). Measure phases to the other phases in pairs (L-L). PH A to PH B, PH B to PH C and

PH Cto PHA.

3). If the meter is equipped, measure the frequency of each phase to ground.

4 ). Ensure each measurement is within local grid standards and the inverter specifications as noted in Section 9 "Specifications".

5.4.4.2 Phase rotation test

A phase rotation test is recommended to ensure the phases have been connected in the appropriate order. Canadian Solar inverters do not require a specific phase rotation connection.

However, the local utility may require a specific phase rotation or a record of the phase configuration of the installation.

6. Normal operation

6.1 Start-up procedure

To start-up the inverter, it is mandatory that the steps below are followed in the exact order outlined.

1 ). Ensure the commissioning checks in Section 5 have been performed.

2). Switch theAC switch ON.

3). Switch the DC switch ON. If the PV array (DC) voltage is higher than the inverter's start-up voltage, the inverter will turn on. The red DC POWER LED and LCD will be continuously lit.

4 ). Canadian Solar inverters are powered from the DC side. When the inverter detects DC power that is within start-up and operating ranges, the inverter will turn on. After turnon, the inverter will check internal parameters, sense and monitor AC voltage, hertz rate and the stability of the supply grid. During this period, the green OPERATION LED will flash and the LCD screen will show INITIALIZING. This tells the operator that the inverter is preparing to generate AC power.

5). After the locally mandated delay (300 seconds for IEEE-1547 compliant inverters), the inverter will start generating AC power. The green OPERATION LED will light continuously and the LCD screen will show GENERATING.

CAUTION

The inverter's surface temperature can reach up to 75•c (167° F). To avoid risk of burns, do not touch the surface when the inverter is in the operational mode. Additionally, the inverter must be installed out of the reach of children.

6.2

Shutdown procedure

To stop the inverter, it is mandatory that the steps below are followed in the exact order outlined.

1 ). Switch AC switch OFF.

2). Wait approximately 30 seconds (during this time, theAC side capacitors are dissipating energy). If the inverter has DC voltage above the start-up threshold, the red POWER

LED will be lit. Switch the DC switch OFF.

CanadianSolar 7. Maintenance

Canadian Solar Three Phase Inverter does not require any regular maintenance. However, cleaning the dust on heat-sink will help the inverter to dissipate the heat and increase its life time. The dust can be removed with a soft brush.

CAUTION:

Do not touch the inverter's surface when it is operating. Some parts of the inverter may be hot and cause burns. Turn off the inverter (refer to Section

6.2) and wait for a cool-down period before before any maintenance or cleaning operation.

The LCD and the LED status indicator lights can be cleaned with a damp cloth if they are too dirty to be read.

NOTE:

Never use any solvents, abrasives or corrosive materials to clean the inverter.

7.1 Anti-PI D Function

CSI-125KTL-GS-E integrates optional Anti-PID module and it can recover the

PID effect during night thus protect the PV system from degradation.

CSI-125KTL-GS-E

Figure 7.1

The Anti-PID module repairs the PID effect of the PV model at night. When operating, the inverter LCD screen displays" PID-repairing" information, and the red light is on.

TheAnti-PID function is always ON whenAC is applied.

If maintenance is required and turn off the AC switch can disable the Anti-PID function.

WARNING:

The PID function is automatic. When the DC bus voltage is lower than 260Vdc, the PID module will start creating 650 Vdc between PV- and ground.

No need any control or settings
