2.3 Notice For Use
The inverter has been constructed according to the applicable safety and technical
guidelines. Use the inverter in installations that meet the following specifications ONLY:
1. Permanent installation is required.
2. The electrical installation must meet all the applicable regulations and standards.
3. The inverter must be installed according to the instructions stated in this manual.
4. The inverter must be installed according to the correct technical specifications.
5. To startup the inverter, the Grid Supply Main Switch (AC) must be switched on, before
the solar panel's DC isolator shall be switched on. To stop the inverter, the Grid Supply
Main Switch (AC) must be switched off before the solar panel's DC isolator shall be
switched off.
.6.
CAUTION:
The PV array (Solar panels) supplies a DC voltage when they are exposed to
sunlight.
CAUTION:
Risk of electric shock from energy stored in capacitors of the Inverter. Do not
remove cover for 5 minutes after disconnecting all power sources(service technician
only). Warranty may be voided if the cover is removed without unauthorized .
CAUTION:
The surface temperature of the inverter can reach up to 75℃ (167 F).
To avoid risk of burns, do not touch the surface of the inverter while it’s operating.
Inverter must be installed out of the reach of children.
CAUTION:
Risk of electric shock. Do not remove cover. There is no user serviceable
parts inside. Refer servicing to qualified and accredited service technicians.
PV module used with inverter must have an IEC 61730 Class A rating.
WARNING:
To reduce the risk of fire, over-current protective devices (OCPD) are
required for circuits connected to the Inverter.
The DC OCPD shall be installed per local requirements. All photovoltaic source
and output circuit conductors shall have disconnects that comply with the NEC
Article 690, Part II. All Canadian Solar single phase inverters feature an
integrated DC switch.

There are four keys in the front panel of the Inverter(from left to right):
ESC, UP, DOWN and ENTER keys. The keypad is used for:
Scrolling through the displayed options (the UP and DOWN keys);
Access to modify the adjustable settings (the ESC and ENTER keys).
3. Overview
The two-line Liquid Crystal Display (LCD) is located on the front panel of the Inverter,
which shows the following information:
Inverter operation status and data;
Service messages for operator;
Alarm messages and fault indications.
.8.
Figure 4.1 Recommended Installation locations
To select a location for the inverter, the following criteria should be considered:
Do not install in small closed spaces where air can not circulate freely. To avoid
overheating, always make sure the flow of air around the inverter is not blocked.
To avoid over heating ambient air temperature must be considered when choosing the
inverter installation location. Canadian Solar recommends using a sun shade minimizing
direct sunlight when the ambient air temperature around the unit exceeds 104°F/40°C.
Exposure to direct sunlight will increase the operational temperature of the inverter and
may cause output power limiting. Canadian Solar recommends inverter installed to avoid
direct sunlight or raining.

When 1 or more inverters are installed in one location, a minimum 12inchs clearance
should be kept between each inverter or other object. The bottom of the inverter should
be 20inchs clearance to the ground.
Visibility of the LED status indicator lights and the LCD located at the front panel of
the inverter should be considered.
Adequate ventilation must be provided if the inverter is to be installed in a confined space.
NOTE:
Nothing should be stored on or placed against the inverter.

The inverter has intergrated export limitation functionality.
To use this function a power meter or a CT must be installed if use the power meter it should , , ,
be installed in the load side or in the grid side Because the meter used in the single-phase ,
inverter is divided into two types: single-direction meter, and dual-direction meter.Therefore,
the wiring method is divided into two cases.The dual-direction meter corresponds to the meter
in grid connection mode; the single-direction meter corresponds to the meter in load connection
mode.see Figure 4.22 and 4.23. After the inverter power on please set the corresponding ,
configuration as sections 6.5.11.1.2 and 6.5.11.1.3.

4. Installation
.23..22.
5. Start & Stop
5.1 Start the Inverter
To start up the Inverter, it is important that the following steps are strictly followed:
1. Switch the grid supply main Switch (AC) ON first.
2. Switch the DC switch ON. If the voltage of PV arrays are higher than start up voltage,
the inverter will turn on. The red LED power will light.
3. When both the DC and the AC sides supply to the inverter, it will be ready to generate
power. Initially, the inverter will check both its internal parameters and the parameters
of the AC grid, to ensure that they are within the acceptable limits. At the same time,
the green LED will flash and the LCD displays the information of INITIALIZING.
4. After 30-300 seconds (depending on local requirement), the inverter will start to
generate power. The green LED will be on continually and the LCD displays
GENERATING.
WARNING:
Do not touch the surface when the inverter is operating. It may be
hot and cause burns.
5.2 Stop the Inverter
To stop the Inverter, the following steps must be strictly followed:
1. Switch the Supply Main Switch (AC) OFF.
2. Wait 30 seconds. Switch the DC Switch OFF. All the LEDs of the inverter will be off in one
minute.
5.1.1 Inverter working status
Generating:Inverter is working normally
LimByTemp: Inverter power limited by over ambient temperature.
LimByFreq: Inverter power limited by over grid frequency
LimByVg: Inverter power limited by over grid voltage

When inverter working normally,there would be 5 status :
Logic interface is required by G98 and G99 standard that can be operated by a simple switch
or contactor. When the switch is closed the inverter can operated normally. When the switch
is opened, the inverter will reduce it’s output power to zero within 5s.
Pin5 and Pin6 of R J45 terminal is used for the logic interface connection.
