6. Start and Shutdown

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 the AC 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 turn-
on, 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℃ (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, the AC 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.
3). Confirm all LED's switch OFF (~one (1) minute).
CAUTION
Although the inverter DC disconnect switch is in the OFF position and all
the LED's are OFF, operators must wait five (5) minutes after the DC power
source has been disconnected before opening the inverter cabinet. DC
side capacitors can take up to five (5) minutes to dissipate all stored energy.
