Step 5: Insert the sealing caps provided into unused DC connectors on the inverter.
7. Commissioning
Step 1: Check the following requirements before commissioning:

Ensure the inverter is firmed secured

Check if the open circuit DC voltage of PV module meets requirement (Refer to Section
6)

Check if the open circuit utility voltage of the utility is at approximately same to the
nominal expected value from local utility company.

Correct connection to grid

Full connection to PV modules

Unused DC input connectors are sealed with supplied sealing plugs.

AC circuit breaker and DC circuit breaker are installed correctly.
Step 2: Switch on the AC & DC circuit breakers. All three LEDs will light up. Then:

If green LED lights up, commissioning has been successfully.

Or, if yellow LED lights up, there is insufficient radiation and the inverter is in standby
mode. Wait for sufficient radiation.
CAUTION: Never disconnect running inverter from AC Grid. If it’s necessary to turn off the
inverter, disconnect the AC breaker first and then DC breaker next.
CAUTION: Never directly touch terminals of the inverter. It will cause lethal electric shock.
