Commissioning
Step 1: Check the following requirements before commissioning:
•
Ensure the inverter is firmly secured
•
Check if the open circuit DC voltage of PV modules meet requirement (Refer to
Section 6)
•
Check if the utility voltage is approximately in line with the nominal expected value
from utility.
•
Check if connection of AC cable to grid (utility) is correct, if applicable.
•
Complete connection to all PV modules.
•
AC input circuit breaker (only applicable if utility is used), battery circuit breaker/fuse,
and DC circuit breaker/fuse from array are installed correctly.
Step 2: Switch on the battery circuit breaker/fuse and then switch on PV DC breaker.
After that, if there is utility connection, switch on the AC input circuit breaker. At this
point, the inverter is active. However, there is no output generation for loads.
Then:
•
If LCD lights up to display the current inverter status, commissioning has been
carried out
successfully. After pressing “ON” button for 1 second w
hen the utility is
detected, the inverter will start to supply power to the loads. Without utility, simply
press “ON” button for 3 seconds
and the inverter will start to supply power to the
loads.
•
If a warning/fault indicator appears on the LCD screen, an error has occurred. Please
inform your installer.
Step 3: Insert CD into your computer and install monitoring software on your PC. Follow
below steps to install software.
1. Follow the on-screen instructions to install the software.
2. When your computer restarts, the monitoring software will appear as a shortcut icon
located in the system tray, near the clock.
NOTE:
If using Modbus card as communication interface, please install bundled
software. Contact your distributor for details.
