Commissioning
Step 1: Check the following requirements before commissioning:
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.
Check if connection of AC cable to grid (utility) is correct if the utility is required.
Full connection to PV modules.
AC circuit breaker (only applied when the utility is required), batter circuit breaker,
and DC circuit breaker are installed correctly.
Step 2: Switch on the battery circuit breaker and then switch on PV DC breaker. After
that, if there is utility connection, please switch on the AC circuit breaker. At this moment,
the inverter is turned on already. However, there is no output generation for loads. Then:
If LCD lights up to display the current inverter status, commissioning has been
successfully. After pressing “ON” button for 1 second when the utility is detected,
this inverter will start to supply power to the loads. If no utility exists, simply press
“ON” button for 3 seconds. Then, this inverter will start to supply power to the
loads.
If a warning/fault indicator appears in LCD, an error has occurred to this inverter.
Please inform your installer.
Step 3: Please insert CD into your computer and install monitoring software in 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 shortcut icon
located in the system tray, near the clock.
NOTE:
If using modbus card as communication interface, please install bundled
software. Check local dealer for the details.
