The inverter is equipped with RS232 and USB ports and it is
also equipped with a slot for alternative communication
interfaces in order to communicate with a PC with
corresponding software. This intelligent slot is suitable to install
an SNMP card or Modbus card. Follow the procedure below to
connect communication wiring and install the software.
Install monitoring software on your computer. Detailed
information is listed in the next chapter. After software is
installed, you may initiate the monitoring software and extract
data through the communication port.
NOTE: If using the modbus card as your communication
interface, install the separately bundled software. Consult
with your local dealer for more information.
Step 1:
Check the following requirements before
commissioning:
Ensure the inverter is firmly mounted.
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 the same as 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.
Ensure that the AC circuit breaker (only applied when the
utility is required), batter circuit breaker and DC circuit
breakers are installed correctly.
Step 2:
Switch on the battery circuit breaker and then connect
the PV DC breaker. After that, if there is utility connection,
switch on the AC circuit breaker. The inverter is now turned on.
There is however no output generation for loads. Then:
If LCD lights up to display the current inverter status,
commissioning has been successful. After pressing “ON”
button for 1 second when the utility is detected, the inverter
will start to supply power to the loads. If no utility exists,
press the “ON” button for 3 seconds. The inverter will start
to supply power to the loads.
If the red LED lights up, or warning/fault indicator appears
on LCD, an error has occurred. Please inform your installer.
Step 3:
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.
