5.6. Post installation checklist
Before connecting the PV modules to make sure that the polarity of the DC terminals of each link is
correct.
The incorrect connection may damage this equipment
permanently
1. High voltages exist when PV-Panel is exposed to sufficient irradiation. Exposed terminals of PV-Panel are
under tension, and can cause electric shock. Avoid making physical contact with those parts of the
device.
2.
After PV-Panel is connected to the PV inverter, the output voltage is greater than 300VDC and when the
AC grid is not connected to the Inverter, the Data Logger LCD displays the following:
Pac:0W
Temperature:26.8°C
Iac:0.0/0.0/0.0A
Vac:0.0/0.0/0.0V
Status:Fault
No Utility

3. Check the connection between PV inverter and the AC Connection System, and then check the
connection between the Public Utility and the AC Junction Unit. Close the AC breaker or fuse in the unit.
4.
Under normal operation, the Data Logger LCD shows the following as an example:
Pac:7494W
Temperature:26.8°C
Iac:10.5/11.2/10.7A
Vac:219.4/219.3/219.3V
Status:Normal
21.04.12 15:01
5. When the display is green, the Inverter is feeding power to the grid. Under such condition, you have
installed the Inverter successfully.
