Modes of operation 
There are 3 different modes of operation. 
1. Normal mode: In this mode, the inverter works normally. Whenever the 
supplied power from PV panel is sufficient (voltage>150VDC), inverter 
converts power to the grid as generated by the PV panel. If the power is 
insufficient (voltage<120VDC), inverter enters a “waiting” state. Whilst 
“waiting” inverter uses just enough power from the PV panel monitor 
internal system status. In normal mode the green LED is on. 
2. Fault mode: The internal intelligent controller can continuously monitor 
and adjust the system status. If inverter finds any unexpected 
conditions such as grid problems or internal fail ure, it will display  the 
information on its LCD and light up the red “Fault” LED.
