7.2 Operating Mode

7.2.1 Waiting Mode

At this mode, inverter will check the system parameter. If the system is normal and PV voltage is more than 250VDC,
inverter will try to connect to the grid.
7.2.2 Operating Mode
In this mode, the inverter works normally, the leaf of the indication window turns green, and the LED display shows the
active power and apparent power.
When the DC voltage is more than 250V DC, inverter will send the AC current converted from PV module DC to the grid.
When the DC voltage is lower than 250VDC, inverter will enter into ―waiting‖ and try to connect to the grid, at this status,
inverter consume very small power to check the internal system status.
Note: only when the PV modules supply enough power(voltage＞200VDC) then the inverter will start automatically.

7.2.3 Failure Mode

The intelligent control system of the inverter constantly monitors and adjusts the state of the system. When the inverter
detects any fault, the leaf of the indication window is steady red or flashing red, and the LED display shows the fault
message.
Note: please refer to section 9.2 to check the fault message and take corrective measures.
