Starting
The inverter has sufficient DC voltage to initialize its internal systems, but not enough to
begin normal operation. Typically, the calibration lasts less than 10 seconds and then
the inverter resumes normal operation. DC voltage must remain greater than the PV Start
Voltage setting for the period of the T-Start parameter setting. (See Section 8) The
inverter will also show this status if it has been manually set to STOP mode.
Waiting
The inverter has determined that there is enough DC voltage to operate and is checking
the condition of the grid prior to connecting.
Note: If the inverter fails to connect to the utility grid 3 times
in a row, it will wait 10 minutes before the next attempt.
In case of a grid failure, the Sunny Boy will wait 5 minutes
before it tries to reconnect to the grid.
