Note: If the bus voltage is lower than the
undervoltage point or the PV voltage is
lower than 70V, it will report the weak
light alarm without any delay time.
If P15.32=0, the system will switch to the
power frequency input when the light is
weak.

Delay time of wake-up at weak light
If the weak light alarm is reported, after
the delay time of wake-up, the alarm will
be cleared and it will run again.

When P15.32=0, if the PV voltage is
higher than P15.34, after the delay time,
it will switch to PV input mode.
