dormant. If the state is not continuous, the delay
counting will be cleared automatically.
Note: If the PV voltage is lower than software
undervoltage point, it will report directly and no
need to wait for the set time.
If P15.29=0, the system will switch to the power
frequency input when the light is weak.

0.0–3600.0s
Delay time of wake-up at weak light
During the weak light warning, if the PV voltage is
higher than the starting voltage, after the delay
time, the warning will be cleared and it will run
again.
When P15.29=0, if the PV voltage is higher than
P15.31, after the delay time, it will switch to solar
input mode.

tracked voltage
Track in the range of P15.23–P15.24. P15.24
needs to be bigger than P15.23. The less the
difference, the faster the tracking is. But the Max.
voltage needs to be in the range. P15.23 and
P15.24 can be adjusted according to site operation.
The default value depends on model.
For models of 220V:
