When BIT A0-00 is set to 0, follow the voltage
to control the water pump.
The higher the value is, the faster the search
speed is. When the parameter is set too large,
it is easy to cause vibration near the maximum

By setting local parameters to prevent: when
it is cloudy or in the evening(morning), the
output voltage of the solar panel is very low,
so the normal MPPT tracking method will make
the DC bus voltage too low, which may cause
the system under voltage shutdown.

This function can realize sleep and wake-up
functions. After the start command is issued,
if it is in sleep state, when the set
frequency exceeds A0-18 (wake-up voltage)
and the duration exceeds A0-19 (wake-up delay
time), the system will wake up and run. When
the system is
, if the set frequency
running
is less than A0-16 (sleep frequency), the
system will enter the sleep state (shutdown)
if the duration exceeds A0-17 (sleep delay
time). If set to A0-16 (sleep frequency)
and A0-18 (wake-up voltage) to 0, the sleep
and wake-up functions will be invalid.
