0.0V~P15.34
If PV voltage is lower than the threshold
or the light is weak, it can switch to
power frequency input through the relay
output.
If the value is 0, it is invalid.
For inverters without the boost module,
the switching point voltage is determined
by the external voltage detection circuit.
For inverters with the boost module, the
switching point voltage is 70V.
P15.33~400.0V
If PV voltage is greater than the
threshold, it can switch to PV input
through the relay output after the time set
by P15.24. To prevent frequent
switching, this threshold must be greater
than P15.33.
If the value is 0.0, it is invalid.
The default value depends on model.
The pump flow is
at the rated pump frequency and rated
lift. Unit: cubic meter/hour.
The pump lift is
the rated frequency and rated current.
Unit: meter
