P15.27–6553.5V
During the max. power tracking, the upper
limit of the solar panel reference voltage will
not exceed the value of P15.31. The factory
value
value depends on the model. By default, the
value for the -4 models is 750V and the
value for other models is 400V.
0: Automatic switching mode
1: Power frequency input mode
2: PV input mode
If P15.32 is set to 0, the system switches
between PV input and power frequency
power input according to the detected PV voltage
and switching threshold.
input If P15.32 is set to 1, the system forcibly
switches to power frequency input;
If P15.32 is set to 2, the system forcibly
switches to PV input.
Note: P15.32 is invalid when terminal input
function 42 is valid.
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.
power
For inverters without boost modules, the
switching voltage is determined by the
input
external voltage detection circuit.
For inverters with boost modules, the
switching voltage is 70V.
P15.33–400.0V
If PV voltage is greater than the threshold,
the system can switch to PV input through
relay output with the weak-light wake-up
delay P15.24. To avoid frequent switching,
P15.34 shall be greater than P15.33. When
P15.34 is set to 0.0, it is invalid.
The default value depends on model.
