P15.34
Threshold
setting for
switching to PV
input
P15.33–400V
If PV voltage is higher than the threshold, after the delay time of P15.24, it can
be switched to PV input through relay output. In order to avoid repeated
switching, the threshold needs to be higher than the threshold of P15.33.
If the value is 0.0, the function is disabled.
The default value depends on model.
For models of 220V:
0.75kW: 100.0V
1.5kW, 2.2kW and 4kW: 120.0V
For models of 380V:
2.2kW–5.5kW: 240.0V

Voltage setting
at PV
undervoltage
point
When the PV voltage is less than the preset voltage, the system reports the PV
undervoltage (UV) fault.
The default value depends on the model.
Setting range: 0.0–400.0
