P15.25
Initial

0.0 – 2000.0V
●
P15.26
Mini voltage
reference of
Max. power
tracking
0.0 – P15.27
Valid in MPPT Max. tracking voltage, the Mini. tracked voltage
Track in the range of P15.26
– P15.27. P15.27 needs to be bigger than P15.26. The
less the difference, the faster the tracking But the Max. voltage needs to be in
the range. P15.26 and P15.27 can be adjusted according to site operation.
The default value depends on model.
For models of 220V:
0.75kW: 80.0V
1.5kW, 2.2kW and 4kW: 100.0V
For models of 380V:
2.2kW – 5.5kW: 220.0V

The default value depends on model.
For models of 220V:
0.75kW: 80.0V

P15.28
Adjustment of
initial reference
voltage
0.0 – 200.0V
MPPT begins to change from the reference voltage
Initial reference voltige =PV voltage-P15.28
For models of 220V, the default value is 5.0V.
For models of 380V, the default value is 10.0V.

P15.29
Upper and lower
limit time of
VMPPT
0.0 – 10.0s
When P15.29 is set to 0.0, the automatic adjustment is invalid.
If it is not 0.0, the upper and lower limit of Vmppt will be adjusted
automatically after the time set by P15.26. The medium value is the current
bus voltage and the limit is P15.30.
Maximum / Minimum reference voltage=Current bus voltge±P15.30 and it will
update to P15.26 and P15.27 at the same time

P15.31
Maximum value
of VMPPT
P15.27 – 6553.5V
The upper limit cannot exceed the P15.31 when VMPPT is the maximum value.
The default value depends on model.
For models of 380V, the default value is 750.0V.
and for other models, the default value is 400.0V.

P15.32
PV input and
power frequency
input selection
0: Automatic input
1: Forced power frequency input
2: Forced PV input
If the value is 0, the system will switch between PV and power frequency
according to the detected PV voltage and threshold.
If the value is 1, the system will force to switch to power frequency input.
If the value is 2, the system will force to switch to PV input.
Note: When the terminal input 44 is valid, the function code will be invalid.

P15.33
Threshold
setting for
switching to
power frequency
0.0V – P15.34
If the PV voltage is lower than the threshold or the light is weak, it can be
switched to power frequency input through relay output. (Note: The minimum
operation voltage of the system is 60V.)
If the value is 0, the function is disabled.
The default value depends on model.
For models of 220V:
0.75kW: 60.0V
1.5kW, 2.2kW and 4kW: 80.0V
For models of 380V:
2.2kW – 5.5kW: 180.0V
