y0.24
Water level direction
detection
0: Positive direction
，
higher
detection value higher water
level
Default: 1
1: Negative position
，
higher
detection value lower water
level
To set the relationship between hydraulic probe detected signal and water level
0: Positive direction, higher the detection value, higher is the water level
1: Negative position, higher the detection value, lower is the water level
y0.25
Weak light voltage
230V
～
MPPT minimum voltage
Default: 230V
For inverters with 400V, range: 230V
～
MPPT minimum voltage Default Value:230V
For inverters with 220V, range: 80V
～
MPPT minimum voltage Default Value:80V
When bus voltage is lower than the value of weak light voltage, inverter will soon enter the state of
weak light.
y0.26
Frequency given mode
0: Maximum frequency
1: Master frequency given
mode
Default: 0
0: Maximum frequency
Given frequency is the maximum frequency adjusted by MPPT function
1: Master frequency given mode
In frequency range adjusted by MPPT function, given frequency is adjusted by b0.01
y0.27
Power automatic switch
function
0:disable
1:Enable
Default: 0
y0.28
Time of automatic switch to
solar power
1
～
600Min
Default :60Min
y0.29
Automatic switch delay
0.1
～
10.0s
Default :3.0s
y0.30
Current power source in
automatic switch function
0: Grid power
1: Solar power
Default : 0
When y0.27=1 power automatic switch function is enabled i.e. grid power and solar power will be
switched automatically in the system. When system works with grid power, MPPT function is invalid
and the speed is adjusted by frequency given mode. When running time is over the set time of y0.28,
system will stop, switch to solar power and then restart. When system works with solar power, MPPT
function is valid. When system is under weak light, system will stop and switch to grid power then
restart. In every automatic switch, system will stop during the time setting as per y0.29 for the switch.
y0.30 shows current power source under automatic switch. Wiring diagram for the system has
been shown below:
