Chapter 4 Installation and commissioning
19
1. Wiring in accordance with the wiring diagram and closing the switch Q1 after checking the
corrected wiring.
Note: the AC power and photovoltaic power can not simultaneously supply power to the
inverter, can only choose one from them.
2. y0.00=1(Factory Reset); Set b0.00 ~ b0.05 motor parameters according to the motor
nameplate
3. Set F0.03 = 8 (PV settings); E0.00 = 2 (MPPT mode);
4. Water amount test. After setting the parameters, press the RUN key, observe the operating
frequency and the water situation. In normal light conditions, when the running frequency is high
but the water is running less, it indicates motor reversal phenomenon and need to modify the F0.24
= 1, then observe the water amount.
5. Set point of failure and fault reset time delay settings. If customer needs to use the weak
light, full of water, under-load, can set detection point, the number of automatic reset and automatic
reset time are set as per customer’s request.
Take 380V voltage rating as an example:
There are two modes of inverter sleep, one for detecting bus voltage, the other is detecting
frequency value.
Bus voltage sleep mode:
(1) When the sunlight is weak, the Solar inverter turn into hibernation. When the sunlight is
strong, the Solar inverter automatically wakes. Set E0.07 ~ E0.08 voltage detection value.
Parameter settings: F0.03 = 8 (PV settings);E0.00 = 2 (MPPT mode);E0.07 = 530 (PV wake
voltage);E0.08 = 400 (PV dormant voltage);
If the Solar inverter operate normally and when the sunlight is weak, the bus voltage becomes
less than 400V, then the Solar inverter enters into hibernation. When the sunlight is strong, the bus
voltage is greater than 530V, the Solar inverter will automatically start running. Set the voltage of
PV wake and sleep according to the situation. The two values can not be set at too close, if setting
too close, the Solar inverter may start and stop frequently.
Detect frequency sleep mode:
Parameter setting: F6.13 = 1 (sleep mode on); E0.03 = 30s (wake-up time after sleep);E0.09 =
20Hz (sleep frequency);E0.11 = 60s (sleep waiting time)
Assuming the inverter is running, the frequency is below 20Hz, run for 60s below 20Hz, the
inverter will stop and enter the sleep mode, wait for 60seconds inverter to restart after running.
(2) Water level detection mode 1- Switch detection.
When using the switch detection, the test line lead to DI terminal, Then the corresponding
terminal is set to 8. If used as a feedback input signal DI2, DI2 = 8. When filled with water, DI2
signal is active, the Solar inverter will free stop. When the water level is below the detection value,
the corresponding terminal is set to 1. (As with DI1 as the start signal, DI1=1), Solar inverter starts
automatically.

Connect the test line according to the figure.
Set parameters: F0.03 = 8 (PV settings);
F0.11 = 4 (keyboard + Terminal + communication);
F1.00 = 1 (forward run);
F1.01 = 8 (freewheel);
F1.10 = 2 (three-wire mode 1)
