Noted: We suggest solar panel power should be 1.3-1.4 times higher
than solar pump power ,
And solar pump inverter power should be higher level than solar
pump.
When solar pump distance to inverter higher than 100m,
It should be equipped with Output reactor or higher level power
inverter.
For Solar panel,total VOC less than Maximum DC voltage of inverter
and Solar panel vmp is recommend
530V for 380V pump and 305V for 220V pump.
Advantages:
1, Suitable for single phase pump, three phase pump. Permanent magnet synchronous pump
2, Support PV input and AC input at same time, make system work 24
hours.
3, Built-in MPPT technology with up to 99.9% efficiency.
4, With water level detection function, automatically regulate the
pump flow to prevent dryrunning
5, Water full protection function, when the water is full, inverter
will stop.
6, Support optional LCD keypad, you can know every parameter's
meansing on display,
and you can monitor any 5 group parmaters situation.
7, Support optional GPRS module, you can remotely monitor the
system situation.
1. How to achieve Automatic start after stop?
If it is controlled by keyboard no need to set any parameter. If
you want to control by external switch
As the default control mode is keypad control, First set P00.06=1
and use a wire or switch to connect com
and DI1,When the switch is closed, the drive run, when the switch is open,
the drive stop
2. How to design solar PV water pump system?
Key point: the rated VOC and VMP and power of the PV Array need to
match the input range of
the inverter. If needed, we will provide technical support online.
3. How to use a float in the water tank to stop the pump if the
tank is full?
If your float signal is digital signal Use float switch to short DI
3 and com ,see diagram 1.3
4. How to set minimum frequency ( for example) 30hz and maximum 50HZ
Set P47.05=30HZ and 47.06 to some time and 47.07 to some time.
Please refer to details of P47.05-47.07
5. If pump is 60HZ frequency, how to set max frequency?
Notice: If your motor rated frequency is 60HZ First solution for
you, P01.06=P01.08=P11.05=60HZ.
Quick setting and easier way: you should set P00.11=02 If your
motor is three phase; if your motor is single
phase with capacitor ,set P00.11=22;If your motor is single phase
without capacitor ,set P00.11=32
