Product Application

Q&A

1. Does the product need to set a lot of parameters?

No, it doesn't. The inverter has a self-adaptive and self-learning function. It is automatic start and stop, you can press Run key to start, or you just wait for 600S then it will automatically start

2. Could it replace my previous PV pumping inverter?
Yes, of course. Selecting inverter model according to the rated voltage, current and power of the water pump. A bit more is better. Then take off the old one and put ours on, the system will work.

3. 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 need, we will provide technical support online.

4. How to make the water pump system work without sunshine?

Usually, solar PV water pump system can meet the needs of pumping water.
If there is no sunshine, the system will not work. But out inverter could also support AC input. So, connect the power grid or diesel power generation to the inverter, the pumping system will work. If necessary, keep switch and interface locations during the system design time.

5. How to use terminal control with external switch to run and stop solar pump inverter ?
(Terminal control): 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

6. How to use a float in the water tank to stop the pump if the tank is full?
Use float switch to short DI 1 and com.

7. Use level probe in the well for protection against dry running
Set P24.12=1 and set P24.13 and P24.14 and P23.21

8. How to set minimum frequency 25hz and maximum 50HZ?
Set P47.05=25HZ and 47.06 to some time and 47.07 to some time

9. If pump is 60HZ frequency, how to set max frequency?
Notice: If your motor rated frequency is 60HZ you should set P01.06=P01.08=P11.05=60HZ.

10. How to achieve Automatic start after stop?
Our solar pump inverter is automatic start and stop with our special software
