On grid solar pump inverter (0.5KW-55KW) 
10 years expert in solar products 
Competive price with good quality 

Product Description:

Solar water pumping system is constructed with solar panel array,solar pump inverter and AC water pump, DC current produced from solar panel,then delivered to solar pump inverter,and it will convert it into AC current to drive water pump,and will automatically regulate output frequency according to sun radiance intensity,maximally realize MPPT tracking function.

Product Features:

1. Adopting the proposed dynamic VI maximum power point tracking (MPPT) control method, with fast response, and reliable operation, achieves efficiency of 99%.

 

2.Designed with variable frequency driver, greatly improves efficiency.


3.Extremely high efficiency.


4.Digital mode control, with automatic operation and manual operation mode options.


5.Complete protection functions.


6.Adopts intelligent IPM module, with high reliability.


7.LCD display and operation panel, in real time presents operating data.


8.Optional for water level measurement and control circuit.


9.Applicable for general ACC pumps, like centrifugal pump, piston pump etc.

 

10.Independent intellectual property; Highly effective, the redundant reliability, exempts the maintenance and the long life.


11.The pumps are soft started, fully protected.


12.No batteries are used. So better Sunlight, more water.

Q:Grid-connected inverter is generally divided into photovoltaic power generation grid-connected inverter, wind power grid-connected inverter, power equipment and grid-connected inverter and other power generation equipment power generation inverter.
The grid inverter is a current source, the output voltage is basically the grid voltage, may be slightly raised.
Q:What is the difference between a PV inverter and a solar inverter?
Instability, the wind speed and the equipment itself will directly affect the generator rotation, so the voltage and current fluctuations, frequency instability, in short, is the power quality is poor) Therefore, through the inverter after the first rectification inverter to improve the quality of power
Q:Is the PV inverter a current source or a voltage source?
According to the waveform modulation method can be divided into square wave inverter, stepped wave inverter, sine wave inverter and modular three-phase inverter.
Q:The working principle of photovoltaic grid - connected inverter
Full-bridge inverter circuit to overcome the shortcomings of the push-pull circuit, the power transistor to adjust the output pulse width, the output AC voltage RMS that changes. Since the circuit has a freewheeling circuit, even if the inductive load, the output voltage waveform will not be distorted. The disadvantage of this circuit is that the upper and lower arms of the power transistor are not common, so you must use a special drive circuit or use isolated power supply. In addition, in order to prevent the upper and lower arm co-conduction, must be designed to turn off after the conduction circuit, that must be set dead time, the circuit structure is more complex.
Q:What is the difference between a grid-connected inverter and an off-grid inverter? What are the advantages of a hybrid inverter?
Offline generally need energy storage, not to send energy to the Internet. Grid has no right to interfere.
Q:PV grid-connected inverter and independent inverter in the control of what is the difference
The independent inverter in the output voltage phase amplitude of the frequency control is initially set good. Independent inverter, you should refer to off-grid inverter, do not need to consider the grid situation.
Q:The function of photovoltaic grid - connected inverter
After some additional voltage buffering, the left side of the bridge is usually 18 ~ 20khz switching frequency, the dc voltage is converted to ac voltage.
Q:Installation and maintenance of photovoltaic grid - connected inverter
Before the installation should first check whether the inverter in the transport process for damage. When selecting the installation site, there should be no interference with any other power electronic equipment in the surrounding area.
Q:In a photovoltaic grid-connected project, the role of the inverter is to convert the voltage into AC 220V or 380V for the grid, since the transformer will raise the voltage again
Self-use, do you mean off-grid system? Or else? Europe and Sweden side of the grid project electricity situation is also self-use? If not for their own use or spontaneous use is not used up, sent to other places electricity, you need a transformer?
Q:Generally a large grid-connected photovoltaic power plant will have several inverters
, This method is simple to design, easy maintenance, but also for the power grid harmonics smaller, good power quality!
