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:After the PV inverter, how to achieve the same period before the network?
Grid simulator: analog power grid, normal and abnormal conditions, overvoltage, undervoltage, over frequency, under frequency, sudden power failure, etc.
Q:Photovoltaic grid-connected inverter without DC emc how will happen
Solar photovoltaic power generation technology is the use of solar cells, the photovoltaic effect of semiconductor materials, solar radiation can be directly converted into a new type of power generation system, solar energy is a radiant energy, solar power means --- to direct conversion of sunlight Into electricity,
Q:PV grid-connected inverter can directly load it?
Grid-connected inverter is like a car file, he first detects the grid waveform, can not detect not boot, and then the PV DC modulation and consistent with the grid waveform, and then hang up.
Q:Installation and maintenance of photovoltaic grid - connected inverter
only when the local power sector permission by the professional and technical personnel to complete all the electrical connection before the inverter can be connected.
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.
Grid-connected inverter is generally used with large-scale photovoltaic power plant system, a lot of parallel PV string is connected to the same set of inverter DC input, the general power of the use of three-phase IGBT power module, power
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 function of photovoltaic grid - connected inverter
Finally, a sinusoidal AC output for a grid-connected photovoltaic power generation system is generated by a low-pass filter.
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?
Grid-connected inverter will be directly sent to the power grid, so to track the frequency of the grid, phase, the equivalent of a current source. Of course, there are some inverters that have a low-pressure through the ability to do PQ adjustment.
