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:Three-phase photovoltaic inverter grid, the use of phase-locked loop is what?
Grid-connected inverter can be operated locally through the LCD screen, or through remote monitoring with dedicated monitoring software.
Q:What are the methods of photovoltaic grid-connected inverter control
The square wave output of the inverter using pulse width modulation integrated circuits, such as SG3525, TL494 and so on. Practice has proved that the use of SG3525 integrated circuits, and the use of power FET as a switching power components, to achieve high performance of the inverter, because the SG3525 has a direct drive power FET capability and has an internal reference source and operational amplifiers and Undervoltage protection, so its peripheral circuit is very simple.
Q:What is the difference between a PV grid-connected inverter and an off-grid inverter?
Off-grid inverter is equivalent to their own to establish an independent small power grid, mainly to control their own voltage, is a voltage source.
Q:PV grid-connected inverter and independent inverter in the control of what is the difference
PV grid-connected inverter in the grid before the inverter needs to determine the phase voltage phase frequency, the first phase-locked, in the grid and power generation.
Q:Photovoltaic grid-connected inverter problem
The first zero line is the AC output. Any AC output of the inverter will have zero line, whether it is isolated or non-isolated. Isolation is the safety of high voltage inverters and regulators. 50KW above the inverter almost with the transformer.
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:Photovoltaic grid-connected inverter without DC emc how will happen
When solar or other light illuminates the PN junction of the semiconductor, a voltage (called a photogenerated voltage) occurs on both sides of the PN junction. This phenomenon is the famous photovoltaic effect.
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: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: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!
