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: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:After the PV inverter, how to achieve the same period before the network?
It can automatically detect the generator and the grid frequency and voltage, in the frequency, voltage, phase are in line with the requirements of the grid to set the time before the release of the closing signal, so that it can be safely and securely connected.
Q:Generally a large grid-connected photovoltaic power plant will have several inverters
The use of a high-power grid-connected inverter into the grid, the need for line design is relatively simple, because the DC and AC lines are separated, the use of convergence box to summarize, DC bus and then into the grid inverter
Q:What are the methods of photovoltaic grid-connected inverter control
and can set the dead time between the upper and lower arms, the use of INTEL 80C196MC to achieve sine wave output circuit, 80C196MC to complete the sine wave signal, AC output voltage, to achieve regulation. Circuit output generally use LC circuit filter high frequency wave, get pure sine wave.
Q:The working principle of photovoltaic grid - connected inverter
In the small-capacity inverter generally push-pull inverter circuit, full-bridge inverter circuit and high-frequency step-up inverter circuit three, push-pull circuit, the step-up transformer neutral plug connected to the positive power supply, two power Alternating current, the output to get AC power, due to the power transistor to ground, drive and control circuit is simple, and because the transformer has a certain leakage inductance, can limit the short circuit current, thus improving the reliability of the circuit. The disadvantage is the low utilization of the transformer, driving the emotional load is poor.
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:Is the grid side of the grid and the inverter?
Grid-type system power transmission sequence: photovoltaic panels> relays> inverters> relays> electricity load + power grid (both in parallel).
Q:The function of photovoltaic grid - connected inverter
In general, single-phase h-bridge is a common configuration of dc / ac-level, but can also be used in three-phase and other configurations.
Q:Is the PV inverter a current source or a voltage source?
Inverter is a kind of semiconductor device composed of power adjustment device, mainly used for DC power into AC power.
Q:Installation and maintenance of photovoltaic grid - connected inverter
Before making an electrical connection, be sure to use the opaque material to cover or disconnect the PV panel. Exposure to sunlight, photovoltaic arrays will produce dangerous voltages. All installation operations must be done only by qualified technicians.
