With the development of the photovoltaic industry, the working efficiency of photovoltaic panels has become better. Inventec's newly developed photovoltaic water pump solution, GD100-PV, has been quietly launched and successfully applied throughout the world. This PV frequency converter has learned from previous generations of products and has improved with feedback from end-customers around the world. This article will introduce the GD100-PV series of photovoltaic pump inverter.
First, introduce
After collecting feedback from the solar market and end users, we have the following suggestions:
1. Reduce the use of photovoltaic panels
Because ordinary solar inverters require a high DC input voltage.
2. Support single-phase water pump
For civilian pumps, many motors are single-phase, and many PV pump inverters on the market do not support single-phase, only three-phase.
3. Support AC/PV channel input
At night, if there is no PV input energy, the pump will stop working. Some projects require the pump to remain in working condition.
4. Easy to debug
Previous generations of products need to modify some parameters to be suitable for different pumps, and the new inverter can automatically match the parameters to work.
5. Support remote control
The user can use the mobile phone application or web site to monitor the running status of the machine and control the system to start or stop working.
In order to meet the needs of end-users and solve the disadvantages of PV pump inverters on the market, Inventronics has developed a new product, GD100-PV, to meet the above requirements.
Second, the advantages of GD100-PV series photovoltaic inverter
1. It is applicable to single-phase or three-phase pumps and has a wide range of applications.
2. Built-in MPPT controller, excellent MPPT algorithm for a variety of solar panels.
3. IP54 control cabinet solution, this solution can be applied to the harsh outdoor environment, can be installed directly in the outdoors.
4. Support boost module less than 2.2KW to increase PV output voltage.
5. Support PV input and AC grid input, and can realize automatic switching function without manual intervention.
6. It has a water level control logic function to avoid the dry and dry running state and increase the full water level protection function.
7. Start flat and reduce the voltage spike on the motor.
8. The low start-up voltage and wide input voltage range provide more possibilities for accepting multiple PV string configurations and different types of PV modules.
9. Digital intelligent control can flexibly adjust and set the pump speed range. In addition to the soft start function, lightning protection, overvoltage, overcurrent, overload and other protection functions can also be provided.
10. Support GPRS module, people can use the website platform or mobile application operating system.
Third, photovoltaic
Photovoltaic photovoltaic (PVorphotovoltaic) is an abbreviation of photovoltaic power system. It is a new type of power generation system that utilizes the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. It has independent operation and grid connection. Run two ways. At the same time, solar photovoltaic power generation system classification, one is centralized, such as large-scale northwest ground photovoltaic power generation system; one is distributed (with> 6MW as the demarcation), such as industrial and commercial enterprises plant roof photovoltaic power generation system, residential roof photovoltaic power generation system.
Four, GD100-PV photovoltaic water pump inverter two solutions
For different power pumps, we offer two solutions.
For pumps with power less than 2.2 kW, when we configure the solar panels, the photovoltaic power is sufficient, but the photovoltaic output voltage is insufficient, so we need to purchase more solar panels to increase the photovoltaic voltage. The GD100-PV provides a boost module that supports low PV voltage input and high DC voltage output to reduce the number of PV panels used.
The automatic switching module can detect the output voltage of the voltmeter and send the voltage signal to the GD100-PV inverter. The inverter will control the contactor and turn on or off the AC input.
V. Conclusion
GD100-PV integrates many functions, such as reducing the PV input voltage, switching of DC power switch and AC power switch input channel, high protection level IP54, etc. After this solar inverter is set parameters for the first time, end users do not need to maintain.
After sunset, the light will be weak, and the GD100-PV can detect that the PV voltage is less than the set value. He will automatically switch the power input channel from PV to AC grid input. If only the PV channel can input voltage, then GD100-PV will sleep in low light and wake up automatically in the morning.
O Ring are installed in the groove, moderate compression section for type O Sealing Ring (circle). Because of its manufacturing cost is not high, convenient installation and therefore has been widely used in the sealing industry.
O-ring mainly used for fluid (such as: water, oil, air, chemical solvents, chemicals, etc.) and sealing the gap between a static long-term use temperature of -60 ℃ to 220 ℃.. Varies on material, the use of static pressure is less than 20MPa. Sometimes for dynamic, dynamic pressure when using less than 5MPa. And semiconductor vacuum seal.
An o-ring technically is also a gasket but it's shape and the material it is made from differs from most gaskets. The biggest difference between the two is o-rings are almost exclusively used for very high pressure applications such as hydraulics where a regular cork, paper or Rubber Gasket would fail.
