FAQ:
Q:How the output voltage of the PV inverter and the grid-connected voltage are determined
Inverter is the DC power (battery, battery) into alternating current (usually 220V, 50Hz sine wave). It consists of inverter bridge, control logic and filter circuit. Widely used in air conditioning, home theater, electric wheel, power tools, sewing machines, DVD, VCD, computer, TV, washing machine, range hood, refrigerator, video recorders, massage, fan, lighting and so on. In foreign countries
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: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:After the PV inverter, how to achieve the same period before the network?
Solar panel simulator: with MPPT function, simulated morning, noon, afternoon, evening, rainy weather, solar panels produced under different conditions in different voltages.
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: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:What is the difference between low voltage grid connection and medium voltage grid connection?
For photovoltaic power plants when the power system accidents or disturbances caused by photovoltaic power plant grid voltage drop, in a certain voltage drop range and time interval, the photovoltaic power plant can ensure that non-off-line continuous operation.
Q:Is the grid side of the grid and the inverter?
The grid load side of the grid is the grid. The inverter is an important part of the PV grid-connected system and can not be regarded as an external load. Photovoltaic power generation system is included in both grid and off-grid.
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: 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: How do you calculate the power output of a solar inverter?
- To calculate the power output of a solar inverter, you need to multiply the input voltage by the input current. This will give you the input power. Then, multiply the efficiency of the inverter by the input power to get the output power.
- 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: How does a microinverter differ from a string inverter?
- A microinverter differs from a string inverter in that it is a small, individual inverter that is connected to each solar panel in a system, whereas a string inverter is a larger inverter that is connected to multiple panels in a series (string). This means that each panel with a microinverter can operate independently, optimizing the power output of each panel, while a string inverter operates based on the performance of the entire string of panels. Microinverters also allow for easier monitoring and maintenance as the performance of each panel can be individually tracked, whereas with a string inverter, any issues affecting one panel can impact the output of the entire string.
- Q: How does a solar inverter handle power quality issues in the grid?
- A solar inverter manages power quality issues in the grid by utilizing advanced control algorithms and technologies. It actively monitors the grid's voltage and frequency levels, and adjusts the output of the solar system accordingly to ensure compatibility and stability with the grid. This helps in mitigating power fluctuations, voltage sags or swells, and frequency deviations, thereby maintaining a high-quality power supply from the solar system to the grid.
- Q: Are there any ongoing maintenance requirements for a solar inverter?
- Yes, there are ongoing maintenance requirements for a solar inverter. Regular cleaning of the solar panels to remove dust and debris is necessary to maintain optimal performance. Additionally, inspections and tests of the inverter's components, such as cables and connections, should be conducted periodically to ensure everything is functioning properly. Monitoring the inverter's performance and addressing any issues promptly is also crucial for long-term maintenance.
- Q: Are solar inverters weatherproof?
- Yes, solar inverters are weatherproof. They are designed to withstand various weather conditions including rain, snow, and extreme temperatures. The enclosures of solar inverters are typically made of durable materials that provide protection against moisture and other environmental factors.
- Q: What is the power factor of a solar inverter?
- The power factor of a solar inverter is a measure of how effectively it converts the DC power generated by solar panels into AC power that can be used by electrical devices. A high power factor indicates efficient conversion, while a low power factor signifies energy losses.
- Q: How does a solar inverter synchronize with the electrical grid?
- A solar inverter synchronizes with the electrical grid by constantly monitoring the voltage and frequency of the grid. It adjusts its own output voltage and frequency to match the grid's, ensuring that the electricity generated by the solar panels is in phase and synchronized with the grid. This synchronization allows the solar power to be seamlessly integrated into the grid, enabling efficient power transfer and preventing any disruption to the supply.
- Q: How do you maintain a solar inverter?
- To maintain a solar inverter, regular inspections and cleaning are essential. It is crucial to check for any signs of damage or loose connections, and make sure the inverter is properly ventilated to prevent overheating. Additionally, keeping the surrounding area clean and free from any debris or obstructions can help optimize its performance. It is recommended to follow the manufacturer's guidelines and consult with a professional for any specific maintenance requirements.
