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: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:What are the methods of photovoltaic grid-connected inverter control
Inverter main circuit need to have a control circuit to achieve, generally have square wave and sine wave two control methods, square wave output inverter power supply circuit is simple, low cost, but low efficiency, harmonic components. Sine wave output is the development trend of the inverter, with the development of microelectronics technology, there are PWM function of the microprocessor has also come out, so the sine wave output inverter technology has matured.
Q:In a photovoltaic grid-connected project, the role of the inverter is to convert the voltage into AC 220V or 380V for the grid, since the transformer will raise the voltage again
Spontaneous use is a way of grid, that is issued to the electricity, mainly their own family or internal use, the excess part of the power to the grid
Q:Three-phase photovoltaic inverter grid, the use of phase-locked loop is what?
Photovoltaic inverters for grid-connected photovoltaic power generation systems are primarily capable of receiving DC power from photovoltaic arrays and converting them into sine-wave currents of the same frequency and in phase with the access grid for powering the grid or local loads.
Q:What is the PV inverter starting voltage
Inverter is a kind of semiconductor device composed of power adjustment device, mainly used for DC power into AC power. Generally consists of boost circuit and inverter bridge circuit. The boost circuit boosts the DC voltage of the solar cell to the DC voltage required for the inverter output control. The inverter bridge circuit converts the boosted DC voltage to the AC voltage of the common frequency. The inverter is mainly composed of a switching element such as a transistor, and turns the DC input into an AC output by repeatedly turning ON-OFF the switching element in a regular manner. Of course, it is not practical to simply output the inverter output waveforms from the on and off circuits
Q:The function of photovoltaic grid - connected inverter
After some additional voltage buffering, the left side of the bridge is usually 18 ~ 20khz switching frequency, the dc voltage is converted to ac voltage.
Q:PV grid-connected inverter can directly load it?
TL5001 operating voltage range of 3.6 ~ 40V, its internal with an error amplifier, a regulator, oscillator, a dead zone control PWM generator, low voltage protection circuit and short circuit protection circuit
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: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?
The inverter is mainly composed of a switching element such as a transistor, and turns the DC input into an AC output by repeatedly turning ON-OFF the switching element in a regular manner.
