Q:What is the difference between low voltage grid connection and medium voltage grid connection?
Have a low pressure through the function set, low pressure through the scope of the project requirements, grid and network requirements and the actual situation of the design), low voltage grid to pass the voltage range is less than the medium pressure, parameter settings are not sensitive and complex.
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:Three-phase photovoltaic inverter grid, the use of phase-locked loop is what?
In addition to the function of converting DC current into alternating current, the inverter also has the maximum output tracking function (MPPT), overvoltage protection, short circuit protection, island protection, overheat protection, overload protection and DC grounding
Q:What is the difference between a grid-connected inverter and an off-grid inverter? What are the advantages of a hybrid inverter?
Grid-connected inverter will be directly sent to the power grid, so to track the frequency of the grid, phase, the equivalent of a current source. Of course, there are some inverters that have a low-pressure through the ability to do PQ adjustment.
Q:PV grid-connected inverter can directly load it?
Converter is the AC voltage of the grid into a stable 12V DC output, and the inverter is the AC output of the 12V DC voltage into high-frequency high-voltage alternating current; two parts are also used with more pulse width
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:Solar grid inverter does not merge into the grid, direct access to the load to the load power supply?
In foreign countries due to the higher penetration rate of the car to go out to work or travel can be connected with the inverter battery drive electrical and various tools work.
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:Photovoltaic grid-connected inverter without DC emc how will happen
light is obtained by the electrons of the semiconductor device, thus generating electrical energy. This energy conversion of light energy into energy, that is, solar cells. Solar cells, like transistors, are made of semiconductors. Its main material is silicon, and there are some other alloys. High-purity silicon used in the manufacture of solar cells is subject to special purification. Solar cells as long as the sun or light exposure,
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
Self-use, do you mean off-grid system? Or else? Europe and Sweden side of the grid project electricity situation is also self-use? If not for their own use or spontaneous use is not used up, sent to other places electricity, you need a transformer?
