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: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: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:Solar grid inverter does not merge into the grid, direct access to the load to the load power supply?
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
Q:How the output voltage of the PV inverter and the grid-connected voltage are determined
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. The car inverter output through the cigarette lighter is 20W, 40W, 80W, 120W to 150W power specifications. And then a large number of power inverter power
Q:Is the PV inverter a current source or a voltage source?
For the inverter for the grid system, depending on whether the transformer can be divided into transformer-type inverter and transformer-free inverter.
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
By dc / dc conversion to increase or decrease the input voltage, adjust its output to achieve maximum efficiency.
Q:Generally a large grid-connected photovoltaic power plant will have several inverters
Inverter, a single failure, does not affect other operations, the impact on the grid is small, high reliability.
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?
