Q:After the PV inverter, how to achieve the same period before the network?
When the voltage, frequency, phase does not meet the requirements, the automatic closing closing pulse.
Q:Photovoltaic grid-connected inverter without DC emc how will happen
by means of energy converters can be converted into electrical energy. The process of converting light energy directly into electrical energy is precisely the response to photovoltaic effects. Without the need for any other mechanical parts, the energy in
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: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: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: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: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:Photovoltaic grid-connected inverter problem
The first zero line is the AC output. Any AC output of the inverter will have zero line, whether it is isolated or non-isolated. Isolation is the safety of high voltage inverters and regulators. 50KW above the inverter almost with the transformer.
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
Unless the power is not issued for their own use, is to be sent to other areas, it needs to boost, such as the western region of those large power stations
