Q:Grid-connected inverter is generally divided into photovoltaic power generation grid-connected inverter, wind power grid-connected inverter, power equipment and grid-connected inverter and other power generation equipment power generation inverter.
Grid-connected inverter is generally used with large-scale photovoltaic power plant system, a lot of parallel PV string is connected to the same set of inverter DC input, the general power of the use of three-phase IGBT power module, power
Q:What is the difference between low voltage grid connection and medium voltage grid connection?
When the power grid failure or disturbance caused by the power supply and network voltage drop, in the voltage drop range, the power group can be uninterrupted through the inverter and network operation.
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:How the output voltage of the PV inverter and the grid-connected voltage are determined
DC voltage and AC side voltage does not matter, the general PV inverter AC output is 400V / N / PE. With no isolation transformer and output voltage does not matter, grid-connected inverter is the regulation of current, and network voltage depends on the grid voltage. And the grid before the inverter will detect the grid voltage, meet the conditions will be network.
Q:PV grid-connected inverter can directly load it?
Grid-connected inverter is usually equipped with island protection function, can only receive the power grid, if the load directly, the output is disconnected.
Q:The function of photovoltaic grid - connected inverter
Finally, a sinusoidal AC output for a grid-connected photovoltaic power generation system is generated by a low-pass filter.
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?
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.
Q:What is the PV inverter starting voltage
Photovoltaic inverter, also known as power regulator, according to the inverter in the use of photovoltaic power generation system can be divided into two kinds of independent power supply and grid. According to the waveform modulation method can be divided into square wave inverter, stepped wave inverter, sine wave inverter and modular three-phase inverter. For the inverter for the grid system, depending on whether the transformer can be divided into transformer-type inverter and transformer-free inverter.
Q:Generally a large grid-connected photovoltaic power plant will have several inverters
, This method is simple to design, easy maintenance, but also for the power grid harmonics smaller, good power quality!
