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.
The small use of field-effect transistors while using a DSP conversion controller to improve the quality of the output power makes it very close to the sine wave current.
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 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: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
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:Installation and maintenance of photovoltaic grid - connected inverter
Before the installation should first check whether the inverter in the transport process for damage. When selecting the installation site, there should be no interference with any other power electronic equipment in the surrounding area.
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: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?
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.
