FAQ:
Q:How the output voltage of the PV inverter and the grid-connected voltage are determined
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. 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. In foreign countries
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:What is the difference between a PV grid-connected inverter and an off-grid inverter?
Off-grid inverter is equivalent to their own to establish an independent small power grid, mainly to control their own voltage, is a voltage source.
Q:After the PV inverter, how to achieve the same period before the network?
Solar panel simulator: with MPPT function, simulated morning, noon, afternoon, evening, rainy weather, solar panels produced under different conditions in different voltages.
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:Photovoltaic grid-connected inverter without DC emc how will happen
Solar photovoltaic power generation technology is the use of solar cells, the photovoltaic effect of semiconductor materials, solar radiation can be directly converted into a new type of power generation system, solar energy is a radiant energy, solar power means --- to direct conversion of sunlight Into electricity,
Q:What is the difference between low voltage grid connection and medium voltage grid connection?
For photovoltaic power plants when the power system accidents or disturbances caused by photovoltaic power plant grid voltage drop, in a certain voltage drop range and time interval, the photovoltaic power plant can ensure that non-off-line continuous operation.
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:PV grid-connected inverter and independent inverter in the control of what is the difference
The independent inverter in the output voltage phase amplitude of the frequency control is initially set good. Independent inverter, you should refer to off-grid inverter, do not need to consider the grid situation.
