Q:Photovoltaic grid-connected inverter without DC emc how will happen
When solar or other light illuminates the PN junction of the semiconductor, a voltage (called a photogenerated voltage) occurs on both sides of the PN junction. This phenomenon is the famous photovoltaic effect.
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
Before making an electrical connection, be sure to use the opaque material to cover or disconnect the PV panel. Exposure to sunlight, photovoltaic arrays will produce dangerous voltages. All installation operations must be done only by qualified technicians.
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 grid inverter is a current source, the output voltage is basically the grid voltage, may be slightly raised.
Q:What are the methods of photovoltaic grid-connected inverter control
The square wave output of the inverter using pulse width modulation integrated circuits, such as SG3525, TL494 and so on. Practice has proved that the use of SG3525 integrated circuits, and the use of power FET as a switching power components, to achieve high performance of the inverter, because the SG3525 has a direct drive power FET capability and has an internal reference source and operational amplifiers and Undervoltage protection, so its peripheral circuit is very simple.
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:The function of photovoltaic grid - connected inverter
In general, single-phase h-bridge is a common configuration of dc / ac-level, but can also be used in three-phase and other configurations.
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:Photovoltaic grid-connected inverter problem
But Baidu Encyclopedia clearly pointed out: the zero line is the secondary side of the transformer leads the neutral point of the line, and the phase line constitutes a circuit for power supply equipment.
Q:The working principle of photovoltaic grid - connected inverter
In the small-capacity inverter generally push-pull inverter circuit, full-bridge inverter circuit and high-frequency step-up inverter circuit three, push-pull circuit, the step-up transformer neutral plug connected to the positive power supply, two power Alternating current, the output to get AC power, due to the power transistor to ground, drive and control circuit is simple, and because the transformer has a certain leakage inductance, can limit the short circuit current, thus improving the reliability of the circuit. The disadvantage is the low utilization of the transformer, driving the emotional load is poor.
