Three-phase photovoltaic inverter grid, the use of phase-locked loop is what?
- In addition to the function of converting DC current into alternating current, the inverter also has the maximum output tracking function (MPPT), overvoltage protection, short circuit protection, island protection, overheat protection, overload protection and DC groundings
After the PV inverter, how to achieve the same period before the network?
- It can automatically detect the generator and the grid frequency and voltage, in the frequency, voltage, phase are in line with the requirements of the grid to set the time before the release of the closing signal, so that it can be safely and securely connected.s
Photovoltaic grid-connected inverter without DC emc how will happen
- light is obtained by the electrons of the semiconductor device, thus generating electrical energy. This energy conversion of light energy into energy, that is, solar cells. Solar cells, like transistors, are made of semiconductors. Its main material is silicon, and there are some other alloys. High-purity silicon used in the manufacture of solar cells is subject to special purification. Solar cells as long as the sun or light exposure,s
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.s
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, powers
How the output voltage of the PV inverter and the grid-connected voltage are determined
- supply through the cable to the battery. The use of household appliances connected to the power converter output can be used in the car a variety of electrical appliances. The available electrical appliances are: mobile phones, laptops, digital cameras, cameras, lights, electric razors, CD players, game consoles, handheld computers, power tools, car refrigerators and various tourism, camping, medical emergency appliances Wait.s
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.s
What are the methods of photovoltaic grid-connected inverter control
- Sine wave output inverter control integrated circuits, sine wave output of the inverter, the control circuit can be used microprocessor control, such as INTEL company produced 80C196MC, Motorola produced MP16 and MI-CROCHIP company PIC16C73 and so on, these single-chip microcomputer has a multi-channel PWM generator,s
