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.

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.
Q:Generally a large grid-connected photovoltaic power plant will have several inverters
Group is the use of a number of grid-connected inverter and grid-connected AC power grid, the advantage is the loss of small, low cost of the cable (because the PV cable is more expensive), eliminating the cost of the convergence box, and multiple
Q:Three-phase photovoltaic inverter grid, the use of phase-locked loop is what?
Photovoltaic inverters for grid-connected photovoltaic power generation systems are primarily capable of receiving DC power from photovoltaic arrays and converting them into sine-wave currents of the same frequency and in phase with the access grid for powering the grid or local loads.
Q:After the PV inverter, how to achieve the same period before the network?
When the voltage, frequency, phase does not meet the requirements, the automatic closing closing pulse.
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: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,
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:What is the difference between low voltage grid connection and medium voltage grid connection?
The difference is that the current at low voltage and the grid is large, the current is small when the voltage is small, followed by the low voltage crossing parameter setting problem (such as PV inverter integrated with inverter and low voltage crossing function, not all photovoltaic inverter
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:PV grid-connected inverter can directly load it?
TL5001 operating voltage range of 3.6 ~ 40V, its internal with an error amplifier, a regulator, oscillator, a dead zone control PWM generator, low voltage protection circuit and short circuit protection circuit
