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: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:Photovoltaic grid-connected inverter without DC emc how will happen
can convert light energy into electricity, so that the current flow from one side to the other, the general can be issued equivalent to 10 to 20% of the received light energy. In general, the stronger the light, the more electricity is generated. Its working principle is based on the semiconductor PN junction of the photovoltaic effect. The so-called photodynamic effect is when the object by the light, the object within the charge distribution of the state of the electromotive force and current generated an effect.
Q:Solar grid inverter does not merge into the grid, direct access to the load to the load power supply?
In foreign countries due to the higher penetration rate of the car to go out to work or travel can be connected with the inverter battery drive electrical and various tools work.
Q:What is the difference between a PV inverter and a solar inverter?
Instability, the wind speed and the equipment itself will directly affect the generator rotation, so the voltage and current fluctuations, frequency instability, in short, is the power quality is poor) Therefore, through the inverter after the first rectification inverter to improve the quality of power
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: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: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: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:Photovoltaic grid-connected inverter problem
The first zero line is the AC output. Any AC output of the inverter will have zero line, whether it is isolated or non-isolated. Isolation is the safety of high voltage inverters and regulators. 50KW above the inverter almost with the transformer.
