FAQ

The working principle of photovoltaic grid - connected inverter
Full-bridge inverter circuit to overcome the shortcomings of the push-pull circuit, the power transistor to adjust the output pulse width, the output AC voltage RMS that changes. Since the circuit has a freewheeling circuit, even if the inductive load, the output voltage waveform will not be distorted. The disadvantage of this circuit is that the upper and lower arms of the power transistor are not common, so you must use a special drive circuit or use isolated power supply. In addition, in order to prevent the upper and lower arm co-conduction, must be designed to turn off after the conduction circuit, that must be set dead time, the circuit structure is more complex.s
How the output voltage of the PV inverter and the grid-connected voltage are determined
DC voltage and AC side voltage does not matter, the general PV inverter AC output is 400V / N / PE. With no isolation transformer and output voltage does not matter, grid-connected inverter is the regulation of current, and network voltage depends on the grid voltage. And the grid before the inverter will detect the grid voltage, meet the conditions will be network.s
What is the difference between low voltage grid connection and medium voltage grid connection?
Have a low pressure through the function set, low pressure through the scope of the project requirements, grid and network requirements and the actual situation of the design), low voltage grid to pass the voltage range is less than the medium pressure, parameter settings are not sensitive and complex.s
What is the difference between a PV inverter and a solar inverter?
The main component of the inverter is the three-phase bridge converter. The main purpose of the grid-connected inverter is to change the power to DC and change the AC power. The main purpose is to improve the power quality (because the wind power generation is very larges
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
In a photovoltaic grid-connected project, the role of the inverter is to convert the voltage into AC 220V or 380V for the grid, since the transformer will raise the voltage again
Part of the distributed grid-connected projects, the basic are "spontaneous use, the power of the Internet," these do not need to boost, because the extra power is actually consumed by the surrounding electricity users, do not boost to a Level power grid;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
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.s
