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: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:Is the grid side of the grid and the inverter?
Off-grid system power transmission sequence: photovoltaic panels> relays> inverters> relays> electricity load;
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: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.
Q: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.
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: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:Solar grid inverter does not merge into the grid, direct access to the load to the load power supply?
Which depends on the grid inverter in the absence of the grid there is no independent operation of the function of the general grid inverter is the current type, only responsible for the power to the grid, the voltage is maintained by the grid,
Q:What is the PV inverter starting voltage
sine wave becomes narrower and the voltage width in the center of the sine wave is widened and the switching element is always operated in a direction at a certain frequency in a half cycle, A pulse wave train (pseudo sine wave). Then let the pulse wave form a sine wave through a simple filter
