Q:After the PV inverter, how to achieve the same period before the network?
Grid simulator: analog power grid, normal and abnormal conditions, overvoltage, undervoltage, over frequency, under frequency, sudden power failure, etc.
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:Installation and maintenance of photovoltaic grid - connected inverter
Before the installation should first check whether the inverter in the transport process for damage. When selecting the installation site, there should be no interference with any other power electronic equipment in the surrounding area.
Q: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.
Q:The function of photovoltaic grid - connected inverter
Finally, a sinusoidal AC output for a grid-connected photovoltaic power generation system is generated by a low-pass filter.
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:What is the difference between a PV grid-connected inverter and an off-grid inverter?
Grid-connected inverter does not need energy storage, but the energy can not be controlled, the number of photovoltaic sent to send online how much, simply do not want people to.
Q:Generally a large grid-connected photovoltaic power plant will have several inverters
, This method is simple to design, easy maintenance, but also for the power grid harmonics smaller, good power quality!
Q: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.
Q:What is the difference between a grid-connected inverter and an off-grid inverter? What are the advantages of a hybrid 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.
