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?
Solar panel simulator: with MPPT function, simulated morning, noon, afternoon, evening, rainy weather, solar panels produced under different conditions in different voltages.
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: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 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:The function of photovoltaic grid - connected inverter
After some additional voltage buffering, the left side of the bridge is usually 18 ~ 20khz switching frequency, the dc voltage is converted to ac voltage.
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: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
Inverter will be converted into alternating current DC, if the DC voltage is low, then through the AC transformer boost, that is, the standard AC voltage and frequency. For large-capacity inverter, because the DC bus voltage is high, AC output generally does not require transformer boost that can reach 220V, in the small and medium capacity of the inverter, because the DC voltage is low, such as 12V, 24V, It is necessary to design a boost circuit.
Q: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;
