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 small use of field-effect transistors while using a DSP conversion controller to improve the quality of the output power makes it very close to the sine wave current.
Q:Three-phase photovoltaic inverter grid, the use of phase-locked loop is what?
In addition to the function of converting DC current into alternating current, the inverter also has the maximum output tracking function (MPPT), overvoltage protection, short circuit protection, island protection, overheat protection, overload protection and DC grounding
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: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: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:Installation and maintenance of photovoltaic grid - connected inverter
, any failure that affects the safety performance of the inverter must be immediately removed before turning on the inverter again.
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
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: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;
