Q:What is the PV inverter starting voltage
Photovoltaic inverter, also known as power regulator, according to the inverter in the use of photovoltaic power generation system can be divided into two kinds of independent power supply and grid. According to the waveform modulation method can be divided into square wave inverter, stepped wave inverter, sine wave inverter and modular three-phase inverter. For the inverter for the grid system, depending on whether the transformer can be divided into transformer-type inverter and transformer-free inverter.
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?
When the voltage, frequency, phase does not meet the requirements, the automatic closing closing pulse.
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?
The solar grid-connected inverter is not connected to the grid and can not be directly connected to the load to supply power to the load because there is no voltage.
Q: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 large
Q:Is the grid side of the grid and the inverter?
The grid load side of the grid is the grid. The inverter is an important part of the PV grid-connected system and can not be regarded as an external load. Photovoltaic power generation system is included in both grid and off-grid.
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:Photovoltaic grid-connected inverter problem
The first zero line is the AC output. Any AC output of the inverter will have zero line, whether it is isolated or non-isolated. Isolation is the safety of high voltage inverters and regulators. 50KW above the inverter almost with the transformer.
Q:What is the difference between a grid-connected inverter and an off-grid inverter? What are the advantages of a hybrid inverter?
Grid-connected inverter does not need energy storage, but the energy can not be controlled, how much light to send online to the number of online, simply do not want people to the grid does not like.
