Solar On Grid Inverters, Grid Tied Solar Inverter

Products

Solar On Grid Inverter controls the whole system. Solar Inverters converts the DC current  produced by the solar array into AC current, then the Solar On Grid Inverters transfers AC current to the grid, and adjusts the operation point in real-time according to the variation of sunshine to realize the maximum power point tracking (MPPT).

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: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: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:What is the difference between a PV grid-connected inverter and an off-grid inverter?
Grid-connected inverter will be directly sent to the power grid, so to track the frequency of the grid, phase, the equivalent of a current source. Of course, there are some inverters called low-voltage crossing ability, you can do PQ adjustment
Q:What is the PV inverter starting voltage
Inverter is a kind of semiconductor device composed of power adjustment device, mainly used for DC power into AC power. Generally consists of boost circuit and inverter bridge circuit. The boost circuit boosts the DC voltage of the solar cell to the DC voltage required for the inverter output control. The inverter bridge circuit converts the boosted DC voltage to the AC voltage of the common frequency. The inverter is mainly composed of a switching element such as a transistor, and turns the DC input into an AC output by repeatedly turning ON-OFF the switching element in a regular manner. Of course, it is not practical to simply output the inverter output waveforms from the on and off circuits
Q:Photovoltaic grid-connected inverter problem
Hello, the definition of the zero line is not caused by the transformer three-phase electric tail connection? I now do not understand why there is no isolation transformer AC output marked is N (zero line), and it is not the transformer three-phase power of the tail connection leads to, this is the zero line? The The
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?
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: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!
