Product Description:

1.   Structure of Solar On-grid Inverter 5kw 2MPPTs 5000TL Description

A solar inverter, or PV inverter, or Solar converter, converts the variable direct current (DC) output of a photovoltaic (PV) solar panel into a utility frequency alternating current (AC) that can be fed into a commercial electrical grid or used by a local, off-grid electrical network. It is a critical BOS–component in a photovoltaic system, allowing the use of ordinary AC-powered equipment. Solar inverters have special functions adapted for use with photovoltaic arrays, including maximum power point tracking and anti-islanding protection.

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:Solar grid inverter does not merge into the grid, direct access to the load to the load power supply?
In foreign countries due to the higher penetration rate of the car to go out to work or travel can be connected with the inverter battery drive electrical and various tools work.
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: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 PV inverter starting voltage
The inverter not only has the function of direct current conversion, but also has the function of maximizing the performance of the solar cell and the system fault protection function. (With grid system), automatic voltage adjustment function (for network connection), DC detection function (for network connection), DC grounding detection (for network connection), automatic power control function Function (for grid connection). Here is a brief introduction to automatic operation and shutdown function and maximum power tracking control function.
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: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: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.
Grid-connected inverter is generally used with large-scale photovoltaic power plant system, a lot of parallel PV string is connected to the same set of inverter DC input, the general power of the use of three-phase IGBT power module, power
Q:What is the difference between low voltage grid connection and medium voltage grid connection?
Have a low pressure through the function set, low pressure through the scope of the project requirements, grid and network requirements and the actual situation of the design), low voltage grid to pass the voltage range is less than the medium pressure, parameter settings are not sensitive and complex.
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.
