Product Description:

1. Structure of 500KW Solar Inverter for Solar Power Plant or Solar Power System without Transformer 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: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: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: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
In the small-capacity inverter generally push-pull inverter circuit, full-bridge inverter circuit and high-frequency step-up inverter circuit three, push-pull circuit, the step-up transformer neutral plug connected to the positive power supply, two power Alternating current, the output to get AC power, due to the power transistor to ground, drive and control circuit is simple, and because the transformer has a certain leakage inductance, can limit the short circuit current, thus improving the reliability of the circuit. The disadvantage is the low utilization of the transformer, driving the emotional load is poor.
Q:PV grid-connected inverter and independent inverter in the control of what is the difference
Photovoltaic grid-connected inverter is the assembly of the DC into AC power for the use of load, or do not use the load, the inverter after the AC power to the city power grid, when the electricity outage, the inverter will automatically
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:The function of photovoltaic grid - connected inverter
In general, single-phase h-bridge is a common configuration of dc / ac-level, but can also be used in three-phase and other configurations.
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 without DC emc how will happen
by means of energy converters can be converted into electrical energy. The process of converting light energy directly into electrical energy is precisely the response to photovoltaic effects. Without the need for any other mechanical parts, the energy in
Q:Generally a large grid-connected photovoltaic power plant will have several inverters
Inverter, a single failure, does not affect other operations, the impact on the grid is small, high reliability.
