What do you know about the on grid inverter?

on grid inverter is a special inverter. In addition to converting direct current into alternating current, the output alternating current can be synchronized with the frequency and phase of the mains, so the output alternating current You can go back to the mains. on grid inverters are commonly used in applications where some DC voltage sources (such as solar panels or small wind generators) are connected to the grid.

What are the Rated output power of the on grid inverter?

The unit can be watts or kilowatts. Some on grid inverters may have different rated output power for different output voltages. For example, the on grid inverter can be set to output 240VAC or 208VAC, and the rated output power of the two will be different.

Output voltage: refers to the grid voltage to which the on grid inverter can be connected. If it is a small household on grid inverter, its output voltage will probably be 240VAC. If it is a commercial inverter, its voltage will be 208, 240, 277, 400, 480 or 600VAC, and it may have a three-phase output.

What is the Peak efficiency of the on grid inverter?

Peak efficiency refers to the best efficiency that the inverter can output (efficiency is the output AC power divided by the DC power input by the inverter). In July 2009, the peak efficiency of most on grid inverters on the market could reach 94%, and some could reach 96%. The energy lost is mainly lost as heat energy. In order for the inverter to output the rated power, the input electric power must be greater than the rated power. For example, a 5000W inverter has an efficiency of 95% at full power, so it requires 5,263W of input power (rated power divided by efficiency). If the inverter can output electric energy at several different voltages, it will also have its peak efficiency at each voltage.

What are the requirements for the use of on grid inverters?

1. The on grid inverter requires a wide range of DC input voltage. Since the terminal voltage of the solar cell varies with the load and the intensity of sunlight, although the battery has an important effect on the voltage of the solar cell, the voltage of the battery varies with the battery voltage. The remaining capacity and internal resistance fluctuate, especially when the battery is aging, its terminal voltage varies widely. For example, the terminal voltage of a 12V battery can vary from 10V to 16V, which requires on grid inverters. Ensure normal operation within a large DC input voltage range and ensure the stability of AC output voltage.

2. on grid inverter In medium and large-capacity photovoltaic power generation systems, the output of the inverter power supply should be a sine wave with less distortion. This is because in medium and large-capacity systems, if on grid inverters are used, the output will contain more harmonic components, and higher harmonics will generate additional losses. Many photovoltaic power generation systems are loaded with communications or instrumentation equipment. These devices have high requirements on the quality of the power grid. For medium and large-capacity photovoltaic on grid inverters, in order to avoid power pollution with the public grid, the inverters are also required to output sine wave current.

So we need to use the on grid inverter in our daily life and production. If you want to get more information about the on grid inverter, please connect Shenzhen Sumry Electronics Co., Ltd.
