What are the uses of solar inverters?
The solar inverter is a device that can convert 12V/24V DC power into 220V AC. It is a convenient power converter for general electrical appliances. So what are the applicable scopes of solar inverters?
1. Outdoor equipment
In outdoor activities, digital electronic products such as lighting, electric fans, tablets and mobile phones are mainly used for power supply. The power inverter adopts a portable design with a small size, lightweight, high performance, strong practicability, and durable durability.
2. Household equipment
Usually, DC is directly converted into AC, and then the equipment is powered. Available electrical appliances include desk lamps, electric fans, computers, rice cookers, TVs, refrigerators, washing machines, air conditioners, soybean milk machines, electric kettles, ovens, projectors, hair dryers, induction cookers and most other household equipment.
3. Farms
Irrigation is particularly important in the agricultural industry, especially in arid areas with limited water sources. Still, the intensity and time of light in arid climates are also high, so it is suitable to use solar power generation systems to efficiently carry out farm work. Using the function of solar photovoltaic panels to absorb light radiation, with the help of inverter conversion, it can directly provide electricity for agricultural equipment so that the work of farms will no longer be limited by distance, terrain and electricity and greatly reduce the cost of agricultural operation. Ideally, It is a new green high-tech energy that integrates economy, reliability and environmental protection benefits.
It is suitable for small and medium-sized households, especially remote villages, plateau areas, hills, islands, agricultural and pastoral areas, border posts, etc., far away from the power grid or in areas with underdeveloped electricity for life.
5. Power generation field
Solar power generation can be installed portable and does not occupy too many soil resources. It has the characteristics of a cost-saving investment and safe and reliable power generation. In addition, it can effectively reduce energy input costs, such as communication bases and monitoring systems, and reduce carbon emissions to minimize energy costs. Invest and reduce environmental impact.
6. Transportation
With the help of installing solar powered generator systems to provide power protection for RVs, ships and other means of transportation. Use solar panels to absorb the sun’s light, charge the reserve battery, and then convert it into a daily AC with the help of an inverter. The system is simple in design, easy to install and transport, has zero pollution, no noise, green energy, and safe and reliable operation. The solar power supply system is stable and reliable to meet power problems at any time.
The Importance of Solar Inverters in Solar Energy Systems
As a conversion device for solar power generation, solar inverters play a key role in the overall power station. The solar inverter converts the direct current generated by the solar module into a sinusoidal current, connects the load or merges into the power grid, and is the core component of the solar power generation system. Its main function is to convert the direct current generated by the solar panel into an alternating current for home use.
However, the solar inverter has the function of DC-AC conversion and active operation and deactivation, maximum power tracking MPPT function, island effect inspection and control function.
1. Automatically activate and deactivate functions.
After the sun rises in the morning, the amount of solar radiation gradually increases, and the solar panel output also increases. When the power required by the solar inverter is reached, the inverter will automatically run. After entering the operation, the inverter will always monitor the output power of the solar panel components. As long as the power of the solar panel components is greater than the power required by the inverter target, the inverter will continue to run; until sunset is disabled, the inverter can also run even on rainy days. When the solar panel’s output becomes smaller, and the output of the inverter is close to zero, the inverter will automatically enter the standby state.
2. Maximum power tracking MPPT function.
When the light intensity and temperature change, the input power of the solar module changes linearly. The solar module is not a constant voltage or current source. Its power will change with the output voltage change, and the load is Not directly related. Its output current is a horizontal line at the beginning as the voltage increases. When it reaches a certain power, it decreases as the voltage increases, and when it reaches the open circuit voltage of the component, the current decreases to zero.
3. The inspection and control function of the island effect.
In the case of normal power generation, the photovoltaic grid-connected power generation system is connected to the grid and transmits effective power to the grid. However, the photovoltaic grid-connected power generation system may still work when the grid loses power. And when it operates independently of the local load, this situation is called the island effect. When the inverter has an island effect, it will cause great hidden dangers to the safety of life, the operation of the power grid, and the inverter itself. Therefore, the grid-connected standards for inverters and photovoltaic grid-connected inverters must have island-effect inspection and control functions.
