1. Inverter efficiency
Inverter efficiency refers to the efficiency of the inverter when converting DC power to AC power, simply put, it is the conversion of AC power as a percentage of DC power, of course, for the type of inverter, the efficiency of its difference, the general efficiency of the inverter is 80%~99%. 10kw off-grid inverter efficiency is generally between 80%~90%. The efficiency of grid-tied inverters is generally above 90%. The power of a high-power grid-tied inverter is generally between 95%~99%. The efficiency of hybrid inverter is generally between 85%~95%. The efficiency of inverters can vary by brand and power. It is not difficult to get the efficiency of your inverter, it is usually explained in detail in the product instruction.
2. What factors affect the inverter efficiency?
2.1 Load
The specifics of the load has a certain impact on the efficiency of the inverter, in general, the efficiency of the inverter will be based on the size of the load to make appropriate changes, for example, when the load is larger, the efficiency of the inverter will be improved to meet the load’s power needs. Of course, too high or too low load will cause some damage to the inverter, making the service life of the inverter reduced, which is what you need to pay attention to.
2.2 Environment
Environment is one of the factors affecting the efficiency of the inverter, such as dust and high humidity will have a certain impact on the efficiency of the inverter, take humidity as an example, in high humidity, the internal metal components of the inverter will be corroded, which will make the inverter internal resistance increase, which will cause the efficiency of the inverter to decline, therefore, you need to check the inverter situation on a regular basis, for the damage to the inverter should be repaired or replaced, to ensure that the inverter service life is reduced, this is what you need to pay attention to. or replacement to ensure that the inverter can work normally.
2.3 Inverter working temperature
The inverter will release heat when working, with the rise of temperature, the resistance of semiconductor components will increase, which leads to the efficiency of the inverter decreases, so a good heat dissipation design not only allows the inverter to maintain high efficiency, but also reduces the aging rate of the inverter, which is very important for the inverter, of course, you can choose to install a temperature detection system for your inverter, it can give you timely feedback on the working temperature of the inverter and take corresponding measures when the temperature is high.
2.4 Materials used in inverters
The semiconductor material used in the inverter is generally silicon, but the use of semiconductor materials with lower resistivity can improve the efficiency of the inverter to a certain extent, so it can be seen that the material used in the inverter will have a certain impact on the efficiency of the inverter, therefore, you need to pay attention to the material used in the semiconductor in the inverter when you buy the inverter.
3. What are the benefits of knowing the inverter efficiency for you?
First of all, knowing the inverter efficiency can help you to select the right inverter to reduce the power loss in energy conversion and thus reduce the cost of electricity, which is very important for you. Secondly, it is also very important for environmental protection, knowing that reducing energy loss can reduce greenhouse gas emissions and promote carbon neutrality, which has a positive effect on environmental protection. In short, it is essential for you to understand inverter efficiency.
4. Summary
Inverter efficiency is one of the basic parameters of inverter, which is very important for you, so you need to pay attention to the inverter efficiency when selecting an inverter, and also pay attention to the maintenance of the inverter in your daily use to ensure the efficiency and performance of the inverter, of course, if you still have questions about the inverter, you can consult with the inverter dealers, who will positively answer your questions and make professional answers.
