For
solar inverters, most of them have heard of solar energy, but do not know what an inverter is. (The inverter is actually a power conversion device that converts the direct current in the battery into alternating current.) But with the development of science and technology The promotion of solar inverters has been widely used in our lives.
1. Equipped with a reliable DC switch: the situation of the household system is relatively complex and the location is relatively remote. If the components are short-circuited and grounded, and the after-sales maintenance cannot be carried out immediately, it is likely to cause fire or safety accidents. At this time, you can Let the user disconnect the DC switch to prevent the failure from escalating further.
2. Noise reduction: Home
solar inverters are installed in residential houses. If there is noise during operation, it will bring inconvenience to everyone's life. Most of the noise of the inverter comes from fans and inductors. The inverter should be selected Fanless design, no fans inside or outside, to eliminate noise sources as much as possible. The inductor is generally filled with glue and placed in the aluminum case independently to reduce the current and vibration of the inductor.
3. Using a variety of display methods: when choosing a solar inverter, an LCD display is required, which is intuitive and convenient, and is suitable for some customers who do not have a mobile phone to check real-time power generation. The physical function keys have a short life, and the voice-activated function keys are easy to operate and have a longer life. long. Select the monitoring method, use mobile phones to monitor the operation of power plants, you can query at any time, and manage thousands or even tens of thousands of power plants in a unified way.
4. High power generation: There are many factors that affect the power generation of solar inverters. The first is the stability of the inverter. Once the inverter is abnormal, it needs to be repaired or replaced, at least three or four days, and one or two more. Week, during this period, the loss of electricity bills is very large; the second is the efficiency of the inverter, the three efficiencies of the inverter, the greater efficiency, the weighted efficiency and the MPPT efficiency, the greater impact on the power generation is the weighted Comprehensive efficiency, because the inverter works the most time at less than the rated power; the third is the DC working voltage range, the wider the voltage range, which means early start and late stop, the longer the power generation time, the higher the power generation; Fourth, the MPPT tracking technology has high precision and fast dynamic response speed, which can meet the rapid change of light and improve the efficiency of power generation; fifth, the output voltage range of the inverter should also be wide, preferably between 180-270V, of course It can't be too high. Exceeding 270V will affect household appliances.
