Most solar inverters have heard of solar energy but don’t know what an inverter is. (An inverter is a power conversion device that converts direct current in a leisure battery into alternating current.) But with the Ascension, solar inverters have been widely used in our lives, and there are solar inverters. Solar AC power system.
- Equipped with a reliable DC switch: The situation of the household system is relatively complicated, and the location is relatively remote. If there is a short circuit and grounding of the components, when the after-sales maintenance cannot be carried out immediately, it is likely to cause a fire or a safety accident. Now, allowing the user to disconnect the DC switch prevents the further escalation of the fault.
- talled in residential houses. If there is noise during operation, it will bring inconvenience to everyone’s life. Most of the noise of the power inverter comes from fans and inductors. The inverter should be selected Fanless design. There are no fans inside and outside to eliminate noise sources as much as possible. The inductance is potted with glue as a whole and put into the aluminium casing independently to reduce the current and vibration of the inductance.
- Multiple display methods are used: when choosing a power inverter, there must be an LCD, which is intuitive and convenient. It is suitable for some customers who do not have a mobile phone to query real-time power generation. The physical function keys have a short life, and the voice-activated ones are easy to operate and have a longer life. Choose the monitoring method, and use the mobile phone to monitor the power station’s operation. You can query at any time and manage thousands or even tens of thousands of power stations in a unified manner. The two-way monitoring system can provide active services, problem discovery, fault warning, remote diagnosis and processing functions.
- High power generation: Many factors 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. It takes three or four days at least and one or two at most. Weekly, during this period, the electricity charge loss is very large; the second is the efficiency of the inverter, the efficiency of the three inverters, the greater efficiency, the weighted efficiency and the efficiency of MPPT, the weighted one has a greater impact on the power generation Comprehensive efficiency because the inverter works at less than the rated power for the most time; the third is the DC operating voltage range, the wider the voltage range, it means an early start and late stop, the longer the power generation time, the higher the power generation; Fourth, the precision of MPPT tracking technology should be high, and the dynamic response speed should be fast, which can meet the sharp 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, Can not be too high, exceeding 270V will affect household appliances.
How to choose a high-power household inverter?
Dear friends, you will use inverters at home, and there are many high-power inverters for household use on the market. No matter the product models or brands, there are many choices. Inverters are not a simple matter. However, there are mixed products in the market now. If you want to buy high-quality, high-power household inverters, you need to be very cautious, and you can’t choose inverters blindly. Especially some friends think that cheap products are the most cost-effective, but the use of inverters at home should be considered from the direction of long-term use to have more protection.
A cheap inverter doesn’t mean it’s worth the money. For household high-power inverters, you can’t just look at the price. Many cheap solar inverters are on the market, but they may not meet everyone’s requirements, and even the quality is not the same. It has been used for a long time, which has always been a serious problem. , He affected the normal use of household appliances. Therefore, friends must first determine the prices of most products on the market, understand the average price, and compare performance and quality. It will be more convenient to buy inverters after the overall comparison.
Of course, big brands are more secure. Some customers may feel that the price of a big brand household high-power inverter will be higher. In fact, by comparison, the products of big brands will not be much higher than ordinary products. After all, big brands have mastered cutting-edge technology and have stronger production capacity, so the price must be more cost-effective. Big brands also have high-quality after-sales maintenance services. If you want to buy, choosing high-quality brand products is worthy of everyone’s approval and is the best choice.
But in the choice of the inverter, no matter what brand it is, the internal configuration and the detailed parameters of the machine are given priority. According to personal requirements, choose the inverter that suits you, whether a car inverter or a home inverter; quality and after-sales are the most important.
