With the development of the power industry, more and more people choose to build their own home backup power supply so that household appliances can still be used normally in case of power failure. The home 12V to 220V power inverter mainly converts the 12V DC stored in the batteryafterthe photovoltaic panel is converted into 220V AC for use by the load, which is the core component of a household backup power supply. Therefore, the selection of solar inverter for home project is extremely important.
What type of residential inverter is better?
According to different standards, there are various types of residential inverters on the market: according to grid-connected and off-grid classification: off-grid inverters, grid-connected inverters and grid/off-grid inverters. According to the phase classification: single phase hybrid inverter, three-phase inverter. According to the output waveform classification: pure sine wave, modified sine wave, and square wave. According to the working mode classification: low frequency inverter and high frequency inverter.
In general, when selecting the type of residential inverter for the family, most of us use single-phase off-grid inverters to assemble solar power systems for power generation. Because when the power environment is unstable, we usually use solar power generation as a backup power source.If the loads used at home are all single-phase, single-phase inverters will be used; if the loads used at home are all three-phase, three-phase inverters should be used for power generation.
Of course, among many types of residential inverters, households also use grid/off-grid inverters. However, the installation of this grid/off-grid solar power generation system needs to be based on the local access policy. The policiesare differentin different places, please consult and refer to the actual policies in your area. The solar power system prioritizes the use of photovoltaic energy. When the photovoltaic energy is insufficient, it can besuppliedby city power or batteries. When the photovoltaic energy is surplus, the batteries are stored or connected to the grid to maximize the use of photovoltaic power generation, thereby achieving the purpose of self-use and additional power consumption.
Selection of residential inverters
Regardless of which brand of residential inverter for photovoltaic system is selected, the internal configuration and detailed parameters of the machine must be considered first. The main parameters of residential inverters are output power, conversion efficiency, DC input voltage, output waveform, and protection function. In this way, if you have an understanding of these parameters, you can know the quality of this residential inverter, and you can also choose a residential inverter suitable for your home.
When purchasing a residential inverter, in addition to the parameters of the inverter, we suggest that you also understand the history of the brand. The ability of a brand to withstand the test of time proves that its products and services have passed the test, and choosing a good brand can save you manypotential problems in the future.
