The home energy storage system mainly stores the excess power generated by solar panels in the battery pack, which is convenient for the family to use at any time. During the day, when the sun is normal, the solar photovoltaic module generates more energy, which can be stored by the battery to ensure the power at night or another cloudy or rainy day. Also because the battery can optimize the use of electricity, it can ensure the effective operation of the entire home system. At the same time, if there is a sudden suspension of household electricity consumption, for example, if the desktop computer drawings cannot be saved in time in the future, the fresh food in the refrigerator will melt and may deteriorate, etc., but with a home energy storage system, it can maintain continuous power consumption under such circumstances. performance and extremely short response times. The home energy storage system makes solar panel power generation more reliable, avoiding the disadvantage of not being able to generate electricity in rainy days, and affected by the world energy crisis, these systems are becoming more and more common, accepted and loved by everyone, and protect the environment At the same time, it can save energy and generate electricity sustainably.
