The home version of the energy storage system has become a topic of concern for more and more families. In the past few years, with the increasing household electricity consumption and rising electricity bills, the demand for home version of energy storage systems is also increasing. Lao Tong’s home energy storage system has been upgraded, using lithium iron battery packs and energy storage inverters and other equipment, which has greatly improved the stability of the energy storage system and the ability to resist impact load. This paper will introduce this set and analyze its economic benefits.
The original home energy storage system was configured as a high-voltage 192-volt DC with a lead-acid battery storage, a Sante 10-kilowatt online UPS inverter, and a timed mains input system with a timer and contactor. The simplicity of the system makes it easy for most users to understand the principle. However, such a system has small power storage and poor impact load resistance, and sometimes the battery voltage is rapidly reduced due to large inductive loads, and even causes the system to alarm and hang up.
The new home energy storage system can recharge the battery while the valley is being used. According to the actual situation of Lao Tong’s home, it takes about 2 hours for the system to be full. Through the timer, the system is automatically introduced to charge when the mains enters the valley at 11 p.m., so that the battery capacity reaches the maximum. The next day, when the household uses electricity, the system will use the stored valley electricity to supply electricity, thus achieving the effect of saving electricity.
