Storing grid electricity in the home usually relies on a Home Energy Storage System (HESS)
Storing grid electricity in the home usually relies on a Home Energy Storage System (HESS) . This system can store electricity when electricity prices are low or there is excess electricity, and release electricity when electricity demand is high or there is a power outage, helping save electricity costs, emergency power supply, and improve energy independence . 1. Main ways of home energy storage Home battery energy storage system This is the most common and mature way of home energy storage, relying on batteries to store electricity, mainly including the following types of batteries: Lithium-ion battery Features : high energy density, small size, long life (10-15 years), high efficiency (90%+). Advantages : fast charging and discharging speed, small footprint, high degree of intelligence. Disadvantages : high price, limited capacity, and attention to fire safety. Applicable scenarios : photovoltaic self-generation and self-use, peak shaving and valley filling, po...
