Household energy storage, also known as household energy storage systems,
is similar to micro energy storage power stations, and its operation is not
affected by urban power supply pressure. During periods of low electricity
consumption, the battery pack in household energy storage can be self charged
for backup use during peak or power outages.
Household energy storage can be mainly divided into four types based on
different coupling methods and whether it is integrated into the power grid:
hybrid household photovoltaic+energy storage system, coupled household
photovoltaic+energy storage system, off grid household photovoltaic+energy
storage system, and photovoltaic energy storage energy management system.
The household energy storage adopts the integrated microgrid design
concept, which can operate in both off grid and grid connected modes, and can
achieve seamless switching of operating modes, greatly improving power supply
reliability. In addition, a flexible and efficient management system for
household energy storage configuration can adjust operational strategies based
on the power grid, load, energy storage, and electricity price, achieving system
operation optimization and maximizing user benefits.
Household energy storage system is a new type of hybrid system for energy
acquisition, storage, and utilization, which adds lithium battery storage power
on the basis of traditional photovoltaic grid connected power generation system.
It is composed of batteries, hybrid inverters, and photovoltaic panels. Briefly
introduce the operating mode of household energy storage systems.
1. Morning: Weak light intensity, low energy generation, high energy
demand; At sunrise, the solar panel begins to generate energy and is considered
insufficient to meet the energy needs of the morning; The energy storage system
calls the amount of electricity stored by the battery for use by electrical
appliances
2. Noon: The strongest light intensity, the highest energy output of solar
panels, and low energy demand. The energy generated by solar panels reaches its
peak during the day. But since no one is at home, the energy consumption is very
low, so most of the generated energy is stored in batteries.
3. Evening: Weak light intensity, low energy production, high energy
demand. The highest energy consumption per day is when solar panels generate
little or no energy at night, and the TGPRO energy storage system will utilize
the energy generated during the day to meet energy needs.
