Family villa photovoltaic + energy storage battery system to achieve self-sufficiency in electricity consumption
The smart home energy storage system adopts an integrated home appliance design, which is exquisite and beautiful, and is easy to install. It can supply electricity for residences, public facilities, and small factories. The smart home energy storage system is similar to a micro energy storage power station, and its operation is not affected by the pressure of urban power supply.
Home energy storage system:
Utilize rooftop solar power generation devices, household wind turbines to generate energy, and low-cost power sources from the social power supply system to store the wealthy power in the energy storage system for peak use, which can not only be used as emergency power, but also save families Electricity expenses. The energy storage battery OSM battery company currently provides 5KWH, 10KWH, wall-mounted and stacked styles of energy walls. Such products are very suitable for the needs of household energy storage. Currently, it has obtained the CE certification of the European Union.
During low power consumption, the lithium-ion battery pack in the home energy storage system can be self-charged to be used for backup power peaks or power outages. Most households use 48V energy storage systems, which have 100Ah, 200Ah, and 300Ah to store electricity. In addition to being used as an emergency power source, the smart home energy storage system can also save household electricity expenses because it can balance the electricity load.

The rapid development of overseas home energy storage market
powerwall-10k 48v lithium battery
The overseas home storage market is experiencing rapid development driven by economy and improving the reliability of power supply. The driving factors for the development of Germany/US/Japan/Australia are slightly different. Factors such as the expiration of FIT will drive the further improvement of the economy of home storage, and the virtual power plant (VPP) model is expected to contribute to new income and promote the rapid development of distributed power systems.
The driving factors of the storage market in each country are different, with economy and power supply reliability as the core driving forces. In 2021, the global installed capacity of energy storage will be about 6.6GWh, a year-on-year increase of 46%, of which Germany/United States/Japan/Australia are the main installed capacity countries.
The core driving force for the development of household energy storage
The core driving force of home storage includes reducing the cost of household electricity and improving the reliability of power supply: policies, electricity market mechanisms and other methods jointly drive the cost of distribution and storage to reduce and reduce the cost of household electricity; household energy storage can be used as a backup in the event of a power outage The power supply improves the reliability of home power supply.
►The difference between the grid electricity price and the on-grid electricity price will gradually increase.
►Direct subsidies: The government provides direct subsidies for home storage configuration. For example, the US ITC policy gives tax credits to energy storage projects supporting photovoltaics.
►Time-of-use electricity price mechanism: California, Australia, Italy and other countries have a time-of-use retail electricity price mechanism. During the noon time, the photovoltaic power generation is large, the electricity demand is small, and the residential electricity price is low; The demand for electricity has increased rapidly, and the price of time-of-use electricity has risen.
►Virtual power plant: It can realize stable power transmission to the power grid, and at the same time, through long-term contracts and financial tools, it can reduce the threshold of installation cost and accelerate the penetration rate of household energy storage. For example, Australia and California in the United States both provide income ranging from US$50-100/KW/year for household solar-storage systems to participate in virtual power plant projects.
Huge space for global home storage development
Under the accelerated development of retail/VPP, the global home storage installation scale in 2025 is expected to reach 18/35GWh respectively. According to some scholars, the theoretical scale of global home storage is about 1300GWh, but as of 2021, the installed capacity of global home storage is only about 20GWh, and the development potential is huge. Factors such as the widening of the peak-to-valley price gap, the reduction of energy storage costs, and the expiration of FIT will drive the further improvement of the economy of home storage.
