Perché le batterie domestiche sono diventate una tendenza globale?

Home battery, often known as household energy storage or household battery storage, it can be utilized as an emergency backup power source when the power grid is down due to disasters or other circumstances, providing the reliability of domestic power supply. Household battery storage, that is, home user-side energy storage systems, will become an important part of the new power system. Energy storage is a key technology to improve the reliability of the power system and promote the consumption of renewable energy.

The rapid rise in the share of VRE (Volatile Renewable Energy) in the power grid would exacerbate the gap between the power generation curve and the power consumption curve. The energy storage setup can transmit electricity over time to help the grid balance power generation capacity and power consumption. Grid-connected and off-grid home battery systems are the most common.

Grid-connected home PV storage systems can either deliver power to household loads from the power grid or send power to the grid. Off-grid home energy storage systems are not connected to the power grid and are appropriate for remote places without power networks, such as isolated islands. Photovoltaics charge the load and batteries at the same time during the day in a home with photovoltaic installations. If there is extra electricity, it can be fed to the grid (depending on local rules). The battery discharges to supply the load at night, and the shortage is compensated for by the power grid. When the power grid fails, photovoltaic power generation and lithium-ion batteries are used to replace the power grid. Furthermore, the battery system allows users to customize their charging and discharging periods to fit their specific power requirements.

In areas where there is no power grid, a home storage system is frequently utilized in connection with photovoltaic. During the day, the photovoltaic power supply powers the load and charges the battery. The battery is discharged to the load at night. If there is still inadequate electricity, a diesel generator, for example, is employed as a backup power supply to the load.

Against the backdrop of rising energy prices, the annual growth rate of global home battery is more than 100%, and Europe has become the largest household energy storage market; additionally, due to insufficient power grid reliability, high reliance on external energy, and disaster prevention, among other factors. The demand for domestic energy storage is being influenced by a variety of variables, such as Japan, Australia, South Africa, Brazil, Southeast Asia and other countries and regions will also continue to increase.

The market driver of Home Battery Installation

Saving the electricity bill

The large gap between feed-in tariff and grid electricity price

Electricity increase / Policy of FIT or Net Metering phase-out, etc.

Subsidy policy

Subsidies to home battery installation

The implementation of time-of-use electricity price

Home battery can be recharged during the valley time and be discharged to the grid during the peak time, to achieve the arbitrage.

Improving the reliability of power supply

To avoid the power outages cased by the grid failures

Grid failures cased by weather event, regional conflicts, disasters, etc.

As a kind of home energy storage, it has obvious channel benefits for to C businesses. Energy storage solutions are electrical items, and installation and commissioning have specific professionalism and safety protection standards. To complete service requirements such as access, installation, and tailored power trading methods, installers in various locations must communicate with local governments, power departments, and customers. As a result, channels suppliers/installers have a significant terminal location advantage.


In the conclusion, the popularity of house batteries stems from the fact that they can improve the efficiency of self-consumption of electricity while also lowering economic costs. The lowering of economic costs and the qualities of “self-sufficiency” are especially significant in the context of the Russia-Ukraine war and the European energy crisis. As electricity prices continue to rise, there is a surge in demand for self-contained renewable energy and energy storage in a number of countries. As one of the most essential components of decarbonization, home battery technologies will undoubtedly improve further, and as costs continue to fall owing to the scale effect, the home battery industry will expand.
