With the continuous advancement of global energy transition and the gradual evolution of the electricity market, the importance of energy storage technology in household applications is becoming increasingly prominent. Inventronics offers comprehensive residential energy storage solutions designed to optimize electricity usage, reduce household energy costs, and enhance energy autonomy. Through advanced energy storage batteries, hybrid inverters, and cloud platforms, our systems enable maximum self-consumption of energy, ensuring the stable operation of critical household loads. Whether in urban or rural areas, our residential energy storage products excel in various application scenarios. With flexible energy management strategies, we help households worldwide reduce energy costs and contribute to global energy transition and sustainable development.

1. Self-Consumption and Energy Optimization

Residential energy storage systems integrate renewable energy sources such as solar power to store excess electricity generated during the day for use at night or on cloudy days. This self-consumption model not only reduces reliance on the external grid but also significantly lowers household electricity expenses.

2. Peak-Valley Arbitrage

In electricity markets, there are typically peak and off-peak price differences. Energy storage systems can charge during low-price off-peak periods and discharge during high-price peak periods, helping households optimize electricity costs and achieve economic dispatch.

3. Backup Power (Emergency Power Supply)

Energy storage systems provide backup power for households, ensuring the continuous operation of critical devices (such as refrigerators, lighting, and communication equipment) during grid failures or power outages, thereby maintaining household stability and safety.

4. Smart Energy Management

Through advanced hybrid inverters and cloud platforms, users can monitor and manage household energy usage in real-time via mobile apps. The system automatically adjusts energy storage strategies based on household electricity demand and price fluctuations, maximizing energy efficiency.

5. Demand Response

During grid peak periods, energy storage systems can participate in demand response mechanisms by reducing household electricity demand or supplying power to the grid. This not only helps balance grid load but also generates additional economic benefits for households.

6. Off-Grid and Microgrid Applications

In remote areas or regions with unstable grids, residential energy storage systems can integrate with renewable energy sources to form off-grid or microgrid systems, ensuring stable power supply for households. This application is particularly suitable for rural areas, islands, and other locations lacking reliable grid infrastructure.

7. Electric Vehicle (EV) Charging Support

With the growing popularity of electric vehicles, residential energy storage systems can be integrated with home charging stations to store electricity during off-peak periods for EV charging, optimizing charging costs and reducing grid pressure.

8. Green Energy and Sustainable Development

By adopting residential energy storage solution, households can reduce reliance on traditional fossil fuels, increase the proportion of renewable energy usage, and contribute to global energy transition and sustainable development.

9. Thermal Management and System Stability

Residential energy storage systems are equipped with advanced thermal management technologies, such as air cooling or liquid cooling, to ensure batteries operate within optimal temperature ranges, extending system lifespan and enhancing safety. Whether in high or low-temperature environments, the system maintains efficient and stable operation.

FAQ：

What is Residential Energy Storage and How Does It Work?

Residential energy storage is based on a battery system that stores surplus electricity for later use. When combined with solar energy generated by a photovoltaic (PV) system, these batteries store excess power produced during the day, making it available around the clock. By optimizing the use of electricity, battery storage ensures the efficient operation of a home solar power system and provides seamless backup during temporary power supply interruptions, thanks to its extremely fast response time. This also enhances energy self-consumption: surplus renewable energy generated during the day can be stored locally and used later, reducing dependence on the electricity grid. In this way, a home energy storage battery makes self-consumption more effective.

How Does a Home Battery Energy Storage System Work?

Among various options, lithium-ion battery systems are the most common for residential use. They typically include:

· Battery cells, manufactured by suppliers and assembled into battery modules (the smallest unit of an integrated battery system)

· Battery racks, which connect multiple modules to generate DC current; several racks can be combined

· An inverter, which converts DC output from the battery into AC output for household use

· A Battery Management System (BMS), usually integrated within factory-made battery modules, to monitor and control performance

In a typical setup, solar panels are connected to a controller, which sends electricity to the battery racks or banks for storage. When energy is needed, the current passes through an inverter to convert between AC and DC as required, then through a meter before being supplied to the selected wall sockets.

Can Batteries Be Added to an Existing Solar System?

Yes. Home battery storage can be installed together with a solar power system or retrofitted to an existing one. As battery prices fall and the environmental benefits of solar become more appealing, battery storage is increasingly being adopted to make solar power more reliable.

How Much Energy Can a Home Battery Store?

Storage capacity is measured in kilowatt-hours (kWh) and can range from just 1 kWh to over 10 kWh. Many household energy storage choose a 10 kWh battery, which represents the total available output when fully charged (minus a minimal reserve charge to keep the system running). In practice, most homeowners connect only essential appliances—such as refrigerators, lighting, Wi-Fi, and phone chargers—to the battery. In a complete blackout, a 10 kWh battery can provide power for 10–12 hours, depending on usage. For example, it can run a refrigerator for about 14 hours, a television for 130 hours, or a single LED light for 1,000 hours.

What Are the Benefits of Home Battery Storage?

Household energy storage batteries increase the share of self-produced electricity used within the home, reducing the need to draw from the grid—a concept known as self-consumption. This brings several advantages:

· Lower energy costs by using the grid only when self-generated power is unavailable

· Energy independence, avoiding price fluctuations, supply disruptions, and blackouts

· Lower carbon emissions by maximizing the use of clean, renewable energy from the sun

· Cost-effectiveness, since stored solar energy is free once generated

By integrating a home energy storage system with solar panels, homeowners can achieve greater efficiency, reliability, and sustainability in their energy usage.

What Are the Different Types of Residential Energy Storage Systems?

Residential energy storage systems come in several types, each with distinct strengths and limitations. The main categories include battery-based systems, thermal storage, mechanical storage, hydrogen energy storage, and supercapacitors.

Among these, battery-based systems are by far the most widely used in homes. They store electricity using electrochemical batteries such as lithium-ion, lead-acid, or flow batteries. Their popularity comes from their relatively high energy density, good efficiency, and flexible, modular design. In particular, lithium-ion batteries stand out for their longer lifespan, superior energy density, and overall better performance compared to other battery types.
