Home Battery Storage

What is Home Battery Storage?

Home Battery

Home battery storage systems are advanced energy storage devices designed to store excess electricity generated by solar panels. These systems typically use rechargeable batteries, such as lithium-ion or lead-acid, to capture and hold surplus energy produced during peak sunlight hours. This stored energy can then be utilized when solar panels are not generating electricity, such as at night or during overcast days, ensuring a consistent power supply for your home.

Why Would You Need Home Battery Storage?

Why Would You Need Home Battery Storage?

Energy Independence

Home battery storage systems store excess solar energy generated during the day for use at night or during cloudy days. This reduces your reliance on the grid, ensuring a continuous and self-sufficient power supply.

Cost Savings

By using stored solar energy during peak hours when electricity rates are highest, you can significantly lower your electricity bills. This approach also provides a financial buffer against rising energy costs.

Backup Power

Battery storage systems provide a reliable backup power source during grid outages, ensuring that essential appliances and systems, such as lighting, heating, and medical devices, continue to operate without interruption. This enhances your home's resilience and offers peace of mind.

Environmental Benefits

Maximizing the use of renewable energy through battery storage helps reduce your carbon footprint and supports a sustainable future. By storing and using more of the solar energy you generate, you contribute to lower greenhouse gas emissions and a greener environment.

How Does a Solar Battery work with Home Solar Panels?

Solar Battery Work Process


Energy Generation

Home solar panels harness sunlight to generate electricity through the photovoltaic effect.

When sunlight strikes the solar cells within the panels, it causes electrons to be released, creating an electric current. This electricity is produced as direct current (DC) power.


Battery Charging

Excess electricity generated by the solar panels during the day is directed to the solar battery for storage instead of being exported to the grid.

The solar battery charges by storing this surplus energy in chemical form for later use.


Energy Consumption

When energy demand exceeds solar panel output, such as during the evening or on cloudy days, stored energy from the battery is utilized to power home appliances.
This enables homeowners to rely on solar energy even when sunlight is not available, reducing dependency on the grid and potentially lowering electricity bills.

Connection and Control

Solar batteries are connected to the home's electrical system through an inverter, which converts the stored DC electricity into usable alternating current (AC) electricity.

The inverter also manages the flow of electricity between the solar panels, battery, and home, ensuring seamless integration and efficient operation.


Monitoring and Control

Many solar battery systems come with monitoring and control features that allow homeowners to track energy production, storage, and consumption in real-time.
Through user-friendly interfaces or mobile apps, homeowners can monitor battery status, adjust settings, and track energy usage and savings.

Batteries Amounts

How Many Batteries Do You Need?

The number of batteries needed for your home’s solar system depends on your energy consumption, solar system size, backup requirements, battery type and capacity, budget, and potential for future expansion.

Our team at EverPower conducts a thorough assessment to provide personalized recommendations tailored to your specific needs and preferences. With our expertise, you can optimize your solar battery system to meet your energy goals efficiently and effectively.

Energy Consumption

Consider your household's daily energy usage, including appliances, lighting, heating, and cooling systems.

Higher energy consumption requires more battery storage capacity to ensure sufficient power during periods of low solar generation.

Solar System Size

The size of your solar panel array directly impacts the amount of excess energy generated.

A larger solar system will produce more surplus electricity, necessitating additional battery storage to store it for later use.

Backup Needs

Evaluate your requirements for backup power during grid outages.

Determine how much energy you need to sustain essential appliances, systems, such as refrigerators, lights, communication devices, for the duration of an outage.

Battery Type & Capacity

Different battery technologies offer varying storage capacities, efficiency levels, and lifespans.

Consider factors such as depth of discharge, cycle life, and round-trip efficiency when selecting the battery capacity for the needs.


Determine the budget for the solar battery system, including the batteries cost, installation, and any associated components.

Balance your budgetary constraints with your energy storage requirements to find the most cost-effective solution.

Future Expansion

Plan for potential future expansion of your solar system and increased energy needs.

Ensure your battery storage solution is scalable to accommodate additional solar panels or household appliances as your energy requirements evolve over time.

What Grants are Available?

What Grants are Available?

In Ireland, homeowners can take advantage of the SEAI grants, facilitated by EverPower, to receive financial assistance of up to €2,100 for the installation of home battery storage systems. This grant significantly reduces the initial investment required for implementing solar energy solutions, making homeowners more accessible and affordable for homeowners across the country.

With EverPower’s expertise and support, you can benefit from these grants to enhance your home’s energy efficiency and sustainability while enjoying cost savings on your electricity bills.

Home Battery Storage FAQs


How long do home batteries last?

The lifespan of home batteries varies depending on factors such as battery type, usage patterns, and maintenance. Generally, lithium-ion batteries, which are commonly used for home storage, can last anywhere from 5 to 15 years.

Can I install a home battery storage system if I don't have solar panels?

Yes, home battery storage systems can be installed independently of solar panels. However, they are most effective when paired with solar panels to maximize energy savings and self-sufficiency.

When does the home battery storage system operate?

Home battery storage systems operate during periods of high energy consumption, such as evenings, during cloudy weather, or at dusk and dawn when sunlight intensity is lower, or during grid outages when grid power is unavailable.

For example, if your home’s energy demand exceeds what your solar panels can produce, the battery system will supply stored energy to meet the shortfall. Similarly, during a grid outage, the battery system automatically switches on to provide backup power, ensuring your essential appliances and devices remain powered.

What electric devices in the home can use home battery storage?

Home battery storage systems can power a wide range of electric devices commonly found in homes, including lights, appliances, heating and cooling systems, electronics, and more.

Essentially, any electric device connected to your home’s electrical system can benefit from the backup power provided by the battery storage system, ensuring uninterrupted operation during grid outages or times of limited solar production.

Are home battery storage systems environmentally friendly?

Yes, home battery storage systems contribute to a more sustainable and eco-friendly energy ecosystem by enabling the efficient use of renewable energy sources such as solar power.
