Whole House Battery Backup Cost: Comprehensive Guide 2023

In today's increasingly unpredictable world, having a reliable backup power source for your home has become more important than ever before. Whole house battery backup systems offer a viable solution to ensure uninterrupted power supply during blackouts and emergencies. However, the cost of implementing these systems can vary greatly depending on several factors. In this article, we will explore the key aspects that influence a whole house battery backup cost and additional considerations to help you decide when choosing the perfect backup solution for your home. From battery size and power capacity to installation and maintenance, understanding these factors will enable you to select a system that suits right your needs and budget.

What Factors Affect the Cost of the Whole House Battery Backup Systems

When considering the cost of a whole house battery backup system, there are several factors that come into play.

Battery Size 

The battery size significantly influences the cost of a whole house battery backup system. The larger the battery size, the more expensive the system will be. Battery size is measured in kilowatt-hours (kWh), and the higher the battery's capacity, the more electricity it can store, which increases the system's overall cost.

Power Capacity 

Power capacity refers to the amount of electricity a battery backup system can produce at any given time. A higher power capacity means that the system can provide more electricity during a blackout, which is essential for powering essential appliances like refrigerators, lights, and heating systems. A higher power capacity also affects the system's cost, as systems with higher power capacities are typically more expensive.

Installation 

The cost of a whole house battery backup system can vary depending on various factors, such as the installation process complexity, labor costs, and the location of the installation. The more difficult/complex the installation process, the more expensive the system will be. Additionally, installation costs can also be affected by the location of the installation, as some areas have higher labor costs than others.

Generating Electricity During a Blackout

Some whole house battery backup systems have the ability to generate electricity during a blackout using solar panels or other renewable energy sources. This feature can greatly increase the cost of the system, but it can also provide significant long-term savings by reducing the need to rely on the grid for power. Additionally, systems with this feature can also help reduce the environmental impact of using non-renewable energy sources during power outages.

What other things should you consider when Choosing the Correct Whole House Battery Backup System?

When choosing the correct whole house battery backup system, there are several factors that you need to consider.

Lifespan Expectancy

When choosing a whole house battery backup system, it's crucial to consider the expected lifespan of the unit. A longer lifespan means less frequent replacements and potentially lower long-term costs. Investigate the average life expectancy of the battery models you are considering and compare them to decide on the perfect option for your daily needs.

Battery Chemistry and Efficiency

Lead acid batteries are the most affordable choice for backup power, but their technology is outdated, dating back over a century. Although they can provide power, lead acid batteries have a limited lifespan, typically rated for just a few hundred cycles. In contrast, advanced battery technologies, like lithium iron phosphate (LFP/LiFePO4), can endure thousands of cycles without declining efficiency.

In recent times, the prices of lithium-ion and LFP batteries have dropped significantly as they have become the go-to choice for solar generators, electric vehicles (EVs), and whole-home backup power systems. For instance, our cutting-edge, durable InfiniPower™ technology, paired with LiFePO4 batteries in the Anker PowerHouse 767, is well-designed to last more than 10 years, even with daily usage. Our commitment to quality and innovation earned us a prestigious Red Dot Winner in 2023, making the Anker 767 one of the most reliable and efficient options available today. Investing in innovative battery technologies such as LFP will save money over time.

Maintenance

Maintenance requirements for whole house battery backup systems can vary hugely based on the type and complexity of the system. Some systems may require minimal maintenance, while others may need more frequent check-ups and component replacements. Factor in the maintenance needs of each system and the associated costs when choosing the right backup system for your home. Opting for a low-maintenance system can save you time and money in the long run.

Warranty

A warranty is a critical factor to consider when choosing a whole house battery backup system. A comprehensive warranty can offer you peace of mind and protection against unexpected costs or repairs. When comparing different systems, take note of the warranty terms, including the length of coverage and what components are included. A strong warranty may be an indicator of a manufacturer's confidence in their product, so choose a system with a reliable warranty to ensure you're making a sound investment.

Conclusion

Indeed, selecting the ideal whole house battery backup system is a crucial decision that requires careful consideration of various factors that influence the cost and efficiency of the solution. By understanding the impact of battery size, power capacity, installation, and additional features such as maintenance, warranty, and battery chemistry, homeowners can make an informed choice that meets their energy needs and budget. As technology continues to advance, investing in a reliable, efficient, and long-lasting backup power system will not only ensure uninterrupted power during emergencies but also contribute to a more sustainable and eco-friendly future.

FAQ

Here are some commonly asked queries about a whole house battery backup cost.

How long will whole house battery backup last?

The amount of time a whole house battery backup will last lies in the battery size and power amount required to run essential appliances in the house. A 10 kWh battery backup can power a house's vital functions in at least 24 hours if you aren't relying on AC or electric heat. Now, let's give a rough estimate of how long a 10 kWh battery backup can power different appliances in the house. For instance, a 3,500 W air source heat pump can be powered for under 3 hours, a 300 W TV for 33 hours, a 200 W refrigerator for 50 hours, five 20 W light bulbs for 100 hours, a 25 W phone charger for 400 hours, and a 6 W Wi-Fi router for 1,600 hours.

How much is a battery bank for a house?

The cost of a whole home battery backup system can range from $3,000 to $15,000 before installation. Factors influencing the price include the system's power output and storage capacity, the size of your home, your average electricity usage, and any additional features or requirements. Evaluating your specific needs and consulting with a professional to determine the most appropriate system and accurate pricing for your situation is essential. Remember that installation costs will also need to be factored into the total investment.
