Understanding Whole House Backup Power Supplies

A whole-house backup power supply is designed to provide continuous electricity to your home during power outages. These systems typically use a combination of a battery bank, an inverter, and a transfer switch to convert stored energy into usable power for your home. They can be scaled to match the size of your home and your specific power needs. A well-designed whole-house backup power supply will ensure that your essential appliances and devices continue functioning, providing peace of mind during a power outage.

Types of Home Battery Backup Power Systems

There are two main types of home battery backup power systems: portable and installed systems.

Portable Backup Power Systems

Portable systems are modular and combine a battery, inverter, and charge controller into a compact unit designed to be mobile. These systems provide backup power to essential devices during an outage. The latest systems have output and capacities designed to handle almost any load. Since these systems are modular, you can start with a smaller system, and easily add to it without additional installation costs.

Installed Backup Power Systems: 

Installed systems are permanently fixed to your home and designed to provide power to the entire house during a power outage. These systems consist of a battery bank, an inverter, and a transfer switch that seamlessly transitions between grid and battery power. Many installed systems are "stackable," so energy storage can be expanded to provide electricity for your entire home during an extended outage.

Key Factors to Consider When Choosing the Best Home Battery Backup Power System


One of the most critical factors to consider when choosing a home battery backup power system is its capacity. Capacity refers to the total energy the battery bank can store, measured in kilowatt-hours (kWh). To determine the best capacity for your needs, consider how many hours of backup power you require and the total power consumption of the appliances you want to run during an outage.

Inverter Size

The inverter is responsible for converting the DC power stored in the battery bank into AC power that your home's appliances can use. When choosing a whole house backup power supply, ensure that the inverter can handle the maximum power output required by your appliances.

Battery Type

Several types of batteries are available for home backup power systems, including lead-acid, lithium-ion, and flow batteries. Each type has pros and cons, with factors such as cost, efficiency, and lifespan playing a crucial role. Research the battery technologies available to determine which type best suits your needs.

Installation and Maintenance

Some home battery backup power systems require professional installation, while others can be set up by the homeowner. Consider the ease of installation and the level of maintenance required when choosing a system. Some systems may also require additional components, such as a transfer switch or charge controller, so factor these in when budgeting for your backup power solution.

Cost and Warranty 

Lastly, consider the overall cost of the system, including installation, maintenance, and any additional components required. Compare the different manufacturers' warranties to ensure you get the best value for your investment. Remember that while portable systems are generally more affordable upfront, installed systems may provide more comprehensive coverage during an outage.

Tips for Choosing the Best Home Battery Backup Power System

Assess Your Needs: Before investing in a home battery backup power system, take the time to assess your specific needs. Determine which appliances and devices are essential during an outage and calculate their combined power consumption. This information will help you select your system's appropriate capacity and inverter size.

Consider Future Expansion: If you anticipate your power needs changing in the future, opt for a system that can be easily expanded or upgraded. For instance, some installed systems allow adding more batteries to increase capacity.

Research Brands and Reviews: Take the time to research different brands and read customer reviews before making a decision. This will give you valuable insights into various home battery backup power systems' performance, reliability, and customer satisfaction.

Consult with Professionals: If you're unsure which system best suits your needs, consider consulting with a professional installer or electrician. They can assess your home's requirements and recommend the most appropriate backup power solution.

Investing in a whole-house backup power supply is wise for any homeowner. Whether you're looking for a portable solution or an installed system, there are plenty of options available to suit your needs.
