Whole Home Backup Solutions
If you're looking to ensure reliable power during outages or high energy demand, a home battery backup can keep essential devices and appliances running for extended periods. It stores electricity from the grid or renewable sources like solar panels, offering quiet, emission-free energy without the drawbacks of traditional generators. Home battery backups are valued for their ability to reduce electricity costs, enhance energy independence, and efficiently store surplus solar or off-peak power, making them an ideal solution for managing household energy needs.
How to Choose the Right Home Battery
Energy Storage Capacity (kWh)
Energy storage capacity, measured in kilowatt-hours (kWh) or watt-hours (Wh), determines how long your home backup battery can provide power during an outage. Smaller capacities, like 2048Wh, are ideal for running essential devices such as radios, lights, and a few electronics for a few hours. In contrast, larger capacities, like 39.6kWh, can power your home for extended periods, supporting high-demand appliances like washers and dryers. The higher the capacity, the longer and more appliances you can run during an outage.
Scalability
Starting with a smaller system, like a 120V or 2kWh battery, is often sufficient for basic backup needs, but as your home’s energy demands increase, you can expand by adding more battery units. Some systems allow you to scale up to a larger 240V setup and increased battery capacity, offering more power without needing to replace the entire system. Scalable backup batteries provide flexibility and ensure that as your home energy needs grow, your system can easily adapt, keeping your setup future-proof.
Battery Type
The type of battery in your home backup system significantly impacts its performance, longevity, and maintenance. Lithium-ion batteries, like the BLUETTI LiFePO4, are known for their efficiency, offering 3,000+ to 3,500+ charge cycles, making them a long-lasting choice.
Recharge: Methods and Speed
To ensure efficient use of your home backup battery, BLUETTI batteries support both grid and solar charging with input capacities ranging from 2400W to 8000W, offering the flexibility of fast recharge times. This dual charging capability ensures your system is always ready to provide power whenever needed, whether through traditional electricity or renewable energy sources.
Types of Home Battery Systems
Home Battery Backup Without Solar （Standalone Batteries）
A home battery backup without solar is a great option if you’re looking for reliable backup power but don’t have solar panels. These systems pull electricity from the grid and store it for whenever you need it most—whether it’s keeping your lights on during an outage, running your computer in a quiet corner of your home, or even powering up a movie night in the backyard. They're perfect for supporting everyday devices, and in some cases, even more specialized equipment when the power goes out or demand spikes. It's a solid choice for those who want backup energy without the need for solar.

Solar-Powered Whole Home Battery Backup
While a standalone home battery can be incredibly convenient during emergencies or for short-term daily use, adding a solar kit takes things to the next level. For homeowners looking to harness renewable energy, reduce grid dependence, and maximize cost savings, a solar-powered whole home battery backup offers a more advanced and eco-friendly solution.
Off-Grid Home Battery Backup
We know that maintaining reliable power during long-term outages can be a challenge, especially in rural areas. A standard backup battery for home use might not be enough. Off-grid or hybrid home backup systems, with outputs ranging from 7,600W to 18,000W and energy storage capacities between 9.9kWh and 39.6kWh, offer a practical solution for powering essential home appliances like refrigerators, heaters, washers, and dryers, ensuring your home stays fully operational during extended outages. Additionally, many BLUETTI systems come equipped with UPS (Uninterruptible Power Supply) functionality, automatically switching to battery power during an outage, so critical devices remain uninterrupted.

What our customers say?
Do you have any questions?
Yes, battery backup systems are worth it, especially if you experience frequent power outages or want to reduce your dependence on the grid. They provide reliable energy during outages and can be paired with solar panels to store excess power for later use. Over time, they can also help reduce energy bills and provide energy security.
The cost of a home backup battery system varies depending on capacity and brand. On average, a smaller system can range from $5,000 to $10,000, while larger systems with greater storage and power output can cost $15,000 or more. The total cost also depends on installation and any additional equipment required.
Home battery backups generally last between 10 to 15 years, depending on the battery type, usage, and maintenance. Systems like the BLUETTI LiFePO4 batteries can offer up to 3,000 to 3,500 charge cycles, providing reliable performance over the years.
To calculate the battery backup needed for your home, you’ll need to estimate your daily energy consumption. This is done by adding up the wattage of the appliances you plan to power and how long you expect to run them. Multiply each appliance's wattage by the hours of operation, and then sum the total. For example, if you want to run a refrigerator (600W) for 8 hours, that would require 4.8kWh. Once you have your total, choose a battery with enough storage capacity (in kWh) to meet your needs.
