We support the energy transition in the United States through smart home energy storage. Discover what a home battery can do for you and your household.
Across the United States, more and more households are investing in solar power. A home battery is the next smart step. It allows you to store excess solar energy, reduce reliance on the grid, cut electricity costs, and gain greater control over your home’s energy use – especially as power prices fluctuate and grid stability becomes a growing concern.
A home battery is an energy storage system for your house, similar to a large rechargeable battery. When your solar panels produce more electricity than your home needs, the excess energy is stored in the battery instead of being sent to the grid.
Later, when your solar production drops, such as in the evening, at night or on cloudy days, the battery supplies power to your home. This way you can use more of your own solar energy instead of buying electricity from the grid.
By increasing your self-consumption, a home battery helps lower your energy bills and gives you more control over how and when you use your solar power. It is a smart step toward greater energy independence and sustainability.
A home battery offers a smart way to take control of your energy use. Instead of sending excess solar power back to the grid, you can store it and use it later when your panels are not producing, such as in the evening or during cloudy weather. This is especially useful in areas with low net metering rates or limited compensation for solar exports.
By using more of your own solar energy, you lower the amount of electricity you need to buy from the grid. Even without solar panels, a battery can help you save. You can charge it when electricity is cheaper, for example at night, and use that energy when prices are higher during the day. This reduces your energy bills and gives you more control over your electricity costs.
A home battery also provides peace of mind during power outages, which are becoming more frequent in parts of the United States. It can keep essential appliances running, like lights, refrigerators, internet routers and medical devices, so you’re not left in the dark when the grid goes down.
In addition, a battery reduces your reliance on the power grid and helps relieve pressure on the system, especially in areas with aging infrastructure. With smart apps and software, modern battery systems let you monitor your energy usage and automate charging or discharging based on your daily routine, weather conditions or energy needs.
The capacity of a home battery, measured in kilowatt-hours (kWh), indicates how much energy it can store. Choosing the right size depends on several factors, including your daily electricity usage, the size of your solar panel system, whether you want backup power during outages, and the type of energy pricing in your area.
For some households, a battery with 5 kWh of capacity is enough to cover overnight usage. Others may need a larger system of 10 to 15 kWh or more to power their home for longer periods or to support higher energy demands.
To make the best choice, it’s important to look at your energy habits and goals. A personal energy analysis can help determine which battery size fits your situation and gives you the best balance between performance and cost.
Currently, there are two main types of home batteries available in the U.S.: hardwired home battery systems, which are larger and permanently installed, and so-called plug-in home batteries. Below, you can learn more about the differences between these two types of home energy storage.
Plug-in batteries (also known as plug-and-play systems) are compact units that can be connected using a standard wall outlet. They’re typically more affordable than fully installed systems and ideal for anyone looking for a simple, flexible solution – whether you're in a rental, a vacation home, or a regular household that just wants a hassle-free setup.
Fixed home batteries are permanently installed and connected directly to your electrical system, often together with a hybrid inverter and solar panels. They offer greater storage capacity, higher power output, and full integration with your energy usage and smart home systems. These are ideal for homeowners looking for maximum energy independence and long-term performance.
It depends on how you use your battery, your local energy prices, and the type of system you choose. In some cases, payback can happen within just a few years. In others, it may take longer. But regardless of return on investment, home batteries offer something even more valuable: energy freedom, peace of mind during outages, and a smarter, more sustainable way to power your home.
