Energy Storage, Sized for Your Life
A fast way to explore Fortress Power battery and inverter options for your home.
There’s no one-size-fits-all solution when it comes to energy storage. Your daily energy use, location, and lifestyle all influence the right system size. Use this tool to get a recommended Fortress Power configuration based on your estimated daily usage. From there, our team will complete a full system design to ensure your solution delivers the backup power, performance, and flexibility you expect.
We’ll also put you in touch with a certified installer in your area to help you with planning.
Estimate Your Ideal Home Energy Storage System
Enter your average daily electricity use (kWh/day). While the average U.S. home uses about 30 kWh/day, your usage may be higher or lower depending on household size, climate, home efficiency, electric appliances, and daily habits.
This recommendation is for guidance only—final system sizing is completed by a Fortress Power expert.
Want to go further on what system is the best fit for you?
Before you buy a single component, use the Fortress Power System Recommendation Tool to map out your build. Enter your loads, application type, panel information and your backup goals — and the tool will size your battery and inverter configuration based on what you actually need. It takes the guesswork out of system sizing and helps you avoid the two most common DIY mistakes: undersizing storage or overbuying hardware you don’t need. Free to use, no account required.
