When it comes to backup power, there’s no one-size-fits-all solution. Every home has unique energy needs—from powering a few essential appliances during an outage to running your entire household off-grid. That’s why Fortress Power offers scalable energy storage systems designed to fit your lifestyle, budget, and backup goals.

Whether you’re an installer looking for the right system for your client or a homeowner researching energy storage options, this guide will walk you through three turnkey residential packages offered by Fortress Power. These sample setups are a starting point—your exact solution can be customized by a certified installer based on your home’s electrical loads, solar system size, and desired level of backup.

Eco Package

Best for: Basic backup needs — essential appliances and short outages

If your goal is to keep the essentials running (ex: lights, Wi-Fi, your fridge, and small electronics) during brief outages, the Eco Package is a great entry point into home energy storage. It’s compact, efficient, and built to perform in any weather.
