A Home Battery isn't just a backup power source — it's the cornerstone of the largest distributed energy resource (DER) network being built in the United States. Pair it with an Emporia EV charger, smart plugs, and a Vue energy monitor, and your home becomes part of a coordinated platform that saves you money, gives you grid independence, and helps stabilize the broader electrical grid.

This article is your starting point for understanding what a Home Battery does, how it works alongside the rest of your Emporia devices, and what the bigger picture looks like.

Three things a Home Battery does for your home:

Lower your bill. The battery stores cheap energy — from your solar panels or from off-peak grid hours — and discharges it during expensive peak periods. Most customers see 30–50% in monthly savings when they pair a Home Battery with the rest of their Emporia setup.

Backup power when the grid goes down. The system provides round-the-clock backup, including load shedding to keep your essential circuits running through extended outages. Optional generator hookup for longer events.

Earn money from your utility. Connected batteries can participate in utility programs that pay you for letting your battery help balance the grid during peak demand. As more of these programs come online, your battery becomes an income-producing asset, not just an expense.

Most home batteries are sold as standalone backup units. Emporia builds them as one node in a coordinated home energy platform.

Vue Energy Monitor measures every circuit in your panel at one-second fidelity, so the platform always knows what's happening in your home.

Level 2 EV Charger can be told to wait for cheap energy or available solar before charging — coordinated with the battery to maximize savings.

Smart Plugs and Thermostats let the platform pre-cool, pre-heat, and shift smaller loads off-peak.

Home Battery stores energy when it's cheap and supplies it when it's expensive — and provides backup when the grid is down.

All four work together through the Emporia app. You set your preferences once, and the platform manages the orchestration.

Emporia's long-range mission is building the largest virtual power plant (VPP) in the country — connecting millions of home batteries to balance the grid from the demand side instead of building more power plants.

Here's the math: peak demand happens roughly 5% of the time. The other 95%, generation capacity sits idle. Instead of building more plants for those peak hours, a VPP dispatches energy from connected home batteries — paying customers for the contribution and stabilizing the grid without breaking ground on new infrastructure.

Get 2 million home batteries connected to the platform, and Emporia can dispatch or absorb energy in any neighborhood in the country. The Rocky Mountain Institute estimates this approach could cut the carbon intensity of the U.S. grid by 70%.

When you install an Emporia Home Battery, you're not just lowering your own bill. You're part of that network.

Home Battery systems are sized to match your home's energy needs. Variables that affect the right configuration:

Because of the variables involved, we work with each customer one-on-one to specify the right system. Schedule a free consultation with our battery team to get started.

Pricing depends on system size, installation complexity, and local incentives or rebates. Our consultation team will walk you through the full cost picture for your home, including:

The Home Battery is fully integrated with the Emporia app. Control it on-demand or set your preferences and let it run intelligently in the background. The battery participates in:
