The system
What you get
A 60 kWh whole-home battery, installed outdoors and fully maintained by Emporia. Hardware, service, and support are covered. You get the backup power.
60 kWh whole-home backup
More than 4x the capacity of a Tesla Powerwall. Roughly 1–3 days of essential-load coverage for a typical home. Activates in milliseconds when the grid goes down.
Hardware serviced by Emporia
Emporia owns the hardware, so maintenance, repairs, and replacements are our responsibility, not yours. No warranty claims to file. If something goes wrong, you call us.
US-based support throughout the program
Emporia's US-based customer service team is available from installation through the life of the program, for questions, post-dispatch follow-up, and anything in between.
Outdoor installation
Installed outside. Nothing in your home, garage, or basement. Footprint of about two HVAC units.
Lower your energy bills year-round
Depending on your utility plan, the battery can actively help manage your home energy costs when not responding to a grid event. It charges during lower-cost off-peak hours and helps power your home during higher-cost peak periods. If you have solar, it also stores excess generation so more of the energy your panels produce stays in your home.
Compatible with solar and generators
Already have a gas generator? The Emporia battery works alongside it. Unlike some competing products, the Emporia battery integrates with your existing gas generator. Have solar panels? It stores the energy your panels produce during the day, helping shift your home onto lower-cost renewable energy instead of higher-cost grid electricity.
Why Connecticut, why now
New England's grid isn't getting more reliable. Your home can be.
Connecticut's grid faces growing stress: summer heat waves, nor'easters, aging infrastructure. There's no single trigger. It's a chronic problem that compounds every year.
But backup power is only part of what the system does for you. If you're on a time-of-use rate plan, the battery charges when electricity costs less and powers your home when rates peak. If you have solar, it stores what your panels produce so more of that energy stays in your home instead of going back to the grid.
You can't predict when the next outage hits. You can decide what your home does every day, and what happens when the lights go out.
Keep what matters running
- Refrigerator and food storage
- Lights and phone charging
- Internet and home office
- Garage and security systems
- Existing gas generator
Manage your energy costs
Charges during off-peak hours, powers your home during peak pricing periods. Especially valuable for United Illuminating customers on time-of-use plans.
Make the most of your solar
