Your battery works every day — not just during outages.
Most homeowners think of battery backup as emergency insurance. But the Emporia Home Battery is actively managing your energy costs every single day — whether the grid goes down or not.
Lower your electric bills
The battery charges overnight when electricity rates are lowest, then powers your home during the peak pricing window — typically around 5–9 PM on weekdays. That rate spread can save hundreds of dollars a year.
Solar self-consumption
If you have solar panels, the battery stores energy your panels produce during the day — so more of what you generate stays in your home instead of flowing back to the grid at lower export rates.
Backup + savings in one
Most battery solutions make you choose between emergency backup and energy management. The Emporia Home Battery does both — protecting you during outages and working for you every other day of the year.
Automatic backup for your home.
No fuel, no noise, no manual start — the system switches on in milliseconds and keeps selected circuits running.
Automatic backup
Activates instantly when grid power is lost — no trips to the garage, no action needed from you.
Lower your energy bills year-round
When not responding to a grid event, the battery actively manages your home energy costs — charging during off-peak hours when electricity rates are lowest and powering your home during peak pricing windows. If you have solar, it can also optimize for self-consumption, storing your own generation so more of what your panels produce stays in your home.
Flexible compatibility
Works with existing solar systems and standard electrical panels — no special requirements.
Works alongside your existing generator
Already have a gas generator? The Emporia Home Battery pairs with it — unlike Tesla Powerwall, which is incompatible with gas generators. Propane runs $80+/day during a multi-day outage. The battery handles everyday essentials for free.
Outdoor installation — no interior space needed
Installs outside next to your home, appliance-style. About the footprint of 2 HVAC units. Nothing in your garage.
