Residential / Battery
Battery backup that keeps the lights on when ERCOT can't.
Whole-home or essential-loads. Sized for the storm — not the average day.
Storage
Uri-grade backup, properly sized.
Most quotes you'll see size battery backup against an average day. We size against extreme events — multi-day grid outages, freeze conditions where your heat strips are running, summer heat where the AC has to keep cycling.
For most Texas homes that means 20–40 kWh of usable storage, paired with a smart load center that prioritizes critical circuits when reserves drop.

What battery actually does
Three jobs, one box.
01
Outage backup
Automatic islanding when the grid goes down. Critical loads stay on without intervention.
02
Self-consumption
Solar production stored for nighttime use — especially valuable on time-of-use rate plans.
03
Grid services
On select utilities and ERCOT programs, your battery can earn revenue by exporting during peak demand.
