Three sizes of
staying powered.

Batteries, inverters, and enclosures — with or without solar. The only real question is how much of the load you want to carry, and for how long.

— TIER 01 · SMALLEST

Emergency Backup.

13.5 kWh · one battery · one sub-panel

Pick the circuits that matter — fridge, modem, two bedrooms, the garage door — and we wire them to a dedicated 40A backup panel. Everything else goes dark, which is exactly why this lasts days instead of hours.

— WHAT MAKES IT DIFFERENT

It's deliberately small. That's the feature.

A whole-home system burns 13.5 kWh in about six hours running AC. The same battery, restricted to essentials, runs three days. If your outages are long rather than frequent, small-and-disciplined beats big-and-thirsty.

— TIER 02 · MIDDLE

Whole Home Backup.

40.5 kWh · three batteries · full 200A panel

Three times the storage of the emergency tier, wired to the main panel instead of a sub-panel. No circuit triage, no "which breaker is on backup" conversation — the whole house rides through.

3 × cell · 200A hybrid inverter
— WHAT MAKES IT DIFFERENT

200 amps of passthrough, and AC that keeps running.

The emergency tier can't start a central AC compressor — 22 kW of surge capacity can. That single spec is the real line between the two tiers. Add solar and the batteries refill each day, turning a two-day system into an indefinite one.

Residential Communities.

1.2 MWh per cabinet · scales to 12 MWh

One pad-mounted cabinet on common ground, serving 20 to 300 homes. Built for developers, HOAs, and build-to-rent operators who'd rather install resilience once than sell it door to door.

— WHAT MAKES IT DIFFERENT

Nothing goes inside anyone's garage.

The hardware lives on a shared pad — a landscaped enclosure roughly the size of a compact car — and feeds the community distribution loop. Residents get backup with no equipment, no maintenance, and no capital outlay. The community meter shaves peaks year-round and earns grid-services revenue between outages.
