Features

What's built in.

Liquid-cooled, 1800 RPM

An automotive-style liquid-cooled engine built for long runtimes — and much quieter than air-cooled units, the usual choice for strict HOA sound requirements.

Sized 27 to 48 kW

Large homes, 4,500+ sq ft estates, guest houses, multi-AC and multi-structure properties — everything running at once.

Automatic transfer

Senses the outage, starts itself, and carries the property in seconds. Transfers back and shuts down when the grid returns.

Natural gas or propane

Runs on your existing natural gas line or an on-site propane tank sized for days of continuous runtime.

Cellular monitoring built in

Current units ship with cellular monitors — we see faults and outages even when your internet is down.

Installed by both licensed trades

Electrical EC13002031 and gas #24513 in-house — pad, transfer switch, permits, and gas hookup in one fixed written quote.
