Your generator should be running before the lights go out.
SmartSwitch detects grid instability before voltage collapse and pre-starts your generator — seamless transfer, zero interruption.
Conventional ATS units wait for voltage to drop. SmartSwitch uses ROCOF analysis to detect grid stress before failure — and has your generator running before the transfer happens.

The Problem
Conventional ATS units react. SmartSwitch predicts.
A standard ATS waits for voltage to drop below threshold before starting the generator. By then, servers have already crashed, medical equipment has already alarmed, and the building is in the dark. SmartSwitch detects grid instability in the frequency domain before voltage collapse — and pre-starts the generator while grid power is still on.
In South Florida, this is especially valuable during hurricane season, when grid instability precedes outages by minutes.
ROCOF analysis — detects grid instability before voltage collapse
Rate of Change of Frequency analysis identifies grid stress before conventional under-voltage protection fires. Seconds of warning = seamless transfer.
Pre-start logic — generator running before transfer
When instability is detected, the generator pre-starts. Transfer happens after the generator is at voltage and frequency — zero-interruption transfer.
Contact wear monitoring
ATS main and bypass contact resistance trending. Predicts contact replacement need before a failed transfer during an actual outage.
