A LAYERED BACKUP STRATEGY

Generator, Battery, or Both?

A generator offers long-duration backup while fuel is available. A battery delivers quiet, immediate stored power. In a properly engineered system, combining technologies can provide flexibility beyond either one alone.

▣

Automatic Standby

The generator detects an outage and supplies power through an automatic transfer switch.

◈

Battery + Generator

Coordinate stored energy and fuel-based generation around your loads and runtime goals.

☀

Solar + Storage

Use solar and batteries for everyday energy management with generator backup when appropriate.

✓

Professional Sizing

Account for HVAC, pumps, motor starting, fuel availability and electrical service before choosing capacity.
