Generac Guardian 24/21 kW Home Standby

The Guardian 24 kW delivers powerful, utility-grade backup in a compact footprint. It includes Wi-Fi/Mobile Link for remote monitoring and proven Guardian features for quiet, efficient operation.

Model options

  • 7209 — 24/21 kW Air-Cooled, Aluminum Enclosure (Generator Only)
    Best when you already have a transfer switch or want a custom whole-home design. Wi-Fi/Mobile Link is included.

  • 7210 — 24/21 kW Air-Cooled + 200A SE (Whole-House) Transfer Switch
    Complete bundle for up to 200A services. The included PWRview™ SE switch adds whole-home energy monitoring.

Output ratings: 24 kW on LP and 21 kW on NG (120/240 V split-phase). True Power™ delivers <5% THD clean power for sensitive electronics.
Placement: permitted as close as 18″ from a structure’s wall (always follow local codes/clearances).

What a 24/21 kW generator can run (typical)

A 24/21 kW unit can back up most essentials plus many comfort loads in gas-heated homes. Actual capacity depends on start surges, altitude, and temperature.

  • Refrigeration & pumps

    • Refrigerator and freezer

    • One or two sump/well pumps (often up to ~1 HP with load management)

  • Heating & cooling

    • Gas furnace or boiler (blower/circulators)

    • Central A/C up to ~5 tons with soft-start or smart load management (varies by LRA).

  • Home essentials

    • Lighting circuits (LED), outlets, garage door opener

    • Internet/router, home office electronics, TVs

    • Kitchen outlets and a microwave; many ranges/ovens can be included if other loads are managed

Rule of thumb:

  • LP (24 kW)100 A at 240 V available for steady loads—keep headroom for motor starts.

  • NG (21 kW)87.5 A at 240 V steady, plus start headroom.

  • Large electric loads (tankless electric water heater, electric dryer, EV charger) usually need smart load shedding or exclusion.

Built-in protection

The generator continuously monitors itself and will safely shut down for:

  1. Low oil pressure

  2. High temperature

  3. Over/under-speed

  4. Controller fault / over-crank

  5. Wiring error

  6. Over/under-voltage

Key performance features

  • True Power™ (<5% THD): utility-grade power for sensitive electronics.

  • G-Force™ engine: purpose-built for generators; durable, low-maintenance design.

  • Quiet-Test™ mode: low-RPM self-test that reduces noise and fuel use.

  • All-aluminum enclosure: RhinoCoat™ finish for corrosion resistance in all weather.

Connected convenience

  • Mobile Link™ monitoring (included): check status, alerts, and maintenance from your phone, tablet, or PC.

  • 7210 bundle: 200A SE whole-house switch with PWRview energy monitoring.
