Generac Guardian 22kW Home Standby Generator with 200-Amp Automatic Transfer Switch

Product Overview

The Generac Guardian 22kW Home Standby Generator (Model 7043) is an automated, permanent backup power solution engineered to provide continuous electricity to an entire residential property during a utility grid failure. Fueled by a choice of liquid propane (LP) or natural gas (NG), this high-capacity stationary system manages entire-house emergency power demands. It initiates an electronic start sequence automatically within seconds of sensing an electrical outage, operating seamlessly until standard municipal power is safely restored.

The package is driven by a purpose-built Generac G-Force engine, a heavy-duty overhead valve (OHV) power plant designed explicitly to withstand the continuous thermal stress of emergency generation. This complete kit includes a 200-Amp NEMA 3R Automatic Transfer Switch (ATS), enabling intelligent load-management that matches the demands of dual central air conditioning units, heavy appliances, and sensitive residential electronics. The entire assembly is housed inside an all-weather, powder-coated aluminum cabinet finished in Bisque, engineered to deliver long-term corrosion resistance in harsh, coastal, or high-humidity climates.

Key Features & Benefits

• 200-Amp Smart Automatic Transfer Switch: Packed with a NEMA 3R rainproof smart switch that manages whole-house distribution safely outdoors, isolating internal circuitry from the main grid during blackouts.

• True Power™ Electrical Technology: Formulates clean, utility-grade power with less than 5% total harmonic distortion (THD), safeguarding sensitive computers, variable-speed appliances, and luxury home electronics.

• Onboard Mobile Link™ Wi-Fi Monitoring: Integrates wireless network connectivity to stream live operational statuses, active runtime data, and immediate maintenance alerts straight to smartphones, tablets, or computers.

• Premium All-Aluminum Housing: Constructed from structural aluminum with a multi-layered Bisque powder coat to prevent rust and degradation in aggressive outdoor environments.

• Comprehensive Safety Control Hardware: Outfitted with automatic system safeguards including overload protection, low-oil automated shutdown, short circuit protection, and integrated automatic voltage regulation (AVR).

• Quiet-Test™ Low-RPM Diagnostic Mode: Programmed to perform its periodic self-test routine at a lower engine RPM, conserving fuel and minimizing localized neighborhood noise pollution.
