Now, the Protector Series offers Code Ready features, including a selection of popular preconfigured options and a variety of code-compliant accessories, ensuring your generator meets local regulations. This series is versatile, adaptable, meets UL standards, and provides a cost-effective solution for your backup power requirements

Innovative Design & Prototype Testing are key components of GENERAC’S success in “IMPROVING POWER BY DESIGN.” But it doesn’t stop there. Total commitment to component testing, reliability testing, environmental testing, destruction and life testing, plus testing to applicable CSA, NEMA, EGSA, and other standards, allows you to choose GENERAC POWER SYSTEMS with the confidence that these systems will provide superior performance.

Test Criteria: Prototype tested, system torsional tested, NEMA MG1-22 Evaluation, Motor Starting Ability

True Power™ Electrical Technology: Superior harmonics and sine wave form produce less than 5% Total Harmonic Distortion for utility quality power. This allows confident operation of sensitive electronic equipment and micro-chip based appliances, such as variable speed HVAC systems.

Mobile Link™ Connectivity: FREE with all Protector Series Home standby generators, Mobile Link Wi-Fi allows users to monitor generator status from anywhere in the world using a smartphone, tablet, or PC. Easily access information such as the current operating status and maintenance alerts. Users can connect an account to an authorized service dealer for fast, friendly, and proactive service. With Mobile Link, users are taken care of before the next power outage.

Solid-State, Frequency Compensated Voltage Regulation: This state-of-the-art power maximizing regulation system is standard on all Generac models. It provides optimized FAST RESPONSE to changing load conditions and MAXIMUM MOTOR STARTING CAPABILITY by electronically torque matching the surge loads to the engine. Digital voltage regulation at ±1%.

Single Source Service Response: From Generac’s extensive service network provides parts and service know-how for the entire unit, from the engine to the smallest electronic component.

Generac Transfer Switches: Long life and reliability are synonymous with GENERAC POWER SYSTEMS. One reason for this confidence is the GENERAC product line is offered with its own transfer systems and controls for total system compatibility.
