Generac XG03025 Protector Series 30kW 1-phase Generator (CARB Compliant) Features:
Generac XG03025 Protector® Series 30kW 1-Phase Standby Generator
The Generac XG03025 Protector® Series 30kW 1-Phase Standby Generator is a liquid-cooled backup power system designed for larger homes and other applications that need dependable, high-capacity standby power. Delivering a full 30kW on either natural gas or liquid propane, the XG03025 provides 120/240V single-phase power at up to 125 amps, making it a strong option for properties with substantial electrical loads, multiple HVAC systems, pumps, appliances, and sensitive electronics.
The XG03025 combines its 30kW output with a 150-amp circuit breaker, synchronous alternator, high motor-starting capability, and Generac's True Power™ electrical technology. With less than 5% total harmonic distortion (THD) and ±1% digital voltage regulation, the generator delivers clean, stable power suitable for today's electronic equipment and microprocessor-controlled appliances, including variable-speed HVAC systems.
Power comes from a Generac 2.5-liter naturally aspirated inline 4-cylinder engine operating at a low 1,800 RPM during normal operation and 1,200 RPM during exercise mode. The liquid-cooled system uses a belt-driven water pump and two electric fans and is rated for operation in ambient temperatures up to 122°F. An electronic governor with isochronous frequency regulation helps maintain consistent electrical output as loads change during an outage.
The XG03025 also includes Generac's Power Zone® 410 controller and standard Mobile Link® cellular connectivity with Wi-Fi backup, allowing owners to remotely check generator status, maintenance alerts, and readiness. The generator is housed in a corrosion-resistant aluminum enclosure with an electro-galvanized baseframe and stainless-steel exhaust system. Single-side maintenance access, quiet operation, and a 145 mph wind-speed rating further support dependable long-term outdoor installation.

Frequently Asked Questions
How much power does the Generac XG03025 produce?
The Generac XG03025 produces 30kW of emergency standby power on both natural gas and liquid propane. In its single-phase configuration, it provides 120/240V power at up to 125 amps.
Is the Generac XG03025 a single-phase generator?
Yes. This version of the XG03025 is configured for 120/240V single-phase electrical service and includes a 150-amp circuit breaker. Generac also offers the XG03025 in a configurable three-phase version, so it is important to select the model that matches the property's electrical service.
Does the Generac XG03025 produce 30kW on natural gas?
Yes. One of the notable specifications of the XG03025 is that it is rated at a full 30kW on natural gas as well as liquid propane. At 120/240V single-phase, both fuels provide a rated output of 125 amps.
Can the Generac XG03025 run on natural gas and propane?
Yes. The XG03025 is designed to operate on either natural gas or liquid propane vapor. Fuel selection is controller-based, allowing the generator to be configured for the available fuel source without a mechanical fuel conversion.
Is the Generac XG03025 liquid-cooled?
Yes. The XG03025 uses a 2.5-liter Generac liquid-cooled, naturally aspirated inline 4-cylinder engine. It operates at 1,800 RPM under normal conditions and uses a belt-driven water pump and two electric cooling fans.
Is the Generac XG03025 suitable for sensitive electronics?
Yes. Generac's True Power™ electrical technology provides less than 5% total harmonic distortion, while digital voltage regulation maintains output within ±1%. These specifications provide utility-quality power suitable for sensitive electronics, microprocessor-based appliances, and variable-speed HVAC systems.
Does the Generac XG03025 have remote monitoring?
Yes. Mobile Link® remote monitoring is standard on the XG Protector Series. Cellular connectivity with Wi-Fi backup lets owners check operating status, maintenance alerts, and generator readiness remotely using a smartphone, tablet, or computer. Owners can also connect an authorized generator service provider to their account for proactive support.
How much fuel does the Generac XG03025 use?
At 50% load, the XG03025 consumes approximately 1.2 gallons of propane per hour or 283 cubic feet of natural gas per hour. At 100% load, consumption increases to approximately 2.6 gallons of propane per hour or 540 cubic feet of natural gas per hour. Actual fuel usage will vary based on electrical load and operating conditions.
How loud is the Generac XG03025?
The XG03025 is rated at approximately 51 dB(A) at 23 feet during exercise mode and 59 dB(A) at 23 feet while operating at no load. Actual sound levels can vary depending on installation location and surrounding structures.
What is the difference between the Generac XG02525 and XG03025?
The primary difference is output capacity. The XG02525 provides 25kW and 104 amps at 120/240V single-phase, while the XG03025 provides 30kW and 125 amps. The XG03025 single-phase model also uses a 150A circuit breaker compared with the 125A breaker on the XG02525. Both use Generac's 2.5L liquid-cooled engine platform and offer many of the same XG Protector Series features.
Ideal Applications
The Generac XG03025 30kW 1-phase generator is well suited for larger homes, luxury residences, properties with multiple HVAC systems, well pumps, pool equipment, and other substantial electrical loads, particularly where the durability and extended-duty characteristics of a liquid-cooled standby generator are preferred.
