Generac XG03025 Protector Series 30kW 3-phase Generator (CARB Compliant) Features:
Generac XG03025 Protector® Series 30kW 3-Phase Standby Generator
The Generac XG03025 Protector® Series 30kW 3-Phase Standby Generator is a liquid-cooled backup power system designed for properties that require dependable three-phase emergency standby power. Delivering a full 30kW on either natural gas or liquid propane, the XG03025 combines Generac's liquid-cooled engine platform with configurable three-phase voltage, high motor-starting capability, advanced controls, and remote monitoring.
A major advantage of the XG03025 is its configurable three-phase electrical output. The generator is factory configured for 208/120V 3-phase and can be reconfigured by the installer for 240/120V or 480/277V 3-phase using an optional Generac Voltage Configuration Cartridge (VCC). At its full 30kW rating, the XG03025 supplies 104 amps at 208/120V, 90 amps at 240/120V, or 45 amps at 480/277V. This flexibility makes one generator platform suitable for several common three-phase electrical systems.
Power comes from a Generac 2.5-liter naturally aspirated inline 4-cylinder engine operating at 1,800 RPM during normal operation and 1,200 RPM during exercise mode. The liquid-cooled design is engineered for reliable operation during extended outages, while an electronic governor helps maintain consistent frequency as electrical demand changes. Generac's True Power™ technology produces less than 5% total harmonic distortion (THD) with ±1% digital voltage regulation, providing clean, stable power for sensitive electronics, microprocessor-controlled equipment, and variable-speed HVAC systems.
The XG03025 also features Generac's advanced Power Zone® 410 controller and standard Mobile Link® cellular connectivity with Wi-Fi backup. Owners can remotely check generator status, maintenance alerts, and readiness from a smartphone, tablet, or computer. A corrosion-resistant aluminum enclosure, electro-galvanized baseframe components, stainless-steel exhaust system, single-side maintenance access, and a 145 mph wind-speed rating add durability for demanding outdoor installations.

Frequently Asked Questions
How much power does the Generac XG03025 3-phase generator produce?
The Generac XG03025 produces 30kW of emergency standby power on both natural gas and liquid propane. Depending on its voltage configuration, it provides 104 amps at 208/120V, 90 amps at 240/120V, or 45 amps at 480/277V three-phase.
What three-phase voltages are available on the Generac XG03025?
The XG03025 3-phase model is factory configured for 208/120V. It can be reconfigured by the installer for 240/120V or 480/277V using the appropriate optional Generac Voltage Configuration Cartridge. This gives the XG03025 flexibility to work with several common three-phase electrical systems.
Does the Generac XG03025 produce the full 30kW on natural gas?
Yes. The Generac XG03025 is rated for a full 30kW of emergency standby power on either natural gas or liquid propane. The rated amperage depends on the selected three-phase voltage configuration.
Does the Generac XG03025 3-phase generator include a circuit breaker?
The three-phase XG03025 comes standard with a molded case switch (MCS). Optional field-installable circuit breaker kits are available. Generac identifies a 125A 3-pole breaker as typical for 30kW at 208/120V, a 100A 3-pole breaker as typical at 240/120V, and a 60A 3-pole breaker as typical at 480/277V.
Can the Generac XG03025 run on natural gas and propane?
Yes. The XG03025 can operate on natural gas or liquid propane vapor. Fuel configuration is selected through the controller rather than requiring a mechanical fuel conversion.
Is the Generac XG03025 liquid-cooled?
Yes. The XG03025 uses a 2.5-liter Generac naturally aspirated inline 4-cylinder liquid-cooled engine. It operates at 1,800 RPM under normal operation and uses a belt-driven water pump with two electric cooling fans.
Is the Generac XG03025 suitable for sensitive electronics?
Yes. Generac's True Power™ electrical technology produces less than 5% total harmonic distortion, while its digital voltage regulation maintains output within ±1%. This provides utility-quality power suitable for sensitive electronics, microprocessor-controlled equipment, and variable-speed HVAC systems.
Does the Generac XG03025 have remote monitoring?
Yes. Mobile Link® connectivity is standard on the XG Protector Series. Cellular connectivity with Wi-Fi backup lets owners remotely monitor generator operating status, maintenance alerts, and readiness from a smartphone, tablet, or computer.
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 consumption varies based on load and operating conditions.
How loud is the Generac XG03025?
Generac rates the XG03025 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 the installation and surrounding structures.
What is the difference between the Generac XG03025 1-phase and 3-phase generators?
Both versions provide 30kW of standby power on natural gas or propane, but they serve different electrical systems. The 1-phase XG03025 provides 120/240V single-phase power at 125 amps and includes a 150A circuit breaker. The 3-phase version can provide 208/120V, 240/120V, or 480/277V three-phase power and comes standard with a molded case switch.
Ideal Applications
The Generac XG03025 30kW 3-phase generator is well suited for properties with three-phase electrical service, including shops, offices, small commercial buildings, agricultural facilities, larger residences with specialized electrical systems, and other applications requiring reliable three-phase standby power.
