Generac RG02515 25kW 3-Phase Generator
The Generac RG02515 3-Phase Generator from the Protector® Series delivers 25,000 watts of automatic standby power, making it an ideal solution for larger homes, small commercial properties, and light industrial applications. Designed to operate on either natural gas or liquid propane, this model combines clean power delivery, smart connectivity, and space-saving design, all in a weather-resistant aluminum enclosure.
This generator features a Generac 1.5L inline 4-cylinder engine running at 3600 RPM, engineered for durability and capable of powering critical systems and sensitive electronics. With True Power™ Technology, the RG02515 ensures less than 5% total harmonic distortion, making it safe for microprocessor-based appliances and office equipment. Its electronic isochronous governor maintains frequency stability within ±0.25% and voltage regulation within ±1%, even during significant load fluctuations.
The unit’s control is managed by Generac’s Evolution™ Controller, which includes a multilingual LCD display and full system status alerts. With Mobile Link™ connectivity included, users can monitor the generator’s status, receive maintenance notifications, and track system history remotely from a smartphone, tablet, or PC.
Designed with convenience and aesthetics in mind, the generator features a RhinoCoat™-powder-coated, all-aluminum enclosure that resists corrosion and meets UL 2200 standards. It operates at 72 dB(A) under load and 59 dB(A) in exercise mode, offering quiet performance in residential or commercial zones. It also supports installations as close as 18 inches from a building (where code permits), making it an excellent choice for space-limited sites.
The RG02515 consumes approximately 2.1 gallons of LP or 221 cubic feet of natural gas per hour at full load, offering fuel efficiency while delivering powerful performance. It’s built with a sealed, pressurized cooling system, long-life fuel and oil filters, and a smart battery charger, all designed to extend service intervals and reduce operating costs.

Bought and shipped the same day. Got lucky that a QT02515 120/208V 3phase generator was sitting around ready to be purchased. Most places said it would be 2 to 4 weeks to be built. The weather here is unpredictable just like the electric company. Might just use this to power the entire house not as a backup instead of relying on another company.
