Generac 15KW Home Backup Generator - 7034

Product Details

Generac 15KW Home Backup Generator - 7034

Provides essential circuit power protection for your home, ensuring the necessities remain powered during an outage. This affordable automatic standby generator offers protection for about half the cost of central air conditioning.


  • True Power™ Technology
    delivers best-in-class power quality with less than 5 percent total harmonic distortion for clean, smooth operation of sensitive electronics and appliances.
  • Generac’s G-Force Engines
    are purpose built, pressure-lubricated engine capable of handling the rigors of generator use, resulting in power that’s more reliable and requires less routine maintenance than any competitive engine.
  • Tough, Durable All-Aluminum Enclosures
    Our Rhino Coat™ powder coated finish helps make corrosion-resistant aluminum perfect for all weather conditions.
  • Smart, User-Friendly Controls
    Generac’s Evolution™ Controller features a multilingual LCD display that allows you to monitor battery status and track maintenance intervals to ensure your generator is always in top operating condition.


  • Generac G-Force Design
    Maximizes engine "breathing" for increased fuel efficiency. Plateau honed cylinder walls and plasma moly rings helps the engine run cooler, reducing oil consumption resulting in longer engine life.
  • "Spiny-lok" cast iron cylinder walls
    Rigid construction and added durability provide long engine life.
  • Electronic ignition/spark advance
    These features combine to assure smooth, quick starting every time.
  • Oil circulatory system
    Extends maintenance intervals to 500 hours and virtually eliminates oil degradation
  • Full pressure lubrication system
    Pressurized lubrication to all vital bearings means better performance, less maintenance and longer engine life. Now featuring up to a 2 year/200 hour oil change interval.
  • Low oil pressure shutdown system
    Shutdown protection prevents catastrophic engine damage due to low oil.
  • High temperature shutdown
    Prevents damage due to overheating.
  • Optimized muffler and resonator
    Results in dramatically quieter operation during exercise and normal loads than constant speed systems


  • Cylindrically wound rotor
    Allows for multi-phase excitation, enabling variable engine RPM resulting in fuel savings and sound reduction
  • Skewed stator
    Produces a smooth output waveform for compatibility with electronic equipment.
  • Variable speed, constant frequency AVR
    Provides uncommonly clean power with less than 1.5% THD (Total Harmonic Distortion)
  • Automatic voltage regulation
    Regulates the output voltage to ±1% prevents damaging voltage spikes.
  • UL 2200 listed
    For your safety

Evolution™ Controls

  • Auto/Manual/Off illuminated buttons
    Selects the operating mode and provides easy, at-a-glance status indication in any condition.
  • Sealed, raised buttons
    Smooth, weather-resistant user interface for programming and operations.
  • 2-wire Start Interconnection
    Allows the generator to be started by a two wire signal
  • Smart battery charger
    Delivers charge to the battery only when needed at varying rates depending on outdoor air temperature. Compatible with lead acid and AGM-style batteries.
  • Main line circuit breaker
    Protects generator from overload.
  • Electronic governor
    Maintains constant 60 Hz frequency.


  • SAE weather protective enclosure
    Sound attenuated enclosure ensures quiet operation and protection against mother nature, withstanding winds up to 150 mph. Hinged key locking roof panel for security. Lift-out front for easy access to all routine maintenance items. Electrostatically applied textured epoxy paint for added durability.
  • Enclosed critical grade muffler
    Quiet, critical grade muffler is mounted inside the unit to prevent injuries.
  • Small, compact, attractive
    Makes for an easy, eye appealing installation, as close as 18" away from a building.

Installation System

  • 1 ft (305 mm) flexible fuel line connector
    Absorbs any generator vibration when connected to rigid pipe.
  • Direct-to-dirt composite mounting pad
    Complex lattice design prevents settling or sinking of the generator system.
  • Integral sediment trap
    Prevents particles and moisture from entering the fuel regulator and engine, prolonging engine life.
