Generac 7178 Features:

  • Generac 7178 16kW whole house backup generator is powered by the Generac 816cc G-Force engine with 2 cylinders. It features the True Power Technology, Evolution Controller, removable front and side panels, and weather-resistant, durable all-aluminum enclosure.
  • This 16kW generator offers whole house protection with the 200-amp, NEMA 3R (aluminum outdoor enclosure) smart switch.
  • The engine has a dual fuel carburetion system and runs on liquid propane vapor or pipeline natural gas. The fuel system is configured during installation.
  • The oil tank stores up to 2.2 quarts of oil. The air-cooled gas engine runs on various speeds using the G-Flex variable speed technology.
  • The digital voltage regulation is -+1%. The automatic voltage regulation system maximizes regulation, optimizes response to changing load condition and provides maximum motor starting capability making it great for all climates.
  • FREE Mobile Link™ allows users to check the status of their generator from anywhere in the world, including the weather conditions at home. The control panel alerts the operator using an alarm when there is a faulty condition so it can be remedied.
  • This 60Hz air-cooled model protects itself for long life. It shuts down when it senses low oil pressure, high temperature, over crank, over or under-speed, controller fault, wiring error, over or under voltage and so forth. This extends the life of the generator.
  • Generac 7178 is EPA & CARB compliant, and ETL & UL 2200 certified. It is ideal for residential use and can power up sump pumps, refrigerators, air conditioners, furnaces, computers, monitors, TVs, lights, microwaves and so forth.
  • The model is backed by a 5-year limited warranty.

Generac 7178 16kW whole house generator is the latest addition to the Guardian family. It protects your family during a power outage. This generator produces clean energy with a good sine wave for all your household appliances.

The air-cooled generator can be run on LP or natural gas. During a power outage, the generator will sense the outage and start on its own. It will run efficiently until the grid power returns.

Whole-house coverage, low emissions, low THD at -5%, low maintenance, weather-resistant aluminum casing, and Wi-Fi capabilities make this model a number one choice with modern homeowners.

The engine is pressure-lubricated and the oil circulation system is designed to extend maintenance intervals. Users do not have to change the oil every 100 hours and can wait till 200 hours to do the task.

TRUE POWER™ TECHNOLOGY makes the model perfect for use with sensitive electronics that have micro-circuitry. With less than 5% Total Harmonic Distortion you can use it for almost all devices and electronics with microchips that are used daily. This includes modern HVACs, laptops, cell phones, and tablets.

It is an easy generator to operate with its smart, user-friendly controls. Generac’s Evolution™ Controller features a multilingual LCD display that lets you check the run time, battery status, maintenance intervals and so forth.

Generac 7178 is purpose-built and is designed for extended use. It runs on both LP and natural gas. Built in the U.S.A., this home standby generator is engineered to save you money on installation while offering the same reliability and peace of mind you get from all Generac® home standby generators.

    Great customer support from this website. Added a few a load control modules and as a result save ourselves a bunch of money. shipped the same day we ordered it. Being in logistics not the easiest thing to do on an item weighing about 600lbs.

    Generac's 7178 16kW generator was the perfect size for our application. when we started our search for a generator we thought we would need a 20kW generator. After working with the customer service representatives who were very knowledgeable we determined we only needed a 16kW generator. Great working with people who know their stuff but more importantly did not try and sell us something that we did not need. Love this place
