One of the most frequently encountered questions we receive from potential clients is this: why do we choose the Generac brand?
Since 1959, Generac has been designing and manufacturing backup power generators for residential, commercial and industrial applications. They have grown to be the world’s largest provider of residential backup generators, selling five times as many generators as all of our competitors combined. Generac’s broad product line is available through the industry’s largest network of independent generator dealers, retailers and wholesalers.

An automatic backup generator is a back up electrical system that operates whether you are home or away. Within seconds of an outage, it automatically supplies power directly to your home’s electrical circuit breaker box. After utility power returns, the generator shuts itself off and waits for the next outage. It operates on natural gas or liquid propane gas and sits outside just like a central air conditioning unit.

IMPORTANT – To avoid equipment damage, follow these steps, in order, during utility outages.  Shutdowns may be required during utility outages to perform routine maintenance or to conserve fuel.

To turn the generator OFF:

  1. Set the main utility disconnect to OFF (OPEN)
  2. Set the generator MLCB (generator disconnect) to OFF (OPEN).
  3. Allow the generator to run for a cool-down period of approximately one minute.
  4. At the controller, set the generator to OFF.
  5. Remove the 7.5A fuse from the controller.

To turn the generator back ON:

  1. Install 7.5A fuse in controller.
  2. Confirm the generator MLCB (generator disconnect) is OFF (OPEN).
  3. At the controller, set the generator to AUTO mode.
  4. Generator will start and run.  Allow generator to run and warm up for a few minutes.
  5. Set the MLCB (generator disconnect) to ON (CLOSED).
  6. Set the main utility disconnect to ON (CLOSED).

The system now operates in automatic mode.

After you go through these steps, the control panel may go through the programming.  All of your settings should be held there so you’ll have to just hit enter through it (or you can make any adjustments that you need) and get the unit to the main screen (“Switched to off, hours of protection” or “system” is flashing.) Additionally, you will need to reconnect your WIFI if your router is not backed up by the gen.

It is very important to remove the load from the generator prior to shutting down. 

When running the unit during a long term outage, it is vital that you shut the unit down every 24 hours to do a visual inspection of the unit and add any fluids it might need. 

Switch controller to OFF – press OFF button
·         Remove service end of generator for access to battery compartment
·         Disconnect negative ( black ) battery terminal
·         Disconnect T1 connector – see photo below

·         Wait 15 seconds, reconnect T1 connector and then reconnect & tighten negative battery terminal
·         Re-install generator side panel

·         Controller will need to be set up again – time / date, exercise settings.  After this is complete it can be put back in AUTO mode so it is ready to run.

During a utility power outage, an automatic backup generator provides numerous advantages over a portable generator:

  • The American Red Cross recommends permanently installed backup generators as a safer way to provide backup power to a home than a portable generator.
  • With an automatic backup generator properly installed outside, your home is protected from deadly carbon monoxide poisoning that is a much greater risk with portable generators.
  • Running on the home’s natural gas or LP fuel supply, it is less expensive to run than gasoline and sources such as natural gas do not need to be refilled.
  • They start automatically within seconds of a power outage, and eliminate the need to haul a portable generator outside or run extension cords throughout your home.
  • They provide protection 24/7, whether you’re home or away, and they turn themselves off when utility power returns, so there is no need to monitor the unit during an outage.
