Q: As a follow-up to my question earlier today what are the main or important differences,if any, between the Generac Guardian 10 kw nat. gas generator Model 5883 and the Model 6439.
by Bob Richardson from New York on May 28, 2013

A: Generac went ahead and improved on the design, warranty and ease of installation after listening to consumer reviews and technicians.

They bumped up the warranty an additional 2 years to give it a solid 5 year overall which is one of the highest rated on the market.

They improved on the generator controller by upgrading to a new technology and moved from their very good Nexus design to the new and improved Evolution controller. This new controller has a back-lit interface with LED's that shows the generator status at a glance.

The new Evolution controller includes maintenance reminders and logs, battery condition (no guessing) and over a half-dozen additional alarms the Nexus controller did not have. This thing rocks!

They upgraded the engine to include a no choke carburetor which helps with all weather starting. They changed the fuel selector for natural gas and LP to an easy knob that is easy to access and change fuel type with ease (No tools required).

For the installers they made several changes to help with installation costs and time, minimize errors and accommodate current and future electric code interpretations by re-engineered some of the wiring connections.

With the changes to the carb and engine they were able to change the low fuel pressure rating for Natural Gas down from 5" of Water Column to 3.5" of Water Column. This will help tremendously with low fuel pressure areas in the country so the meters do not need to be changed as often.

With all of these upgrades they have performed I believe Generac's newest model is one of the best out there and comes highly recommended.

Q: Can you suggest a generator package that will work with the Model 5449 Panel? Looking for something around 8-12kW. Thanks!
by Andres from Massachusetts on June 03, 2012

A: Any of the individual Generac home standby generators will work with model 5449 transfer panel.....here are links to the 8kW, 10kW and the 14kW models available.

Generac Guardian Model 5882 - 8kW

Generac Guardian Model 5883 - 10kW

Generac Guardian Model 5884 - 14kW

Q: Jim I have a 100 amp Pre-Nexus service rated transfer switch. Can I use this with a nexus generator? Ive heard there is some special wiring for the battery charger to work
by Mike Noonan from Michigan on April 18, 2011

A: There is a special kit that needs to be added to the switch to accept the 120V connection which provides the power to the internal generator controller for the charger. These kits are available from your local Generac dealer - Part Number: 0H93030SRV.



by Mike, Product Expert

Q: How far does a generator has to be from my house?
by Jim from Massachusetts on February 04, 2011

A: The manufacturer recommends the back side of the unit to be set no less then 18 inches from any non-combustible surface and the sides of the unit need at least 36 inches for proper intake and exhaust.

Note: It is recommended to check with your city, county and state codes as they may differ from the manufacturers recommendations.

by Mike, Product Expert

Q: What kind of oil comes in the generator, and when it is time to change it? Can I run Mobile 1 Synthetic 5W30 year round in central Oklahoma?
by Ron Hopper from Oklahoma on January 24, 2011

A: The Generac standby generators are shipped with 5W30 oil in them and Generac does give the option to use 5W30 Synthetic in needed. The owner's manual covers all oil options and temperature ranges. Oil changes are determined by use and maintenance is also covered in the manual.

Q: Can this generator be anchored to the slab? If so, can you provide an anchor bolt layout
by Gregg Deemer from Texas on January 21, 2011

A: Generac's model 5885, as with all of their standby generators, are anchored to the pallet at all 4 corners with special anchors which can be used to anchor the unit directly to your concrete base using concrete bolts.

Piece Of Mind For Unexpected Outages
Installation was easy. The plumber and the electrician did a professional job. I haven't had an occasion for it to kick in but I do hear weekly 10 mins exercise cycle. I would be interested in additional soundproffing for the sake of neighbor without compromising air flow.

10kw Standby Generator
Installed 10 kw standby generator and 200 amp transfer switch, fairly easy installation. Unit runs very quiet, starts easy, programming was easy and unit runs every week remotely.

New 10kw Set
All of the hook up was no problem once I found the schematic that matched the transfer and generator that I am using. The main panel which became a sub panel required some modification to the neutral and ground bus bars.

All neutrals must be on one bar and all grounds on the other with no bonding in the sub panel. The service entry transfer switch (200 Amp Generac) is where the neutral and grounds are bonded. It works like a champ.

I used some expansion foam to fill the holes where the... more

Just In Time
The very next day, after finishing the generator install, the power went out for six hours- but not for us!

The Generac fired up automatically and transferred over smoothly. When the power came back on, it transferred back without a blink in the lights!

It has ran almost daily for two weeks now, since we live in Plumas County, and have been surrounded by forest fires. When it runs, it's about as loud as a lawnmower, and it's quieter than our neighbor's generators.

It was easy to... more

Overall Ok
Works OK but not as much information as I would like to see. Not the same information as displayed on the generator. Also, it only records the history if it is on. It will not download the history from the generator.

Highly Recommended
I was satisfied with overall build quality of unit. Several items I feel could be improved.

The termination block inside the unit for power and control wiring was not in keeping with quality of the rest of the unit, in particular I didn't care for the compression type terminations for AC control wires. The inlet cooling screen did not fit snug to the case and left a considerable gap around most of the screen, just perfect for yellow jackets to enter and setup up shop. I sealed the... more

Waiting For A Power Outage
Recently installed 10kW generator. Propane powered, install took awhile, however carefully followed directions supplied by manufacture. Everything works great, and the unit looks great. Cannot wait for first power failure. We live in Northern Michigan and lose power frequently, gets cold very quickly, not this winter. So far very, very pleased.
