The amount of fuel consumed by a 20kw Guardian Series automatic standby generator will vary, depending on the loads that you desire to back up in the event of a utility power outage. Also, fuel consumption varies between different years and makes of particular models. In order to find the fuel consumption information specific to your model, please refer to your unit’s owner’s manual and/or installation guide. Product documentation can be accessed online by using your model or serial number for searching purposes here: http://www.generac.com/Service/Manu....

When your control panel shows a red LED light, it is either recognizing that your unit is currently in the “OFF” mode, or there is an associated alarm message. We would recommend referring to your unit’s control panel to ensure that your unit is not currently experiencing an error code in association with a red LED light. If your unit is displaying an alarm message/error code, we would recommend consulting your manual for suggestions, or contacting an independent authorized service provider for diagnostic assistance.

The serviceman probably did not reset the "oil change required" alarm. Open the top and hold down the enter button to reset the alarm. The yellow light should go off. If that doesn't work, check your manual or do an Internet search to find out how to reset the alarm. It's really pretty simple.

During times where snowfall is expected, we recommend ensuring that snow and/or ice is cleared off of, and away from, the enclosure. There should be no snow piles or large accumulations of snow within five feet of the unit to ensure proper air flow if the unit were needed in an outage.

Question

I am planning a standby generator system for my home.

I have 400 AMP utility service split into (2) 200 amp (30) slot panels.
Each panel has a 60 amp breaker for the 2 electric heat pump furnaces in my home. I heat the house off one of the heat pump systems when we do not have guests to fill the 6 bedrooms. My question is do I need 2 disconnects or can I simply connect to one of the panels for standby power and is 20KW enough.

As specified in the unit’s installation guide, Generac’s air-cooled automatic standby generators should be installed on a level bed of pea gravel or cement base. We do not recommend installing the unit on any pavers or brick-constructed bases. Any damage incurred to the unit due to wrongful or improper installation will void the product’s warranty. Furthermore, we would recommend contacting the dealer for inquiries regarding costs incurred, as the unit would have been purchased through that particular dealer.

Procedure to turn fuel conversion knob

Just received my Guardian 20kw Model 6250. The installation manual says that it might be necessary to use pliers to break free the fuel conversion valve in order to turn it. Inside the unit there is a tag attached to the fuel conversion knob that gives directions that say to push in and turn the knob. Please explain exactly how the knob should be handled - I don't want to damage/break anything.

While Generac’s 20kW Guardian Series automatic standby generators, model numbers 5875 and 6244, are two very similar units, they do have a few slight differences. Each of these generators feature an external main circuit breaker, natural gas or liquid propane operation capabilities, and a low oil pressure shutdown. These units also come pre-wired with a 200 Amp, Service Entrance Rated transfer switch, however, the transfer switch utilized with model number 6244 comes with an aluminum enclosure. Another key difference between these two units pertains to the control panels featured in each. Model number 5875 features the Nexus Controller, whereas model number 6244 features our updated Evolution Controller. As for the fuel pressure required for the optimal performance of the generator, model number 6244 requires 205,000 btu/hour and 3.5-7” water column when operating the unit with natural gas, and 189,000 btu/hour and 10-12” water column for liquid propane. Conversely, model number 5875 requires 206,000 btu/hour and 5-7” water column for natural gas, and 173,880 btu/hour and 10-12” water column for liquid propane use. Further information can be found here: http://www.generac.com/Service/Manu..., by using each model number to search for the unit’s owner’s manual and additional documentation.

As the manufacturer, Generac Power Systems does not supply a battery with its automatic home standby generators. However,
the required battery is a Group 26R, 12V, 525 CCA minimum. When properly installed, the battery charger that is integrated into the control panel will maintain the charge on your battery. Furthermore, replacement batteries can be purchased through your local Generac certified service dealer.

How to connect Generac Guardian 20kw to internet

Is there a simpler approach to connect the unit through my wireless router to access the menu on the unit from my home computer?

Other than the devices that you have alluded to, Generac’s generators do not have internet communication or monitoring capabilities. Our units utilize either a remote or cellular monitor. Currently, there are no provisions enabling customers to connect with the internet via our automatic standby generators.

Question

Induction Load

Just installed whole hse Generator 20kw, i performed a transfer test. Everything ran smooth until primary hot tub pump came on. Its sounded like the pump was whining up and down. I checked the load with an amp probe, it was about 25 amps on each phase. Which is about 30% of the capacity. I shut the hut tub off on the breaker, i turned on most of the loads in my home (60 amps each phase) and there was no problems. I'm wondering if induction Load such as motor is not fooling voltage regulator in the generator, which causes voltage irregularities. Do i need to install choke transformer to bring the harmonics down?

Connie,

Per the Generac Users Guide Page 20:

Red LED Alarm light is on when the generator is OFF or a fault is detected.

The internal display panel should give you the severest fault (if multiple faults have occurred).

Unless the generator is switched off, the red led tells you that you need to call your Generac Certified Repair person.

Good luck,
