Question

Group size 26 or 26R battery

My 13KW model 005253 generac generator needs a new battery. The manual seems to say group size 26 but when I look at the existing battery, it appears to be a 26R, that is, when you face it with the terminals on your side of the battery, the positive (red) is on the right. Should this be 26R?

If the battery on the unit is low or dead, the “CHARGER MISSING AC” alarm will appear on the unit’s control panel. If/when this particular alarm occurs, we would recommend first checking the T1 fuse in the transfer switch, to ensure that it has not blown, and verifying that the T1 control wire is appropriately applied in the customer connection shelf. Otherwise, if the battery is tested with a voltmeter, and it has fallen below the 12v range required for optimal use, we would recommend replacing the battery as needed. Furthermore, if you do not feel comfortable performing these tasks yourself, we would highly recommend contacting an independent authorized service provider in your local area for further assistance.

If the fuel source supplied to the unit becomes inadequate during operation, the unit will stop, and and an associated alarm would be displayed on the unit's control panel, alluding to the fuel-related issue. To avoid such an occurrence, we would recommend ensuring that fuel is being provided to the unit from an appropriately sized tank, in accordance with your backup power needs. To ensure that you are utilizing the appropriate tank and pressure for your automatic standby generator and associated loads, we would recommend working with your local fuel line provider. Additionally, while it is not commonplace, any issues or damage incurred due to a lack of fuel provided to the unit during operation would not be covered under the product's warranty. If you have any additional inquiries, please do not hesitate to contact us directly at 888-GENERAC (436-3722).

If your automatic standby generator is unable to properly run at any time, the unit's control panel should display a corresponding error code, indicating a particular alarm is active on the unit. Not being able to identify the particular alarm that your unit is currently experiencing, it is difficult for us to attempt to diagnose the potential cause of your unit's current issues. However, given the symptoms that you have described, what we can recommend are the following troubleshooting steps:

First, we would recommend checking the voltage state of your unit's battery; a dead battery cannot be charged and would need to be replaced. You can also make sure that the unit is properly configured for liquid propane use, and ensure that the fuel pressure provided to the unit is adequate; these tasks can be performed by your local fuel line provider. Additionally, we would recommend checking the unit's spark plug (replace if necessary), and making sure that the spark plug boot is installed properly. If the unit is overloaded, reduce the loads placed on the generator. Also, if the oil level is low, fill the unit appropriately for optimal use. Lastly, we would recommend checking to see if the air filter needs replacing, or if the air filter housing is cluttered by debris. If after performing these tasks your current issues persist, we would recommend contacting an independent authorized service provider in your local area for diagnostic work.

For maintenance-related purposes, we would recommend stopping the unit after every 24 hours of continuous use, to perform the checks recommended in your unit’s owner’s manual. If/when the generator is automatically operating during a utility outage, it will shut down if/when utility power returns or when manually shut-off per the instructions provided in unit’s owner’s manual. Moreover, maintenance recommendations are provided in the Maintenance section of your unit’s owner’s manual.

The oil appearing milky would most likely be from condensation, mainly from changing climates. The best way to avoid water getting into the oil is to check the dipstick often and at the first sign of any foaming or milky color to the oil start and run the engine for a while to flash off the moisture. If the oil continues to look “light brown”, change it after running the engine long enough to get it good and hot before draining. Using synthetic motor oil should also give the moving parts of your engine better lubrication and keep condensation in the crankcase to a minimum. Additionally, please note that we would recommend contacting an independent authorized service provider in your local area for diagnostic work, should issues persist, or if you believe that something is wrong with your personal generator.

Question

Correct operaing manual?

Hi. We just bought a house that I was glad to see is equipped with a 17kw propane-fired Generac generator. However, we don't have an operating manual for it. The model number is 0055050--where can I find a manual on-line, or is this something you could send me a copy of? I don't see anything on-line when I search for that model number--is there a manual that covers this model that might not be listed under that number? Thank you.

Question

17kW LP Fuel Comsumption with No Load?

In a previous post it was stated that at full load, the 17kW consumes 2.57 gallons of LP per hour.

What does it consume with no load ???

Our generator is at a weekend cottage. Its possible that the power could go out but there would be little or no load on it. Maybe a couple of digital clocks, night lights, etc... but that would be it.

I'm aware that during the exercise cycle the 17kW runs at 2400 RPM so I would assume that saves fuel.

If no load is required will the generator drop down from 3600 to 2400 RPMs. ???

PS
we have a 1000 gal LP tank and the only thing on it is a 90,000 btu forced air furnace and this generator.

Thanks In Advance

Generac’s automatic standby generators are tested for fuel consumption at 50% and 100% load. As we do not test the unit’s for fuel consumption ratings at no load, we are unable to provide fuel consumption specifications for such use. Also, please note that the unit will run continuously at 3600 RPM during non-exercise operation. If you have any other product-related inquiries, please contact us directly at 888-GENERAC (436-3722).

If you are having issues removing the battery from its assigned compartment within your automatic standby generator, we would recommend either removing the bolt located at the bottom of the unit’s dividing panel/heat shield, just to the left of the unit’s battery (this will free-up space to slide the battery out of the compartment), or contacting an independent authorized service provider in your local area for assistance.

Generac’s automatic standby generators are not compatible with any sort of remote switch; the unit will need to either start automatically, or via manual initiation. Moreover, please note that attempting to modify the unit in any way to enable such remote use will void the product’s warranty. Also, shutting down the unit appropriately is extremely important to ensuring that your unit does not incur any sort of issues. To appropriately stop the generator, we would recommend first turning of the units main circuit breaker. Secondly, if the unit has a GFCI outlet being used, turn off the 15 amp outlet breaker. Next, allow the generator to run for 1 minute without load, to cool down. After this, you can then turn the AUTO/OFF/MANUAL switch to the OFF position. Please note that if the unit will be left off for longer than one hour without utility power present, we would recommend removing the 7.5 amp main fuse from the unit’s control panel, so as to protect the unit’s battery from inadvertently being run down or drained. If you have any other product-related inquiries, please contact us directly at 888-GENERAC (436-3722).

He pulled the 7.5 amp fuse and it reset. It happened again two weeks later. I read on a blog that this is just a maintenance reminder and when it happens again to just navigate through the menu to maintenance alerts and press reset and that should hold it off for another year is this correct?

The “Inspect Battery” alarm is a maintenance reminder that will appear yearly. This is a recommendation to physically inspect the battery, as well as have it tested to ensure it is in good condition. For testing, remove the battery from the generator, and either test it on a separate charger, or at an automotive supply store. If the battery is determined to be low, or in poor condition, replace the battery. If the battery is determined to be in good condition, it can be reinstalled into the unit. To reset the Inspect Battery alarm at the control panel, navigate to the Edit menu, and to the Reset Maintenance option. Once at Reset Maintenance, choose Yes and hit the ENTER key. The maintenance reminder will reappear in 1 year’s time. Please see the attached menu map for assistance.
