Question

why does the inspect battery message come on?

I have a new Generac whole house natural gas 17 kilowatt. shortly after installation the yellow LED came on and the screen said inspect battery the authorized installer came back and checked all connections and electrical outputs finding nothing wrong. 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? Thanks.

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.

Question

First Oil Change in 17KV Generac unit

Changed my oil for the first time on my 17KV unit and the oil was a very light brown cloudy color. Looked like maybe a little water in the oil but had a good feel to it... Is the factory oil something special and should look like this. My unit runs fine and never had a problem with it. Had some time on the unit during power outages but have seen no issues... Is this oil color normal.

Generac’s 17kw Guardian series automatic standby generataor, model number 6243, will ship out with a SAE 30 conventional oil. Unfortunately, we are unable to definitively determine the color of your unit’s oil without being able to see it. Moreover, after the initial 25 hours of use, we recommend switching from this SAE 30 conventional oil to a 5W30 Synthetic oil, for use in all temperature ranges. If you are concerned about the color of your unit’s oil, we would recommend contacting an independent authorized dealer, for further assistance. To locate an independent authorized dealer in your local area, please use your postal code for searching purposes via the following link: http://www.generac.com/dealer-locat....

There shouldn't be any water in the oil, read the manual a little discoloration is ok
I would do a maintenance each year and have the oil changed
and this 17k will last you a very long time

Check the manual it will tell you how many running hours between oil changes
Synthetic oil is great

Installing an automatic standby generator and an associated transfer switch helps to ensure that loads applied to your unit (i.e. home appliances, sump pump, electronics, etc.) will be powered in the event of an utility outage, whether you are home to start the unit or not. The automatic response features of our air-cooled units initiates the unit’s startup, whenever utility power is lost. Conversely, while our portable generators are capable of supplying power to applied loads, in the event of a utility outage, these units require that someone is present to manually start the unit, and some unit portable units are not recommended for use on sensitive electronics or appliances, unlike our air-cooled generators. To obtain further information for our air-cooled generators and/or portable units, please follow the links below:

http://www.generac.com/all-products...

http://www.generac.com/all-products...

Also, some air-cooled generators come pre-packaged with an associated transfer switch, while others do not. In any case, when utilizing an automatic standby generator, a transfer switch is in fact needed for proper installation. Please note, however, that additional items may be needed including a Group 26R, 12V, 525 CCA (minimum) battery (that of which is not provided with the unit out of manufacturing), depending on the unique configuration of your home. In order to determine the appropriate configuration for a permanent system’s installation in your home, we would recommend contacting an independent authorized dealer in your local area.

A retrofit remote shut off with 17KW good 3-500ft would be great

When power goes out you do not need to have generator stay on all night. Being able to shut off at house to save propane would be such an advantage. There should be some technology out the to do this. Rather than having to go out in middle of night in the storm to hit manual switch.

answer 2
Due to the fact that Generac’s 17kw Guardian Series automatic standby generators are manufactured to automatically respond in the event of a power outage, they will remain on, as long as utility power is unavailable. Considering this, the only way to turn the generator off in the event of an ongoing utility outage is to go out and turn the unit off manually, in accordance with the directions provided in your unit’s owner’s manual. Please note that failing to follow the shutdown procedures could potentially cause permanent damage to both the unit and any appliances being backed up by the generator. Furthermore, Generac does not manufacture a remote shut-off accessory, and modifications made to the unit post-manufacturing will void the product’s warranty.

The 17kW automatic standby generator will need to be installed as described in the installation guidelines that are provided with the unit, and connected to an automatic transfer switch. An appropriate option for your configured automatic transfer switch can be determined by a local independent authorized dealer. These trained individuals will take many factors into consideration, when reviewing the electrical set-up of your home. Additionally, the loads that you desire to back-up in the event of a utility outage will also be taken into consideration. Depending on the transfer switch deemed appropriate for your home’s set-up, wiring may be included with the switch, or your chosen independent authorized dealer will provide the wiring necessary for the installation.

Generac’s automatic standby units have lifting holes at the bottom of each corner of the unit. Using proper nylon lifting straps, they can be fed from back to front, and create a lifting point above the center of the unit. Please note that the use of metal lifting hooks in those holes may scratch the enclosure. Generator lifting information can also be found in the installation guide under the section titled “Site Preparation and Generator Placement.” To locate a copy of the installation guide online, search the model or serial number for your generator here: http://www.generac.com/Service/Manu....

Assuming your aren't talking about runs over 100' long, sure you can. You must do it the right way, and keep weather and moisture out of the splices.

IF Generac customer support and their local installers are the same where you are, its doubtful that they'd tell you the time of day; much less whether it's OK to splice wires. Speak with any electric supply house or big box store for the junction box and related materials you need. It's not a big deal so long as you don't cross-wire any of them.

Get a cold winter kit

Your Generac might have come with 30w oil
that wolud make cranking the engine hard and cause an "underspeed"

So have it changed to Synthetic 5w-30
You might have to recharge the battery

Also check the ground at the generator this could affect the charging and cranking

A unit will show an alarm of “undervoltage” if the generator voltage falls below 60% of nominal for more than five (5) seconds, and the unit will then shut down. Essentially, the generator control panel is seeing that the unit is not putting out the correct voltage, and shuts down to protect your appliances. If you are experiencing an undervoltage alarm, we would recommend contacting an independent authorized servicing dealer.

The automatic standby generators have a battery charger integrated into the control panel. When properly installed, the battery will be charged through the T1 control wire, which pulls from utility power when available, whether the unit is in the AUTO or the OFF position. When utility power is lost and the generator is providing power, the battery charger is powered off of the T1 control wire from the transfer switch utilizing the generator’s output power.

Exactly what wiring needed from 200a ats to 17kw

I am a bit confused with the wiring and schematic. I see the fuses from the 200 for N1, N2 and T1. What is the T1 going to at the generator. Looks like a wire nut to something? Is this required, meaning I require a 3-cond. cable for 240v to the gen?
Also, I see the small knockout on the generator, I supposed I must drill the larger conduit access for the #6 cables and ground? I realize the low voltage wiring is a separate conduit.

The volume and pressure required for the 17kW unit, model number 6242, utilizing propane is 181,000 BTU/hr with 10-12” of water column. When utilizing natural gas, the unit requires 205,000 BTU/hr with 3.5-7” water column.
