The (H) reading on your unit’s control panel would allude to the amount of time that has passed since your unit was setup for automatic operation. Considering this, if your unit currently reads “2(H)”, this would insinuate that 2 hours have passed since your unit was installed and activated.

Per the unit’s owner’s manual, either a SAE30, 10W-30, or 5W-30 synthetic oil can be utilized on Generac’s Guardian Series automatic standby generators. Please note that our overarching recommendation for use after the unit’s break-in period, would be the 5W-30 synthetic oil, as it is manufactured for use in all temperature ranges. If you have any other product-related inquiries, please contact us directly at 888-GENERAC (436-3722).

Our air-cooled units need to have 18 inches of clearance from the back, 3 ft on either side and in front, 5 ft above, and 5ft from any window, door or vent leading into the home. Moreover, we would recommend ensuring that you will not be restricting the flow of air to the unit, as it is an air cooled generator that requires proper ventilation; any damage due to lack of air provided to the unit is not covered under the product's warranty. Please note, however, that these recommendations are always superseded by local codes.

If the T1 fuse in the transfer switch is blown, the T1 line provided at the generators control panel is not appropriately connected, or if the battery on the unit is low or dead, the “CHARGER MISSING AC” alarm will appear on the unit’s control panel. Considering that you have not hooked up the wiring to your unit at this time, this would likely be the cause of the current reading on your unit’s control panel. If issues persist after all of the wiring has been appropriately applied, we would recommend contacting an independent authorized service provider for diagnostic work. Please note that we would recommend removing the unit’s battery until wiring can be installed, as leaving it connected will cause the battery to drain and render the battery inoperable if/when it is prepared for use.

Generac designs our standby generators with sound attenuated panels and an aluminum, steel, or composite enclosure to minimize noise whenever possible. We make our best effort to manufacture our home standby generators to meet the noise level expectations of our customers. However, there are certain elements of operation that must be considered with an air-cooled engine driven product such as air flow requirements that limit our ability to further sound-proof the enclosure.

Also, please note that Generac’s 20kW automatic standby generator, model number 6730, features a noise rating of 66dB, at a distance of 23 feet, while operating at normal load. Also, when exercising the unit in Quiet-Test mode, the unit will exercise at 60dB, at a distance of 23 feet. Please know that we do not offer other accessories to allow for quieter operation, however, structural or decorative elements, such as a privacy fence, installed at an appropriate distance away from the unit may assist in reducing the noise experienced at a property line. The Guardian Series air cooled automatic standby generators require a minimum clearance of 36” from the ends (short sides) of the generator. However, the distance required from the unit to any window, vent, door, opening into the home, and trees, plants or shrubs over 12” in height is a minimum of 60”. If you have any other product-related inquiries, please contact us directly at 888-GENERAC (436-3722).

The “INSPECT BATTERY” alarm, and associated yellow LED light, allude to a maintenance reminder that will occur on an annual basis. To properly inspect the battery, we would recommend following the recommendations listed in your unit’s owner’s manual. To remove the side panel, merely unlock the unit’s hood, lift it up, and pull the front panel straight up. Once the panel is removed, the battery compartment should be revealed in the lower right hand corner of the unit’s enclosure. If your battery is not appropriately charged, we would recommend verifying that the T1 fuse, along with the T1 connections are appropriately applied in the generator and associated transfer switch. If the battery is dead, it would need to be replaced. If you have any other product-related inquiries, please contact us directly at 888-GENERAC (436-3722).

I am under the impression that you want to see what the generator is capable of handling during a power outage? Other than what you were told.

Whole House Circuit Only

You may want to hire an electrician that has a amp clamp. turn on al your essential circuits and measure for 15 -20 min record in rush amps as well. As you add each additional light monitor amps. a safe load percentage According to NEC for your 20 kw is about 75% load capacity. 65 amps is a safe number. The rest can be used for surge and in rush amps.

Now if you want to know what is hooked up to your emergency panel . Simply turn all lights on and take notes what you have turned on .Kill service entrance breaker and review notes . Whatever is on after generator has took over is Emergency whatever stays off is non emergency . Wall plugs usually are on same breaker that your lights for each room are on .

To test your automatic standby generator for functionality in the event of a utility outage, we would recommend staging such an outage, by setting the unit in the AUTO position, and disconnecting your home’s panel from a main utility feed.

answer 2
When installed appropriately, with the necessary configuration for supplying liquid propane fuel, the slight smell of propane is not uncommon. However, if you are concerned about the strength of the scent, we would recommend referring to your fuel line installer, to ensure that all connections were made appropriately, as a potential leak in the fuel line, or improper installation, could potentially be the cause of a stronger propane smell. Please note that the our automatic standby generators are manufactured for use with a natural gas fuel source out of the factory; the unit would need to be reconfigured for use with a liquid propane fuel source, per the recommendations listed in your unit’s owner’s manual.

An easy way that this can be done is by having your propane company install a level sensor that can give you the ability to monitor fuel level and give you the ability to take action at different settings set at you discretion .for example when it reaches 25 % fuel it can send a message to supplier by email that you will need a fill up... Or you to allow you to take action..

Generac brand automatic standby generators will perform as long as the unit is in the AUTO position, and utility power is absent; there is not a way to set up the system to be disabled after a specified period of time. Furthermore, we recommend stopping the unit after every 24 hours of continuous operation, for maintenance-related purposes described in the unit’s owner’s manual. Please note that any damage incurred to the unit when the unit is utilized for a period of time beyond these recommendations, or damage incurred due to a lack of proper maintenance is not covered under the product’s warranty. If you do not want the unit to run after a specified period of time, we would recommend turning the unit off via the unit’s control panel, and starting the unit back up once you would like to receive back-up power once again.

Question

20KW Guardian -- Detect Run and Disable Unnecessary Loads

I have a 20KW Guardian backing up full utility power to our mountain house. Fuel source is a propane tank. One of the loads on the system is a roof snow melt panel. During a power outage, I would like to disable the snow melt so that it doesn't unnecessarily drain the fuel on the generator. I need advice on how to do this with your system. I see two possibilities:
1) Detect a run indication from your system and use a relay to disable the snow melt. To date, I have been unable to locate a dry contact in either the transfer switch or the generator that indicates when the system running.
2) Use the "load shed" terminals in the transfer switch with a relay to disable loads. Unfortunately, from reading the manual, the load shed terminals do not disable loads, only turn them off temporarily when a "overload" occurs.
Can you advise on a good path forward?

If you are interested in locking out specific loads when the generator is operating, we would recommend considering the use of an Auxiliary Transfer Switch Contact Kit. This product allows the transfer switch installed with the generator to lock out a single large electrical load that you may not need during an utility power outage. Further information on this kit can be located online, by visiting the following link: http://www.generac.com/all-products....

While the unit can in fact be removed for transportation, any damage due to uninstallation and/reinstallation would not be covered. Furthermore, the generator’s warranty coverage is applied only to the original installation site. Once removed from that original installation site, the unit’s warranty will be voided. If you have any other product-related inquiries, please contact us directly at 888-GENERAC (436-3722).
