The engine featured in Generac's automatic standby generators should not require any adjustments out of manufacturing. Considering this, we are unable to provide any insight regarding an engine adjustment. If you are experiencing an issue with your unit's engine, however, we would recommend contacting an independent authorized service provider in your local area for any required diagnostic and/or servicing work. These trained professionals can also provide any applicable warranty coverage to your unit.

As we do not manufacture the batteries that should be utilized in our automatic standby generators, we are unable to provide a life expectancy for them. However, we have found that these batteries commonly last for approximately 2-3 years. To ensure that you are able to maximize the life span of your unit's battery, we would recommend performing the maintenance tasks detailed in the product's documentation, and ensuring that all connections associated with the charging of the battery are appropriately applied. Moreover, if you would like to inquire further about an estimated life expectancy of a particular brand of battery, we would recommend contacting the manufacturer of that battery directly. If there are any questions that we can answer for you regarding a product that we manufacture, please do not hesitate to contact us directly at 888-GENERAC (436-3722).

Question

If local codes prevent the use of black iron pipe on the exterior of a building, is galvanized acceptable to use for the generator?

The City of San Diego will not allow the use of black iron pipe exposed to the elements due to the ocean air corroding this type of piping. The electrical contractor chose the Guardian 22Kw which has one line that sates to only use black iron pipe. So, I am in a bind. As the plumbing contractor I will be unable to pass inspection using black iron pipe and will not warranty my install. Or I will pass inspection with galvanized piping but may void the fuel warranty on the generator. Reading up on todays standards of galvanized dipped piping used for fuel it seems that the zinc flaking is no longer an issue, thus is why it is used here on the exteriors of structures for fuel piping.

Please note that as the product's manufacturer, we do not dictate piping requirements for fuel line installations in your local area. As we have detailed in the unit's owner's manual, "Prior to installation of the generator, the installer should consult local fuel suppliers or the fire marshal to check codes and regulations for proper installation." The only specification that we provide is that the piping provided must be approved by the AGA. Considering this, we would recommend checking with your local codes to see what is required for fuel line piping in your local area.

Question

How often should you run a loss of power simulation if your utility company doesn't have a power failure over a long time period?

I understand that the generator will run its weekly 12 minute engine tests if set up to do so, but this only tests the engine... the electrical generating capacity and the automatic transfer switch will not be tested

If I don't experience a utility power outage for a long period of time, should I run a loss of power "simulation" by tripping the Generac 200 amp breaker on the ATS to test both the electrical portion of the generator and the Automatic Transfer Switch mechanism?

If yes, how often would you recommend running this test ?

Personally I do not do this. To make it an equipment safe test you need to first shut off high draw equipment (A/C, pool, water heater, etc), computers not on UPS, etc. These do not like the shock of a sudden loss of utility. It's one thing to have it happen occasionally but a routine test creates risk of breakage. If you home is on UPS that's another story but mine is not so I do not create shock loss conditions. The system has never failed to properly generate required power.

answer 2
Doesn't look like anyone answered the question of how often to load test the Generac units.

Working in an industry where we perform maintenance on backup generators all the time, we schedule these types of tests based on how critical the load is. In my house, I'm testing my 20KW unit once per quarter. We have several children and can't afford for the unit to not work when we need it.

I don't think there is a hard and fast answer to the question. The city building inspector came by to look over the finished install and he recommended load testing it once per month. There's something to be said for reliability of these units, and I feel like Generac has a good product so once per month seemed more than necessary. But if that puts your mind at ease, it's a simple test to perform.

I know it's an old question, but wanted to post an answer in case anyone was still looking for one.

answer 3
Like yourself, I want to be able to disaster test the generator.

After speaking with my professional installer, I determined that the best way for me to simulate a loss of utility power was to kill the utility power by opening the 200 amp breaker at the top of the Transfer Switch.

By opening the breaker I interrupt the utility power to my house,

As soon of the utility power is interrupted the generator will start. It will take about 30 seconds for the generator to come up to speed. At this point will will hear a chunking sound from the transfer switch as the internal power relay is thrown.

After this sound your house power will be running from the generator.

I would test for at least 15 minutes (to properly exercise the generator). To complete the test, close the 200 amp breaker in the transfer switch to simulate the return of utility power. The generator will run for a few minutes after utility power has been returned and then the generator will turn off.

You have then successfully battle tested the generator.

The 20kW automatic standby generator is designed to test itself weekly for 12 minutes when installed properly; this exercises the engine and produces electrical output. During the exercise time, you will not see a transfer of power, but the unit is still producing electricity. If you would like to simulate a power outage situation, you will want to contact your installing electrician, as they will be able to provide you safe instructions on how to simulate an outage. Another way to test the system is with our Advanced Wireless Remote Monitor, which will allow you to run the generator and transfer function while you still have utility present.

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-supp...

Unfortunately, we are unable to provide a life expectancy for a battery produced by an alternative manufacturer. Please note that we do not manufacture batteries for our automatic standby generators, and these items would need to be purchased separately. However, please note that Generac’s 20kw Guardian Series automatic standby generator, model number 6730, features a “Smart Charger” battery charger. This feature is integrated into the control panel module in all models, and helps to ensure the unit’s output charging levels are safe and continuously optimized to promote maximum battery life, whether the unit is running on either utility or generator power. Lastly, if you would like to inquire about the life expectancy of a particular battery, we would recommend contacting the company that produces the one that you have chosen. If there are any additional questions that we can answer for you regarding our own products, however, please do not hesitate to contact us directly at 888-GENERAC (436-3722).

We are sorry to learn of the issues that you are experiencing with setting your unit's exercise time. Please note that the desired exercise time and current date/time, need to be set appropriately in the unit's control panel for the unit to run at a desired time on a weekly basis. If the current date and time is not appropriately set in the unit's control panel, the unit will in fact exercise at an alternative time. Please also note that exercise times can be verified in the unit's Run Log. Directions for setting the clock and exercise time for your product, as well as checking its run log, is detailed in the unit’s owner’s manual. As the document alludes, when the unit is in the OFF position, you can check and set the unit's current date and time by first pressing ESC, scrolling until SUB MENUS is blinking, and pressing ENTER. Then scroll until EDIT is blinking, and press ENTER again. Lastly, scroll until CURRENT DATE/TIME is blinking, press ENTER, and continue the steps to appropriately set the time and date. If you are able to verify that all settings are appropriately set, and issues persist, we would then recommend contacting an independent authorized service provider in your local area to diagnose your unit's issues.

The current models of automatic standby generators will have LED indicator lights on the side compartment of the generator. The yellow LED light will indicate that maintenance is needed. A yellow light on its own will not cause the unit to not start or run, but the generator control panel should be checked to determine the maintenance needed. The other lights that could be lit include a green or a red LED. A green LED light will indicate that the unit is in AUTO mode and is ready to run, or is running properly during a utility outage. The red LED will indicate either that the unit is switched to OFF or that there is an alarm detected. If red LED is present, we recommend checking the generator’s control panel, as it will describe the type of maintenance needed, or the alarm present. This information can be found in the owner’s manual as well. You can find a copy of the owner’s manual online by searching the model or serial number of the unit here: http://www.generac.com/service-supp....
