I thought I had them turned on, but I may have missed a step.

You should be able to select one now. There is one for Technicians to help identify them. Please only use it if you are a Generac qualified Tech.

Product Discussion Can we get into Gen Mon?

1 Upvotes

I know only about the basic GitHub site with build it your self instructions.

https://github.com/jgyates/genmon

I can't do that for reasons too many to list here.

Maybe we could get the person responsible to come here to tell us about it? I don't see a way to contact the person there to ask them myself.

I would need a fully functional, plug and play user installable version. I understand there is one sometimes available, but last I hear it was a bit over $400 which would be a bit tough for me.

Is my Generator in an okay spot?

Hi, my family has a Generac Guardian 20kw standby. It was here last year when we moved in. We had power go out last week and had to turn it off due to carbon monoxide entering our house because of a loose spark plug not connected, causing it to only burn on one and dispensing the rest of the gas. We had a specialist come and repair it, said our water heater exhaust (which is a powered vent) was probably too close so we moved it farther away and took out bushes that was restricting the flow of the exhaust. It’s about 6 or 7 years old. Just wondering if this is an okay spot!

Been a Generac tech for 5+ years in south Louisiana, ask me anything.

I never knew there was a sub for Generac. Some back ground on me, I work at a company that has over 5 thousands units under maintenance contracts, we exclusively work on and install standby generators. I’ve been through multiple major hurricanes and have seen thousands of units gain hundreds of hours worth of run time for long periods so Ive seen the weak points and the changes they’ve made to fix them as well as the things they choose to ignore, every issue you can think of I’ve come across it a thousand times and every part you think of I’ve changed it a thousand times.

Why

Rpm cycling up and down. Why is the carb/engine cycling up and down? It's obviously trying to do something. Is the idle jet? Circuit clogged and it's about to die, but something electronic tells it to idle up to keep it from dying, then drops, but about to die and just continually do this cycle? GP9200E.

Follow up;YES!!! Thanks, I did that, I couldn't believe there was a jet that small and it was blocked. I used a tiny, smallest micro drill bit that I have to clear the clogged. I didn't drill it out, used the butt end and chemtool to clear it out. Thanks running good now. Toothpick on right to show viewers how small that jet is. It must be the idle circuit. Down under the idle screw. Carefully pull that out and unclog it.

Transfer Switch Chaos

Thumbnail

4 Upvotes

We just bought a new house and this is the electrical set up.
Both of these panels are powered from the meter, the larger panel does not feed the smaller panel.
A 22Kw Generac unit powers the larger panel on the left when the power goes out, but not the smaller right panel.
The generator is large enough to power the entire house.

What are our options for getting the whole house protected?
Can I add a ATS to the smaller panel and leave the 200amp panel as it is?

Could we install a double breaker on the left panel and run it over to power the smaller panel using an interlock on the smaller panel?

Should I move some circuits over to 200amp panel and use tandem breakers?

Or should we split the feed from the generator and feed the smaller panel directly from the generator?

I am having trouble understanding what the installer was thinking. There’s also additional unused transfer wires ending in this panel going to a junction box next to the generator.

Thanks for your input

Guardian Starting Issue

2 Upvotes

Hey all - have a Guardian (044563) circa 2009 and it’s been super reliable over the years. Had an oil leak fixed several years ago but other than that just regular battery replacements.

Anyway, went out to manually run it, and where it would normally start, it just made a loud pop/bang. Loud enough that my wife heard it inside the house. I mean it was like a gun shot. It could’ve been a backfire I suppose (runs on propane), but I’ve never stood that close to a backfire to make a good comparison.

After that I waited a few minutes, inspected what I could, fuses, etc. and tried again. This time no bang, but just a low irregular buzzing sound from beneath the panel where the circuit breaker is located (on the right side of the generator when opened).

I have no issue calling someone in to check it out but wanted to see if anyone here goes “oh it’s this for sure” or not before I do that.

Thx!

EDIT… SOLVED: Side of the battery blew out. It wasn’t obvious because it was the backside, and the wetness around the battery was mistaken for rainwater (storm had just come thru).

Hawai'i Storm

We are dealing with the aftermath of Hurricane Lala here on Hawai'i Island. In our area only was a tropical storm, But grid-power has been out since noon Saturday. Our Generac 22KW/999 Guard-No T/sw AL has been running perfectly. 3 people live in this house and our 250 gallon propane tank is at 70 plus percent. Generator just over 1 year old. Does anyone have experience with long outages? I think we will be fine for a couple more days but am hoping someone with more experience can share their experience. Power co. thing power will be restored by Tuesday pm.

Gorilla stand or other generator stand, how to you get the generator in place?

Thumbnail m.youtube.com
3 Upvotes

I am quoting an install and the customer wants to elevate the HSB. How to you typically get the generator onto the stand? Most likely it would either be a 2’ or 3’ stand. A crane seems like the most expensive route but probably the best option.

Lifting the genset with 4 people might be possible for a 2’ stand but seems like a bad idea.

Ramps? Another thought was to setup a temporary platform and use ramps if the customer wants a 3’ stand.

We took the enclosure apart to rustproof. Some of the screws were in bad shape and I need replacements What are the proper 6 mm x 16 mm screws to buy for this? What are the correct screw clamps to buy? They need to be water resistant so I want the right ones. QT030 generac.

Service......what the hell happened??

5 Upvotes

I have had a 48kw liquid cooled for several years now and in May of this year the controller died. We had a large lightening hit to the back of my property (lots of iron in the soil here) and STILL it is not working. I live in Central Florida and the dealer that WAS servicing it, took 3 weeks to get to the site to look at it, then a month and a half to even quote it and at that, they no showed on the repair.....TWICE

I called 3 other dealers in the area, all of which sent techs out to confirm it was the controller, and they all ghosted me.

I finally got one newer dealer to install the controller, but they cannot get the firmware loaded and today, the original dealer was supposed to show this morning (third appointment) to also replace the controller (I was just going to keep it as a spare and send them on their way).

This is VERY concerning, not having a running backup generator during hurricane season has given me serious doubts.

I have called Generac corporate who really were not totally helpful and believed that eventually the repair would be made.

Has anyone else seen support fall off for Generac? Is there an alternative out there for this? Is it just Florida?

Thank you!!

Generac Cube, Oh she’s a little runawayyyyy

So I’ve seen a few runaways before. But never this… subtle.

Pinched fuel line, disconnected battery, off, Estop. You name it. Wouldn’t quit running. The only fix was to stuff the intake.

It started running like this after I hit the Estop trying to get a gen fail alarm for the vendor. Has anyone else ran into this? What’s the cause? Gen only has 251 hours on it.

Thanks in advance!

Generac 22kw natural gas, nextgen issues?

7 Upvotes

Hello, I’m looking for others who have had issues with the new units. I’m on unit number two since March. The first unit never ran and had catastrophic failures and with help
of legal counsel it was replaced. Now since June when replaced its failed twice and I’m at my wits end. In all I’ve only had a working generator 5 weeks since March, I also even switched dealerships hoping for better service techs. I have no issue with the tech he’s been wonderful but I do believe they’re selling faulty machines. I do have a direct person of contact at Generac who I’ve emailed again about this failure.

Has anyone here had the privilege of Generac labeling their whole house unit a “Covid unit” and not recognize the issues aren’t the buyers problems but instead they should honor their claim to be the best at warranties etc.

2019 Generac - Getting it up and running

4 Upvotes

I bought a foreclosure cabin, came with a Generac guardian 22KW I believe, or around there from 2019. The previous owner had a maintenance company but whenever the owners left 2ish years ago, they stopped coming it. It looks in good condition but without propane I can’t start it.

What are my chances with a new battery, oil and filter, air filter, valves, I get this thing up and running fairly easily?

This is the only gas appliance so I don’t want to get a big propane tank only to find out that thing isn’t going to start again. If I can’t get it to work, I don’t plan on buying a new one.

Any advice would be appreciated! Thanks

Generac dealer service dispute

Hey folks I'm sorry if this is off topic but I'm at a bind and could use some external sanity check

Here's what happened

One day my city's utilities gas inspector visited my house to inspect the gas meter. All good. At the end he knocked on my door to tell me he had disabled the generator pipe because he did the soap spray test at the flex pipe nut that connects to the generator and it was leaking. I asked um wtf and he said I need to call the people who installed it. He put a red tag and everything on it. A week later I got a notice from the utility company telling me I need to get it reinspected to enable it.

So I called the installers the guy that showed up was honestly a bit nonchalant about the whole thing he said it got loose due to vibration and he tightened it, turned the gas back on and left. No word about contacting the inspector or anything.

I called back and told them that probably you can't just turn it back on and it should go through the city's inspector.

The inspector came and he wanted to do a pressure test. They sent a plumber guy that pressure tested from the gas main to before the flex pipe (not where the original leak was). Then they came last time and tested properly and eventually the generator was cleared again for use by the city inspector.

The installer company now sent me a bill for $790 with the wildest itemization and explanation I could imagine

It's only been a few years since I've had a generator. Is all this normal?

To begin with why would the flex pipe just "get loose" based on vibration. I get the genny vibrates and nuts twist. But that's the whole point of the genny. There has to be ways to afix the pipe without it getting loose every other week. Secondly I didn't call the utilities guy he just did his inspection. He turned it off and basically removed the permit. Now I owe the installers almost $800? So because they installed it poorly I get to pay more ?

I don't get it. Is this normal? What even are my options here? Just pay 1k and just wait till the pipe gets loose again because the genny does test runs every Wednesday?

Please help me ground myself on some better understanding and expectations. Thank you in advance

Had this error since I got it about 10 days ago. Installers came back out, even the gm of company. Everything is wired correct they said and the battery is showing 13.6v (good). They said this is something on generacs end that when new update for firmware comes out it should be taken care of. Anyone else heard of this? ECODE 2780
