Yes WD, Generac is very well known for their brand of residential backup power units, you see and hear their advertising all the time.

They're looking for someone to develop the Construction & Industrial markets here in Ontario for the other range of their products.
They have a very interesting diverse range of products, but as I mentioned to Jim, they need to make some engine changes to be more accepted in the construction industry.
The product range they currently offer, looks to be marketed more to the homeowners and DIY market segments.

Here's a screenshot of their current line of products.

The common gripe was the fault code on the home back up systems. I'm not sure if this has been corrected but it was so proprietary that it was a even with the repair folks.
Something like John Deer equipment the code blinks and the farmer is stuck in the field for 3 days.
I understand there has to be a bit-but there's a limit also.

Morning Bill, Bart

 

[pepperj]

We have a Generac. Been in this house 9 years and it has kicked on I believe 3 times now. It did not let us down. We were especially grateful we had it when the tornadoes came through last year.

A back up system is worth it's weight in gold when the grid falls apart.
Query: Does your unit kick in once a week automatically to do a system check?

Common grip with folks off the grid-unit kicks in runs for up to 30 minutes because has to reach optimal temp. then the cool down-while not doing anything useful. Waste of fuel is the common gripe as that's 26 hrs a year of fuel being wasted-then again the manufactures don't care about little things like running expenses.

This is good information to know Jim.

We use to have similar issues with our 20, 38, 58 & 85kw silenced generator units from WN. The biggest problem as far as I'm concerned, is the manufacturing industry being compelled by law to make equipment Tier 4 air emission compliant generators. This is a major reason for fault codes being displayed on the Deep Sea digital control units. These generators are simply not run under enough load to burn of the carbon build-up within the engine, this results in a 'wet stack' power issue with the generator end. The generator sensors pic this up, create an error code and the units shut down until the system is serviced and rebooted by a factory trained representative.

Wet Stacking is a condition in diesel engines in which not all the fuel is burned and passes into the exhaust side of the turbocharger then into the exhaust system. The word "stacking" comes from the term “exhaust stack". An oily exhaust pipe is therefore a "wet stack". In diesel generators, wet stacking is usually caused by the diesel engine running with as little as 20% ~ 30% of its rated capacity. Fuel injector fouling will occur if operated for prolonged periods at low loads. It is detectable when there is a black ooze around exhaust pipe connections and turbocharger.

For non-emissions hardware engines, you will typically see continuous, black exhaust from the stack when under low load, indicating that not all the fuel is being burned. For emission hardware engines there is unfortunately no tell-tale black smoke, as the emission components will likely start plugging and the engine will shutdown. Damage to the components and/or the engine is possible. Low temperatures can also affect generator performance making low load operations even worse. Resulting in expensive engine repairs and equipment downtime. To keep your diesel engine-generator operating at peak performance it is advisable to provide no less than 30% running load at all times. In colder climates perhaps you should consider even more. This will keep the exhaust temperatures elevated which will activate and maintain the emission hardware.

It's all well and good for the homeowners to complain about, "fuel being wasted-then again the manufactures don't care about little things like running expenses." But from the point of view of an OEM and a sales rep the guidelines manufactures have to meet are very strict and we're all doing the best we can to build 'environmentally friendly' machines.

Yes, it does. I can't remember exactly, but I don't think it was that much fuel used last time the guy was out here. I think ours only runs for 15-20 min. And, like you said, when the power was out, it was worth every penny.

The latest bells and whistles is maintain the employment of "the system is serviced and rebooted by a factory trained representative"
This is why older is better, so anybody with oily hands can service the engine.

Mornin all!

 

[WannaDig3687]

Good morning, releventchair. I have been waiting to catch you on here. A couple years ago you helped me with information about a rifle my father-in-law gave MR WD. Well, he finally gave up information that he didn’t realize he forgot to mention verbally or in his letter. He probably still doesn’t know he had forgot to. It was an awkward moment, so I didn’t ask any more questions. Any way he blurted out that it was the 19th rifle that John Riddle built.

Good afternoon RC.

Ahoy! Cap'n!?

This one's for you!

Good afternoon WIF.

For the folks like Dave who hunt old farmsteads time to pick up a drone to track down those cellar holes and other forgotten former structures.

Good afternoon, people.

 

[Rookster]

Been off air today. Doctor yesterday. Chest cold or not enough rhum one. Going to find out here in a minute. Anyway got the ole shot in the buttie and a fog machine of some sort you deep breathe for about 15 minutes then the doc listens to your chest. Boy shes Purdy. Anyway it reminded me of the old days smoking the pipe. Great reading the conversation from all over the world. Well nearly. See y'all monyata.

 

[bill from lachine]

Good evening Rusty.

 

[bill from lachine]

Rook,

Good luck with the results of your tests. Hopefully some R&R will clear things up.

Thanks bill
The shot has helped as of today. Pollen is terrible this time of the fall.i guess the yard care got me this time. A mask is a must this time of year. Side note: the nurse that gave my shot was Purdy hot too.
