Your last generator Maintenance Run

[3930dave]

Thanks Dave!

I installed it 4 years ago after getting along with a 7.5 KW gas portable for many years. But I got tired of starting the generator, wheeling it from the barn to the house, and then plugging it in and throwing a transfer switch. It seemed most power failures were at night during snow and it is uphill from the barn to the house so I truly was pushing the generator uphill through the snow.

This one is a 40 KW with a 200 amp auto transfer switch. I went with the Asco commercial transfer switch over a "homeowner" grade because it allows more customization including allowing engine warm up delay between power loss and changeover to the generator. It also does an in-phase transfer back to commercial power 5 minutes after it returns and is stable.

40 KW is a bit of overkill but it was only a little more costly than the 30 KW model I considered and the 40 KW has a more efficient 3.3L Mitsu direct injected turbo diesel and uses a mechanical pump with governor but the engine controller has fine speed control over the governor to keep it very close to 60 hz spec. The only downside is loading it sufficiently, not a problem in the summertime with two central air units and a pair of electric water heaters plug the well pump but in winter I use a lot of space heaters for a load when exercising it. Far different than the former portable I used where I needed to shut pretty much everything else down when it was time to start the well pump to refill the pressure tanks.

This produces very clean power which is one of the first things I noticed after install. I am a ham radio operator and I installed commercial grade surge protectors at the breaker boxes for the house, barn, garage, and outbuilding and these also have an interference filter in them (RFI filter along with MOVs and gas discharge tubes). When running off the gas generator, I could hear the metal boxed suppressors "singing" along with the generator but now they are silent and this generator produces a beautiful sinewave on the scop. With the generator installed in the semi-basement part of the barn it is extremely quiet running at 1800 RPM and it can only be heard with the windows open. I should have installed it years ago, it has been well worth the cost and effort!

Wow ! Killer setup !

You've blended various technologies very well, and understand the MTCE needs of a relatively high capacity diesel - I'm sure it should give you excellent service for a long time.

Happy DXing , esp. when the grid is down !

Back-up 20KW Eaton (Generac) ran for @2 hours today due to a power outage. Inherent extended exercise other than the weekly 15 minute auto runs.

I had a 10kW Generac for 10 years and it never failed, but it was getting old and only had a 10 circuit transfer switch.

We are both getting older and decided that we wanted Hot water, Air conditioning, oven, cooktop and the garage/shop powered all at the same time (more or less). 2500 SF all electric house.

I upgraded to a 22kW Generac but now in the 6 months since install, the total run time including exercise has been 2 HOURS total.

So why did I upgrade

It's called "insurance". The more you spend on a generator, the less likely you are to have an outage.

During the extended power outages here my Honda EM 5000 powered the refrigerators at 4 single family homes plus modest lights and computer/cell chargers…

My then 95 year old neighbor was in charge of rolling it out and laying all the 10 gauge cords.

Originally it was just for my house but I was often away so he took over for my place, his place, his daughters place and we added the 100 year old widow lady next to his daughter…

The Honda has been zero trouble since I bought it new in 1985…

2 hours isn't long.... but if you have just got in the shower, before going to work..... nice to have the seamless transfer of power....

Murphy.... has many sides

The interview was about other things, but in a recent podcast, a guy who consults for resource companies, mostly in the USA, commented about considering "Do I really still need to be paying for this Sat-phone ?"... then, just a little afterwards the big recent AT&T outage happened....

I was thinking of your Honda as Vintage, then considered that your Gen Tech/Minder and neighbours would consider it only a Pup !

I live in the desert where the Santa Ana’s originate. We do experience significant wind during Santa Ana conditions, but nothing like coastal areas.
