My Generator Study

What I'm interested in, is the noise this genie is going to make.

The manual states this:

Now this seems to be a standard convention for the noise level. I found this image on Wikipedia:

Atlas_Copco_XAHS_347-pic7-Max._sound_power_level.jpeg

https://en.m.wikipedia.org/wiki/Sound_power

When Honda specifies their genie noise level they for e.g. the EU22i state "Operating Noise Level @ 7m (dB(A)) - LwA 91db(A)"

Is the Honda and Ryobi convention for noise level the same?
 
The RG-2250i is loud. You can't stand next to it for prolonged periods because you'd probably damage your hearing.

I wonder how the sound level of the RG-2000i compares to the RG-2250i.

What would happen if I earthed my generator with a copper pipe in my garden, then backfed into my home using a 10A extension cable (suicide cable - two male ends) connected to one of my house plug outlets?

I don't understand how this could be a problem.
I thought the earth grounding was there only to protect against lighting strikes. If there are two separate grounds installed (one on my genie and the other on my DB), how is that a problem?

The earthing is also there to prevent electrocution by means of an Earth-leakage circuit breaker (ELCB).

Wiring a transfer switch into the DB keeps the earth leakage inline and prevents accidental death.
Killing someone by deliberately ignoring electrical regulations is a sure way to land in trouble. They're not called suicide cables for nothing.

Have you tried the "plywood noise deflection" trick mentioned in the earlier vid?

I'm also looking at one of the Ryobi inverter gennies, but the idea of the noise bothers me already! Could one not put a pool-pump cover over it, modded with extra vents?
 
The ryobi 6900K is still running fine after 5 years.

Had to change the spark plug and oil a few times. Mostly less than 50% load.

It has run at 80% load a few times.

"I have power meter that shows load"
 
My RG-7900K has also been serving me well for about 5 years now. Only problem I've had is the plastic/rubber fuel tube between the tank and the carburetor goes hard from the fuel every so often which leads to spilling, and then needs replacing. Other than that I've had to replace the spark plug as well... Couldn't find the same brand, but went to a gardening equipment repair shop and they suggested that most generators of this size use the same generic specs, so I got a similar replacement and it works like a charm. Overall great generator, very pleased. Bit loud, but that's pretty much standard for these types of units. Going to try the plywood trick

I've just gotten use to the the noise.
I don't want to try reducing the noise levels by obstructing the air intake or the exhaust.
That will reduce the efficiency or damage the unit.

If there was a way to reduce the noise efficiently the design engineers who built the thing would have.
Do you think they really want to sell a noisy product?
 
Can this Ryobi RG2250i open frame inverter generator run a normal full sized new Hisense fridge/freezer combo, or rather start it?

Stood next to a Ryobi inverter generator suite case model today with a load depending noise level adjustment capability, and it wasn't too bad regarding the <95 db spec, and this RG2250i is rated the same db noise level, but does it run more like a normal 4 stroke, or not?

Any info would be appreciated. Looking at a second hand one, in prime condition it seems.

It should be able to handle that, at the highest most fridges will peak below the 1500W mark, so anything rated for 2000W should be fine.

Should be yes, but put it on first, highest load goes on first

I've got the slightly bigger RG2600i and it can handle my LG fridge freezer with ease. I measured the power requirement for my fridge and it was below 300w iirc.

Have to warn you though - rated at < 96dB(A) it's a noisy bugger.

The peak power?

The generator doesn't even burp when it kicks on. That's an older LG side by side door with ice-maker though - I can't speak for his Hisense.

My house uses less than 1000w during load shedding with the major appliances switched off.

My house uses that before load shedding :-).

We rely on some high rated items like microwave, kettle, the oven, iron, and of course geysers. Even the water pump uses 750w but we switch to mains water during loadshedding.

Ah the water pump will do it.
