Cost of Running a Honda Generator or other

[Denis 362]

Recently on LINK there has been discussion about purchase cost of generators and I was just curious to know from those that have them as to running cost per Kwh. If known.

Me too! - it would be very useful to know.

I calculated the running costs based on the info stated in some recent posts -  I don't believe the results I got! - I figured, maybe someone got a decimal point wrong!

Cheers!

I found this on line the fuel consumption shown below should be close for any genset of same power out put as long as it has Gasoline Engine

 

All Honda power generators are equipped with its renowned 4 stroke engines, which have big advantages of durability and cleanness. HONDA offers wide range of 2 kVA to 8.5 kVA models, suitable for leisure, houses, office and construction.

Rated Output 2 kVA Consumption 1.15 litre / hour Tank Capacity 15 liters Engine GP160H1 Noise Level 65 dB Dry Weight 45 kg

Rated Output 2.8 kVA  Fuel Consumption (1/4) load : 1.8 liter/hour Tank Capacity 12.5 liters  Engine GX200T Noise Level (LWA) 86 (59 dB)  Dry Weight 57.5kg

Rated Output 3.2 kVA Consumption 2.0 litre / hour Tank Capacity 24 liters Engine GX270H Noise Level 97(70 dB) Dry Weight 71 kg

Rated Output 4 kVA Fuel Comsuption 2m3/ hours Tank Capacity Auto refueling Engine GE390 Noise Level 71 dB Dry Weight 79 kg

Rated Output 4 kVA Fuel Consumption 2.4 liter/hour  Tank Capacity 24 liters Engine GX340H1 Noise Level (LWA) 98(71 dB) Dry Weight 82.5 kg

Rated Output 5 kVA Consumption 2.7 liter/hour  Tank Capacity 24 liters Engine GX390H1 Noise Level (LWA) 99(72 dB) Dry Weight 87 kg

Rated Output 8 kVA Consumption 4.8 liter/hour Tank Capacity 31 liters Engine GX630H Noise Level (LWA) 99.3(72 dB) Dry Weight 162.3 kg (Includes battery)

All gasoline engine are not created equal, and fuel consumption can very widely according to engine design.

I have never seen a cost breakdown per unit used.  My Honda EU2000i will run somewhere between 3.4 to 8.1 hours on a US gallon of fuel depending on load.   With 6 hours being an average for a few lights, battery charger, this and that and a 8000 btu window unit.  You can figure 3 to 4 gallons a day average. For me without doing the exact math about $200 US a month running 24/7.  Hardly economical.

With the inverter controlled units some will buy the smaller 1000 watt units to run a 5000 btu window unit to save fuel.  I suspect that the smaller unit running at higher speeds to run the load will use about the same amount of fuel as the larger unit running at lower speed for the same loads.  I have nothing to support that conclusion only a guess.

Interesting!

Taking the first 2 machines on the above list;-

The ER2500CX spec says .... 2kVA, 1.15 lit/hr, so .575 lit/kWh, at A$1.30/lit, that's A$0.75/kWh ... surprisingly good, if it can be believed! ......  In comparison with about $0.30/kWh for mains power here in Oz.

The EU30i (which I thought was a rather nice machine) specs at ...1/4 load=.7kVA with 1.8 lit/hr. that's about 2.57 lit/kWh,  A$3.34/kWh! ......  [5x the ER2500CX figure]

Something's very wrong here! The 2 machines can't be that different!

If the EU30i used 1.8lit/hr at 2.8kVA, that would make more sense ..... A$0.84/kWh ... much better and comparable.

The odd real fact would be handy!!!!

A$1 = US$0.78 = 38PHP (approx)

 

ps. looking at all the machines on that list, it appears that about .6 to .7 lit/kWh is typical if these specs can be believed. That's a pretty respectable 2-3x mains power cost.

Thanks for that Jester.

Gives me something to work with.

The reason I ask is because my electricity consumption has doubled since I moved here.

I found one 'straggler' recently and disconnected them but I would like to hire/buy a generator and power the whole house for a couple of months whilst disconnecting myself from the grid.

The only thing I have changed is a refrigerator.

So either the New replacement refrigerator uses 3x the power of the old one OR there is someone else tapping my line.

And I am now using about 480 to 510 Kwh per month and it was half that before.

Maybe I need my own meter?

Here is a meter  does not cost too much

I will always be the reading of the electricity company meter that will be the one you are charged from

but with your own "slave" meter you can see if someone is tapping in

your "slave" meter and the electricity company meter should be close to the same
