Denis 362 Posted July 18, 2017 Share Posted July 18, 2017 (edited) 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. Edited July 18, 2017 by Denis 1 Link to post Share on other sites

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.

Jester 3,610 Posted July 18, 2017 Share Posted July 18, 2017 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. 1 Link to post Share on other sites
Oz Jon 2,476 Posted July 18, 2017 Share Posted July 18, 2017 (edited) 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. Edited July 18, 2017 by Oz Jon Link to post Share on other sites

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? Edited July 18, 2017 by Denis 1 Link to post Share on other sites
Woolf 8,550 Posted July 18, 2017 Share Posted July 18, 2017 (edited) Here is a meter does not cost too much http://www.lazada.com.ph/kilowatt-hour-kwh-electric-meter-digital-1-phase-2-wire-lcd-580adin-rail-4167536.html?spm=a2o4l.search.0.0.TBgW5j&ff=1&boost=1 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 Edited July 18, 2017 by Woolf 2 Link to post Share on other sites
