Hi,
I'm looking to buy a portable generator to use on my allotment but have no idea on what I should be looking for power wise. It will need to power circular saw, drill and a 110 volt angle grinder which will run off the transformer. Looking at a few on ebay with a power rating of 2300 kva but not sure how these power ratings work.
Any advise welcome.
Cheers
Spooch

This absolutely cracks me up, I mean no disrespect as I have chickens and a vegetable garden.
However who would of thought that the original LC hooligans the two stroke tearaways the Simpson bandit paddock jacket wearing LC jonnies would be asking about generator advice for their allotment. I sometimes look in the mirror and wonder what the hell happened .
Good luck with the advice

Think your stated rating is incorrect
Watts is the same as vs and the k is x 1000
So most likely it's 2.3kva or 2300va so roughly 10a

Good luck with the advice To be honest as I was writing it I was thinking "God I sound old" but I guess if your lucky we do actually get to be old but only in body not in spirit. Pretty sure we are all still 18 on the inside which is what counts. Thing about having an allotment is you get to play on tractors !! Also keep chickens, best and most entertaining pets I've ever had, eggs are a bonus. |

Generator for allotment seems extravagant to me unless your up there all day-maybe!
Generator maybe portable but I just sold one but still weighed 29kg I couldn't carry it far.
You can get All the tools you list battery powered
18 volt Makita just get 2 batteries other makes available

An angle grinder at an allotment? Got some rough edged spuds? Seriously battery tools make more sense to me too, easily portable and take 'em home and use them in the garage too!
Alex
now I want an allotment...

You can get All the tools you list battery powered 18 volt Makita just get 2 batteries other makes available I already have the tools I need so to purchase battery powered ones would set me back a lot more than a generator. Was thinking generator as so far I have found Half a tractor (seriuosly, found it in the middle of a bramble bush along with a 3000ltr water storage tank), a plough, drag, disk harrow, 15 lengths of 15ft cast iron piping about an inch thick and a huge amount of other scrap. Need a pretty powerful angle grinder to cut it all up so I can get it in my trailer and down to the scrap yard, don't think a battery grinder would do the job. Just need a genny powerful enough to power the grinder. |

Hoe (pun intended) big is this fecking allotment? Ones here are maybe 30ft square!! Sounds like you have an acre...  Alex |

Alex Allotment is about a 3rd of an acre, had a JCB on it a few months ago pulling up tree stumps, took the guy 3 hours to get them all out. He wanted £30 for his time AND diesel, gave him £40 as I would have felt guilty giving him £30. Still think it was a bit if a bargain. |

2300 kVA is a hell of a big jenny, 10,000 amps it will put out, one that size is probably powered by a V16 Cat engine and fit on the back of a 10 tonne truck, you could power a small village with that, I have a 1.5 kVa it will run a grinder 1100 watt no problems, or a fridge, not at the same time though, it delivers 6.5 amps
I doubt you will be using all of your tools at the same time all of the time, the grinder will be your worry, AFAIK UK voltage is 230V, using a step down transformer will cost you money to buy, much cheaper and easier to buy a 230V 5" grinder it will cut 1" water pipe no worries and you can plug it in at home too, a 7" you will be able to run with a 2kVA (8.6 Amps) if there is something a bit heavier to cut, although I'm guessing the grinder came off an industrial site that way no-one can borrow them to use at home, did i just say that, not insinuating anything here LOL
Lets assume you are using a single phase jenny, 1.5 kVA is 1500 VA where V is volts and A is current or Amps, so the Amperage you will get from a 1500 VA is 1500/230 = 6.52, all you have to do is add up the current draw of the appliances you want to use, all at the same time, multiply by 230 and that will give you the MINIMUM size of jenny you need, as Steve says factor in a safety margin and look at the continuous rating of the jenny not its peak rating

why not hire a beefy one from your local plant hire place or a petrol powered stihl saw, if you are only going to use it for a wee while?

Plus then I would also have it for anything I need powered up there. Crazy I know but that's the way it is. Plan B is to ask the guy who cut down the many tree's on the plot if I could use a plug socket from his shed for an hour or so (bottle of decent wine for his trouble) problem with that is that I would need a 75ft extension lead. |

Is this assumption correct?

How much current does the transformer draw would be the first question, I doubt it will run for free, you will always get some loss after you have plugged in the transformer as well
"In a transformer, AC current is supplied to the primary winding which sets up alternating magnetising flux. When this flux links with secondary winding, it produces induced emf in it. But some part of this flux also gets linked with other conducting parts like steel core or iron body or the transformer, which will result in induced emf in those parts, causing small circulating current in them. This current is called as eddy current. Due to these eddy currents, some energy will be dissipated in the form of heat." quoted from electricaleasy.com
The loss of efficiency on the copper winding is R*I*I where R is the resistance of the winding and I is the current, as you can see the loss is greater the more current is passed through as it is a multiple of the current squared
Oh and look for a pure sine wave jenny, they are more forgiving for tools, TV's and fridges, yamaha actually do a very good one
