What size inverter
I would like to know what size inverter would be required to run an
electric chain saw that uses 120 volts and 10 amps. I have some trees down in the woods that I need to cut up. I can get the tractor to them and would like to know what size inverter ( how many watts) do I need to run the saw. Thanks for any info Herb |

What size inverter
volts times amps equals watts.
120 x 10 = 1200. Larger inverter than that may be needed. Keep the 12 volt cables as fat, and as short as possible. Run more 110 volt AC power cord if you need to. Christopher A.

Thanks for any info Herb Somewhere between 1600-2000 watts should do it(that includes a 30% safety margin). Frankly though, for what that rig would cost and at the risk of destroying the electric motor or both, you might be better served spending the money for a used gas power at a pawn shop. Just my opinion because I get a sense this is not a one time deal. -- Digger Bob O'Dell |

But, starting up under no-load should be so short a time that the inverter should be able to handle a 1-second surge. They are always rated for both peak and steady-state load, and a 1200 watt unit should have at least a 10% overload factor that will get the chain saw running easily as long as it is under a no-load start-up. Now, if the saw binds, you could easily go over the 10 amps / 1200 watts for several seconds. Most likely, the invertor will not blow up, but will either shut down or blow a fuse. |

It may turn out, that the gas saw is cheaper than the inverter.
Do you have a friend, who has a gas saw, or gas generator? Christopher A. Young Learn more about Jesus www.lds.org .. "Digger" wrote in message ...

What size inverter
Most inverters have a dual rating, run watts and startup surge.

I agree with the above. The start-up current on a chainsaw with no load isn't going to be that significant and it only lasts a fraction of a second. The 10 amps is likely the draw with a heavy cutting load. A 1200 Watt inverter will likely be sufficient. |

My 500 watt Redi Line stopped working. I havn't the heart to pitch it out. I
conacted the company for repair estimate. I bought it used in 1985 or so, and it's probably antique. But, I can't bring myself to throw it away, or scrap it for the copper. Christopher A.

When people use the term inverter today for this kind of application I think few people would equate that with a motor-generator set that was common 50 years ago. Solidstate inverter technology has been around a long time and clearly is what is suited to the application in question. Call it cheap if you like, but it works, is proven and reliable. I sure wouldn't buy a heavy, bulky genset to run a chainsaw when I could buy a small light solidstate inverter. When I pulled up a pic of one of these Redi-Line things I had a good laugh. |

I wasn't suggesting that the OP go out and buy a Redi-Line, I was mainly replying to the surge comment(s). Those are the only 2 inverters that I've ever used. If those inverters that look like car amps work like you say they do, then good. I'd still put my Redi-Line up against any of them AFA, performance, reliability, and longevity. |

I've had an "el cheapo", 1200/2400 inverter in my work van since 2006. I use it every day to charge cordless batteries, and to power all the small power tools I use albeit for short periods of time. These include angle grinder, sawzall, circular saw, 1/2" angle drill and pistol drill. For $100 the Op certainly could get something adequate to power his small chain saw. |

If that's big enough, you still need a couple thousand rpm. Greg You don't want to have the tractor stuck in the woods with a dead battery. When I was looking into them to power my furnace and some lights from an inverter in case of a power outage, the biggest issue was my car alternator. It's the stock 100 amps, but I still don't know what engine rpm that's based on. A tractor probably has a lower amp alternator. That's the weak spot. You're not going to run a tool long on a single battery without the alternator going. 10 amps is a pretty heavy draw on a battery. Anyway, I decided hooking up a small gas space heater was easier and more cost efficient. There's some power loss with inverters, and they need heavy wiring and lugs.. Best place to get first hand advice on them is RV and contractor forums. I noticed some contractors use them to run power tools at job sites. Those are probably mostly hooked to pickup trucks with 100 amp or better alternators. I'm with those who say get a small gas generator or a gas saw. But if you can pick up a 2000W inverter cheap, give it a go. --Vic |

Jesus won't have you for a sunbeam if you tell lies. :-) Your battery won't last long so leave the engine running. , There is a possibility of overloading the alternator too.

Jesus won't have you for a sunbeam if you tell lies. :-) Your battery won't last long so leave the engine running. , There is a possibility of overloading the alternator too. Really you need a gas engine chain saw. And they are not that expensive an 18" 42cc chansaw can be had for less than U$125. And with your level of use, and proper care, it could last you the rest of your life. |
