what invertor do i need

Hi,

I need some advise about inverter that i will need to do a job ,
well i need to make a trip for away from the city where there is no electricity and will be grinding iron with an electric grinder .

Now there is no electricity there and wondering if an inverter will help me do the job,12v to 115 volt invertor
I think the grinder is 1500 watt or something , what kind of invertor will i need or what can i use to get the proper electricity that i need

You will need one that outputs 1500 MAX continuous. Most companies advertise their inverters with surge capacity MAX rating.

Keep battery drain in mind....

I recently went through a similar exercise for my girlfiend's 1250W electric chainsaw.
Its ROT for sizing was a factor of ~1.5 - ie - I need a 1250W x 1.5 = 1900W capability, hence (say) a 2kW rated inverter (continuous 2kW; ie, typically 4kW "max" or peak rating.

But ignoring that multiplication factor, the 1250W would have meant a 1500W (3000W peak/max/surge) inverter.
At 1250W the inverter would be consuming something like 125 Amps - that's almost the same as my "reduction" starter motor or about 1/2 of my old starter motor.


I ended up buying a 2.5kW petrol generator off eBay for ~$200 instead. Hence I have a reserve time of 11 hours (ie, a genny tank of petrol) instead of maybe 10-30 minutes on my (auxilliary!!) car battery. The genny even has an 8A battery charger (ie, it's a spare alternator).


Ratings may be different over there, but in Australia inverters etc are generally advertised with their normal power rating, not their peak or surge value - we have good consumer protection LOL! (Surge is typically double normal power anyhow - just as 'music' or 'peak' to RMS power once was... LOL.)
