Heavy Loads
« on: November 02, 2004, 08:16:28 AM »
How do you guys use power tools? Do you have seperate battery banks, connected in paralel or something?


   Im curious for a few reasons.


 Ive read that some types of circuts should not be run from batteries, even if using an inverter.


  So lets say a heat gun.


   or a drill press.


   or heavy-duty electro de-magnatiser for security (giant coil, wipes disks DEAD)


    These are all slightly differant in wiring, thats why i picked them.


    What i know for sure, is i would need a HUGE battery to run my grinder or drill press. How long it would work, i dont know.

Alternate energy pretty much means alternate lifestyle.  You find new ways to do things differently or do without.  Running off batteries is not a way to save money.  A drill press can be retrofitted with a DC motor, compressors can run on gasoline motors, and you can demagnetize magnetic media with just a magnet.  Figure the average battery is good for a one kilowatt hour and then count up your loads.

We run the heat guns and $40 HF drill press, and 1x30" sander on a giant 35 pound 1200w inverter, and 2 T-105s. It makes you learn to do it fast, not leave it run looking for the next piece, and don't expect to use it for more than a couple (as in 3 or 4) minutes, or you will go without for a day or 2 (80w PV, no back-up).


More like a no choice but the..., so we will have to use it.


The better or normal inverters will go to low battery shutdown even with the 2 T-105s. Then reset then shutdown... but never turn what should turn. The 1200w monster decided to leave out those pesky low voltage and over power shutdowns.


Other things (well pump, lathe, another drill press, 'dremmel', etc) use air, but the tank is 250 yards away (1.5" line), so they tend to be underpowered for some things.

So basically, i should be thinking air-tank for tools and batteries for appliances/lights?


   I can see this being a little more challenging then i had anticipated. Good! :D


   + more factor.... Im trying to keep everything... fairly mobile. As in, i dont want to run heavy, fixed lines around for air or lets say, bands for fixed tools transmissions.


    So where does one purchase a 1200w inverter?


 It kinda seems like VERY few people in my city have or want an knowledge about A.E. or its products.

Hey! this may not fit your application as i dont know a bunch about inverters, escept i do use one. Im off the grid and rely on a 1000 w honda generator with 900 w continuous. Some of the power tools i use ive gotta give them a spin before applying power as the starting surge will  overload the machine. Ive not tryed this with my inverter but it may bring more lite on your situation.....z

The spin helps a lot.


The inverter is a TrippLite PV1200 or PW1200 or something. I think it retails for $600-ish!  I got mine at a pawn shop for $40, brand new, 1 dent, no box, no cables. Don't think they even knew what it was. Somebodies Y2K stuff I figure. There are other brands for $150-250, Vector, Statpower/Portawatz, etc.  They would be a lot easier to move around!


It may have an overload and under voltage shut down. But it hasn't done it yet. It does have 4x30a fuses.
