need 24 volt applinaces [RE-wrenches]

I've become a believer in using small, portable inverters for cabin 
systems.  If these systems have small loads, such as CF lighting, 
music or a small TV even, a portable type inverter is usually adequate.

The advantage of 120 volts over 12 is huge.  Instead of wiring with 
#10 copper, #14 is adequate.  120 V CF lights are cheap compared to 
12 or 24 VDC.  Longer runs and 3 way switches work fine, without 
dimming of the lights.  Blenders, coffee grinders, weed whips, etc 
are (of course) readily available for 120 VAC.

A system with 5, 13 W CF lights will only pull 65 watts.  If a 250 
watt inverter is used, there is still 175  watts left over for 
whatever.  A small array and a couple of L-16 batteries would not 
support much more for long.

Small inverters may have a low, no load draw, so the inverter can be 
left on.  Lights come on instantly and Nicad loads can be 
charged.  Many Nicad batteries will charge on mod sine ok, or if a 
true sine  Exeltech is used, DeWalts, etc can be charged.   It is 
more appropriate than using a DR Series or equivalent machine which 
costs more, buzzes and uses more power to stay on, and may require 
two lights to be switched on to bring it out of idle.
