you wont get any joy using D cells,they dont have the capacity to drive an
inverter for more than a few minutes,thats why things like electric fences
use sealed lead acid batteries...besides which; imagine the cost of
replacement!

Subject: [EE]: Safety of 12V dc to 110v ac using D cells

drive

safe

argument?
