invertor question

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   We are about to Move to somewhere which Is off the grid and gets power VIA solar and wind.I own two invertors one at 110 and one at 240.As I own equipment that can be run at 110....ie decks and mixer...does it make any sense to use them at 110volts...will this be any less demanding on the batteries?

	Quite the opposite actually. The inverter (dc-ac conversion) efficiency would be roughly the same but the reverse is not the same. It's more efficient to ac-dc convert (as happens in all power supplies) from 230V AC than from 110V AC. Total efficiency increase is between 5% and 10%. Edited by Saturnus - 14 April 2011 at 4:24pm

	Are these cheapy inverters ? If so, you may get problems with turntables if they AC motors (e.g. most types of belt or idler drive) as the inverter o/p is gonna be pretty much square wave. I'd say to run these types of gear you'd need pure sine wave inverters (a good deal more expensive). But thats an educated guess - not based on experience.

	No not cheap at all..both pure sine wave from when we lived on a boat..

	Check E bay for APC Smart ups used and without batteries (Shipping weight ) It's a pure sine wave inverter They come in many different capacities if you look hard you can find them for $50 I have one in my workshop with 4 -12v car batteries as part of a solar experiment and I'm running my shop on this setup
	In my early years my favorite phrase was "If it's too loud your too old" Now I'm just too old
