need 24 volt applinaces [RE-wrenches]

[Ian Woofenden, Home Power]

I agree with others who have suggested avoiding a 24 V system, and I 
live with one. I went with 24 V on RE guru Windy Dankoff's advice in 
the early 1980s. It was good advice then, before high-efficiency 
inverters were readily available, 48 V systems were almost unheard 
of, and PVs were much more expensive. Today's RE guru advice is 
usually to go with AC loads, unless we're talking about a very small 
system, in which case 12 VDC makes more sense.

That said, it's possible to find LED and CFL lighting in 24 V, as 
well as fridge/freezers, motors, and occasional audio stuff 
(especially from long-haul truck suppliers). But there are many 
things that you won't find in 24 VDC, which led us to use 12 VDC and 
120 VAC as well, leading to a very complicated system.

Today I recommend to almost all people that they decide between 12 
VDC and 120 VAC, and keep it simple.
