My system looks a LOT like "JD's"!
I have a 3.5 trace invertor that has been giving me great service for over 15 years.First and only inversor I ever had.
I have a big house,lots of people,TVs,Fans,computers,and more.We have two refrigerators,one connected,the other not. most every thing in the house is connected to the invertor.(No ironing,toaster,micro wave,or washing machine when the invertor is in use please)
Not a big deal,sometimes "Pops" the breaker on the invertor if they are all used at the same time.
I started with 4 trogan batteries when I first moved here and was just renting.When we moved to our house a year later,I went to 8 batteries,the power was off for days at a time back then,so I went to 12.
Things have gotten much better in the last 2 years,so when the 12 batteries needed to be replaced,I went with just 4.
They give 12 to 16 hours,depending if the power is off at night when we are all sleeping,or during the day when everything is "ON".
I use only low energy floresent bulbs.
Lisa,I say a TRACE invertor,2.5 should do you ok,and four good batteries.
Doesn't much matter which brand,maintenence is the KEY to long life!
I think "JD's price estimate is low,better think about more like 25 K for the invertor,more if you want on that doesn't make your fans sound like a swarm of angry bees.
