I'm not an electronic mathematical genius, so bear with my thinking.
Keep in mind if that 80%-90% only refers to the 60%-70% of the power your battery has to offer(before you discharge too low), that the loss(of the usable battery power) is actually very substantial.
80%(inverter) of 20%(usable flooded battery). I would guess that means that 400 rated "usable" amps(printed on the battery), would result in 64 or so truly usable amps instead of the 80 amps you'd expect to use without the inverter which could be critical to the intended usage.
I guess what I'm saying is that unless there's a real worthwhile advantage to run off of AC, why not run off the DC(and save that extra money for a few more batteries at that)?
I say batteries, batteries and more batteries, to the point that no one battery should ever be expected to be taxed too much . . . but that's just my un-educated thinking.

George,
I believe most converters/ Inverters are about 80% to 90% efficient. My Sensata is rated at 88%.

Hi Eric
How much power is lost due to the conversion. Is it appreciable or negligible?
For example, if I had the choice between running a certain item off of DC or off
of AC , would my battery bank last a lot longer off DC?
Thanks George

What do you want to know? There are inverters available in many regular retail outlets that will convert 12VDC to 120VAC, ranging from 150 to 500 watts. Sine wave AC output is better for electronics. Anything else?
Fair winds,
Eric
