sinbad, so it is then more efficient, the batteries will last longer then?

Your wiring requirements are lower. Don't see it making much difference to the batteries though?

So, if I am am drawing 400watts, would I get a longer usage from a 12v or 24v inverter.

Yes

 

[getafix33]

Yes

12 or 24?

 

[Sinbad]

12 or 24?

both, or possibly neither.

now that's confusing

now that's confusing

Yip - thats why i stopped asking

If I have an apple and an orange, what colour is my hat? That's why you got a confusing answer.

You're asking a question with irrelevant information, while leaving out the relevant information. So if we assume the 12V and 24V inverters have the same batteries driving them (ie 2x12 parallel or 2x12 series) then the answer is... still yes. There is some vague efficiency gain in using a 24V system, but a good 12V can have an efficiency within a fraction of a percent of the 24V. So all in all, it's a bit of a silly question. Next up - how long is a piece of string?

Twice the distance from the centre to the end

Is the string the same width all the way along?

@getafix

The way I understand it, a 12 volt battery draws more current than a 24V battery in order to meet a 400W load. A 24V battery will require half the current of a 12V to meet the same load.
Ohm's Law -> P = IV

The question I have is - Will using a 24V battery to power an inverter that requires a 12V battery damage the inverter?

If you put 24v on a 12v inverter you will blow it up

If you need 400w (or up to 700w) it is better to buy the 1200VA as you can then get away with using 1 Battery. If you buy the 2400VA, you need to buy 2 batteries, whether you need 400w or 1400W.

Doesnt matter, its still twice the distance.

Anybody heard of this company before? They sell an 12v UPS for led lighting. Would be great for emergency lighting for load shedding.

What sting??

--But-how-long-is-the-sting?--

15 minutes

15 minutes at what speed? I need to know.
