Will this be sufficient to run my equipment? 50ah Lithium/inverter

[wingnut771]

why the crop?
sure i did not put a question mark , anybody with a brain can see it's a question

I used 12V because you used 12V.

Hmm. I guess watt/hour would be a power rate.

1 watt/hour =



Useful for describing Eskom at the moment... -500 MW/day

You seriously need to go back and read my earlier posts again. Your refusal to learn is causing you to make a fool of yourself.

I know this is the internet and people love arguing on the internet, but damn man. Go do an electrical course and find out for yourself you clearly don't want to hear and understand the knowledgeable people on the forum.

Watthours is the better unit of measure for capacity (because it contains all the info) than amphours because without knowing the voltage you're up the creek without a paddle.

Putting amphours on the label is a legacy from the olden days. They should all put watthours instead.

They express in kwh or wh because people know those terms as that is what eskom and most utilities around the world uses to bill them

So watthours is just the same **** again as with the ah

640w for an hour

Is the same as 320wh for2 hours

Is the same as 160wh for 4 hours

In the end you consume 640w

FTFY

No. You still haven't learnt

In the hope you might have an ounce of teachability left, your above statement is impossible / makes no sense.

What does kw stand for

ie eskom charger you for what? kw per hour

kettle example 2000w
if you leave it on for an hour you would burn 2000w ie 2kwh because you used it for a whole hour
if you leave it on for 5 min it would burn 2000w but on avg it used 0.166kwh

the kettle did not suddenly use 166watt peak load because you left in on for a short while

wh and kwh is just an expression/measurement explaining how many watts you burned over an hour

should have paid attention in school

kW = kilowatt which is a thousand watts
Eskom charges by the kilowatt hour. I don't know how to say this in a way that you'll take it onboard, the concept of kw per hour doesn't exist, or has no intelligible meaning.

Your kettle example is close. You are correct that a 2000W kettle would use 2kWh if left on for an hour. 5 mins of use would indeed be 0.166kWh (but not on average).

Watts is a measure of power, it cannot be used or, as you put it, burned over an hour. The unit of energy you're looking for is watt-hour. Watt refers to the now, to instantaneous consumption.

You are correct, you should have paid attention.

It is basic math a wh

Is a means of expressing the average usage over an hour

ie if you ise a tv of a 100w for 30 minutes and 2 lights halogen downlights 50w for the next 30 minutes while reading

You consumed 100watt over that hour ie your average usage was 100wh

Now if you do that for 6.4 hours what was your usage per hour?

What was the total watts consumed?

Did you pull 640wh?

But it wasn't an hour

Wh is a means of expressing how much watts you can pull for an hour or have used over an hour

This is basic math

Not rocket science

Seems the 30% Math'rs are out in force

No. It means total used in any given time. It is like saying I travelled 120km - it says nothing about the time I took to do so

ie if you ise a tv of a 100w for 30 minutes and 2 lights halogen downlights 50w for the next 30 minutes while reading

You consumed 100watt over that hour ie your average usage was 100wh

No. You used 100Wh. You average use also happened to be 100W.

Now if you do that for 6.4 hours what was your usage per hour?

Usage per hour would remain 100Wh

What was the total watts consumed?

This is an incoherent question. There is no concept of "total watts". If I travel to Durban at an average speed of 100km/h what was the total speed at which I travelled?

Did you pull 640wh?

Yes

But it wasn't an hour

No. But as mentioned above the time in which the energy was used is irrelevant

Wh is a means of expressing how much watts you can pull for an hour or have used over an hour

No, it is a measure of how much energy one has used over any given time.

if i have to use your terminology
If i use 160w for 4 hrs

I would have to say i used
160w4h

Can the OP please lock the thread ... it's on a railway track in Turkey

It's not my terminology. I didn't invent the terminology of physics.

And no, if you used 160W constantly for 4 hours you would simply say you used 640Wh.
