Ampere/hour battery rating.

Hello !

Didn't even know there was another section hahaha.

If it is 12V and 100AH that is then 1200WH or 1.2KWH

Then if

24 V and 100AH that is then 2400WH or 2.4KWH

Is that correct ?

That is correct -
Battery in parallel - voltage will be added , amp hour stays the same
In series - voltage stays constant , amp hours is added up

2 batteries in Series = ( 2x12v) x 100Amphr = 2 400Whr

2 in Parallel - = 12v x ( 2 x 100Amphr) = 2 400whr

As a quick rule I just use a 100Amphr battery using only 30% will give me 360w usable energy - If the client wants to run a 1 Kw load for 2 hours then I say he needs 2Kw of energy divide by 360W = 6 Batteries - The configuration of batteries to suit the inverter voltage all works out the same , The bucket of water is still the same size.

Hmmm ..... Regarding series and parallel batteries, I think the above 2 statements are the wrong way round.

You are correct did an edit on previous post- Still confusing myself even with coffee and cigs

Awesome ! That is how I have done it and always understood it but had to make sure as the above stuff has me questioning my self. Albeit I did read it quick but still.

Appreciate it as always

I like your rule of thumb for the 100AH and 30%.
