DMerciful:
The higher the voltage, the lower the current required to deliver a specific power. This lower current reduces losses in form of heat so higher voltage systems are more efficient. Also ur battery has more longevity and better performance when the voltage is high and current low.
AH is more like the capacity of the batteries. See it like connecting two water tanks....whether series or parallel, the capacity of the two water tanks remain thesame. The relevance is a measure of the capacity for instance a 2000litres tank will last longer than a 1000litres tank given the same rate of consumption. So also a 200AH battery will last longer in of backup time than 100AH all things being equal

thanks a lot for the reply.

one last question, in your opinion, what type of sytem, in of volt rating would you consider to be a common and still efficient enough standard for a regular household supply? 12v? 24v? much higher?

hello gurus in the house.

this thread has been very informative. I have 2 questions.

1. please what is the relevance of volt (v) ratings of a system. for example, what is the difference i'll get from a 12v, 24v, 48v etc system?

2. what is the relevance of ampere hour (ah) ratings of batteries too. and then is it possible to increase it through battery arrangement, like it is possible with volt ratings?

thank you.

Hello gurus in the house,

please do i need medicals for a business visit visa? I want to be sure if it is needed, so i can just do it upfront when i travel for my biometrics. Thanks.
