how to calculate Amp, 2 different Amp of batteries?

Example:

No. of Batteries = 2
Battery voltage = 12V
1st Battery rating = 17AH
2nd battery rating = 30AH

between parallel connection then output volt
12v
Amp?

Answer Posted / amd

As batteries connected parallel so resultant ratingis will be
17+30=47amphr
hence current will be as bellow
47amp for 1hr
23.5for 2hr

Is This Answer Correct ?    5 Yes 0 No

in a solar power plant,we are going to step up the voltage 350V to 33kv, and to 132kv GSS. i want to ask that if it is possible that 315v/33kv is not possible because we also use 315v/11kv. or it should be 415v/33kv? is it effects generation or losses?  the second question is-generation is depends on LV winding? or LV winding design for generation voltage?
