Answer Posted / dinesh kumar sharma
dc voltage is necessary for l.t pannels was because dc is
free from harmonics as well as smooth, in dc voltage no
variations are there so controlling becomes easier.
no we can not use ups takes ac to charge battery store in
dc and than when ever supply cut off than battery going to
discharge voltage is converted into dc to ac one of the
example in case of computer
and also ups can be used for smaller duration so why we
use UPS
