Tap votage is from the battery in 75-80% position so that
this volage is equal to the normal (float charge) voltage
of the battery set, when boost- charging is going on ,so
that DC supply voltage to the appliances is not as high as
boost voltage which could be 30 % more than the rated
volage of the battery set

Answer / prasanta kumar das

During boost charging total set of battery set on high
