UPS battery Back time = no.of Batteries * Ah of the Battery /
output KVA * 130 ? what is the 130 means ? can any one help?
because all are using this formula how its came 130?

Answer Posted / k.prakashchandra

Ah*voltage /1000=stored energy in Kwh = back up time in
hours * load in KW. Here instead of load, rating of
inverter is given in Kva. So with load at 65% 0f inverter
rating or at 65% of stored energy, the above formula nearly
holds good
