As soon as global modernised too many technology comes and introduced about solution.Technology only depends on the requirement which not compensated by any mean, need only to know which requirements gives profit and popularity.One of the invention occurred by intelligent scientist is to store power by such mean , AC power can not be stored which generated by thermal, hydil and atomic resources, so they invented inverter to store a power by using electronics oscillation and acid battery by conversion in DC, then during shortage of supply power coming from govt grid , the inverter convert DC power to AC power and supply perfect voltage in home circuit.Tje Microtech inverter doing best job for that purpose.
