"Please i learn about digram& circut location UPS 1000W/12v."

If this means: "I need a circuit diagram for a UPS" then Google "ups circuit diagram".

"are also Transfirmor rewind"

I do not know what this means. Please reword the question.

If I understand you correctly, you are looking for a 1000W UPS circuit diagram, for 12 volt batteries.....I would just go an buy one as the designing, buildoing, testing would take a lot of time and more money......

Also, have you worked out the current on the 12 volt side, it is over 80 amps. That is some really heavy secondary winding!!!!

If I was designing a UPS for 1000W I would either work with at least 48 volts on the DC side....that gets the amps down to 20+....

So then you would need to have 4 x 12 volt batteries in series and a charging circuit to suit.

Do use special batteries that can accept a deep discharge, not normal car batteries, as they do not like being deep discharged and quickly become "Boat Anchors" if so abused.....
