please send me a schematics concerning the the inverter 3 kw power

Dear ck923456
Hi
is your mean , single phase inverter? if yes, what is your desired frequency ? and what is your Supply voltage? is that collection of high power batteries? or it will supplied from power line?

hi
read this it may help you if you design single phase inverter

3KW on what input voltage?


Carefully pay attention on input voltage and amperage make calculations.

hello tpetar,
I thinkthe inverter/ups you proposed with 12v Batt.will be unable to charge the battery
properly as it requires at least 300 AH battery and it'll take 30 hours to charge.Will it not be possible to run it on 24 volts having battery capacity 100+100 AH to meet the the charging bit soon and moreover feeding the switching side with micro controller chip like pic16fxx to avoid the jungle.plz think about its possibility.regads

Of course, I also say to pay attention on input voltage and amperage.

For higher wattage better to use higher voltage to reduce amperage.
