Rapid response demands rapid inquiry for details -- May I assume that the spec you provide 220V 50 Hz 10A is the output your are trying to obtain? -- the question remains -- what DC voltage and current capacity do you have available? You may be asking for an off-the-shelf inverter from a camping supply house (although the 50Hz would indicate a non-North American application)

As usual, not enough info even to make a proper educated guess.....and we do not make such guesses about stuff that can easily kill people.....so be careful.

But just in case the DC supply is 12 volts, then have you worked out the battery power needed????

2.2 KW is the output power required. Assuming you build a device that manages 100% efficiency (which it will not of course, 50% is probably more accurate) then you will need a battery that can supply over 180 amps continuously!!!!

That is a very big battery....assuming that you want to supply this current for reasonably long periods.

If the efficiency of your converter is only 50%, then you will need around 360 amps at 12 volts.....

A normal car battery will only last a minute or so or slightly less at a guess connected to this converter......it will be similar to starting the engine in terms of amps...

Efficiency of converter at 50% is probably too low but 100% is too high of course, so the final need will be somewhere in between!!!

In your case, may I suggest that you go and find a conventional submarine that is not required and buy some of its batteries.......they will give you some days of output....once charged!

JBL Car Audio Amplifier GTI6000 with a 50hz signal, plus one competition Kinetik 2400 Powercell per 10 minutes of operation.

Look up "Inverter" instead of "Converter" on google or some other search engine.
