Oh, I forgot to tell that my ultimate aim would be to sell power back to the mains and I have to be able to provide true sine wave 50HZ 220V, so 2000W would be very little to start with. Maybe there's a good idea out there only I missed it.

Thank you all for your explanation. My question would be this. Which one would you use in order to increase AC current and how? For instance I saw a SonnyBoy converter (using MOSFETS) that can supply 2000W converting 12V DC from a battery. Only it costs 3000USD. I would like to develop an extensible...

Hi there, Could any one explain me what MOSFET, HEXFET,IGBT,Current feedback Amplier and ChargePump-s are and how they can be used in UPS or power Supplies. I am interested in 220V AC 50Hz True sine wave.<p>Please, be prepared for very stupid questions later on.

Thank you all for your time.
Take care

Thank you guys for the messages. The key was given in the white LED message. 24 Hours no limit relatively cold light source. DC voltage can be as much as I want and current can be increased. My question was not how much I can get but which way to go. 220V DC converted to AC or 12V DC converted to tr...

Hi there, please excuse me for this long question in advance. I started with a solar panel experiment and got to a dead end. I can arrive up to getting 12V 30Amp from the panels and recharge the batteries. At this point what I cannot decide is whether to go on with increasing DC power up to 220V and...
