Good day! I am wondering how to make a solar power inverter. I know the inverter gives 20V and 10A, should I use capacitors with a charge pump (the losses from the capacitors will be big I guess)? Or should I use a step up transformer with a 5V to 0V ot 2.5V to -2.5V sin signal?

Can anyone explain the difference between these 2 approaches and why is 1 of them used for solar inverters?
