Solar Inverter circuit gives Alternating Current (AC) output from battery Power source, but the battery requires constant DC power supply to get charge, so the every inverter circuit contains Rectifier &battery charger controller segment. 

Solar inverter circuit constructed with few different stages.

1. Solar panel
2. Regulator / Battery chagerg
3. Inverter Circuit (Switching Pulse Oscillator)
4. Step Up transformer (220V/AC Output stage)
