combination two 200VA transformer connect to parallel for 400VA output with Pic 16f628a microcontroller modified sine wave..10pcs low ohm power mosfet, total power 800W at 12v 100ah- 500w at 12v 50ah battery.i am successfully my target for power up 500w - 800w equipment such power tools,jig saw,blender and rice cooker..look like very bulky and heavy but still far cheap than commercial inverter in market..total cost my inverter only RM 270.00 - USD 87.00...in malaysian power inverter very2 expensive in market total cost for 800w modified sine wave about RM 850.00 - USD 274.19! better build one coz electronic component,transformer,casing etc here very2 cheap in town..
