Manufacturer of this Power Jack PSWGT-300 Solar Grid Tie Inverter decided to scuff part numbers. Therefore sharing possible part numbers gathered from the wide web:
- U1 – might be atmega 328p microcontroller
- U2 – might be SG3525A PWM controller
- U4 – might be LT1013D operation amplifier
- U5 – LM3171 voltage regulator
- U6 – 78L05 voltage regulator 5volts
- Y1 – 16Mhz crystal osciliator
- D8, D7, D10, D9, D37, D39, D40, D38 – RHRP8120 8A hyperfast 1200V diodes
- Q1, Q2, Q7, Q6 – DC side n-ch mosfets STP75NF75A 75v 80A
- Q8, Q11, Q10, Q9 – AC side mosfets FB11N50A 500v
