  • How do I choose the input voltage?
    The choice of voltage ranging from 12v to 48v depends on the kva you are designing.
  • What MCU is featured in this schematic?
    The featured M.C.U are the Microchip PIC16F72A OR PIC16F876A.
  • At what voltage does the inverter shut down?
    The inverter shuts down at 10.5 V.
  • When does the beep start for low battery?
    The beep starts at 11 V for low battery conditions.
  • What is the delay before charging begins?
    There is a 10 SEC delay before charging.
  • Does the inverter include temperature protection?
    Yes, it includes a high temperature shut-down input.
  • Can I use this design without an H-bridge board?
    No, Step 3 specifically requires designing your H-bridge board.
  • What transformer size is recommended for testing?
