2.1.7 Recommended Wire Gauge

  • Input PVIN(12V input) at J1– the recommended wire size is AWG #12, with the total length of wire less than 2 feet (1 foot input, 1 foot return).
  • Output J3(1V output) – the minimum recommended wire size is AWG #10, with the total length of wire less than 2 feet (1 foot output, 1 foot return). A thicker wire gauge can be required to minimize the voltage drop the wires.
