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.
