    • Provides the most pressure and air flow for power usage, vents will limit air flow anyways so higher air flow isn’t needed

    • Also is the thinnest at 10mm

  • Vent options:

    • McMaster 4236N15McMaster-Carr

    • smallest vent that still has good air flow, other companies also have vents with the same dimensions and ip rating

    • Bud IP67 Moisture Blocking Air Vent, M32*1.5, 1.22 Inches Dia., Black IPV-67321-B - Bud Industries

  • Made walls thinner to make enclosure lighter, reinforcing pattern on outside

• R2/3: Consolidated all three MPPT boards into one enclosure to minimize space, placed inside the rear of the frame underneath the MOCO

  • Two lids on the top and front for harnessing and LED visibility

  • However, much more difficult and not necessary due to more space from Daybreak shell

• R4: Changed to rectangular shape to simplify design and take advantage of space

  • However, too large and needs to be either printed in 3 parts

• R5: Changed to composite panels to avoid printing too many small parts together
