Solar Mount Braket For RAK19003 & RAK19007 + Battery Tray

Battery Tray V2  (01/17/2026)

Adding an additional battery tray for better clearance. This is the battery tray that I would recommend using for the 5.9"x3.9"x2.8" junction box (second to last photo)

The smallest size that this bracket combo will fit inside is a 5.9"x3.9"x2.8" (last photo)

If you plan on adding other things like I did, I would recommend using a 7.9"x3.9"x2.8" or bigger junction box.

To mount the RAK19003 or RAK19007 you will use the M2.5x4 screws that come with the board.

You will need 8 M3x6 to attach the bracket to the junction box and the battery tray to the bracket.

The RAK bracket can be attached to mounting plate that comes with the junction box or without the mounting plate.

The battery tray hold battery that is bigger then 2.6"x1.25" (66mmx32mm) up to 4.6"x2.65" (118mmx68mm). In the photos I'm using a 10,000mAh battery, use a velcro strap or something similar to hold the battery to the tray.
