The solar monitor box:

Started and finished 20th August 2006:

Today I decided that my setup was way too "rough" and messy and that I wanted to do something about it. So I did.

I got a 0-15v meter, a 0-1A meter, my charge controller, a plastic box and got to work. I came up with what you see in the pictures below.

It has:

  • 1x 0-15v meter showing battery voltage
  • 1x 0-1A meter showing charge current from the panels
  • 1x switch for the backlights
  • 1x charge controller built into the box

    It took me 2 hours to drill and file out the holes for the meters and c/c to go into. The fitting and wiring took about an hour. The wires to both the battery and the solar panels come out seperate sides.

    The insides:

    The front:

    The front with the backlights on:

    The box came to an overall cost of about 20 ($40) (each meter was 8 ($16)).
