Today I managed to complete the my monitor box. Here are some pictures of it:
The new box has at the top, the cigarette socket splitter, the charge controller, then the ammeter and voltmeter.
The ammeter is showing -0.01A because of the draw from the charge controller. It is just about dark here so the panels aren't giving out anything.
The overall cost of this box was minimal, costing just a few pounds for the wood. The paint was found lying around at my Grandads house and so did the screws holding it together.
I will be adding a page to my site soon to show the building of this and the solar panel stand and battery box (Which I am still working on).
Suggestions and comments welcome as always :-)
