I labeled (curse of owning a label maker), loomed and taped everything. The distribution box is just a terminal strip used to breakout the two 12 v circuits from the inverter. It replaces wire nuts.
This is the back of a volt meter. The round thing next to it is a switch to turn off the red glow at night.
The meter is supplied from thais fuse box. The box gets power in from two 12 v batteries on the tongue. The converter is supplied from this fuse box which also collects power from the solar panel
and from the hitch harness.
The buzz is still there in the inverter despite shellacking the transformer and tightening everything up. It may be a little tiny bit less annoying but i'm probably just fooling myself.
We have plenty of battery
to run the lights
and fan, so I'm just going to turn off the ac at night and fall
asleep to the sound of the night critters.
