The following picture is an update of the Solar Power Panel:
I have changed the way that I monitor the voltage and current drawn by my DC devices. I have added the 2 buss bars on the lower left. The positive buss bar is connected directly to the battery bank, The negative buss bar is connected to a 100A current shunt.
In the picture below shows the small DC current buss which show voltage and current thru it. I had to change this as the previous one used a shunt and did not show low currents very well. The current meter below is able to handle up to 10A.
