While the sun was shining brightly the other day and the solar panels were putting out peak power I charged up all my small devices and batteries.
Since I am not back to using just two golf cart batteries, I do not have as much usable energy as I did before. This means that when the sun shines, I have power to spare. The solar panels product 800 watts of power but my batteries are only rated at 216 AH. This equates to about 2500 watts, or about 1200 usable watts since batteries are considered discharged at 50% capacity.
At this rate my batteries top off quickly in the afternoon sun and the rest is wasted potential energy.
I plug in all my small battery chargers and devices to take advantage of this extra energy when the sun is shining.
I also connected up my Bedini motor to my badly sulfated golf cart batteries. I connected the four batteries up in two 6 volt pairs and then connected these in series to make a single 12 volt battery.
The Bedini motor is now happily working away at desulfating my older batteries.
Follow my daily progress on the path to self sufficiency on my off grid solar homestead.
