The first thing I needed to do was to give the controller a little something to chew on, since the only way
I have to tell how much power a panel or controller CAN produce is to give it a hungry load and see how much
power it will accept, given its maximum power point tracking.

I connected my 1,000W inverter and plugged in a small ceramic heater. It draws around 470W on low, which
should drain my 100AH battery down reasonably fast.

This battery has about a 1,300Wh capacity, and I drained it about half-way, down 660Wh.
