Whizbang Jr, EA, and obsessive compulsive.

I thought folks might be interested in how Midnites new battery current sensor is working out.

After a few firmware updates, Bob now has ending amps working really well, and state of charge also fully intergrated into the local app and controller display.

For years weve wanted this, asked for it and now we have it. Here is a 1sec plot of controller output (blue), WBjr (pink) and the difference in yellow which is the house load. The top curve is the raw data, and the lower curve has been put through a moving averge filter.

EA here was set to 2.5A (on the WbJr), and it was pretty close as you can see by the slight dip in the pink curve. The downward spikes in the blue curve are when the controller loads the bank breifly during sweeps.
