Some cool battery graphs
I'm checking out the Costco GC2 batteries and Iota 55A converter as well as the new 16-bit a/d for Arduino. Prior to discharging the 208AH GC2 batteries, they were top charged with 16V for about ...

It makes sense to see the oscillation. When the ac sine wave passes through zero, there isn't any ac current and the dc current should get smaller. A filter capacitor within the inverter reduces the effect.
Here's a few more parts that come in handy. The remote on/off switch is very good. And you need some feedback that the program is doing what you want it to. A buzzer gives me audible feedback during various operations.
I get a lot of info from "Arduino Cookbook" by Michael Margolis.

Nice setup and graphs. What is causing the wide line in the current? When expanded, it looks like something is varying about 1/4A.
Salvo said (just above the graph you are commenting about) ."The current oscillates due to inverter operation. It does not pull a constant current"
I have downloaded "Arduino Cookbook" Thanks...... I think i will just use leds instead of a buzzer. ( it will likely be a permanent mount in the rv).
Are you planning on a 50% to full charge graph like the last graph?
