Troubleshooting
The Cobblestone Effect can sometimes be seen after a forced charge event. Power continues to be drawn to satisfy base load although the batteries do not charge.
It seems to be caused by keeping forced charge times in their fields (e.g. 00:00 to 23:59) when charging is disabled. I have found that removing these charge times will prevent the effect from leaching power during times when the inverter is not meant to be charging.
