A big spike on my battery graph

Post by pioneerMan »

So I'm trying to make sense of this voltage spike on my battery graph. Somewhere around 7AM, the voltage began to rise, which of course makes sense due to the sun rising. But suddenly the voltage dropped down. There has not been a cloud in the sky at all today, and I was not running any big appliances or electrical loads this morning.

Thoughts?

This view is the voltage measured at the inverter. It would likely be more instructive to know what the chargers were doing during that time.
