Thanks Teken, very interesting. Yes this is all new to me!

Here is both a 24 hour graph and table data right around sunset, which was 19:55. And the numbers beginning at 19:55 are consistent through the night, until the shift at 06:15. Sunrise is 05:55.

The panels are Sunpower X21-335-BLK. (qty 21)

A constant 6-7 watts isn’t bad I’ve seen a lot more on different systems that range from 20-45 watts.

The standby usage can be a bit exaggerated, the issue is the power factor is usually very poor when inactive. What does the specs say?

You can try adding a jumper between the bottom 2 ports of a channel in case there's some noise being introduced.

Jumper seems to have done the trick, as long as I get proper readings once daytime hits. . Went from 6-8 watts to 0.0 - 0.3 watts.
Thanks!
