The RPi is powered from a USB adapter connected to the load terminals.
A DROK USB tester shows the RPi drawing ~.330 mA, which is greater than the .12mA above. That is how I concluded that the 15L is not measuring battery draw overnight.
I would not expect any great accuracy at those low levels. They claim current accuracy of "2%", but that certainly means 2% of full scale (so, ~0.3 A or more), not 2% of the reading.
And, If it's in "night" mode, I wouldn't expect _any_ solar current. There will be "charge" current, which is just battery current, although I'm not sure of the sign (+ for charge, - for drain, or the opposite). One sure way to tell - disconnect the solar, put a more significant load on it, and see what it reports for battery and load current.
