After a few days of cold rain, the sun is out!!
That's more like it!!
Since it's so damp in the basement (sump pumps are running),
I set the differential to 5F.. It's now back to 20F..
The basement air temp is up 4 deg F, since this morning..
I've got the logging started..
The hot water tank sensor is now showing 125.9 F up from about 90 this morning..
That PV is working nicely right now.. Running about 1200 watts.
