Solar System is kicking butt!!
I only have half my panels on my little power tub
...from 8:30am till 10:45am, it charged half of my 4Ah chainsaw battery, charged from 63% to 100% of my 20Ah jump and usb battery, and most of an old 16Ah Rav usb powerbrick which always has trouble charging to 100%.
..and it is a mostly cloudy day
..note that I haven't received my 280 Ah battery yet...inside the power tub is a 7Ah LiFePo battery! ...since the 7Ah battery is still above 13 volts (14.3), all that power came from just two 100W 12v panels
