~~~~~~~for the sake of curiosity~~~~~~~~~~~~~~~~``
How long to charge its battery?
-------------------------------------------------------------------------------- How much power can the battery hold?
Battery 1100mAh @ 3.7V 1100x3.7 = 4040 mili Watt hours capacity
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~` How much power can the panel put into the system in one day in Atlanta?
Solar Panel ( not the inverter it would be less unless it is
100% efficient)5.5V@130 mA --- capable of 130x5.5 mili Watt hours @100 % insolation
130x5.5=715 miliwatt hours maximum power outputInsolation 10 year average for Atlanta 4.3 hours
Daily average charge capacity for this system at 100% efficiency
715 mWh x 4.3 = 3074 mWh ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~4040/3074=1.3 days to charge its dead battery with this charger operating at 100% here in Atlanta on the average.
