Hi,
I have the suncontrol board connected to 18W/1A solar panel with DC/DC, which brings down the voltage to 6V/3A. The sunboard is connected to 8000mAh battery and RPi3. I had it charging the battery and power the RPi3 during the day and during the night it was only using the battery, until it eventually died. In the morning it started charging the battery when the sun was up and it took it 2-3 hours to charge it enough to turn it on. However, since then, the suncontrol board doesn't seem to provide enough current at the USB port to power both the RPi3 and the 4G/LTE module that I have connected to it. I tried connecting the board to the 5V input with the same result. The RPi3 by itself seems to be using 200mA or so and with th 4G/LTE module goes up to 500mA, but it is not near the max 1A. The suncontrol seems to be able to power on the RPi3 by itself. I tried different batteries with the same result.
Regards,
Peter
