12v circuit box USB output
Is the USB output on the 12v circuit box always a "6v" panels-in-parallel output, or does it depend on the 6-12v setting switch?
Is the USB output active while the box is set to 12v?
Hi Matthias,
The 2 panel circuit box combines two panels (normally 6V) in either parallel or series. In parallel and if using 6 Volt panels, the output will be roughly 6V under no load (the output is not regulated). On the 12V switch, the panels are put into series.
The USB output on the battery is unaffected by the 6/12V switch, it is always 5 Volts. We don’t recommend charging the Voltaic battery when the circuit box is set to 12 Volts. Instead, disconnect the Voltaic battery and charge whatever you need charged at 12V. When you want to charge the Voltaic battery, switch it back to 6V.
