Operating the PV Solar Input
The battery box is comes with a solar input port and a DC to DC controller that provides
an alternative method to charge the internal battery. A solar charge indicator located at
the back of the battery box to indicate the charging status of the internal battery.
The DC to DC controller is a fully automatic self-sustaining device that will initiate the
charge cycle when solar power is available. Please note that the DC to DC controller is
designed to be used with the provided Nature Power 40W solar panel. Connected to
other solar panel may damage the unit or over
charge the battery. If insufficient charge
capacity is not available from the solar source, it is recommended to use the internal 5A
charger to complete the battery charging process through the utility.
