Maximising your Solar Harvest using the DC2DC+
The Solar Input on the DC2DC+ unit has a maximum rated INPUT current of 30amps. This
means it is optimised for using higher voltage ‘grid’ type modules for best output performance
The maximum achievable output using standard 20Voc solar modules will be approximately
35amps @ 14.4Vdc output.

* Maximum achievable output on the DC2DC+ unit when using 20Voc Solar Panels will be
the approximately 35amps.
** Maximum achievable output on the DC2DC+ unit when using 43Voc Solar Panels will be
the approximately 47amps.
## IMPORTANT NOTE: Estimated Amps Output is quoted based upon PERFECT Solar
conditions including Sun Angle, Panel Mounting angle and Orientation to the sun. It
needs to be noted that panel performance alters dramatically between Summer and
Winter periods and actual performance may be impossible to predict.
