DC Input (CH2 – Solar / PV):
PV Input Voltage Range 14.5 - 45V
PV Input Under Voltage Shutdown < 14.5V
PV Input Under Voltage Recovery 15.0V
PV Input Over Voltage Shutdown > 45V
PV Input Over Voltage Recovery = < 44V
PV Charging Mechanism MPPT type ( approx. 97% eciency)
Maximum Input
800W *See Note below and “Maximising your
Solar Harvest using the DC2DC 24V“
*Note: The recommended maximum solar wattage input for the DC2DC 24V Charger is 800w.
You can however “overdrive” the MPPT controller. Please note that doing this is partially
an economic decision. You can install more power than the controller can use and this will
contribute to better power availability. Enerdrive suggest a total maximum overdrive of
20% (total 1000w). On cloudy (or intermittent sunny) days there will be little or no power
shaving and the extra power will serve the battery well with more energy harvest earlier
and later in the day.
Maximising your Solar Harvest using the DC2DC 24V
The Solar Input on the DC2DC 24V 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
15amps @ 14.4Vdc output.
Panel Array Rated Wattage & Volts Open Circuit rating
Estimated DC Amps
* Maximum achievable output on the DC2DC 24V unit when using 20Voc Solar Panels will
be the approximately 15amps.
** Maximum achievable output on the DC2DC 24V unit when using 43Voc Solar Panels will
be the approximately 30amps.
## 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.
