NOTE: Current output ratings were measured with 75% of the PV array’s Voc (Open Circuit Voltage)
*NOTE: Calculated by adding battery nominal voltage to the maximum input operating voltage (48V battery
max)
* **NOTE: Measurement Accuracies: +/- 0.12V, offset calibration adjustment maybe necessary

Default Battery Charge Set Points
The table below describes the default preset voltages for the different nominal battery voltages.
This means that if you set the Classic from the QUICK START to a different battery voltage, the
Classic will take the default voltage set points. If you manually adjust the Absorb, Float, or
Equalization voltage set points, and then nominal battery voltage is changed to a different nominal
voltage, (i.e., from 24V to 12V), manual adjustments may be required.
