Float voltage
Voltage to maintain battery charging (insert the value of single battery string).
Float voltage = Number of battery cells x battery float voltage per cell.
Typical battery float voltage per cell (ask the battery manufacturer for confirmation):
Lead - Acid (VRLA):
Recharge current
Maximum battery recharge current. 16 A
Autonomy time
The autonomy time of the battery.
UPS autonomy on battery mode at full load condition.
This value is calculated based on the battery type, capacity and number of cells.
