To prolong battery cycle life, Rolls recommends setting the Low Voltage
Disconnect (LVD) between 1.85 volts per cell (VPC) to 1.95 volts per cell (VPC).
This may be adjusted up or down, depending how often you wish to run the
charging source (generator or alternative power) when the voltage of the
battery bank reaches the programmed set point.
WARNING: Low Voltage Disconnect only cuts off the draw from the inverter/
charger. It does not disconnect all loads from the battery bank. A prolonged
connection will eventually lead to over-discharge and battery collapse.
OTHER CHARGER MODES
Many Inverter and Charge Controller manufacturers design and include other
operational modes to enhance their products. It is recommended that you
contact the manufacturer to better understand how these operate and properly
program the Rolls recommended charging parameters. See Table 2 (a) & 2 (b)
Flooded Charging Parameters.
