• Nominal voltage: The nominal voltage of the battery bank. Typically, 12V, 24V or 48V.
• Battery type: Adjusts charging parameters for the particular type of battery including temperature correction.
• Energy storage capacity: The total energy storage capacity of the system. This will be in Amp-hours (Ah) for lead acid batteries.
• Low voltage disconnect: If the charge controller has lighting control, the charge controller can often be set to automatically disconnect lighting loads if the battery bank voltage reaches a certain minimum value in order to protect it from deep discharges that can greatly reduce cycle life. Typically set at around 20% state of charge (SOC). It may be also possible to set the value at which the lighting is allowed to reconnect to give the battery bank sufficient time to recharge - a higher value than 20% SOC is recommended.
• Charging set points: The voltages at which different charging phases start and stop vary depending on the battery type and manufacturer. Manufacturers of batteries will provide specific charging specifications in the product manual for bulk, absorb, float, and equalization charging. These values will often be given as a range, it is recommended to program the charge controller to the upper end of the range for each of these values.
