Setup
◊ Set Battery Type (CC/CV) – The CC/CV selection provides a Constant Current/Constant
Voltage (CC/CV) charging method with an adjustable charge voltage and a setting that limits
output current—if needed. It consolidates all the battery charge settings that are required for
a 2-stage charging cycle (i.e., Constant Current and Constant Voltage).
Note: CC/CV settings only display if CC/CV has been selected from the 03 Battery Type menu.
Info: If CC/CV has been selected from the 03C Battery Type menu, the following
menus are no longer accessible and display “CC/CV Controlled” when selected: 01D
Max Charge Amps, 03D Absorb Done, 03F Max Charge Time, 03G Final Charge Stage,
03H EQ Reminder Days. This is to prevent charging confl icts that could occur while in
the CC/CV profi le.
CAUTION: Whenever the CC/CV battery type is selected, some settings—within the
menus that are no longer accessible—are internally linked to the CC/CV settings and
can be automatically changed. Because settings can be automatically changed once
CC/CV has been selected, if a different battery type is selected all charge settings must
be reviewed to ensure they are correct for the new battery type selection.
 Set Max Charge Amps – Sets the maximum charge amperage allowed to charge the
batteries during the CC/CV charge cycles. The range of settings are provided to limit the
charge current to the battery bank, which helps prevent battery overheating caused by
charging at too high a charge rate.
Default: 200 ADC
Range: 20 - 990 ADC
 Set CV Charge Volts – Sets the voltage level at which the charger will hold the bat-
teries during the Constant Voltage cycle.
Default: 13.8 VDC (12v), 27.6 VDC (24v), 55.2 VDC (48v)
Range: OFF, 12.0-16.0 VDC (12v), 24.0-32.0 VDC (24v), 48.0-64.0 VDC (48v)
Info: If the BMK (Battery Monitor Kit) is connected, the DC amps value determined by
the BMK (under METER: 05D DC Amps-BMK) will be used by the CC/CV’s Max Charge
Amps setting instead of the inverter’s DC calculated current (shown under METER: 01B
DC Amps)—as it is more accurate (+/- .1 ADC).
