3.0 Setup
Info: If the BMK (Battery Monitor Kit) is connected, the DC amps
value determined by the BMK (under METER: 03 BM: Meters/ DC
Amps) will be used by the CC/CV’s Max Amps setting instead of the
inverter’s DC calculated current (shown under METER: 01A INV/
CHG Meter/ DC:)—as it is more accurate (+/- .1 ADC).
 EndChg – These selections determine when the second stage of
charging (Constant Voltage) is fi nished. If using the DoneTime or Do-
neAmps selections, once the constant voltage charge cycle is fi nished,
it transitions to a Silent charge stage. After entering the Silent Charge
mode, the charger automatically stops charging, but is still actively
monitoring the battery voltage. The charger will remain “Silent” until
the battery voltage drops to the Recharge setting, at which time the
charger will start another Constant Current/Constant Voltage charge
cycle (see Figure 3-10) .
Default: Time
Range: Time, DC Amps, Hold VDC
* DoneTime – The DoneTime selection is used when a specifi c
time is selected to be the best solution for determining when the bat-
teries are fully charged and the Constant Voltage stage needs to end.
This setting determines how long the charger will hold the battery
voltage at the Chg Volts setting—based on a set time period. When
using time, the battery bank size will typically determine the length
of the DoneTime setting. The larger the battery bank, the longer the
time needed to ensure a full charge to the batteries. If the setting
is from 0.1 to 25.5 hrs, the charger transitions to the Silent Charge
mode after the battery voltage has been at the charge voltage setting
for the selected time. Refer to Table 3-2 to assist you in selecting the
DoneTime setting based on the AHr capacity of your battery bank.
Default: 1.5 Hrs
Range: 0.1-25.5 Hrs
Note: After choosing DoneTime, the MaxTime and Recharge settings
must be determined (pp. 23-24).
