3.0 Setup
Info:
The voltage settings shown in Table 3-1 are based on the
Battery Temperature Sensor (BTS) having been at a temperature
of 77° F (25° C), or not connected. If the BTS is connected, the
actual charge voltage will increase if the temperature around
the BTS is below 77° F (25° C), and decrease if higher than 77°
F (25° C). This ensures the batteries receive the correct charge
voltage regardless of temperature.

Note 1: Voltage same as absorption voltage – to prevent equalization.
Note 2: Specifi cations for Concord (Lifeline Series) AGM batteries.
Note 3: Specifi cations for East Penn, Deka, Discover and Trojan AGM batteries.
Note 4: When using the Custom setting, the EQ (Equalization) voltage
adjustment cannot be set lower than the Absorb Voltage setting. Also, the
EQ Voltage adjustment cannot be set higher than 2-volts (12-volt systems),
4-volts (24-volt systems), or 8-volts (48-volt systems) above the Absorb
voltage setting.
03C Max Charge Rate:
Sets the maximum charge rate allowed to
charge the batteries during Bulk, Absorption, Float, and Equalize
charging. Selections are
Max Charge = 0%
up to
Max Charge = 100%
.
The
Max Charge = 0%
setting is available to help minimize charging
while continuing to allow pass-through power. The rest of the selections
are provided to limit the charge rate to the battery bank, which helps
prevent battery overheating caused by charging at too high a charge rate.
The maximum charge selections are provided as a percentage of the
inverter/charger’s maximum charging capability. Refer to the label on
the side of the inverter or the owner’s manual for the inverter/charger
to determine its maximum charge rate. Once you
fi
nd this maximum
charge rate, determine the percentage needed to limit the charge rate
to your battery bank.
