Note¹:
Voltage same as absorption voltage—to prevent equalization charge.

Note³:
Charge voltages for East Penn, Deka, Discover and Trojan AGM batteries.
Note
4
:
When using 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.
Note
5
:
For inverter models <Level 5, the Float Voltage level is
13.1 VDC
(12-volt models); 26.2 VDC (24-volt models); or 52.4 VDC (48-volt models).
See Section 3.2 for inverter level information.
CAUTION:
If using Lithium batteries and selecting the LFP battery
type pro
fi
le—to prevent the charger’s output voltage level from
changing based on temperature—REMOVE the BTS from the inverter.
Info:
The charge voltage levels shown in Table 3-4 are with the
Battery Temperature Sensor (BTS) at a temperature of 77° F (25° C),
or not connected. If the BTS is connected, the actual charge voltage
level 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.
