SECTION 5 | Battery Charging in Evolution™ Series
3. Stage 3 - Float Stage (See Section 5.7.3 for details)
• Charge at constant voltage (CV) = the programmed value
of parameter “FLOAT VOLTAGE”. (Default value is 13.5V for
EVO-1212F/1212F-HW and 27.0V for EVO-1224F/1224F-HW. For details
of programming range & procedure, refer to Section 4.4.2.4 of EVO-RC-PLUS
Remote Control Manual)
• Reset to Bulk Stage under the following conditions:
i. If the AC input is disconnected and is reconnected.
ii. If battery voltage falls to the programmed value of
parameter "RESET TO BULK"
(Default value is 12.0V for
EVO-1212F/1212F-HW and 24.0V for EVO-1224F/1224F-HW. For
details of programming range & procedure, refer to Section 4.4.2.15 of
EVO-RC-PLUS Remote Control Manual).
iii. If the charger remains in the Float Stage for 10 days

2 = 3 Stage Type 2 1. Stage 1 – Bulk Stage (See Section 5.7.1.1 for details)
• Charge at constant current (CC) = the programmed value
of parameter “BULK CURRENT” (Default value is 20A. For details
of programming range & procedure, refer to Section 4.4.2.1 of EVO-RC-PLUS
Remote Control Manual)
• Transition to Absorption Stage when voltage rises to the
set value for programming parameter “ABSORP VOLTAGE”
(Default value is 14.4V for EVO-1212F/1212F-HW and 28.8V for EVO-
1224F/1224F-HW. For details of programming range & procedure, refer to
Section 4.4.2.2 of EVO-RC-PLUS Remote Control Manual)
2. Stage 2 - Absorption Stage (See Section 5.7.2 for details)
• Charge at constant voltage (CV) = the programmed value
for parameter “ABSORP VOLTAGE”. (Default value is 14.4V for
EVO-1212F/1212F-HW and 28.8V for EVO-1224F/1224F-HW. For details
of programming range & procedure, refer to Section 4.4.2.2 of EVO-RC-PLUS
Remote Control Manual)
• Remain in Absorption Stage till the current reduces to value
= the programmed value of parameter “ABSORP EXIT
AMPS”
(Default value is 4A. For details of programming range & procedure,
refer to Section 4.4.2.20 of EVO-RC-PLUS Remote Control Manual)
• Transition to Float Stage thereafter.
3. Stage 3 - Float Stage (See Section 5.7.3 for details)
• Charge at constant voltage (CV) = the programmed value
of parameter “FLOAT VOLTAGE”.
(Default value is 13.5V for
EVO-1212F/1212F-HW and 27.0V for EVO-1224F/1224F-HW. For details
of programming range & procedure, refer to Section 4.4.2.4 of EVO-RC-PLUS
Remote Control Manual)
• Reset to Bulk Stage under the following conditions:
i. If the AC input is disconnected and is reconnected.
• If battery voltage falls to the programmed value of
parameter "RESET TO BULK"
(Default value is 12.0V for EVO-
1212F/1212F-HW and 24.0V for EVO-1224F/1224F-HW. For details of
programming range & procedure, refer to Section 4.4.2.15 of EVO-RC-PLUS
Remote Control Manual)
ii. If the charger remains in the Float Stage for 10 days
− Lead Acid: Flooded and sealed –
AGM/Gel Cell
− Lithium (See Section 5.11 for
details)
5.7.1.1 STAGE 1 – Bulk Charge Stage
Refer to Fig 5.1 and Srl No. 1 of TABLE 5.2
During the 1st Bulk Charge Stage, the Duty Cycle of the boosted high frequency PWM voltage pulses (Section 5.1.2)
is adjusted continuously to charge the battery at constant current (CC) = the programmed value of parameter "BULK
CURRENT" designated as"Io"(Default value is 20A. For details of programming range & procedure for parameter "BULK
CURRENT", refer to Section 4.4.2.1 of EVO-RC-PLUS Remote Control Manual)
NOTE: The current will slowly ramp up to the programmed value of "BULK CURRENT"
