Samlexpower EVO-2212E Owner's Manual - (4 Stage Charging)

The equalization current “I

2

” is normally 5% to 10% of the Ah capacity of the battery. 

This current is indirectly computed from the programmed bulk Charge Current. As 

recommended under the Setting mode for the bulk charge current, the bulk 

charge current “Io” is expected to be set at 10% to 20% of the Ah capacity of the 

battery. hence, the Equalization current “I

2

” will be automatically computed at 50% of 

the set bulk Charge Current “Io” which will effectively amount to 5% to 10% of the Ah 

capacity of the battery. for example, the Equalization Current “I

2

” for a 200 Ah capacity 

battery will be 10 A - 20A. The bulk Charge current “Io” for a 200 Ah capacity at 10% - 

20% will be set at 20 A - 40A. The firmware will compute the Equalization Current “I

2

” at 

50% of 20 A (i.e. 10A) or at 50% of 40A (i.e. 20A).

At the end of Equalization Stage, the charger transitions to the programmed float Voltage 

(see programmable range and defaults at Table 5.1). this stage is displayed as"float" 

in the charging mode screens in remote control evo-rc (Please refer to Section 

3.6.1 at Appendix A).

Automatic resetting of charging cycle 

The charging cycle will be reset to the bulk Stage of 3 Stage Charging Profile as follows: 

-  If the AC is reconnected or the battery voltage drops below 12 VDC / 24 VDC (Default). 

Programmable range for this voltage is 10 to 13V for 12V battery and 20 to 26V for 24V battery. 

(This parameter is called "fLOATING EXIT". Please see Table 6.2 and Section 4.4 of Appendix A)

-  If the charger remains in the float Mode for 10 days.

5.9 Switching on AnD Switching off of eQuAliZAtion moDe 

(4 StAge chArging)

The unit comes preset for charging in Normal Charging Profile (3 Stage Charging Profile). 

Equalization Profile (4 Stage Charging Profile) is required to be selected manually as follows:

using on/off Push button on the front Panel: When the unit is in Charging Mode (qualified 

Grid / Generator Input is available), the Green LED “Status” will be flashing once per second. 

Press the ON/Off button for 1 second. The ongoing Normal Charging Mode will be terminated 

and Equalization Mode will be initiated. The Green “Status” LED will start flashing 2 times per sec 

to show that Equalization Mode is active. The unit will complete Equalization Cycle and terminate 

in float Stage. At the same time, the Charge Mode Setting will again reset to Normal Mode 

and the Green LED “Status” will return to 1 flash per second. To terminate Equalization Mode 

prematurely before its completion, press the ON/Off Push button for 1 second.

If the unit was in Inverting Mode (Green LED “Status” steady) and the Mode is set to 

Equalization as above by pressing the ON/Off Push button for 1 second, the unit will 

undergo Equalization Mode whenever  qualified AC input is available from Grid / Generator 

and the unit enters Charging Mode. To terminate Equalization Mode prematurely before its 

completion, press the ON/Off Push button for 1 second. 

note: Procedure described above is to be used when the optional remote 

Control EVO-rC has NOT been plugged into the rJ-45 remote Control 

Jack. Please note if the remote Control has been plugged into the rJ-

45 Jack, the above procedure cannot be activated and the ON/Off of  

Equalization Mode will be controlled by the remote Control EVO-rC.   

using optional remote control evo-rc: Please refer to the attached manual for 

EVO-rC at Appendix A.
