SECTION 4 | Parameter Setup
• The Transfer Relay will be switched ON (energized) if the battery voltage drops to the voltage threshold of “LOW VOLT
ALARM” (Section 4.4.2.8) or lower for sustained period = “GS DETECT TIME” (Section 4.4.2.16). The EVO™ will
change over to “Charging Mode” and qualied AC input from the Grid will be passed through to the AC Output and
at the same time, the Internal AC Charger will start charging the battery. If an external Solar Charge Controller is also
connected to the External Charging Terminals (3 and 4, Fig 2.1 in the Owner's Manual for Evolution™ Series Inverter/
Charger), the internal AC Charger will limit the charging current to a value = (Programmed Value of Bulk Current –
Value of Current fed from the external Solar Charge Controller).
• Charging will be carried out till the batteries are charged as follows and then, the Transfer Relay will be de-energized to
exit Charging Mode and revert back to Inverting Mode:
o For Parameter “CHARGING PROFILE” (Section 4.4.2.21) set for 3 Stage Charging Prole as per:
(i) “Option “0 = 3 Stage Type 0”, (ii) Option “1 = 3 Stage Type 1” and (iii) Option “2 = 3 Stage Type
2”
• The Transfer Relay will be de-energized to exit Charging Mode and revert to Inverting Mode as soon
as the battery bank is charged to the voltage threshold set by parameter “FLOATING VOLTAGE”
(Section 4.4.2.4)
o For Parameter “CHARGING PROFILE” (Section 4.4.2.21) set for 2 Stage Charging Prole as per
“Option “3 = 2 Stage Type 1”
• The Transfer Relay will be de-energized to exit Charging Mode and revert to Inverting Mode when the
battery bank is charged to voltage threshold set by parameter “ABSORP VOLTAGE” (Section 4.4.2.2)
and remains at this level for time period set by parameter “ABSORP TIME” (Section 4.4.2.19)
o For Parameter “CHARGING PROFILE” (Section 4.4.2.21) set for 2 Stage Charging Prole as per
“Option “4 = 2 Stage Type 2”
• The Transfer Relay will be de-energized to exit Charging Mode and revert to Inverting Mode when the
battery bank is charged to voltage threshold set by parameter “ABSORP VOLTAGE” (Section 4.4.2.2)
and remains at this level for time period of 6 min
o For Parameter “CHARGING PROFILE” (Section 4.4.2.21) set for 2 Stage Charging Prole as per
“Option “3 = 2 Stage Type 3”
• The Transfer Relay will be de-energized to exit Charging Mode and revert to Inverting Mode when the
battery bank is charged to voltage threshold set by parameter “ABSORP VOLTAGE” (Section 4.4.2.2)
and subsequently, the charging current drops to threshold set by parameter “ABSORP EXIT AMPS”
(Section 4.4.2.20)
1= Option 2:
• The Transfer Relay will be switched ON (energized) if the battery voltage drops to “LOW VOLT ALARM” (Section
4.4.2.8), or lower for sustained period = “GS DETECT TIME” (Section 4.4.2.16). The EVO™ will change over to
“Charging Mode” and qualied AC input from the Grid will be passed through to the AC Output and at the same
time, the Internal AC Charger will start charging the battery. If an external Solar Charge Controller is also connected
to the External Charging Terminals (3 and 4, Fig 2.1 in Owner's Manual for Evolution™ Series Inverter/Charger), the
internal AC Charger will limit the charging current to a value = (Programmed Value of Bulk Current – Value of Current
fed from the external Solar Charge Controller).
• Charging will proceed as per the Charging Prole selected through parameter "CHARGING PROFILE" (Section 4.4.2.21)
• The Transfer Relay will be switched OFF (de-energized) after the programmed value of “GEN OFF DELAY” (Section
4.4.2.18) counted from the time the battery voltage rises to the programmed value of “RESET VOLTAGE” (Section
4.4.2.7). The unit will exit “Charging Mode” and revert to “Inverting” Mode.
