Details of the two options are given below:
0= Option 1 (Default):
• 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
TM
will change over to “Charging Mode” and
qualified 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
TM
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 take place as per the charging profile set through the programmable
parameter "CHARGING PROFILE" (Section 4.4.2.21).
• Transfer Relay will be switched OFF (de-energized) on entering “Float Stage” on
completion of “Absorption Stage” and the unit will change over to “Inverting Mode”
(NOTE: The battery will be charged to 100% State of Charge after the Transfer Relay
has de-energized on entering Float Stage)
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
TM
will change over to “Charging Mode” and
qualified 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
TM
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 profile set through the programmable
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 “Charg-
ing Mode” and revert to “Inverting” Mode.
NOTE:
There is a possibility that the following situations may occur:
(i) The battery voltage may rise higher than the programmed value of "RESET
VOLTAGE" up to the programed value of "ABSORP VOLTAGE" (If the pro-
grammed value of "ABSORP VOLTAGE" is > the "RESET VOLTAGE") due to
continuation of charging for the programmed value of "GEN OFF DELAY" after
the voltage has reached the programmed value of "RESET VOLTAGE"
(ii) The battery may not be charged fully after the Transfer Relay has de-energized
because the programmed values of "RESET VOLTAGE" and "GEN OFF DELAY"
may not match the desired Absorption Voltage / Absorption Time of the battery
being used.
