(within the programmed voltage and frequency limits) is available, the EVO always operates in
"Inverting Mode" and AC output is provided by the Inverter Section as long as the battery is
in charged condition above the programmed value of "LOW VOLT ALARM" [(i) for 12V: 9.5V
– 12.5V / Default 11.0V (ii) for 24V: 19.0V – 25.0V / Default 22.0V]
When the battery discharges to the programmed value of "LOW VOLT ALARM" [(i) for 12V:
9.5V – 12.5V / Default 11.0V (ii) for 24V: 19.0V – 25.0V / Default 22.0V], or lower and remains
at this, or below this threshold for continuous programmed period of "GS DETECT TIME" (0-
600 sec; Default 10 sec), the Transfer Relay is switched ON (energized) and the unit changes
over to "Charging Mode". Qualified AC input from the Grid is passed through to the AC
Output and at the same time, the Internal AC Charger starts charging the battery. If an external
Solar Charge Controller is also connected to the External Charging Terminals (3 and 4, Fig 2.1),
the internal AC Charger will limit the charging current to a value = (Programmed Value of
Charging Current – Value of Current fed from the external solar charge controller).
When the battery has been re-charged either fully through complete, 3-Stage Charging
algorithm (Option 1) or, for a programmed time period (Option 2), the Transfer Relay will be
switched OFF (de-energized), charging will stop and the unit will change over to "Inverting
Mode". The following 2 options can be programmed through Parameter Setup Menu Item
"ONLINE OPTIONS"
0= Option 1 (Default):
• T he Transfer Relay will be switched OFF (energized) if the battery voltage drops to
"LOW VOLT ALARM" [(i) for 12V: 9.5V – 12.5V / Default 11.0V (ii) for 24V: 19.0V –
25.0V / Default 22.0V] or lower for continuous period = "GS DETECT TIME" (0-600
sec; Default 10 sec). The EVO 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), the
internal AC Charger will limit the charging current to a value = (Programmed Value of
Charging Current – Value of Current fed from the external solar charge controller).
• C harging will take place as per full and complete 3-Stage Charging Algorithm
("CHARGE MODE" 0=Normal).
• T ransfer 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:
• T he Transfer Relay will be switched ON (energized) if the battery voltage drops to
"LOW VOLT ALARM" [(i) for 12V: 9.5V – 12.5V / Default 11.0V (ii) for 24V: 19.0V –
25.0V / Default 22.0V], or lower for continuous period = "GS DETECT TIME" (0-600
sec; Default 10 sec). The EVO 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), the
internal AC Charger will limit the charging current to a value = (Programmed Value of
Charging Current – Value of Current fed from the external solar charge controller).
