The EVO
TM
is able to operate in 3 modes – Normal (Off-line), On-line and Charger Only
Modes. Normal (Off-line) Mode is the Default Mode. Mode can be changed to Online Mode
or Charger Only Mode through optional Remote Control Model EVO-RC-PLUS (Please see
Section 4.4.2.13 in the Owner’s Manual for EVO-RC-PLUS).
Normal (Offline) Mode: This is the Default Mode . In this mode, the AC input (from the Grid
/ Generator) is the PRIMARY source of AC power and the batteries / Inverter Section of EVO
TM
is
the BACK-UP source of DC-AC power. If qualified AC input (within the programmed voltage and
frequency limits) is available, the Transfer Relay will be switched ON (energized), the EVO
TM
will
operate in “Charging Mode” and qualified AC input from the Grid / Generator 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 "BULK CURRENT" – Value of Current fed from the external solar charge
controller). When the Grid / Generator AC input fails or, is not within the programmed values of
voltage and frequency, the Transfer Relay will be switched OFF (de-energized), the unit will change
over to “Inverting Mode” and the AC Output will be fed from the internal Inverter Section. When
Grid / Generator input is restored, the unit will revert back to “Charging Mode” to charge the
batteries and at the same time, pass through the AC input to the AC output.
Online Mode: In this mode, the Inverter Section of the EVO
TM
is the PRIMARY DC-AC source
of power. The Grid / Generator input is the BACK-UP source of AC power. Online Mode has
2 options of operation (ONLINE OPTION) that can be programmed through optional
Remote Control Model EVO-RC-PLUS (Please see Section 4.4.2.14 in the Owner’s
Manual for EVO-RC-PLUS) . In this mode, even if qualified Grid / Generator AC input is
available (within the programmed voltage and frequency limits), the EVO
TM
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 specified programmed value of low battery voltage (This specified
value of low battery voltage is selected through programmable parameter “LOW VOLT ALARM”
- See Section 4.4.2.8 in the EVO-RC-PLUS Manual). When the battery discharges to the
programmed voltage threshold of “LOW VOLT ALARM”, or lower and remains at this threshold,
or below for a sustained programmed time period, the Transfer Relay will be switched ON
(energized) and the EVO
TM
will change over to “Charging Mode” [The sustained programmed
time period is selected using parameter called “GS DETECT TIME” (0-600 sec; Default 10 sec)
- See Section 4.4.2.16 in the EVO-RC-PLUS Manual. On changing over to “Charging Mode”,
qualified AC input from the Grid / Generator 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 Adaptive Charging algorithm (ONLINE
OPTION: 0=Option 1 - See Section 4.4.2.14 in the EVO-RC-PLUS Manual) or, for a programmed
specified time period (ONLINE OPTION: 1=Option 2 - See Section 4.4.2.14 in the EVO-RC-PLUS
Manual), the Transfer Relay will be switched OFF (de-energized), charging will stop and the unit
will change over to “Inverting Mode”.
