SECTION 4 | General Description & Principles of Operation
4.6.5.2 Option “1= On-Line”: This option is also called “On-Line UPS Mode” (UPS stands for Un-interruptible
Power Supply). In this mode, the Inverter Section of the EVO is the PRIMARY DC-AC source of power. The AC
input source is the BACK-UP source of AC power. In this mode, even if qualied AC input is available (within the
programmed voltage and frequency limits), the EVO will still operate in “Inverting Mode” and AC output will be
provided by the Inverter Section as long as the batteries are in charged condition above the specied programmed
value of low battery voltage that is set through programmable parameter “LOW VOLT ALARM” [See Section
4.4.2.8 of EVO-RC-PLUS Remote Control 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 set by programmable parameter “GS DETECT TIME” [See Section 4.4.2.16 of EVO-RC-PLUS Remote
Control Manual], the EVO will change over to “Charging Mode”. On changing over to “Charging Mode”,
qualied AC input 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, 4 in Fig 2.1), the internal AC Charger will limit the charging current as follows:
Value of charging current produced by EVO
Charging Section
=
Programmed value of charging current set by
parameter “BULK CURRENT” [See Section 4.4.2.1
of EVO-RC-PLUS Remote Control Manual] minus
(Value of current fed from the external solar charge
controller)
Under the following 2 conditions, “Charging Mode” will be terminated, and the EVO will switch back to “Inverting
Mode”. Switching from “Charging Mode” back to “Inverting Mode” has 2 options under programming parameter
“ONLINE OPTION” [See Section 4.4.2.14 of EVO-RC-PLUS Remote Control Manual]:
i. When Parameter “ONLINE OPTION” is set at option “0= Option 1” [See Section 4.4.2.14 of EVO-RC-PLUS
Remote Control Manual]:
EVO
TM
will switch back from "Charging Mode" to "Inverting Mode" after completion of 3-Stage/ 2-Stage
charging prole programmed through parameter "CHARGING PROFILE" [See Section 4.4.2.21 in the EVO-
RC-PLUS Remote Control Manual]
ii. When Parameter “ONLINE OPTION” is set at option “1= Option 2” [See Section 4.4.2.4 in the EVO-RC-PLUS
Remote Control Manual]:
EVO
TM
will switch back from "Charging Mode" to "Inverting Mode" when the batteries have charged to
the voltage threshold set by parameter "RESET VOLTAGE"[See Section 4.4.2.7 in the EVO-RC-PLUS Remote
Control Manual] and have remained at this threshold or higher for time period set by parameter "GEN OFF
DELAY" [See Section 4.4.2.18 in the EVO-RC-PLUS Remote Control Manual].
