Value of charging current produced by
EVO™ Charging Section
=
Programmed value of charging current set by pa-
rameter “BULK CURRENT”

the
value of current fed from the external solar charge
controller
When AC input fails or, is not within the programmed values of voltage and frequency, the unit will change over to
“Inverting Mode” and the AC Output will be fed from the internal Inverter Section of EVO™. When the AC input
is restored, the EVO™ will revert back to “Charging Mode” to charge the batteries and at the same time, pass
through the AC input to the AC output.
4.8.5.2 Option “1= On-Line”
: This option is also called “On-Line UPS Mode”
(UPS stands for

. 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 qualified 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 specified 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”,
qualified 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:

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 profile 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”
