Parameter Setup
LOW VOLT ALARM:
When inverting, if battery voltage is under the set value, the Red LED marked "Alarm" flashes
once per second. The buzzer in EVO Inverter Charger will beep once per second. If Relay
Function is set for Generator, the relay will turn ON. If in On-Line Mode, it will transfer from
Inverting Mode to Charging Mode.

BATT LOW VOTLAGE:
This parameter sets the battery low voltage threshold at which the Inverter Section / the com-
plete EVO Inverter Charger will be shut down to protect the battery from deep discharge:
• When the battery voltage drops to the set threshold of “BATTERY LOW VOLTAGE”, the
Red LED marked “Alarm” will flash once per second. The buzzer in EVO Inverter Charger
will beep once per second. The Inverter Section will continue to operate normally and the
Green LED marked “Status” will continue to be ON steady.
• If the battery voltage stays at or below the above threshold for duration equal to the “LV
DETECT TIME” described below, only the Inverter Section will be switched OFF and mes-
sage “Battery low voltage!” will be displayed. The Green LED marked “Status” will be
switched OFF and the Red LED marked “Alarm” will remain ON steady. The buzzer in EVO
Inverter Charger will beep steady.
• If the “Battery low voltage!” fault condition is not reset within the “LV CUTOFF TIME”, the
EVO Inverter Charger will be shut down completely after “LV CUTOFF TIME” has elapsed.
• If the batteries are charged by external charger connected directly to the batteries or
through the External Charger Input (3, 4 in Fig 2.1 in EVO Inverter Charger Manual) and
the battery voltage recovers to the set “RESTART VOLTAGE” before the expiry of “LV CUT
OFF TIME” while in “Battery low voltage!” fault condition, the Inverter Section will restart
and the “Battery low voltage!” fault condition will be cleared.
• While in “Battery low voltage!” fault condition, if AC input is made available before the
expiry of “LV CUT OFF TIME”, the “Battery low voltage!” fault condition will be cleared.
The EVO Inverter Charger will restart in Inverter Mode, synchronize with the AC input and
then, transfer to the AC input at zero crossing. It will now operate in Charging Mode.

LV DETECT TIME:
To prevent low battery shut down of the inverter due to momentary dips in battery volt-
age as a result of high power, short duration AC loading (e.g. motor starting, inrush current
etc.), a timer is used to qualify battery low condition only if the battery voltage drops to or
below the set “BATTERY LOW VOLTAGE” threshold for the set “LV DETECT TIME”. The timer
starts as soon as the battery voltage drops to the set threshold of “BATTERY LOW VOLTAGE”
described above.
