BAtt LoW VoLtAGe:
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:
• W hen the battery voltage drops to the set threshold of "BATT LOW VOLTAGE", the Red
LED marked "Fault" 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.
• I f 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 fault
message "Battery low voltage!" will be displayed. The Green LED marked "Status" will be
switched OFF and the Red LED marked "Fault" will remain ON steady. The buzzer in EVO
Inverter Charger will beep steady.
• I f 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
(LDC Display / LED / Buzzer will be OFF).
• I f 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.
• W hile 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 "Battery low voltage!" fault and shut down of the inverter due to momentary dips
in battery voltage as a result of high power, short duration AC loading (e.g. motor starting,
inrush current etc.), a timer is used to qualify "BATT LOW VOLTAGE"condition only if the
battery voltage drops to or below the set "BATT LOW VOLTAGE" threshold for the set "LV
DETECT TIME". The timer starts as soon as the battery voltage drops to the set threshold of
"BATT LOW VOLTAGE" described above.

LV cUt oFF tiMe:
Even when the Inverter Section is shut down due to "Battery low voltage!" fault condition
as described above, there will still be some power drawn from the battery to keep the other
circuitry in the EVO Inverter Charger alive so that the inverter can be switched on when
the fault gets cleared automatically after the battery has been recharged to the "RESET
VOLTAGE" or when AC input voltage is available. However, if the fault is not cleared over
