• 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
TM
(LDC Display / LED / Buzzer will be OFF).
• I f the batteries are charged by external Solar Charge Controller connected directly to the
batteries or through the External Charger Input (3, 4 in Fig 2.1 in the Owner's Manual for
Evolution Series Inverter/Chargers) and the battery voltage recovers to the set "RESET
TM
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
TM
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
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
a long period of time, the battery may get completely discharged. Hence, a timer is used
to record the duration of "Battery low voltage!" condition. The EVO
be completely shut down (LCD Display / LED / Buzzer will be OFF) when the duration of the
"Battery low voltage!" fault condition as described above is equal to the "LV CUT OFF TIME".
