4.5.2.12 INPUT RECOVERY
(Table 4.6: (i) Parameter Screen No. 9 under Column 1 for EVO-1212F / 1212F-HW / 1224F / 1224F-HW / 4248SP
(ii) Parameter Setup Screen No. 11 under Column 2 for EVO-2212/ 2212E / 3012 / 3012E /
2224 / 2224E / 4024 / 4024E)
This parameter determines how EVO
"Battery ultra low voltage!" fault conditions (Srl. Nos. 1 and 2 respectively of TABLE 7.1). The following 2 options are
available under this parameter:
• Option "0=Buffered" (This is the default option)
• Option "1=Direct"
is in "Battery low voltage!" condition (Section 7, Srl 1 of TABLE 7) or in "Battery ultra low voltage!"
When the EVO
TM
condition (Section 7, Srl. 2 of TABLE 7.1) and if AC input is made available before expiry of time set by parameter "LV
CUT OFF TIME" (Section 4.4.2.11), the "Battery low voltage!" / "Battery ultra low voltage!" fault conditions will be
cleared and EVO
Inverter/Charger will recover based on the following 2 options:
TM
a) Option 0=Buffered (Default): Under this option, the unit will initially start in "Inverting Mode",
synchronize with the AC input and then transfer to "Charging Mode". However, if a user programs the
value of "BATTERY LOW VOLTAGE" very close to the "Battery ultra low voltage!" fault threshold of (i) 9V
for 1 ms for EVO-1212F/1212F-HW/2212/3012 or, (ii)18V for 1 ms for EVO-1224F/1224F-HW/2224/4024
or, (iii) 36V for 1ms for EVO-4248SP (Table 7.1), a larger load / larger starting surge on the inverter may
drag the battery voltage to 9V / 18V / 36V or below for 1 ms and trigger "Battery ultra low voltage!" fault.
Under this condition, the user may change to Option 1=Direct
b) Option 1=Direct: Under this option, the unit will directly start in "Charging Mode"
