4.4.2.6 BATT OVER VOLT (Table 4.3, Screen No. 6)
This parameter sets the upper battery voltage threshold at which inverting / charging operations are switched OFF to
protect the unit against damage due to battery overvoltage:
•
AC input is not available and EVO™ Inverter/Charger is operating in Inverting Mode: When the battery
voltage rises to the set upper threshold of "BATT OVER VOLT", the Inverter Section will be shut down and fault
message "Battery over voltage!" will be displayed on the LCD screen. The Blue LED marked "Status" will switch
OFF and the Red LED marked "Fault" will remain ON steady. The buzzer on EVO™ Inverter/Charger will beep
steady. The fault will be cleared automatically when the battery voltage drops to 0.5V below the set upper
threshold of "BATT OVER VOLT"
•
AC input is available and EVO™ Inverter/Charger is operating in Charging Mode: When the battery
voltage rises to the set upper threshold of "BATT OVER VOLT", the Transfer Relay will be de-energized, charging
and pass through will be stopped and PWM drive to the Inverter Section will be switched OFF. Fault message
"Battery over voltage!" will be displayed on the LCD screen. The Blue LED marked "Status" will switch OFF and
the Red LED marked "Fault" will remain ON steady. The Buzzer on EVO™ Inverter/Charger will beep steady.
The fault will be cleared automatically when the battery voltage drops to 0.5V below to the set upper threshold
of "BATT OVER VOLT". The unit will start in Inverting Mode, synchronize with the AC input and then, the
Transfer Relay will be energized to transfer to AC input at zero crossing. The unit will, thus, resume operation in
"Charging Mode".
