Operation
5.3.5 LED Indicator Guide
Use the LEDs and the LCD display to determine the operating status.
Table 5-1, LED Indicator Guide
LED Status Meaning
PWR
(green)
OFF
1) Inverter is disabled; 2) Remote’s in Power Save mode –
press any button to activate LEDs; 3) No power to remote
(check remote cable or the power to the inverter); or, 4) No
AC power at the inverter’s AC output terminals.
ON
AC power is available from the inverter, utility, or generator at
the inverter’s AC output terminals.
FAULT
(red)
OFF Normal operation.
ON
A fault condition has been detected. Check the LCD display to
fi nd and correct the cause.
CHG
(green)
OFF
1) Remote is in Power Save mode – press any button to
activate LEDs; or, 2) Charger off – no utility or AC generator
present.
ON
Bulk, Absorb, Float, or Equalize charge mode (see the LCD
display to determine charge status).
BLINKING, dis-
play says “Char-
ger Standby”
The charger is in Charger Standby mode. This occurs when the
ON/OFF CHARGER button is pressed to disable the charger.
BLINKING,
display says
“Full Charge” or
“Silent”
The charger is in Battery Saver mode. This mode monitors the
battery voltage level and only charges if the battery voltage
decreases to a low level. Silent mode will automatically start
charging when the ReBulk Volts setting is reached.
BLINKING,
display shows a
charging status
(i.e., Bulk, Ab-
sorb, Float)
The charger current is automatically decreased because:
1) Charger Back-off – the inverter’s internal temperature
is getting hot, the current is decreased to reduce/maintain
temperature; or, 2) Low AC Input Voltage – the input AC
voltage is low, the charger is disabled to help stabilize
incoming AC voltage to prevent AC disconnect.
BLINKING,
display does
not show any
charge status
The inverter is detecting AC voltage (from utility or an AC
generator) on the inverter’s AC input terminals.
INV
(green)
OFF
1) Inverter is disabled; or, 2) Remote is in Power Save mode -
press any button to activate the LEDs.
ON
Inverter is enabled – 1) Supplying AC power on the output;
or, 2) In Inverter Standby (if both INV and CHG LEDs are on);
the inverter will automatically supply AC power to the loads if
utility or generator power is lost.
BLINKING
Inverter is in Search mode (the AC load is below the SETUP:
02A Search Watts setting).
