TROUBLE / SYMPTOMS
POSSIBLE CAUSE(S)
SUGGESTED REMEDIES
AC OUTPUT IS AVAILABLE
On the inverter
• GreenLEDonthefrontpanelofthe
inverter is oN
• RedLEDisOFF
• Buzzeralarmsoundsintermittentlywhen
DC input voltage drops to Low DC Input
Voltage Alarm Threshold of 11V +/- 0.3V
when delivering high power loads
• YellowLEDcomesONwhenbuzzer
alarm is sounded.
On the Remote Control SSW-R1-12B
(For SSW-1000-1500-12A)
• DCinputvoltageisbeingdisplayedand
intermittently drops to Low DC Input Volt-
age Alarm Threshold of 11V +/- 0.3V when
delivering high power loads
• Message“InputFault”intermittently
flashes whenever DC input voltage drops to
Low DC Input Voltage Alarm Threshold of
11V +/- 0.3V
• PowerBarGraphwillbeONiftheoutput
power is > 50W to 100W
Intermittent buzzer alarm due to
intermittent high AC loads
1. DC input wire size is not adequate for
higher capacity loads or there is loose
connection between the battery and the
inverter leading to DC input voltage falling
below the Low DC Input Voltage Alarm
Threshold of 11V +/- 0.3V
2. The battery has developed sulfation due
to undercharging. In this condition, the
internal resistance of the battery rises above
normal and hence causes abnormal voltage
drop on its terminals at higher discharge
current consumed by higher capacity load
1. Use thicker wires between the battery and
the inverter and tighten all DC input circuit
connections
2. Check internal resistance of the battery and
remove sulfation by equalizing the battery
or replace the battery
NO AC OUTPUT

Shutdown due to low DC input voltage
1. DC input wire size is not adequate for the
capacity of the AC load or there is loose
connection between the battery and the
inverter leading to DC input voltage falling
below the Low DC Input Voltage Shutdown
Threshold of 10.5V +/- 0.3V
