Operating Indicators
Indicators at the Output End of the unit show the unit’s
power status and alarms for conditions that could cause
it to shut down.
Power on – The Voltage Input
and Power Output indicators
automatically toggle between input
and output values at three-second
intervals. The three LEDs indicate
the mode the meter is in and the
three digits indicate the voltage
or power value.
Current Overload Protection –
If the inverter is overloaded,
it will shut down to protect itself.
The meter will flash as shown to
indicate Overload Protect.
To restore normal operation,
disconnect the excessive load
and turn the unit Off and On
again using the Power Button.
Short Circuit Protection – If the
AC output of the inverter is short-
circuited for one second or more,
it will shut down to protect itself.
The meter will flash as shown to
indicate Short Circuit Protect and
an alarm will sound.
To restore normal operation,
disconnect the short circuit and
turn the unit Off and On again
using the Power Button.
Low Voltage Protection – If the
DC input voltage drops below
the alarm threshold of 10.5V the
meter will flash as shown to
indicate Low Voltage Protection,
but the unit will continue to
operate. If the input voltage drops
to 10.0V or less, the inverter will
shut down to protect itself, the
meter will continue to flash as
shown, and an alarm will sound.
To restore normal operation, return
the DC input voltage to at least
12V. The inverter will automatically
return to normal operation.
High Voltage Protection – If the
DC input voltage rises above 15.0V,
the inverter will shut down to protect
itself, the meter will flash as shown
to indicate Over Voltage Protection,
and an alarm will sound.
To restore normal operation, return
the DC input voltage to less than
15V. The inverter will automatically
return to normal operation.
