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.

Output Watts

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.

Over Current	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	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	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	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.
