Faults and Warnings - Inverter

Low Battery – The inverter LED will switch to solid Amber when the DC voltage
measured at the inverter input terminals drops below the low battery setpoint. After five
seconds, the inverter will shut down if the DC voltage has not recovered above the low
battery setpoint. When shut down, the inverter LED will blink Red. The inverter will
automatically restart if the battery voltage rises above a preset threshold within 15
minutes. If the battery voltage does not recover within 15 minutes, the inverter will
completely shut-down and the inverter will need to be turned off then on with a local or
remote switch.
Overload – The inverter LED will switch to a solid red when an overload condition is
detected. If the overload condition clears within 5 seconds the LED will return to the
normal state. If the overload condition continues after 5 seconds, the inverter will shut
down and the LED will blink red twice. The inverter power will need to be cycled to
restart the inverter. If the overload condition exceeds 108% of the rated load for greater
than 1.5 seconds, the inverter will shut down and the LED will blink red twice. The
inverter power will need to be cycled to restart the inverter. If the overload condition
exceeds 200% of rated load, the inverter will shut down immediately.
Note: The inverter will only permit an overload event to exceed 108% of rated load
once every 30 seconds. For example, the inverter may go into overload when
starting up a compressor. 30 seconds must pass before attempting to start the
compressor again.
High Temp – If the internal inverter heatsink temperature exceeds the preset limit, the
inverter will shut down in high temp, and the LED will blink red three times. If the
transformer temperature exceeds its limit, the inverter will shut-down, and the LED will
blink red seven times. The inverter will automatically restart once the inverter has
cooled down.
Feedback Fault/Output Short Circuit – If the inverter detects that the output is short
circuited, the inverter will immediately shut off and the LED will blink red four times. If
the input voltage to the inverter is approaching the low battery setpoint and a heavy load
is applied, the output voltage may collapse causing the inverter to fault like an output
short circuit. The inverter power will need to be cycled to restart the inverter.
High Battery – If the DC voltage measured at the inverter input exceeds the maximum
rating of the inverter for up to five minutes, the inverter LED will blind red 5 times. If
the battery voltage drops below the high voltage threshold, the LED will return to its
normal state. If the DC voltage remains above the high voltage threshold for greater
than 5 minutes, the inverter will shut down and the LED will flash red 6 times. The
inverter will resume normal operation when the voltage drops below the high battery
threshold.
Off by CAN – If the inverter has been turned off with a CAN command, the inverter
LED will blink red eight times.
