* Faults will self-recover when the condition returns to normal range
** Faults may be due to a short-circuited output or a low or weak DC voltage source.
• Low Battery 0–5 Seconds: The DC voltage measured at the inverter input terminals has dropped below the
low battery setpoint.
• Overload 0–5 Seconds: Overload condition has been detected. If the condition clears within 5 seconds, the
LED will return to normal state.
Inverter Low Battery Shutdown: After five seconds of low battery, the inverter will shut down if the DC
•
voltage has not recovered. 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 restarted with a local or remote switch.
• Inverter Overload Shutdown: 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. 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 Heatsink: The internal inverter heatsink temperature has exceeded the preset limit, and the
inverter will shut down in high temp.
• System Overload/Output Short Circuit: The inverter has detected that the output has short circuited. 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 0–5 Minutes: DC voltage measured at the inverter input has exceeded the maximum rating of
the inverter for up to five minutes, and there will be a high battery fault. If the battery voltage drops below the
high voltage threshold, the LED will return to its normal state.
