Inverter Faults and Warnings Continued
• System Overload/Output Short Circuit: The inverter has detected that the output has short circuited.
Alternatively, 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. The fault may be due to a short-circuited output or a low or
weak DC voltage source.
• 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.
• High Battery >5 Minutes: DC voltage has not dropped below the high voltage threshold in under 5 minutes,
and the inverter will shut down. The inverter will resume normal operation when the voltage drops below the
high battery threshold.
High Temp Transformer: The transformer temperature has exceeded its limit, and the inverter will shut-
•
down. The inverter will automatically restart once the internal temperature of the inverter has cooled down.
• Inverter Off by CAN: The inverter has been turned off with a CAN command.
Reverse Polarity: The inverter has detected that the battery is connected backwards. The inverter must be sent
•
back to the factory for evaluation.
• AC Feedback Detected: The inverter has detected that a live AC input is miswired to the AC output
terminals/wires, and will not start. Check for proper AC input and output wire installation. The inverter should
start unless the unit is damaged due to miswiring.
