* Faults will self-recover when the condition returns to normal range
** The inverter/charger must be sent back to the factory for evaluation.
• 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. The fault may be
due to a short-circuited output or a low or weak DC voltage source.
• Inverter Overload Shutdown: If the overload condition exceeds 108% of the rated load for greater than 3.5
seconds, the inverter will shut down. If the overload condition exceeds 200% of rated load for greater than
1.5 seconds, the inverter will shut down immediately. The inverter power will need to be cycled to restart the
inverter.
NOTE: The inverter will only permit an overload event to exceed 200% 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. The inverter will automatically restart once the internal temperature of the
inverter has cooled down.
