OVERLOAD Overload
The unit goes to bypass and stays that
way as long as there is an overload. The
load transfers from bypass to inverter
when the load is corrected.
INVERTER FAULT
Malfunctioning inverter
Make up to 7 attempts to reconnect to the
inverter.
OVER
TEMPERATURE
Over temperature
Over 90° paralyzes the inverter’s action
and transfers the load to bypass. It returns
automatically to normal operation only
after the temperature goes below 55°.
BATT. NOT
CONNECT
Battery is not connected
Check the status of the battery switch and
the connections to the batteries.
BATTERY UNDER
LOAD
Power failure. Inverter
operating on batteries.
A slow beep indicates that the battery is
