Check DC cable connections and fuses.
Red LED On or blinking
The inverter did shut down because of a protection. It will
no longer automatically restart. The red LED indicates the
reason for shutdown. Remove the cause and then restart
the inverter by switching it Off, and then back On.

3.4 Protections and automatic restarts
Overload
Some loads like motors or pumps draw large inrush currents in a start-up situation. In such
circumstances, it is possible that the start-up current exceeds the over current trip level of the
inverter. In this case the output voltage will quickly decrease to limit the output current of the
inverter. If the over current trip level is continuously exceeded, the inverter will shut down: wait
30 seconds and then restart.
After three restarts followed by another overload within 30 seconds of restarting, the inverter
will shutdown and remain off. The LEDs will signal shutdown due to overload. To restart the
inverter, switch it Off, then On.
Low battery voltage (adjustable)
The inverter will shut down when the DC input voltage drops below the low battery shutdown
level. After a minimum delay of 30 seconds, the inverter will restart if the voltages rise above
the low battery restart level.
