If the off-grid load is overloaded, indicators LED1 and LED2 on the inverter blink orange
slowly. Reduce the off-grid load power and manually clear the alarm or until the inverter is
recovered. The inverter attempts to restart at an interval of 5 minutes. If the inverter fails to
restart for three times, the interval changes to 2 hours. If the inverter is standby in off-grid
mode, check the inverter alarms and rectify the fault.
