Audible Alarm
The inverter also gives audible alarms when the following situations occur
Battery Voltage Low
Inverter green LED Lighting, and the buzzer beep 0.5s every 5s.
Battery Voltage High
Inverter green LED Lighting, and the buzzer beep 0.5s every 1s,
and Fault after 60s.
Invert Mode Over-Load
(1)110%<load<125%(±10%), No audible alarm in 14 minutes,
Beeps 0.5s every 1s in 15th minute and Fault after 15 minutes;
(2)125% <load<150%(±10%), Beeps 0.5s every 1s and Fault after 60s;
(3)Load>150%(±10%), Beeps 0.5s every 1s and Fault after 20s;
Over Temperature
Heat sink temp. ≥105ºC(221°F), Over temp red LED Lighting, beeps 0.5s every 1s;

FAN Operation
For 1-3KW models, there is one multiple controlled DC fan.
The DC fan will work in the same way as the one on 1-3KW, while the AC fan will work once
there is AC output from the inverter.
The DC fans are designed to operate according to the following logic:
