8、Trouble shooting
1）Red LED shows:
A、Check if the input voltage to inverter is lower than 10.5V or higher than 28V.
B、Check it the AC cable connect to utility power correct or the utility power is disconnect.
2）No LED shows:
A、Check if the DC input voltage is in too low.
B、Check if the DC fuse is broken.
9、 LED Indicator
A、Red LED：
1、Low-voltage protection (input DC voltage is less than 10.5VDC).
2、Over-voltage protection (Input DC voltage is greater than 28.5VDC).
3、Over-temperature protection (when the chassis temperature is above 75℃,
the temperature dropped about 2-10 minutes to restart automatically after cooling).
4、Fault Protection (when 110VAC or 220VAC power outage or shutdown).
5、Islanding protection: When the electric supply stop, the inverter automatically shut down output.
B、Green LED：
1、Green LED flashing: The inverter is adjusting power output. MPPT is in working condition.
2、Green LED long in time: The inverter is in working condition with the maximum output power.
