Instruction Logo	Indicator Light Color	Normal State	Abnormal State	Cause of Abnormity
PV indicator	Green	Light on	Flash or off	Light on when the operation goes well; Light off when PV under voltage and it will flash  when PV over voltage.
LOAD indicator	Green	Light on	Flash	Light on when the load is normal, while it will flash when over current, the battery has low voltage and the load has short circuit.
Fault indicator	Red	OFF	Flash or light on	Light off when the operation goes well;  It will light up when the module has fault, the battery has short circuit, the load has short circuit and there is over temperature protection; It will flash when there is PV over voltage.
