Instruction

PV Limit Current

PV Short Current

PV Reverse Polarity

Night Reverse Charging  

When the charging current of the PV array exceeds its rated current, it will be charged at 
the rated current. NOTE: When the PV modules are in series, ensure that the open circuit 
voltage of the PV array does not exceed the "maximum PV open circuit voltage". 
Otherwise the inverter/charger may be damaged. 

When PV is not charging and short circuit, the inverter/charger is not damaged. 

Fully protection against PV reverse polarity, correct the wire connection to resume normal 
operation. NOTE: The inverter/charger will be damaged when the PV array straight polarity 
and the actual operation power of the PV array is 1.5 times greater than the rated charge 
power! 

Prevent the battery discharging through the PV module in the night. 

Utility Input Overvoltage 

When the utility voltage exceeds 280VDC, it will stop utility charging/discharging. 

Utility Input Under Voltage 

When the utility voltage less than 160VDC, it will stop utility charging/discharging. 

Battery Overvoltage 

When the battery voltage reaches to the set point of Over Voltage Disconnect Voltage,
the inverter/charger will stop charging the battery to protect the battery from being over 
charged to break down. 

Battery Over Discharge 

When the battery voltage reaches to the set point of Low Voltage Disconnect Voltage, the 
controller will stop discharging the battery to protect the battery from being over
discharged to break down. 

Load Output Short Circuit 

Load Output Overload 

Device Overheating 

It will immediately close the output in occurrence of short-circuit and hereafter the output
is automatically recovered in time delay (the first time delay for 5s, the second time delay 
for 10s, the third time delay for 15s); if the short-circuit remains after 3 times of delay, 
restart the inverter/charger only after clearing the fault.

The inverter/charger will stop charging/discharging when the internal temperature is too 
high, and will restore charging/discharging when the temperature is recovered to normal.
