Frequently asked questions and treatment processes
On-scene judgment and problem solving
1. Overload indicator flickers when controller is under load: output from this load exceeds the rated load by 10%. Please check whether there is overloading.
2. Controller shuts off the output when under load and overload indicator turns on: output from this load exceeds the rated load by 20% or there may be short circuit. Please check load condition.
3. No charging or display: open the top cap of controller and check whether DC fuse shim of controller has burnt out. If the fuse protector is detected to have burnt out, check whether polarity of chargeable battery and photocell unit is reversed. After correction, please replace with new DC fuse shim of the same specifications.
4. Out-of-function of wind turbine: When there is sufficient wind, one wind turbine stops working or turns slowly while others work normally. Please check whether rear control of wind turbine is in the same direction with wind; check whether controller indicates over-voltage. If everything turns out normal, please disconnect controller and battery; then connect to the battery after controller stops working. If wind turbine still doesn’t work or turns slowly, disconnect wind turbine and controller. If wind turbine is working normally, there is something wrong with controller intelligent shut-down system in need of replacement.
5. Over-voltage of charging: when voltage of chargeable battery exceeds the upper limit of protection voltage of over-charging by more than 5% and there is still charging current on photocell unit or wind turbine indicated by inserted ammeter, there may be damage to charging controller in need of replacement.

Indicators and keys Description
控制器充电指示
Charging
The indicator flickers when the battery is being charged by wind or solar energy; the indicator is off when there is no charging.
控制器欠压指示
Under-voltage
The indicator will turn on when the controller detects that chargeable battery voltage is below the set lower limit; the indicator turns off when voltage returns within normal limits.
控制器过压指示
Over-voltage
Indicator will turn on when controller detects that chargeable battery voltage exceeds the upper limit; indicator turns off when voltage is reduced to within normal limit. Overvoltage causes the controller to disconnect solar energy charging and start up the intelligent wind turbine shut-down system.
电池指示
Power
Power indicator: Turns on after controller is connected to chargeable battery.

Installation instructions
 Cautions
1.No exposure to rain.
2.Vertical hanging for installation.
3.Make sure the polarity of chargeable battery, load and photocell board is not reversed
4.Load power should not exceed rated power or current.
5.Keep good ventilation of controller for radiation.
6.Regular inspection of working condition of controller in case of adverse impact.

Installation procedures
1.Check whether the voltage and power of the controller matches with those of wind turbine, solar array and chargeable battery.
2.Set operating mode in accordance with service condition. Please refer to mode setting.
3.Check with universal electric meter whether the voltage of battery packs is correct and confirm anode and cathode of battery pack.
4.Connect chargeable battery pack to controller.
5.Connect applicable direct current load or lamps to controller (Please mind the polarity!).
6.Connect wind turbine to controller (It is not advisable to install while wind turbine is at high rotary speed. Connect when not rotating).
7.Check with universal electrical meter whether voltage of photoelectrical cell unit is correct (It is normal when the open circuit voltage of photocell is 1.5 times as nominal voltage.).
8.Connect solar energy battery pack to controller (Please mind the polarity!).
9.Under twin lamp mode, lamp of short working time should be connected to load 1 and that of long working time should be connected to load 2.
