3.3 Connect wires


Note:for installation safety, we recommend a wiring sequence;
Note:JND-X designed with a common negative electrode;

Warning:Do not connect the load end to the electrical equipment that exceeds the surge power of the controller to prevent damage to the controller!
Warning: make sure all wires are fixed when you need to move them around. Virtual connections can cause heat buildup, which can lead to fire

Step 1:first disconnect the controller switch(default before leaving factory is disconnect)
Step 2:connect battery
Check battery is in normal state,install as 3-2 showing,during the process, please disconnect the air switch for wiring.

Warning:All switches must be disconnected in the process of wiring, pay attention to the difference between positive and negative wires;The metal part of the cable terminal should not be exposed too long to prevent short circuit fault caused by contact with the housing after installation.
It is strictly forbidden to connect the battery with positive and negative conductor short circuit, and it is strictly forbidden to connect the photovoltaic array to the battery terminal post, please be careful to operate.
 Step 3:connect PV, battery, loads

Five Trouble Remove and System Maintenance

5.1  Protection Function

5-1 Refer to the table:
Protection Explain
Reverse polarity connection of solar panel modules When the polarity of solar panel  modules is reversed, the controller will not be charged and will not be damaged. After correcting the wiring errors, the controller will continue to work normally
PV over voltage protection When solar panel  array charging voltage exceeds the controller's rated input voltage range, it will stop charging
Reverse polarity of battery When polarity of the battery is reversed, the controller will not work and will not be damaged
Battery over discharge protection When battery voltage is lower than the set under voltage value, the battery will automatically stop the discharge, prevent the battery from excessive discharge and damage
Battery overvoltage protection When battery voltage reaches the set value of over voltage protection, it will automatically stop charging the battery to prevent the battery from overcharging and damage
Night protection At night, as the battery voltage is larger than the solar panel module voltage, automatic protection prevents the battery voltage from discharging through the solar panel module
Equipment overheating protection There is a temperature sensor inside the controller. When the temperature is higher than the set value, the charging will stop, and the temperature will automatically start and continue to work
High voltage surge  This controller can only protect high-voltage surges with low energy. In areas with frequent lightning, it is recommended to install external lightning arrester


5.2 Trouble Remove

If the following failure phenomenon occurs, please follow the following methods for inspection and troubleshooting:
5-2 Troubleshooting list                           
Error Indicator status and alarm icon Possible reasons  Solutions
Array over voltage Red light,
Icon flash
number of photovoltaic array series groups is relatively large Disconnect the photovoltaic array, reduce the number of photovoltaic array groups in series, and ensure that the open circuit voltage of the photovoltaic array does not exceed the set value in the "photovoltaic electrical parameters" table
Battery over voltage Red light,OVD and Icon flash 1.Overvoltage protection point of the controller is lower than the maximum value of the charging range;
2.Aging or over-discharge of battery;3. Battery overdischarge;
4.Large dynamic change of load
 
1. Reset the overvoltage protection point of the battery by pressing the key of the device or PC upper computer or APP;
2. Aging battery needs to be replaced;
3. Overdischarge requires manual setting of battery voltage level;
4. Reduce large dynamic changes of load;
 
Battery undervoltage Under and icon flash battery voltage value is lower than the set value of undervoltage protection 1. Reduce or disconnect the load. If the alarm is cancelled, the battery voltage returns to normal, indicating that the load power is too large or the battery voltage and capacity are too low.
2. When the load controller is disconnected, it still gives an alarm. The battery voltage has not recovered to the set value of overdischarge recovery.
 
 indicator light does not shine, the display screen does not show battery voltage is lower than the equipment starting voltage Use a multimeter to test whether the voltage at both ends of the battery is lower than 7V;
The battery group needs to be charged by other means to make its battery voltage reach more than 8V;
 
Radiator overheating Red light,
icon flash
1.High ambient temperature, poor heat dissipation of equipment, and poor fan ventilation;2. The fan is damaged
 
1.Check the installation environment of the equipment, remove sundries in the air duct of the equipment, and ensure the smooth ventilation of fans;2. Replace the fan when the fan is damaged;
Charging flow Red light,Icharge flash,icon flash Charging over current protection check current detection abnormal, wrong operation Restart several times if still can not be solved, need to return to the factory for maintenance
Load flow Red light,icon flash High load power 1. Reduce load power;
2. Restart and remove the fault;
3. No excessive sensibility and capacitive load;
 
Note:In addition to the battery voltage can not start, other faults can be referred to the PC background or mobile APP fault information;

 

5.3 System Maintenance

 In order to maintain the best long-term performance, it is recommended to conduct the following inspection twice a year.
Make sure controller is securely installed in a clean, dry environment.
Make sure airflow around the controller is not blocked and remove any dirt or debris from the radiator.
Check all exposed wires for insulation damage caused by sun exposure, friction with other objects around, dry rot, insect or rodent damage, etc.Repair or replace the wires if necessary.
Tighten screws to all electrical terminals as recommended.
Check grounding of all parts of the system and verify that all grounding wires are firmly grounded and properly grounded.
Check all terminals for signs of corrosion, insulation damage, high temperature or burning, discoloration, and tighten terminal screws to recommended torque.
Check for dirt, nesting insects and corrosion and clean as required.
If arrester has failed, replace the failed arrester in time to prevent the controller or even other users' equipment from being damaged by lightning
 

Note:Electric shock risk! ! !
Make sure all the power supply of the controller is disconnected before checking or operating accordingly!
