Order of connection:
1. Connect battery
Notice: The battery terminal shall be installed with insurance, and the installation distance shall not
exceed 50mm.
2. Connected Load
3. Connect PV array
4. Controller is powered on
Connect the battery identify the voltage of the control system and observe whether the display
screen is lighted. If it doesn't work or the display is abnormal, refer to section 6 for troubleshooting.
NOTICE: This series of MPPT is a common positive:
controller, PV array, battery and load of the positive pole can be grounded at the same time.
NOTICE: If the inverter or other starting current is loaded. Sin the system, please connect
the inverter directly to the battery. Do not connect with the controller's load terminal.

When the load terminal have output, this graphic symbol will be light.
14.The indicator of capacity of battery:
When the battery was in different capacity, the strip-type will show.
15.The indicator of charge status:
When the controller is charging, the symbol will be light, float charge will be flash, no charging no
display.
5 INSTALLATION IMPORTANT NOTE
1) The controller should be installed well-ventilated place, avoid direct sunlight, high temperature
and do not install in location where water can enter the controller.
2) Please select correct screw to fix the controller on the wall or other platform. Screw M4 or M5,
screw cap diameter less than 10mm
3) Please reserve enough space between the wall and controller, to allow for cooling and cable
connection.
4) The mounting holes distance is 155.8mm*63mm, diameter of the hole is 5mm.
5) Connect components to the charge controller in the sequence, please pay much attention to the
positive" and "negative", don't insert the fuse or turn on the breaker during the installation.
When disconnecting the system, the order will be reserved.
6
6) Always connect the battery first, in order to allow the controller recognize the system voltage.
7) The battery fuse should be installed as close to battery as possible.
8) The distance between the battery fuse to battery group is within 150mm
9) Positive grounding controller, any positive connection of solar load or battery can be earth
grounded as required.
10) AII terminals are in tight status after leaving factory, in order to well connected, please loose all
terminals at first.
11) The sequence of connection please do not free change, otherwise cause system voltage
recognition fault.
12) The length of cable between battery and controller as shorter as possible. Suggest 30cm to
100cm.
13) lf short circuit happened on the terminals of controller, it will be result in fire or explode. Please
be careful. (We strongly suggest to connecting a fuse at the battery side 1.5 time of rated
current of controller)
14) If the battery reverse connection, the output of controller also same with battery polarity,please
do not connect any load with controller at that time, or the load and controller will be destroyed.
15) The voltage of solar panel is very high under sunshine, high voltage can cause injury or destroy
controller, make sure PVmax under required safety MPP range.
16) Avoiding injury from load voltage, please close to the output of controller with button at first,
then connected the load on the controller. The controller do not offer reverse connection
protection for load, so please take care, reverse connection for load will be destroy bulb.
6 OPERATION STEPS
Main interface
1) The controller will have Is initialization interface after electrified, then go into main interface.

2) If no operation at main interface inner 20s, the main interface will be auto exchange during
voltage of battery, voltage of solar panel, temperature of environment, each interface keep 3s.
Long press "set" more than 5s at main interface, it will speed auto exchange. Loose button will
stop speed.
3) Press "set" under main interface could open or close
4) Press "menu' button could join into next menu under main interface.

a) Float voltage set up
This parameter is high voltage disconnection (HVD) voltage. (Boost state voltage will be increase
0.6V base on HVD). The controller will be started PWM function at this point (HVD), limited voltage
rising.
Press "menu" button join in float voltage menu.
Long press "menu" button more than 5st the parameter on the interface will be flash, here is set up
state. Loose the button, press "menu" button again could operate plus data, press "set" button
could operate minus data. After finish required technical data, long press "menu" button again more
than 5s, the parameter save and come out set up state, if 20s no any operation, automatically back
to main interface.
b) Low Voltage Reconnect Voltage (LVR)
When the voltage of battery is low, the control will stop offer power to the load. If the controller
needs reconnected the output, the voltage of battery must be higher than LVD voltage or press
'"set" button force to release, The procedure is same with (a).
c) Low Voltage Disconnect Voltage (LVD)
When the voltage of battery is low, the load output will be cut off. When the controller detected the
battery voltage was less than LVD point, the cut off function will be immediately working. At the
same time, the status of controller is in lock. Users have to charge the battery, when the battery
voltage is higher than LVD voltage or press “set" button force to release. The load output will be
back. The procedure is same with (a).
