Important safety instructions (Please keep this handbook for future
reference. Please read all instructions and precautions in the manual
carefully before installation.)
This manual contains all the safety, installation and operation instructions of this
series solar charge controller (hereinafter referred to as "controller"):
Install the controller in a well ventilated place. The controller’s case temperature may be very high
during operation. Please don’t touch the metal shell directly to prevent burns.
It is recommended to connect fuse or circuit breakers to the input, load and battery terminals to
prevent electric shock hazard during use.
After installation,check all wiring connections are secure, so as to avoid the danger of heat build-up
caused by virtual connection.
If the controller does not display properly when first use, please cut off the fuse or circuit breaker
immediately and check whether the wiring connection is correct or not.
If the solar system needs to connect the inverter, please connect the inverter directly to the battery,
instead of the load terminal of the controller.
Don’t disconnect the battery when the controller is charging. Otherwise, it may damage the DC load.
System Voltage and Battery Types
1)The controller identifies the system voltage according to the battery voltage at start-up.And the controller
will re-identify the system voltage after power-off and restart. Please confirm the system voltage displayed
in controller is consistent with the actual voltage. Otherwise, need to recheck the battery pack voltage.
Note: Please refer to Table 9 for the battery system detailed system identification voltage.
2)The controller has set 3 kinds of conventional battery charging parameters (Table 1) . To charge other
types of batteries, please select “USE” , then set up by PC software or APP. To charge lithium battery ,
please select “Lit”, then set up on the controller, APP or PC software.

1. C = Cell’s constant charging parameter.(9≤F<C≤15)
2. F = Cell’s floating charging parameter.(9≤F<C≤15)
3. N = Series number of battery.
[e.g. N=2,battery system is 24V]
4. Example:If battery system is 48V,then N=4;If the cell's
voltage C=14.6V, then Constant voltage= 14.6*4=58.4V.

5.DC Load Output Voltage and Max. Discharge Current
The controller has DC LOAD output function, and its output voltage range is the same as battery pack.
For example, if the battery’s voltage is 48.6V, the instant DC output voltage is 48.6V, too.
It can supply power to DC LOAD continuously if the DC LOAD’s current in within the rated range.
When the DC LOAD’s working current is 100%-120% of rated current for 5 minutes, DC LOAD will be
OFF.
As soon as DC LOAD’s working current is over 120% of rated current, the DC LOAD will be OFF
immediately.
To restart DC LOAD, user should set Load Type to “ON” or “USE” manually through controller/APP/PC.

Make sure that the controller is installed and connected as above
Opening process:
Step 1: open the circuit breaker on the battery side(breaker), make sure that the controller is connected
with the battery (the LCD of the controller will display the content), and set the battery type.
Step 2: if you need to use the DC load output, then set the output control mode first, and then open the

7.Communication port description
The communication port of the controller is compatible with RS485-USB communication cable for real-
time monitoring by PC software and Wi-Fi module to have remote cloud monitoring by APP.
The communication port is a standard 8 pin RJ45 interface, and the pins are defined as follows(Table 5):
Table 5 ( Figure 4 )
(Note:The pin definition is applicable to our related products ONLY!)
When the Load output is off due to the triggering protection mechanism, the dry contact output interface
is ON (low impedance). Otherwise, it is OFF (high impedance).Dry contact access voltage 5V~12V.
The controller has dual RS485 communication ports. It can be used for parallel connection.
If need to monitor multiple controllers centrally, please set the device address order (1~254) of the
controllers accordingly. For example, 5 controllers in parallel connection and monitor centrally, set
controllers’ address order as 1, 2, 3, 4, 5. (Figure 5)
If want to monitor the multiple controllers in Master-Slave communication, set the host device address to
255. For example, 5 controllers in parallel connection, just need to set the MASTER controller address
order as 255.
Warning：
If the system needs to connect the inverter, please connect the inverter directly
to the battery, and do not connect with the load end of the controller.
When the controller is in the normal charge state, do not disconnect the battery
connection, otherwise the DC load may be damaged.Therefore, the damage to
the controller will not be within the warranty.

Common Problems
Possible Reasons
Solution
Controller cannot start up,
screen can not be on
Battery positive and negative reverse
connected
Check the wiring sequence of power line
connector plug and reconnect in the right
order
Controller not charging, PV
voltage undetectable
PV Input positive and negative reverse
connected
Check the wiring sequence of power line
connector plug and reconnect in the right
order
Charging and standby keeps
circulating
Number of solar panels is too less in
series and PV voltage is low
PV Vmpp voltage must be greater than Vbat.
Please refer to the proposed series-parallel
scheme(Table 4)
It may occur in cloudy weather or in
early morning and at dusk
Normal phenomenon
Unreasonable configuration of solar
panels
Based on sufficient power, please refer to the
proposed series-parallel scheme(Table 4)
Controller is on and PV
voltage is normal, but not
charging
The controller can not recognize
battery system voltage (The “System”
in LCD flashes)
Check whether battery voltage in LCD is in
the range of controller system recognition
The battery is in a low energy
state or emptying for a long
time
Solar panels number are too less to
generate enough energy
Increase solar panels quantity
Battery capacity is too small to Store
enough energy
Increase battery capacity
