2.1 Safety
①The solar charge controller may only be used in PV
systems in accordance with this user manual and the specs
of other module manufacturers. No energy source other
than solar gen. may be connected to the solar charge
controller.
②Batteries store a large amount of energy, never short
circuit a bat. under all circumstances. We strongly
recommend connecting a fuse directly to the battery to
protect any short circuit at the bat. wiring.
2.2
③Batteries can produce flammable gases. Avoid making
sparks, fire or any naked flame. Make sure that the bat.
room is ventilated.
④Avoid touching or short circuiting wires or terminals. Be
aware that the voltages on special terminals or wires can
be as much as twice the battery voltage. Use isolated tools,
stand on dry ground, and keep your hands dry.
⑤Keep children away from batteries and the charge
controller.
Liability Exclusion
The manufacturer shall not be liable for damages, especially
on the battery, caused by use other than as intended or as
mentioned in this manual or if the recommendations of the
battery manufacturer are neglected. The manufacturer shall
not be liable if there has been service or repair carried out
by any unauthorized person, unusual use, wrong
installation, or bad system design.
1.As the chart, connect the load with the corresponding
brown(positive) and blue(negative) cables firstly, then
seal them with tape.
2.Connect battery with the corresponding red(positive)
and black(negative) cables. Load will be on after 5s.
3.Connect panel with the corresponding red(positive)
and black/green( negative) cables, the load will be off
after 5s,and the controller begins charging.
4.Refer to 11.LED indications and Faults & Alarms to
confirm the LED display status.

4.2.3 Exit the transportation mode
When the load is properly connected, press the test key
or connect the solar more than 1s during daytime , the
transport mode will terminate and the controller will
work normally.
4.2 Transportation mode
The controller is generally integrated with the lithium
battery in the lithium battery pack for transport, if the
controller works normal during transport, it will waste of
energy and increase the transport risk. If the controller is
set to transport mode, the load has no output, then the
power consumption is reduced by about 60%, to avoid
lithium battery voltage too low.
4.2.1 Open circuit protection
If the controller is only connected with the battery, but
not connected with solar and load, the controller will
enter transportation mode after 5 minutes.
4.2.2 Press the "Test" key in transport mode
Press the "Back" and "Backlight" key at the same time
more than 3s, the remote controller will work in transport
mode.
Press the "Test" key in the transport mode, the remote
controller displays "Transport OK" and will beep a long
sound, the controller enters into transport mode.

6.Starting up the controller
6.1 Self Test
As soon as the controller is connected to battery, it starts
self test. Then the display changes to normal operation.
6.2 Battery Type
MPPT-DC series controller applies to single Lithium
rechargeable battery.
6.3 0℃ Charging Protection
"0℃ Chg" can be set to "Yes", "Slow" or "No". When the
controller detects that the ambient temperature is higher
than 0℃, the charging function is normal. when the
ambient temperature is low than 0℃, if the "0℃ Chg" is
set to "Yes", the charging function is normal, else if the
"0℃ Chg" is set to "slow", the max charging current is
20% of the rated current, else if the "0℃ Chg" is set to
"No", the controller does not charge the battery.
The user can select the appropriate charging method.

8.LVD, LVR, Threshold, Dimming
!1. Day/Night threshold voltage should be set around
0.1 times of open circuit voltage.
2.Day/Night threshold voltage of load disconnect is 0.3V
higher than the setting data, means the load will
disconnect when the solar voltage at 1.3~3.3V.
3.The controller has an automatic day/night threshold
adjustment function. If the lowest voltage of solar array is
higher than the setting day/night threshold, the load has
no output in first night, 24 hours later the controller can
automatically adjust the day/night threshold to meet the
requirements of lighting at night.

recovery voltage.
2.LVR should be higher than LVD at least 0.2V.

8.3 Day/Night Threshold, Day/Night Delay
The controller recognizes day and night based on the
solar array open circuit voltage. This day/night threshold
can be modified according to local light conditions and
the solar array used.
Day/Night threshold setting range: 1.0~3.0V.
In the evening, when the solar array open circuit voltage
reaches the setting day/night threshold, you can adjust
the day/night delay time to make the load turn on a little
later.
Day/Night delay time setting range: 0~30min.
8.4 Auto Dimming
The "Dim Auto" item of SU/SG32 set "Dim V"
and "Dim %" at the same time, press the "Send" key to set
up the controller. when the battery voltage is lower than
the voltage of "Dim V" , it starts to dimming automatically.
Battery voltage reduces per 0.1V, load current decreased
