User Manual
I.main feature
1. High efficiency booster MPPT charging ways.
2. The system uses solar panel power supply, reduce the
power consumption of the battery.
3. The LED status indicator，running status be clear at a
glance.
4. The digital tube displays the charging current, battery
voltage and photovoltaic panel input voltage in real
time.
5. Complete over-charge, anti-recoil, anti-reverse, and
short circuit protection.
6. One-click set battery voltage grade (48V, 60V, 72V
three battery voltage grade easy one-click settings).
7. The charging constant voltage point can be set,
compatible with common lead-acid batteries and
lithium batteries on the market.
8. System operation design is simple, easy to use, safe
and reliable.
II.Installation and wiring
1. Dimensional drawing：Dimensions :115×111×43(mm)
Installation size：（55~95）
×103(mm)
Install Aperture：3.5(mm)
2. Port description: solar and battery end baffle
instruction：
Solar End stop
Battery End stop
3. Connect the "+" polar line of the photovoltaic panel to
the red line (or brown line) on the solar end of the
controller (the silk screen is the photovoltaic panel end),
please do not connect it in reverse. The cable on the
solar (photovoltaic panel) end is φ10mm, battery The
(battery) end cable is φ8mm. )
4. Connect the "-" terminal of the photovoltaic panel to the
black line (or blue line) on the solar end of the
controller.
5. Connect the (+) pole of the battery to the red wire (or
brown wire) on the battery end of the controller.
6. Connect the (-) pole of the battery to the black wire (or
blue wire) on the battery end of the controller. After the
wiring is normal, if there is sun, the controller will start to
work.
7. The wiring diagram is shown below：

III.Use advice
1. Please do not overload use the controller, 18V PV
panels maximum power is 200W, if you have two
pieces of 18V PV panels ‘s total power above 200W
please in series use them;36V PV panels maximum
power is 400W, if more than 2 pieces PV panels,please
used them in parallel.(PV panels parameters: 18V PV
panel’s working voltage is 18 v, open circuit voltage is
22V, 36V PV panel’s working voltage is 36V,open circuit
voltage is 44V. please look at the PV panels on the
back of the parameters then connection it.)
2. The controller will heat during operation, please
installed in the ventilation and heat dissipation of the
environment.
3. It is recommended to install an air switch on the battery
and photovoltaic side when the system is connected,
otherwise a fire will occur during the connection, which
may damage the controller or other equipment.
4. The input and output of the system are isolated. Do not
share the negative pole and never share the positive
pole.
5. The battery cannot work or store under voltage, and it
should be fully charged at least once a month,
otherwise the battery will suffer permanent damage.
Only when the energy entering the battery is more than
the energy used by the load can the battery be fully
charged. Users should keep this in mind when
configuring the system.
IV.system operation and status indication
1. After the system is connected normally, if the
photovoltaic panel voltage reaches the controller's
starting voltage and starts to start, the LED will light up
after the LED flashes 3 times and the controller will
start.
2. After the system is started, the digital tube displays the
battery voltage, the photovoltaic panel input voltage,
and the charging current.
3. Status indication, as shown in the following table：

4. parameter settings：
4.1 Voltage level setting：After the PV is started, press
and hold the "set" button for 5 seconds and release it to
enter the battery voltage level setting interface,Press the
"set" button to cycle through the "H48.F", "H60.F", and
"H72.F" interfaces in sequence, corresponding to 48V, 60V,
and 72V voltage levels, respectively.After setting the voltage
level, release the button for 5 seconds to return to the main
interface after setting the voltage level.The setting interface

is as follows：
4.2 Constant voltage point setting：After the PV is started,
press and hold the "set" button for 10 seconds and then
release it to enter the constant voltage value setting
interface of the current voltage level.Each time you press
the "set" button, the value increases by 0.1V, and it
automatically enters the minimum value when it exceeds
the maximum value.Set the over-voltage protection value.
Release the button for 5 seconds to return to the main
interface. The constant-voltage setting is completed. The
default constant-voltage value setting interface for each
voltage level is shown in the figure below.：
48V
60V
72V
V.safety recommendations
1. The controller can be adaptive to the 12V and 24V PV
panels, please do not use the open circuit voltage
above 50V PV panels,otherwise there will be the risk of
burning.
2. The controller inside not have the parts need to
maintain and repair, and contains safe voltage higher
than the human body, please don't take apart the
controller.
3. Please do not use water or corrosive liquids into the
controller, and they might damage the controller.
4. Battery 48V, 60V or 72V, battery terminal voltage are
both more than the human safety voltage,when you
operation it, pay attention to use insulated tools, and
maintain the necessary dry.
5. The battery connect reverse or short circuit, the current
is large, the controller will not damage, but the fuse will
melt,accompanied by strong spark phenomenon at the
same time,this time the impact on the battery and your
equipment are high, please try to avoid the happening
of this kind of situation.
6. The battery may produce flammable gas, please stay
away from sparks.
VI.Technical parameters
Warranty commitment：The company promises that the
machine is free for one year and lifetime
maintenance.Damage beyond the warranty period or
damage caused by force majeure such as
transportation, improper use, or man-made damage, or
natural disasters are not covered by the warranty.If
there are special instructions in the contract, the
contract content shall prevail.
