2.Safety instructions and waiver
of liability
2.1 Safety
①The solar charge controller may only be used in
PV systems in accordance with this user manual
and the specifications of other modules
manufacturers. No energy source other than a solar
generator may be connected to the solar charge
controller.
②Batteries store a large amount of energy, never
short circuit a battery under all circumstances.
We strongly recommend connecting a fuse
directly to the battery to protect any short circuit
at the battery wiring.
2.2
③Batteries can produce flammable gases. Avoid
making sparks, using fire or any naked flame.
Make sure that the battery 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.
Page1/13 Pages
3. Optional
3.1 Remote display unit
Remote display unit can display system information,
failure information and one year's charge and discharge
data.
3.2 Remote temperature sensor
Acquisition the ambient temperature of the battery, which
can be accurate compensation charge values, standard
wire length is 2 meters (can also be customized according
to user needs).

5.3 Preparation of wiring
5. Installation
5.1 Mounting location requirements
Do not mount the solar charge controller outdoors or in wet rooms. Do not subject the solar charge controller to
direct sunshine or other sources of heat. Protect the solar charge controller from dirt and moisture. Mount upright
on the wall on a non-flammable substrate. Maintain a minimum clearance of 10cm below and around the device to
ensure unhindered air circulation. Mount the solar charge controller as close as possible to the batteries.
5.2 Fastening the solar charge controller
Mark the position of the solar charge controller fastening holes on the wall, drill 4 holes and insert dowels, fasten
the solar charge controller to the wall with the cable openings facing downwards.
5.4 Connection
We strongly recommend connecting a fuse directly to the battery to protect any short circuit at the battery wiring.
Solar PV modules create current whenever light strikes them. The current created varies with the light intensity,
but even in the case of low levels of light, full voltage is given by the modules. So, protect the solar modules from
incident light during installation. Never touch uninsulated cable ends, use only insulated tools, and make sure that
the wire diameter is in accordance with the solar charge controller’s expected currents. Connections must always
be made in the sequence described below (Figure 3: System wiring diagram).

5.5 Grounding
Be aware that the positive terminals of the controller are connected internally and therefore have the same
electrical potential. If any grounding is required always do this on the positive wires.
!Remark: If the device is used in a vehicle which has the battery negative on the chassis, loads
connected to the controller must not have an electric connection to the car body, otherwise the low voltage
disconnect and electronic fuse functions of the controller are short circuited.

①②
③④⑤⑥
1st step: Connect the battery
Connect the battery connection cable with the correct polarity to the middle pair of terminals on the solar charge
controller (with the battery symbol). If the system is 12V, please make sure that the battery voltage is within
10V~16V, else if the system is 24V, the battery voltage should between 20V~30V. If the polarity is correct, the
LCD screen on the controller will begin to show.
2nd step: Connect the solar module
Ensure that the solar module is protected from incident light. Ensure that the solar module does not exceed the
maximum permissible input current. Connect the solar module connection cable to the correct pole of the left pair
of terminals on the solar charge controller (with the solar module symbol).
3rd step: Connect loads
Connect the load cable to the correct pole of the right pair of terminals on the solar charge controller (with the
lamp symbol). To avoid any voltage on the wires, first connect the wire to the load, then to the controller.
4th step: Final work
Fasten all cables with strain relief in the direct vicinity of the solar charge controller (clearance of approx.10cm).

“I in” shows the charging current at the moment. When the voltage of the battery is
getting near the final charge voltage, the solar charge controller will regulate the “I
in” in order to protect the battery from being overcharged. The charge current “I in”
is lower than the module current.
“Temp” displays the environment temperature of the solar charge controller.
The solar charge controller status such as "Fast charging", "Equal charging”, ”Boost
charging”, ”Float charging” and "No Charging” indicate which stage of charging is in
process. After a certain period of time of operation in the “Boost” and “Equal”
charging modes, the “Float” charge mode is resumed.
The content displays the current load state, “Load on” means the load has been
opened, “Load off” means the load is in a closed state.
“SOC” means "state of charge" and indicates how much remaining capacity the battery still has. The SOC is
never 100% as due to technical reasons it is easier to indicate a two-digit number.
“BAT” shows the battery's actual voltage.
“IN” is the sum of the charging currents flowing into the battery.
“OUT” is the sum of discharge currents flowing out of the battery.
The second line constantly changes its information. All values and system information are indicated alpha-
numerically. The following displays can only be seen during regular operation (not while programming).
“I accu” is the balance of all charging and discharging currents. As long as the
charging current is higher than the discharging current, the value is position, in the
opposite case, it is negative.
6.Indication of Status
The two-line display indicates all present system values in short form on the top line, and the values are without
units (Volt, Amp, etc) due to a lack of space. The printing above each value serves as a reminder:

8 Safety Measures
We urgently recommend the installation of a safety device on the battery pole in order to prevent damage from
short circuits between battery and the solar charge controller.
8.1 Electronic Short Circuit Safety
An electronic short circuit safety device is built into the solar charge controller and prevents both destruction of
the solar charge controller and the blowing of the safety fuse in case of short circuits on the load terminals. The
second line of the LCD display indicates this error as "Short circuit". After elimination of this fault, the solar charge
controller automatically switches back to normal operation after about 60 seconds.
8.2 Hardware Safety
In addition to the electronic fuse device mentioned above, the solar charge controller has also been protected
by regular fuses which have been rated far beyond nominal currents to prevent false blowing of the fuses during
surges. The safety fuses are wired in parallel. In order to prevent fuses from blowing in the case of high currents
over a short period of time, a high value has been selected. Before the fuses blow, the electronic safety fuse
should prevent any excessive current flow.

9 Malfunctions and Errors
The solar charge controller is protected against damage by various measures. Nevertheless, always take utmost
care in the proper operation of the solar charge controller. Short hints of the malfunctions are indicated with the
help of the LCD display. However, errors are only properly indicated in which the system has been properly
installed. If there are other malfunctions than the ones described below, please check first of all if the solar charge
controller has been connected to the battery, the module and the loads correctly in the right polarity. Afterwards,
check the safety fuses.
Short circuit
Remedy
Battery has low capacity. To protect the
battery, all loads powered by the solar
charge controller will be disconnected.
• Reduce loads or hours of operation of loads
to keep the battery from being discharged
deeply, or increase solar array to add
energy to the system.
• Connect all loads through the controller to
avoid strong discharge of the battery.
• It will restore only when the battery being
recharged and the voltage reaching the
reconnect voltage.
Low voltage
Over heat
The maximum allowable temperature has
been exceeded. In order to reduce further
heat generation the loads are disconnected
automatically. As soon as the solar charge
controller has cooled down, normal
operation will resume.
• Check the ventilation at the back heat
sink and clean it if necessary.
• Protect the controller from direct sunshine.
• Reduce warming caused by appliances
near the controller.
• Reduce the loads or PV modules.
In particular, the recharge process through
back-up generators or chargers tied directly
to the battery causes battery voltages
higher than 16.5V/33.0V.
Disconnect external chargers, when the
controller automatically restored.
battery voltage is lower than 15.5V/31.0V
• There is no voltage feed from the battery.
• current operating temperature is too high
or too low above/below the operating
temperature, causing LCD not to function.
• Check the battery connections and fuses.
• Check the working temperature.
• Reinstall the controller, disconnect
everything and connect it again in the
right order.
Over voltage
LCD has no
display
The load current is too high and the
output is disconnected. Either the whole
consumption exceeds the max. discharge
currents or the max. Pulse currents were
exceeded by using high surge appliances.
Switch off all loads. Remove the fault,
the controller will switch on load
automatically after 1 minute.
