3. INSTALLATION
3.1 Unpacking and Inspection
Before installation, please inspect the unit. Be sure that nothing inside the package is
damaged. You should have received the following items inside of package:
Solar charge controller×1
User manual×1
Communication cable×1
Battery Temperature Sense×1
Software CD ×1
3.2 Preparation
Before connecting all wirings, please take off wiring box cover by removing screws
as shown below.
3.3 Mounting the Unit
Consider the following points before selecting where to install:
This solar charge controller is designed in IP20 for indoor applications only.
Do not mount the unit on flammable construction materials.
Mount on solid surface
Install this charger at eye level in order to allow the LCD display to be read at all times.
For proper air circulation to dissipate heat, allow a
clearance of approx. 300 mm to the side and approx.
300 mm above and below the unit.
The ambient temperature should be between -10℃and 55℃
to ensure optimal operation.
The recommended installation position is to be adhered to
The wall vertically.
Install the unit to the wall by screwing two screws.
Refer to right chart.
3.4 Power connection
Wire size
The four large power terminals are sized for 14-2AWG(2.5-3.5mm2) wire. The terminals are rated
for copper and aluminum conductors. Use UL-listed Class B 300 Volt stranded wire only. Good
system design generally requires large conductor wires for solar module and battery connections
that limit voltage drop losses to 2% or less.
Minimum Wire Size
The table below provides the recommended minimum wire size allowed for the charger. Wire
types rated for 75℃and 90℃are listed.
Recommended wire size:
Typical Amperage

Overcurrent Protection and Disconnects
CAUTION: Circuit breakers or fuses must be installed in both battery and solar circuits.
The battery circuit breaker or fuse must be rated to 125% of the maximum current or more. The
recommended breaker/fuse rating for use with the charger is listed in the below table.
recommended breaker rating:
Minimum battery circuit breaker / fuse rating
1.25×80Amps=100.0Amps
A disconnect is required for the battery and solar circuits to provide means for removing power
from the charger. Double pole switches or breakers are convenient for disconnecting both solar
and battery conductors simultaneously.
Connect the Power Wires
WARNING:Shock Hazard
The solar modules can produce open-circuit voltage in excess of 100Vdc when in sunlight. Verify
if solar input breaker or disconnect has been opened(disconnected) before connecting system
wires.
（common negative）
Connect terminals by following below steps(Refer to diagram above):
1. Make sure that the system input and output disconnect switches are both turned off before
connecting power wires to the charger. There are no disconnecting switches inside the charger.
2. Make 4 power wires first. Remove insulation sleeve 10.5mm and the conductor should be
plated Tin.Refer to the chart below.
3. Pull all wires into the wiring box. The Remote Temperature Sensor and Battery Sense wires
can be inside the conduit with the power conductors. It is easier to pull RTS and Sense wires
before the power cables.
WARNING:Risk of Damage
Be sure that the battery connection is made with correct polarity. Turn on the battery
breaker/disconnect and measure the voltage on the open battery wires BEFORE connecting to the
controller. Disconnect the battery breaker/disconnect before wiring to the controller.
4. Connect positive terminal(+) of battery to the battery positive terminal(+) on the controller.
5. Connect negative terminal(-) of battery to one of the common negative terminals(-)on the
controller.
WARNING:Risk of Damage
Be sure that solar connection is made with correct polarity. Turn on the solar breaker/disconnect
and measure the voltage on the open battery wires BEFORE connecting to the controller.
Disconnect solar breaker/disconnect before wiring to the controller.
6. Connect positive wire(+) of solar module to the solar positive terminal(+) on the controller.
7. Connect negative wire(-) of solar module to one of the common negative terminals(-)on the
controller.
8. Screw four(4) power terminals tightly with 50 in-lbs torque.(5.65Nm)
3.5 Grounding and Ground Fault Interruption
Use a copper wire to connect the grounding terminal in the wiring box to earth ground. The
grounding terminal is identified by the ground symbol shown below that is stamped into the
wiring box just below the terminal:
The minimum size of the copper grounding wire is 8AWG(10mm2).
WARNING:Risk of Fire
Do NOT bond system electrical negative to earth ground at the controller.
3.6 Battery Temperature Sensor
The included Battery Temperature Sensor(BTS) is recommended for effective temperature
compensated charging. Connect the BTS to the 2-pole terminal(see figure as below). The BTS is
supplied with RJ11,33ft(1m) of 22AWG(0.34mm2) cable.
NOTE: The BTS is optional package. Please check local dealer for the details.
CAUTION: The controller will not activate temperature compensate charging function if the BTS
is not used.
CAUTION:Equipment Damage
Never place the temperature sensor inside a battery cell. Both the BTS and the battery will be
damaged.
NOTE: The BTS cable may be shortened if the full length is not needed.
3.7 Communication Connections
The default Communication of the controller is RS485 port. You can use supplied cable to connect
RS-485,USB port of controller to PC. It can be used for monitoring or upgrade the fireware in
short distance.
Insert bundled software CD into a computer and follow on-screen instruction to install the
monitoring software. For the detailed software operation, please check user manual of software
inside of CD.
4.OPERATION
4.1 Power-up
WARNING: Risk of Damage
Connecting the solar module to the battery connector will permanently damage the controller.
Confirm that the solar and battery polarities are correctly connected to the controller.
A battery must be connected to the controller before operating it. The controller will not
operate only with solar input. Solar input can trigger the controller to start up when the
battery is connected without pressing the button.
Turn on battery disconnect switch first. And press operation button for a while. Then , it will
indicate a successful start-up in LCD display.
Turn on solar disconnect switch. If the solar module is in full sunlight, the controller will
begin charging.
4.2 Operation and Display Panel
The operation and display panel, shown in below chart, is on the front panel of the controller. It
includes three indicators, one operation button and a LCD display, indicating the operating status
and input/output power information.
