Fig. 2.1 Installation and heat dissipation
Take care when installing lead acid batteries,always wear correct safety equipment.
Ÿ
Keep terminals protected from foreign metal objects to ensure terminals don’t short.
Ÿ
Make sure battery is sufficiently ventilated
Ÿ
Keep battery away from open flames.
Ÿ
Make sure battery is protected from direct sunlight and rain/water intrusion.
Ÿ
Loose connections or corrosion to the terminals can cause excessive heat which may
Ÿ
melt wiring af installation.
Always use insulated tools and keep hands dry when carrying out installation.
Ÿ
Always follow the safety advice given by the battery manufacturer.
Ÿ
Connect the controllers earth terminal to ground.
Ÿ
Wiring installation must comply with with national and local electrical specifications.
The wiring specifications of the battery and loads must be selected correctly to the size of
the maximum output current.
See table below for correct wiring specifications:
Risk of explosion never install the controller and
battery together in a sealed environment or any
where that battery gas may accumulate.
Solar panels connected in series will produce a high
voltage always disconnect battery whilst connecting
any wiring to controller.
When installing controller make sure it is in a well
ventilated area (see fig 2.1)
!

2.2 Installation and Wiring

3. PRODUCT OPERATION AND DISPLAY
CHOOSING AN INSTALLATION SITE
Keep controller away from direct sunlight or high temperatures.
This will ensure that you get the maximum efficiency from your controller.
Make sure area is well ventilated and away from any moisture.
MOUNTING THE CONTROLLER
Using the template provided mark 4 holes on flat surface area intended for controller.
Screw into flat surface and line up mounting holes on controller and hang controller.
BEFORE OPERATION
Make sure all connections are tight and secure and that all fuses and circuit breakers are ok.
If the LCD screen fails to turn on remove fuse from battery and check that all connections
have been done correctly.
Once LCD screen turns on manually test that the load is switching on and off manually.
When controller is charging always disconnect the load before disconnecting your
battery. This will save you appliance from any possible damage.
Within 10 minutes after the controller stops charging, reversely connecting battery will
result in damage to the controller.
Never connect an inverter directly to the load side of the controller. Always connect
your inverter directly to your battery.

This controller has 5 load operating modes which will be described below:

NO. MODE DESCRIPTION
0Solar light control
(Night time day
time load adjusting)
When no sunlight is present, after a time
delay the controller will switch the load
from solar to battery then when sunlight
emerges the controller will switch the
load back to run off the solar panel
1-14 Light control + time
control 1-14 hours
When no sunlight is present, after a time
delay the controller will switch the load
from solar to battery. the load will be
switched off after running for the desired
time set
15 Manual Mode In this mode the user can switch the
load on and off manually using the
control keys
16 Test Mode This mode can be used for testing the
load after installation
17 Normal On Mode This mode allows the load to be on
continuously 24 hours per day

4. PRODUCT PROTECTION AND MAINTENANCE
Water proof
Waterproof level:Ip32
Input power limit protection
When the solar panel exceeds the rated power the controller will limit the power of the solar
panel to the rated power to prevent any excess current damaging the controller and enter into
current- limited
Charging.
Battery reverse polarity protection if the battery is connected in reverse the controller will not
turn on as to protect the controller from component damage.
Solar input high voltage protection
If the solar panel array voltage is too high the controller will automatically Shut down the panel
input voltage.
Solar input short circuit protection
If the solar panel has short circuit the controller will stop working until The short is rectified then
the controller will start working normally.
Solar panel reverse connection
If the solar panel is reversely connected the controller will stay illuminated however there will be
no power display going to the battery The controller will go back to normal operation once the
wiring has been corrected.
Load overpower protection
When the load power exceeds the rated power value, the load will enter into delay protection.
Load short circuit protection
If the load is short circuited the controller will protect the load by shutting it down this can
happen 5 times per day without affecting the controller users can also manually address this
through accessing the abnormality codes on the system data analysis page.
Reverse charging protection at night
This function will protect the battery from discharging through the solar panel at night
Over temperature protection
When the controller temperature exceeds the set value ,it will decrease the charging power or
stop charging until the temperature has decreased, see the following diagram.

4.1 System Maintenance
To maintain the controllers performance it is recommended that the following
maintenance be carried out.
Make sure there is enough air flow around and behind controller
Ÿ
Ensure cooling fins are free of dirt or debris.
Ÿ
Check for any exposed wiring between solar panel and battery and also check the load if
Ÿ
applicable.
Check that indicators are working correctly and check for fault codes in data analysis
Ÿ
page,repair faults if recorded
Check all terminal screws are tight and that there is no corrosion on terminals and
Ÿ
wiring
If the lightning arrestor has lost its efficiency replace with a new one in a timely manner.
