Take care when installing lead acid batteries,always wear correct safety equipment.
Keep terminals protected from foreign metal objects to ensure terminals don’t short.
Make sure battery is sufficiently ventilated
Keep battery away from open flames.
Make sure battery is protected from direct sunlight and rain/water intrusion.
Loose connections or corrosion to the terminals can cause excessive heat which may melt wiring af installation.
Always use insulated tools and keep hands dry when carrying out installation.
Always follow the safety advice given by the battery manufacturer.
Connect the controllers earth terminal to ground.
2.1 Wiring Specifications
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.

2.2 Installation and Wiring
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)
≥ 150mm

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.

DESCRIPTION
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
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
In this mode the user can switch the load on and off manually using the control keys
This mode can be used for testing the load after installation
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.

Ensure cooling fins are free of dirt or debris.
Check for any exposed wiring between solar panel and battery and also check the load if applicable.
Check that indicators are working correctly and check for fault codes in data analysis page,repair faults if recorded
Check all terminal screws are tight and that there is no corrosion on terminals and wiring
If the lightning arrestor has lost its efficiency replace with a new one in a timely manner.

When selecting User, the battery type is to be self-customized, and in this case, the default system voltage parameters are consistent with those of the sealed lead-acid battery. When modifying battery charging and discharging parameters, the following rule must be followed:
· Over-voltage cut-off voltage > Charging limit voltage ≥ Equalizing voltage ≥ Boost voltage ≥ Floating charging voltage > Boost return voltage;
· Over-voltage cut-off voltage > Over-voltage cut-off return voltage;
· Low-voltage cut-off return voltage > Low-voltage cut-off voltage ≥ Discharging limit voltage;
· Under-voltage warning return voltage > Under-voltage warning voltage ≥ Discharging limit voltage;
· Boost return voltage > Low-voltage cut-off return voltage
