1. PRODUCT INTRODUCTION
Ÿ This product is designed to monitor a solar panel's generated power, tracking the
highest voltage and current values in real time. This allows the charging of your battery to its highest potential, enabling the maximum power output.
Ÿ Can be used on all types of solar panels. Ÿ The product features an easy to read LCD display allowing you to check and adjust
parameters by using the direction keys below the screen. This also allows you to modify your controller to best suit your system.
Ÿ With built-in diagnostics technology, the controller is able to identify faults and
display error codes for ease of troubleshooting.

2. INSTALLING CONTROLLER
Ÿ 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
melt wiring.
Ÿ 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.
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 where battery gas may accumulate.
Solar panels connected in series can 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)

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, 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 made correctly. Once LCD screen turns on manually test that the load is switching on and off.
When controller is charging, always disconnect the load before disconnecting your battery. This will save your controller 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, fridge, or other accessory requiring consistent, reliable power directly to the load side of the controller. Always connect your inverter and accessories directly to your battery, fused appropriately.
