Page 3: Notes, Cautions And Warnings
Notes, Cautions and Warnings This manual contains important safety, installation and operating instructions. following symbols are used throughout this manual to indicate potentially dangerous conditions or mark important safety instructions, please take note of them. WARNING: Indicates a potentially dangerous condition. Use extreme caution when performing this task.
Page 4: General Information
General Information Thank you for selecting GAMMA series solar controller that adopts the most advanced digital techniques and is fully automatic. The Pulse Width Modulation (PWM) battery charging can greatly increase the lifetime of the battery. It has various unique functions, such as: ...
Page 5: Product Features
Product Features 1. Temperature Sensor Measure ambient temperature and make temperature compensation for charging and discharging. 2. PV (solar panel) Charging Status LED indicator A LED indicator that shows charging status and also indicates warning signal when solar array connect wrongly. 3.
Page 6: Mounting Requirements
Installation General Installation Notes:  Read through the entire installation section first before beginning installation.  Be careful when working with batteries. Wear eye protection if necessary. Have fresh water available to wash and clean any contact with battery acid. ...
Page 7 Step 1: Choose Mounting Location Place the controller on a vertical surface protected from direct sunlight, high temperature, and moisture. Provide good ventilation. Step 2: Check for clearance Place the controller at the location where it will be mounted. Verify that there is sufficient room to run the wires and that there is sufficient room above and below the controller for air flow.
Page 8 Wiring NOTE: A recommended connection order (step by step) has been created to provide maximum safety during installation. NOTE: The controller is a common positive ground controller. CAUTION: Do not connect the loads with surge power exceeding the rating of the controller.
Page 9 Step1: Battery Wiring WARNING: Risk of explosion or fire! Never connect the positive (+) and negative (-) battery cables. Before battery is connected, make sure that the battery voltage is greater than 6V to start up the controller. If the system is 24V, make sure battery voltage is not less than 18V.
Page 10 Step 2: Load Wiring The controller can be connected to electrical equipments such as lights, pumps, and motors. The controller draws power from the battery. Connect the positive (+) and negative (-) controller load terminals as shown in above Figure. A fuse holder (MCB) should be wired in series with the load positive (+) or negative (-) wire as shown in above Figure.
Page 11 Step 3: Solar wiring WARNING: Risk of electric shock! Be caution when handling solar panel wiring. The high voltage from solar panel’ s can induce electric shock and injury. Keep the solar panel away from sunlight before installing the solar wiring. The controller cans accept 12V or 24V nominal off-grid solar panel(s).
Page 12 Step 4: Confirm Wiring Double-check the system wiring from step 1 through 3. Confirm correct polarity at each connection. Make sure all six terminals are tightened. Step 5: Install Fuse/Turn on MCB Install a suitable fuse in each fuse holder in the following order: 1.
Page 13 ADVANCE CHARGING TECHNOLOGY PWM Technology (Series Pulse Width Modulation) The controller adopts Advanced Series Pulse Width Modulation (PWM) technology. PWM is the most effective means to achieve constant voltage battery charging by switching the solar system controller’ s power devices. When in PWM regulation, the current from the solar array tapers according to the battery’...
Page 14 Battery Charge Information Figure: PWM charging mode Bulk Charge In this stage, the battery voltage has not yet reached the boost voltage and 100% of available solar power is used to charge the battery. Boost Charge/ PWM Regulation When the battery has been charged to boost voltage point, constant-voltage regulation is used to prevent over-heating and excessive battery gas releases.
Page 15 capacity. In float stage, loads can continue to draw power from the battery. In the event that the system load(s) exceed the solar charge current, the controller will no longer be able to maintain the battery at the float set point. Should the battery voltage remains below the boost set point, the controller will exit float stage and return to bulk charge.

and boost charge are not carried out constantly in a full charge process so as to avoid too much gas precipitation or heat generation in the battery. LED INDICATION Charging Status indicator GREEN ON whenever sunlight is available for battery charging, GREEN FAST FLASHING when system is over voltage.

Page 18 TIMER SETTING FUNCTION Dual Timer Function The default night length setting is 10 hours. The controller can learn the night period by referring the night before. It also can adapt to the different seasons (day light saving). However, it may require time to adjust and learn. Notes: When Timer 2 is disabling, the controller will turn off the load output at the sunrise time.
Page 19 3. Test Mode This mode is similar to Dusk to Dawn setting, but there is no 10 minutes delay when controller recognizes the starting voltage. When below the starting voltage, the controller will turn on the load, if higher, it will turn off load. The test mode makes it easy to check the solar lighting system during installation.
Page 20 Load Programming Mode for Timer 1 Timer 1 LED Digital No. Disable Dusk to Dawn, load will be on all night Load will be on for 1 hour (with 10 minutes delay) after dusk. Load will be on for 2 hours (with 10 minutes delay) after dusk. Load will be on for 3 hours (with 10 minutes delay) after dusk.
Page 21 Load Programming Mode for Timer 2 Timer 2 LED Digital No. Disable Load will be on for 1 hour before dawn. Load will be on for 2 hours before dawn. Load will be on for 3 hours before dawn. Load will be on for 4 hours before dawn. Load will be on for 5 hours before dawn.

TROUBLESHOOTING Protection PV Array Short Circuit If PV array short circuit occurs, clear it to resume normal operation. Load Overload If the load current exceeds the maximum load current rating, the controller will disconnect the load. The greater the overload, the faster the load will be disconnected. A small overload could take a few minutes to disconnect.
