    2 General Information 2.1 Product Overview Thank you for selecting LandStar series solar charge controller that adopts the most advanced digital technique and operates fully automatically. The Pulse Width Modulation (PWM) battery charging can greatly increase the lifetime of battery. It has various unique functions and quite easy to use, such as: High efficient Series PWM charging, increase the battery lifetime and improve the solar system performance.
  • Page 8 The controller is for off-grid solar system, especially in solar light system, and protects the battery from being over charged by the solar module and over discharged by the loads. The charging process has been optimized for long battery life and improved system performance. The comprehensive self-diagnostics and electronic protection functions can prevent damage from installation mistakes or system faults.

    3 Installation Instructions 3.1 Mounting Read through the entire installation section first before beginning installation. Be very careful when working with batteries. Wear eye protection. Have fresh water available to wash and clean any contact with battery acid. Uses insulated tools and avoid placing metal objects near the batteries.
  • Page 12 NOTE: When mounting the controller, ensure free air through the controller heat sink fins. There should be at least 6 inches (150 mm) of clearance above and below the controller to allow for cooling. If mounted in an enclosure, ventilation is highly recommended.

    3.2 Wiring NOTE: A recommended connection order has been provided for maximum safety during installation. NOTE: The controller is a common positive ground controller. CAUTION: Don’t connect the loads with surge power exceeding the ratings of the controller. CAUTION: For mobile applications, be sure to secure all wiring.
  • Page 15 Before battery is connected, make sure that battery voltage is greater than 6V so as to start up the controller. The load should be DC applicant with the same rated voltage as battery’s. Controller offers power to loads through the battery voltage. It is recommended that no less than 2 times rated current fuse is connected with battery and load.
  • Page 16 Step 1: Wiring The recommended connection order has been provided as Figure3-2 indicated. Be sure the negative and positive polarity connection is correct and all terminals are tightened. Solar Module Load Fuse Fuse Battery Figure 3-2 System wiring review Step 2: Confirm power on When battery power is applied and the controller starts up, the battery LED indicators will be on.

    4 Operation 4.1 Battery Charging Information Figure 4-1 PWM Charging mode · Bulk Charge In this stage, the battery voltage has not yet reached boost voltage and 100% of available solar power is used to charge the battery. · Boost Charge When the battery has recharged to the Boost voltage setpoint, constant-current regulation is used to prevent heating and excessive battery gassing.
  • Page 18 · Float Charge After the battery is fully charged in Boost voltage stage, the controller reduces the battery voltage to Float voltage set point. When the battery is fully recharged, there will be no more chemical reactions and all the charge current transmits into heat and gas at this time.
  • Page 19 NOTE: Equipment damage! Equalization may increase battery voltage to the level damaging to sensitive DC loads. Ensure that all load allowable input voltages are greater than the equalizing charging set point voltage. NOTE: Equipment damage! Over-charging and excessive gas precipitation may damage the battery plates and activate material shedding on them.
