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. Explosive battery gasses may be present during charging. Be certain there is sufficient ventilation to release the gasses.
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. WARNING: Risk of explosion! Never install the controller in a sealed enclose with flooded batteries! Do not install in a confined area where battery gassed can accumulate.
150mm(5.9inches) Warm air 150mm(5.9inches) Cool air Figure 3-1 Mounting and cooling Step 3: Mark Holes Use a pencil or pen to mark the four (4) mounting hole locations on the mounting surface. Step 4: Drill Holes Remove the controller and drill 4mm holes in the marked locations. Step 5: Secure Controller Place the controller on the surface and align the mounting holes with the drilled holes in step 4. Secure the controller in place using the mounting screws.
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. Unsecured cables create loose and resistive connections which may lead to excessive heating and/or fire.
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.
Step 1: Wiring The recommended connection order has been provided as Figure3-2 indicated. Be sure the positive and negative polarity is correct and all terminals are tightened.

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. The Boost stage remains 120 minutes and then goes to Float Charge.
· 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. Then the controller reduces the voltage to the floating stage, charging with a smaller voltage and current.
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. Too high an equalizing charge or for too long may cause damage. Please carefully review the specific requirements of the battery used in the system.

Dusk to Dawn When solar module voltage goes below the point of NTTV (Night Time Threshold Voltage) at sunset, the controller will recognize the starting voltage and turn on the load after 10 minutes delay.
3. Test mode This mode is the same as Dusk to Dawn. 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 system installation. 4. Manual mode This mode is to turn ON and OFF the load by manual. Load Work Mode Setting Press the setting button for more than 5 seconds till the indicator flashes.

5 Protection, Troubleshooting and Maintenance 5.1 Protection · Load Overload If the load current exceeds the maximum load current rating, the controller will disconnect the load. Overloading must be cleared up through reapply power or pressing the setting button. · Load Short Circuit Fully protected against load wiring short-circuit. After one automatic load reconnect attempt, the fault must be cleared by reapply power or pressing the setting button.
5.2 Troubleshooting Trouble Shooting Table 5-1 Faults Possible reasons Troubleshooting Charging LED PV Check that PV and indicator off during array battery daytime when disconnection connections sunshine falls on wire are correct and tight. PV modules properly. Green charging Battery voltage Check if battery LED indicator fast higher than over voltage over high.

Notes: No LED indicator. Measure battery voltage with multimeter. Min.6V can start up the controller.
5.3 Maintenance The following inspections and maintenance tasks are recommended at least two times per year for best controller performance. Check that the controller is securely mounted in a clean and dry environment. Check that the air flow and ventilation around the controller is not blocked. Clear all dirt or fragments on the heat sink. Check all the naked wires to make sure insulation is not damaged for serious solarization, frictional wear, dryness, insects or rats etc.
Confirm that all the terminals have no corrosion, insulation damaged, high temperature or burnt/discolored sign, tighten terminal screws to the suggested torque. Inspect for dirt, insects and corrosion, and clear up. Check and confirm that lightning arrester is in good condition. Replace a new one in time to avoid damaging of the controller and even other equipments.
