Page 8: Mounting
3.2 Mounting 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. -

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. - Page 10 Fuse Battery Figure 3-2 Battery connecting Before battery is connected, make sure that battery voltage is greater than 6V so as to start up the controller. If system is 24V, make sure battery voltage is not less than 18V. System voltage can only be automatically recognized when controller start up for the first time.
- Page 11 Connect the positive (+) and negative (-) of loads to controller load terminals as shown in Figure 3-3. The load terminal may exist voltage, connect carefully to avoid short circuit. An in-line fuse holder should be wired in series in the load positive (+) or negative (-) wire as show in Figure 3-3.
- Page 12 Step 4: Confirm Wiring Double-check the wiring in step1 through 3. Confirm correct polarity at each connection. Verify that all six terminals are tightened.

4 Operation 4.1 PWM Technology (Series Pulse Width Modulation) The controller adopts the advanced series pulse width modulation (PWM) charging mode. With range of 0-100%, it can charge the battery quickly and stably under any condition of solar photovoltaic system. PWM charging mode use automatic conversion duty ratio pulses current to charge the battery. - Page 14 ·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.
