3.3 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 11 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 12 If wiring the load connection to a load distribution panel, each load circuit should be fused separately. The total load draw should not exceed the load rated current of controller. Step 3: Solar wiring WARNING: Risk of electric shock! Exercise caution when handling solar wiring.
- Page 13 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 to 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 15 · 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.

Certain types of batteries benefit from periodic equalizing charge, which can stir the electrolyte, balance battery voltage and complete chemical reaction. Equalizing charge increases the battery voltage, higher than the standard complement voltage, which gasifies the battery electrolyte. If the battery is being over discharged, the solar controller will automatically turn to equalize charging stage, and the equalize stage remain 120mins. - Page 17 Battery Status indicator GREEN ON when battery voltage in normal range GREEN SLOWLY FLASHING when battery full ORANGE ON when battery under voltage RED ON when battery over discharged Please refer to section 5 for troubleshooting.
