    3.2 Wiring NOTE: A recommended connection order has been provided for maximum safety during installation. NOTE: the controller is common negative one. CAUTION: Don’t connect the loads with surge power exceeding the ratings. CAUTION: Secure all wiring for mobile applications. Use cable clamps to prevent cables from swaying.
  • Page 15 It is suggested that positive pole or negative pole of battery and loads be connected to a safety device whose operation current is not twice lower than nominal charging or discharging current. Do not switch on the safety device while it is being installed.
  • Page 16 Step 1: Wiring and switching on After solar system is wired, check all wirings carefully to make it clear whether all 6 terminals are connected correctly and tightened. According to the order of switching on in the chart, battery first, loads second and solar module third successively to avoid nominal system voltage identification error.

  • Page 17: Functions

    4 Functions 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 18 When the battery has recharged to the Boost voltage set point, constant- current regulation is used to prevent heating and excessive battery gassing. The Boost stage remains 120 minutes and then goes to Float Charge. Every time when the controller is powered on, if it detects neither over discharged nor overvoltage, the charging will enter into boost charging stage.
  • Page 19  Equalize Charge WARNING: Risk of explosion! Equalizing flooded battery can produce explosive gases, so well ventilation of battery box is necessary. 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.
