  • Page 10: Installation Instructions

    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.
  • Page 11 Step 1: Choose Mounting Location Locate the controller on a vertical surface protected from direct sun, high temperature, and water. And make sure good ventilation. Step 2: Check for clearance Place the controller in the location where it will be mounted. Verify that there is sufficient room to run wires and that there is sufficient room above and below the controller for air flow.

  • Page 12: Wiring

    3.2 Wiring NOTE: A recommended connection order has been provided for maximum safety during installation. NOTE: There are two types of the controller: common positive controller and common negative controller. CAUTION: Don t connect the loads with surge power exceeding the ratings of the controller.
  • Page 13 Controller s load terminals can be connected to DC electric equipments whose nominal operation voltage is the same as nominal voltage of battery. The controller supplies power to loads with battery voltage. It is suggested that positive pole or negative pole of battery and loads should be connected to a safety device, whose operation current is not twice lower than nominal charging or discharging current.
  • Page 14 Step 1: Wiring and switching on After solar system is wired, check carefully all wirings so as to make it clear whether all 6 terminals are correctly connected 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 15: Operation

    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 16 ·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. Every time when the controller is powered on, if it detects neither over discharged nor overvoltage, the charging will enter into boost charging stage.
