    Installation WARNING Connect the battery to the charge controller BEFORE connecting the solar panel(s) unless you have the solar suitcase with controller exception. The controller needs a stable power source to operate. CAUTION Do not over-torque or over tighten the screw terminals. This could potentially break the piece that holds the wire to the charge controller.

  • Page 9: Wiring And Fusing

    Wiring and Fusing The wire terminals are closed by default. NOTE Use bare wiring when connecting to the Wanderer’s terminal blocks. Due to default positioning, you must ensure that the terminal hatch is completely open before the first-time use. 1.Make sure to rotate the hatch counterclockwise (CCW) into the open position to expose the wire hatch 2.Insert bare wire into the terminal for the respective connection...

    Four Charging Stages The Wanderer has a 4-stage battery charging algorithm for a rapid, efficient, and safe battery charging. They include: Bulk Charge, Boost Charge, Float Charge, and Equalization.
  • Page 18 Bulk Charge: This algorithm is used for day to day charging. It uses 100% of available solar power to recharge the battery and is equivalent to constant current. Boost Charge: When the battery has charged to the Boost voltage set-point, it undergoes an absorption stage which is equivalent to constant voltage regulation to prevent heating and excessive gassing in the battery.

    Without the wake-up feature to activate and charge batteries, these batteries would become unserviceable and the packs would be discarded. The Wanderer will apply a small charge current to activate the protection circuit and if a correct cell voltage can be reached, it starts a normal charge.

    Battery Type System Voltage Load Terminal Make sure the load is compatible with the battery type WARNING of the system. 12V loads damaged in 24V battery systems will not be covered in warranty. The Load Terminal allows you to connect DC devices directly to the controller with timer functions as optional features.
  • Page 22 Press SELECT until you highlight the Load Mode Screen where it should demonstrate a numerical load mode. The following chart indicates numbers representing hours ON that the load terminal Mode Description Setting The load will turn on at night when the solar panel is no longer producing Automatic any power after a short time delay.

    If the battery voltage is low it may be in open battery protection mode, which is a Wanderer Protection. Use a multi-meter to get a reading of the battery voltage in volts DC to validate Battery error code.
  • Page 24 Error Meaning Troubleshoot Code Load has exceeded 10Amps DC. Connect simple electronics to the load terminal and do not connect devices such as inverters, Load battery chargers, or other high amp Overloaded devices. Disconnect your load, double check the rating, and double check the correct Load Mode is on.
