Modular design

  • The main unit (Power Module) is a solar controller which can be integrated with different display and interface modules to meet a variety of functional requirements.
  • TRILLION controller can be widely used in RV, telecommunication base station, household system, field monitoring, etc.

Display Modular

  • Indicators: PV & battery & load working status
  • Buttons: View or set the parameters
  • LCD: PV display voltage/current /generated energy/Power Battery display voltage/current/temperature/capacity
  • Load:
  • -Display voltage/ current/ power/ load working mode when the controller communicates with the PC or APP.
  • -Display voltage/current/power consumption when the controller communicates with the inverter(only ever inverter).

UCS Module

  • USB interface module: Dual USB 5V 2.2A USB output for electronic equipment, NOTE: USB interface is output when the load is ON.
  • COM port-RS485 interface: Controller as a slave, Connect to PC or phone.
  • PC software & mobile APP (For Andriod ONLY) can remotely monitor the controller status through this port.

NOTE: PC software & mobile APP need RS485 cable or wifi box to connect your device, RS485 cable and WIFI box don't include.

  1. Turn the adjusting screw counterclockwise until the plate moves downward.
  2. Please peel off the coating of the cable tip by about 8 to 10 mm,Then Insert the wire into the new opening between the plate and the "top" of the terminal hole.
  3. When turning the adjuster clockwise, the plate moves upward and crushes the wire in the hole of the terminal.
  4. Make sure all connections going into and from the controller are tight.


  1. Make sure your battery must be at least 12V when connecting to the controller.
  2. Always connect your battery first!!!
  3. Never connect your solar panel array to the controller without a battery.
  4. Careful your input power and voltage does not exceed the max.

Please confirm the specification before instal
