The controller is detecting the wrong system voltage (12V instead of 24V, etc.). How can I correct this?

  • Disconnect the solar panels and batteries from the controller.
    Reconnect the batteries first, ensuring they are at the correct voltage level.
  • Reconnect the solar panels and allow the controller to auto-detect the system voltage.
  • If the problem persists, refer to the user manual for instructions on manually setting the system voltage.

The load connected to the controller is not functioning. What could be the problem?

  • Ensure the load is properly connected and within the controller’s load capacity.
  • Check for any tripped breakers or blown fuses in the load circuit.
    Verify that the load output settings on the controller are correctly configured.
  • Inspect the load device itself for any faults or malfunctions.
