The solar controller requires power from the battery in order for it to operate (9-14 volts) .  The first step in troubleshooting any solar controller is to determine if you have 12 volts to the controller.  This is done by measuring the input from the battery on the back of the controller.  If the battery voltage is below 9 volts it will not power the controller.  Check the inline fuse between the battery and the controller and your battery and terminal block connections on the controller. 

 

If the controller is in an error state first try a soft reset.  This is done by holding down all 4 buttons on the front of the controller for 15 seconds.  If this does not work a hard reset is required.  Remove all 4 wires from the back of the controller for 15-20 minutes, then reconnect the wires.  Determine if this clears the error state.
