Phoenix 12/1200 alternate red/green LED's

Hi, I’m trying to diagnose the problem with this Phoenix 12/1200 when switched on the red & green LED’s alternatively flash.

Is this a general alarm or does it it indicate a specific problem?

Many thanks.

Check the sequence of flashing against the error indicator chart in the user and installation manual here: https://www.victronenergy.com/media/pg/Inverter_VE.Direct_230V\_-\_HW15/en/operation.html#UUID-770be6b0-13bf-b7aa-a994-fc62fb6ae6fa

Hi Justin,

The link did not work but have found error charts but none relate to the sequence I’m seeing.

I’ve done some checks inside and the huge toroidal transformer is fine so I guess the problem is with the circuit board.

Do you know if replacement boards are available and from where?
