Last year we bought a camper with an older Phoenix Multiplus 12/1200/50. When it is connected to the grid and switched on, the green LED lights up and after a few seconds the relay pulls and it switches to 'charger only' mode, ie the yellow LED lights up, the green LED turns off and the unit follows the grid. It then makes a slight humming sound.
However, after a few minutes the yellow LED starts to blink, mains power is still provided. The manual ( https://www.victronenergy.com/upload/documents/Manual-Phoenix-Inverter-Compact-1200-1600-EN-NL-FR-DE-ES-IT-.pdf ) only has an indication for a solid yellow LED, not blinking and we could not find any other topic in the forum. Any idea what the yellow blinking LED means ?
Many thanks.
