Phoenix MultiPlus Compact 24/1600/40 goes immediately into alarm

Hi there,

Last night I noticed I did not have electricity anymore in my off-grid house. Checked the Phoenix MultiPlus Compact 24/1600/40 and the only active led was the alarm led, burning constantly.

Switched it off and on again after a few minutes, starts green with the top led and then after a few seconds, straight to the red alarm led, continuously. Had it rest for a night, tried again this morning, same thing.

Strange, has been working for years since April 2009, could usually remedy the problems but am lost now.

Any ideas? Thanks!

Stijn

To be more precise, battery at 28V measured at the terminals in the inverter, load disconnected. The charging function does not work either when I turn on the generator.

Discovered something else...with the switch in the neutral off position, the charging led comes on when I turn on the generator but it does not come on when in either other position, being inverter or charger.

Suspect that when the inverter is on and drawing/make power that the battery voltage is dropping and then you get a overload/ low voltage allarm. you must measure the voltage at the inverter itsself and take the reading just before the allarm occurs

Hi all,

So, as said, I took the Phoenix to the shop, they had a look at it and the device has a short circuit somewhere. Not repairable. They offer me a discount on a new Victron device though.

Will keep you posted.

So,

I heard back from the shop. Appears to be a short circuit on one of the boards, not repairable. Very sad but the machine had a long service life (2009).

However, they offered me a discount on a new Victron device, even when I did not buy the equipment through them. I did not even buy it myself, the previous, previous owner of my house did.

That is amazing service.

LCPower in Lisbon, Portugal for the win!
