Quattro 12/5000/120 Burning Smell, now won't turn on

HI All,

I was charging my batteries on my boat today, as usual. Noticed a burning smell, and traced to the inverter area. I turned off the generator input, and all conntinued fine, the smell went away.

I tried re applying the genset input, and the unit tried to switch from Inverting to Bulk, and seemed to fail. The was a fairly loud switching noise (may be normal) and the unit turned off. It seemed to restart, and the Float and Temp led's flashed for a second, and the attempt to change to Bulk restarted, and failed again in this loop. I turned off the genset input again, and now the unit is dead, it wont turn on at all.

Can anyone please help with any basic troubleshooting, or is this likely a pro service job?

Product:
Quattro 12/5000/220-100/100 120V VE.Bus

SKU:
QUA125021100

Serial number:
HQ2105MBVP2

Complaint:
Reason for return:
Report from client:

While our Trawler was underway. I had the Generator running while Master-Slave Quattro’s were charging Lithionics ESS system. The alternator was derated for 50% output contributing 180 DC Amps to the charging as well when the Master Quattro failed. Burning smell detected by my wife while handling lines outside. I mediately isolated the DC input to the Master Inverter. I have configured the Slave as a stand-alone to charge the Lithium however I had to send the Master Quattro in for repair. I see that I'm not the only one struggling with this issue.

I was running current firmware

Installation date: 2021-06-25
Failure date: 2022-08-23
Firmware update: Current
Installed firmware version: V497
Warranty claim: yes
Is there a follow-up by Victron on this issue. I have concerns that my Slave may fail as well.

Zombonz,

How did you resolve your Quattro catastrophic/burn failure?

you will need to return it to the dealer you purchased it off as by the sound of your issue it will need repairing

Thanks. I realise that is likely the obvious answer, but that is not possible for me, as I am half way around the world from the original dealer. But yes I suppose it does need to be looked at by Victron. I am detecting 13v input from battery but unit is not powering on. I had hoped there was a fuse somewhere that might be a culprit to start with, but it appears not. Thanks for taking the time. Cheers

Hi,

Did you ever find the source of a problem or solution? We seem to be having a similar issue.

Same problem here, Generator charging, sweet smell in the engine room, Quattro turned itself off and cannot be restarted within the warranty window. The original dealer asks to send the unit back for repair. The boat is in the West Indies, and the dealer is in the US Arizona. Near impossible to ship from here, hurricane season prevents sailing any closer, if that is even possible with degraded charging capabilities. It needs to have at minimum a warranty transfer to a dealer close to where the defective device is.

Contact a dealer closer. Explain the situation.

At the end of the day Victron is Victron - and the dealer gets parts under warranty (if approved) from them.

Usually there are side costs incurred by the non OG dealer like admin fees and maybe shipping something the original point of purchase. Be prepared to pay for that, the service is there.
