Yes, totally agree, one needs Redundancy on board. That's why this unit is only an Inverter and used for a specific use on board.

I Just would like to get my hands on the Schematics for this unit to fix it, nothing , unbelievable!

Yes, Agree with that. I have used Victron with a few vessels and have had No trouble what so ever, will be going back to them for a new Inverter. In Australia I am so amazed that Mastervolt Distributors will Not even repair their goods after 10 years of service, they say buy a new one! Cheers.

Hi All, See below for the problem that now exists. No spares, no schematics, no service manuals, no support, I have tried all over the globe, no information is being given out. Seems they love their product , ive repaired the latest damage,, and the unit will now turn on and stay on,,, but the overvoltage is on all the time,, indicating an output stage or control issue ive tested components in output stage,, all good, i need schematics to go any further, has any one got any drawings of the control stage?

Had a problem again, the same part has blowen again, C30 , 1μF (105) ceramic capacitor, when I connected to the 12 volt DC battery supply, the inverter was Not Turned On on it's on/off switch and had no load connected on the 240V AC outlet. I can't see any other problems and have no ideas, has any one found any schematic drawings or any suggestions ?

Finished the repair with new part and all checked, works again, thanks to all for your help,Great!

Yes, Too Right and correct. I have been trying to get info on this issue for a long time now as there isn't much info on this unit anywhere. Will see how it all goes with a replacement part and all is checked out. Cheers.

Thanks Mate, much appreciated,cheers.

Hi Dias, See photo of what you require. I need to know what is the burnt piece in my photo on my board as well thanks.
