Hi,
after repositioning my MPPT 75/15 and some Hardware after it, I shortened the output of the MPPT. The fuse has blown.
After I removed the short and reinstalling a new fuse, the MPPT doesn't show any output current. The load output is actually on and the devices on the load output are on.
Okay, I think the MPPT is defect now. Couse of my f****** foult I can't use the guarantee. Is there any circuit diagram availible, so that I can fix it my self?
There is no circuit diagram available.
As I can see the MPPT is fully sealed with epoxy so I don't think can get it apart without destroying it.
I made some thoughts about it. Epoxy would not be the problem for me.
I first think, that the Shunt has been blown but then I won´t have any output couse of an open circuit. I think the analog to digital converter on the µC is blown. Replacing the µC would´t be the problem for me. Those are most standardized and I have the experience to do that. The actually problem would be the software that I have to flash on on couse I don´t have it and it isn`t listed on the Homepage.
Please talk to your supplier first before attempting to open it up.
Now it shows output current. Sometimes, sometimes not...
So far I can combine it is when PVwatts are over 80W or so.
As far as I know the 2 years Warranty in Germany don't cover such stupid things I made. I ordered a new 100/20 and if it arrives the old one get on eBay.
Thanks for your answer.
Perhaps it doesn’t, but it certainly doesn’t once opened.
All Victron power electronics have a 5 year warranty,
