Hi,
I am using MPPT 100/20. Initially i connected with a 12V battery and everything worked fine. Then, i wanted to check the function with a 48V battery [My PV panel capacity - 58V]. But as soon as i connected the 48V battery, a spark came at the battery terminal and the 25A fuse in my MPPT blown off. And the app also stopped functioning. After this i replaced fuse and connected 12V battery again. Surprisingly, the fuse got blown again. When i checked in detail, seems like there is a short circuit between the battery + & - ve terminals of the MPPT (without any wires connected to battery). When the fuse is removed, however, there is no continuity between the MPPT battery + & - terminals.
Someone kindly help to understand this issue and please support to solve this issue. Can someone share the contact details of technical support team of Victron?
Thanks
Karthik
