RS450/100 sparks

Hi,
Anybody experienced suddenly sparking sound after three months of normal function. I got a short circuit problem and recovery message in 2s at 4 pm, and all was good till the end of the sun. The following day the mppt says no PV power. Connections at the terminals are good, and there is power from PV in the cable.

Hi @Csaba Köböl,

Sorry to hear it, definitely doesn’t sound normal.

I would isolate the MPPT as best as you can (switching off external circuit protection) and get in touch with your dealer as soon as possible.
