MArk-VI TSVO and TBAI boards capacitor burns frequently
MArk-VI TSVO and TBAI boards capacitor burns frequently.

During initial power up of MARL-VI from 125DC DCDB and through 230v AC UPS through DACA module, Capacitors C27 of TBAI modules are found getting burned. Capacitors of TSVO module are also found burned after some days of continuous operation.

Kindly suggest possible reasons of capacitor failure.

Kindly send mail reply to sdbarman [at] bheledn.co.in

Hi there,

I am experiencing the same issue with TSVO, TBAI, TRPG and TRLY capacitors burning during the first few hours of power up of mk6 panels on site. No field wiring connected to the panels yet. I'd like to understand if you were able to get anywhere with your investigation?

Presently we have no idea why this has been happening on this and 2 other sites that have panels that would have been produced around the same time period from Salem.

please let me know if you have any info.
Thanks.
