Have you looked at cell fractures, l just replaced a module running on
enphase and it had fractures in the cell VOC was fine but under load there

Afternoon wrenches,
I have a friend who I helped install second hand modules onto a pergola
structure at their home.
The system is as follows:
44 - Siemens SP-150
1 - SMA SB6000US-12 (XFMR unit)
Since install, they have not produced half of what they should be. I have
tested the diodes and t
10 matches
