Court House Green – Coventry – Fronius IG TL ERROR state 447
System reported as intermittent fault.
After an initial inspection an insulation resistance fault was located on the array DC wiring.
A second visit would be required to remove panels and investigate further.
Severe damage was found to DC cables on roof which was repaired with the array reinstated.
Poor workmanship also contributed to the insulation resistance fault due to MC3 connectors
being left immersed in water where they had been installed into system rails which form a gutter for water.
The cable damage was due to squirrels.
System left in full working order.
