Hello
I have a query raised by a client stating that a PV solar Generation site built on agricultural land is non compliant due to direct buried cables.
Some of the DC string cable is direct buried roughly at 600 depth laid within cable sand and protection tape over.
The cable spec is EU and states is suitable for direct burial.
The protection system constantly monitors the insulation resistance and dis engages the inverter upon fault.
The client has stated a non compliance due that no mechanical protection has been installed underground but all cables above ground are mechanically protected.
