hi new to this but seems like a good site to swap info and practices,
ok my problem or question is 50 kw solar pv on a farm (or anywhere) but it is ground mounted usually in a field some 50mtrs away. so the main incoming earth to the farm is tn-cs after any advice on how to earth the system, we have a feeder piller in the field with the various dbs ,isolaters and meters inside. inverters are outside ip rated of course what we have been doing is exporting the earth to the feeder piller to protect the armoured feeding the array however not terminating the earth at the feeder piller side so the cable is protected (also 300ma rcd at supply end and seperate isolater) then we are spiking the feeder piller and array and anything in the field with potential any help or thoughts would be welcome !!
