[QUOTE="sepiot, post: 540873, member: 34959"] Thanks both for the mounting links. I wish I'd have ask here months ago, as I spent an age trying to find something appropriate and in stock. I have bought something already, but will keep your suggestions in mind in case it does not work well. Inverter manual only says 'Connect to a permanent grounded wiring system, and comply with local regulations'. I don't know if there could be a risk of (significant) leakage from the roof earth wire to the wire going to the CU, if both were connected to the same rod and there was some static build up in the roof. For the moment I'll connect both to the same rod, and test for voltage with a multimeter every now and then. There is bonding between the earth and N terminals on the inverter's AC output. Not sure if you are referring to that bonding? (ok, re-reading, i think you are talking about Ucatchmydrift system). [/QUOTE]
