    Inverter on earth stake?

    Been asked to replace an old consumer unit, PV installed so bonding etc up to scratch. House supply is TNCS, however with the PV wiring the inverter (Fronius) is on its own earth stake! So that makes 2 earthing systems in close proximity! Why would they want to earth stake the inverter?

    Hi People, I am new to the forum and I am looking for price advice.

    We have a convenience store and are having a new suspended ceiling installed but we are also having 16 light fittings installed. I believe the wiring is okay and I think we will be going for LED fittings. I just wondered if anyone can advise on the price roughly just so I have an idea.
