    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?

    4.57Kw PV with a 4Kw inverter. Inverter too small?

    Hi, I bought a 4.57Kw PV system (14x SunPower 327W panels) for my house last year. I now noticed that the installer fitted a SE4000 Solaredge which is limited to 4Kw. I can see from my stats that the system goes up to 3.98Kw but never above. It just goes flat and stays at 3.98Kw (especially...
