Hi, I've just had an electrician round to wire my inverter to the consumer unit. I noticed when I got the invoice, nothing was added to the cu for dc protection, when I turned the inverter on the flow was going back to the grid when charging the batteries, I realised he had put the ct clamp the wrong way. He did not give me a certificate and is ignoring my messages, what options do I have?
