Ct coil distance
I have got a 50m run from inverter location to the mains. the maximum length recommended if joining the ct clamp cable is 20m. What’s my options?

I think there is another factor - interference. If the ct clamp cable is laid next to the main power cable it will pick up noise from the power cable, especially when the inverter is send a lot of power and you are trying to achieve zero export. If there is a large load in the property consuming power from the remote inverter the high current will cause interference to the CT clamp cable which will have very little current around the zero export measurement - so the reading will be very susceptible to interference.
