We have a standard 3.6kW solar setup installed in 2011, it has a Total Generation Meter fitted inside between the inverter and the CU. Outside in the meter cupboard there is an old two-rate meter for the E7 supply.
Neither of the above measures the amount exported (and it is not possible to infer it from their readings because of the unknown internal consumption of solar power).
So I want to add another meter to measure actual export (and ideally with an extra register for total import, which will enable me to check the DNO's meter. I do not want to change this for a smart meter.)
What should I buy and what is the recommended way of fitting it?
TIA, Chris
