I'm implementing an 8kW PV array, with grid-tie via an MLT Drives PowerStar 12kW grid-tied bi-directional inverter that manages syncing, islanding, etc. The only challenge we face is how to handle nett metering.
Anyone know, or know someone, where I can source a suitable meter that the local municipality can install? Ideally the meter should measure both energy imports and exports to the grid, with a nett metering reading that can be read by the utility meter reader.
My supply is single phase 60A currently metered by a Plessey pre-paid ECON model. It cannot handle energy exports and immediately goes into 'tamper' mode when energy is exported from the SSEG to the utility.
My municipality is loathe to use an old rotating-disc electro-mechanical meter as these are not very accurate, apparently.
Any pointers, contacts or shared experience most appreciated.
