Micro-generators continue to comply with IS EN 50549-1 but the internal protection settings have been revised to facilitate the connection of much greater volumes of Micro-Generation on the network.
Additionally, to provide clarity and simplicity, the export rating of 6kVA single phase or 11kVA three phase, is now assessed based on the size of the Inverter through which the PV panels transport their generation. This is because the Inverter will limit any output to 6kVA/11kVA, even if there is an over-install of generation (above 6/11kVA) behind the inverter, for the purposes of increasing kWh production at times of lower light levels.
However, the peak export from their Inverter must not exceed 6kVA single phase or 11kVA three phase.
Note: Only registered Micro-generators are eligible for any export payments.
