The MultiPlus-II reads this 50mA signal in real time to track AC input or output current, which supports grid interaction control and energy monitoring through the GX ecosystem. This is required for functions such as grid current limiting and ESS control, where the inverter needs to know the actual current at the grid connection point.\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eGrid current monitoring in MultiPlus-II ESS installations.\u003c\/li\u003e\n\u003cli\u003eAC input current limiting to prevent grid overload in residential battery storage systems.\u003c\/li\u003e\n\u003cli\u003eSingle-phase energy monitoring in off-grid and hybrid solar installations using Victron GX devices.\u003c\/li\u003e\n\u003cli\u003eRetrofit current measurement on existing MultiPlus-II installs needing grid sensing.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation notes\u003c\/h2\u003e\u003cp\u003eFitting must be carried out by a qualified electrician, since it involves working near live mains conductors within a consumer unit or distribution board. The MultiPlus-II must be configured to recognise the CT input before commissioning. UK grid-connected systems must meet G98 or G99 requirements as applicable, and the 100A rated primary current must not be exceeded.\u003c\/p\u003e\u003ch2\u003eWhat's in the box\u003c\/h2\u003e\u003cul\u003e\u003cli\u003e1x Current Transformer 100A:50mA with 1m cable (CTR110000500)\u003c\/li\u003e\u003c\/ul\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":52060531294496,"sku":"CTR110000500","price":20.44,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1010\/8148\/1504\/files\/ledandsolar-ctr110000500-1.webp?v=1785493170","url":"https:\/\/www.ledandsolar.co.uk\/products\/victron-current-transformer-100a-50ma-1m-multiplus-ii","provider":"LED \u0026 Solar","version":"1.0","type":"link"}
