It connects via a 10-metre wire-end cable, giving installers room to position the metering point away from the inverter itself.\u003c\/p\u003e\u003ch2\u003eKey features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRatio\u003c\/strong\u003e, 400A:50mA for current sensing across the load range.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCable length\u003c\/strong\u003e, 10 metres, wire-end termination.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e, 0.25 kg.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatibility\u003c\/strong\u003e, designed for use with the Victron MultiPlus-II inverter\/charger range.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDesign\u003c\/strong\u003e, clips around an existing conductor without breaking the circuit.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhy it matters for ESS installations\u003c\/h2\u003e\u003cp\u003eThe MultiPlus-II uses this signal to monitor grid import and export in real time, which is what allows correct power assist, grid feed-in control and ESS charge\/discharge management. Without accurate current data at the CT input, the inverter cannot manage these functions properly.\u003c\/p\u003e\u003ch3\u003eCable length in practice\u003c\/h3\u003e\u003cp\u003eA 10-metre run means the metering point can sit some distance from the inverter or GX device without a field-spliced extension, which can introduce errors into the signal. The wire-end format connects straight to the designated terminal on the MultiPlus-II.\u003c\/p\u003e\u003ch2\u003eInstallation notes\u003c\/h2\u003e\u003cp\u003eFit this by a qualified electrician familiar with MultiPlus-II and ESS setup. The CT clips around the correct conductor, usually the grid live feed, and must be oriented as specified in the MultiPlus-II manual; the wrong orientation reverses the current reading. Do not install around bundled or multi-core cable containing more than one current-carrying conductor. UK grid-connected ESS installations must meet G98 or G99 requirements as applicable.\u003c\/p\u003e\u003ch2\u003eWhat's in the box\u003c\/h2\u003e\u003cul\u003e\u003cli\u003e1 x Current Transformer 400A:50mA with 10-metre wire-end cable\u003c\/li\u003e\u003c\/ul\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":52095611404576,"sku":"CTR140050100","price":33.59,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1010\/8148\/1504\/files\/ledandsolar-ctr140050100-1.webp?v=1785755956","url":"https:\/\/www.ledandsolar.co.uk\/products\/victron-current-transformer-400a-multiplus","provider":"LED \u0026 Solar","version":"1.0","type":"link"}
