This signal is fed to the MultiPlus-II's CT input, enabling the inverter to monitor grid import and export in real time. Accurate current measurement is essential for correct power assist, grid feed-in control and ESS (Energy Storage System) operation.\u003c\/p\u003e\n\n\u003cp\u003eThe 10-metre cable length is a practical advantage in installations where the metering point is some distance from the inverter or GX device. This avoids the need for field-spliced extensions, which can introduce signal errors. The wire-end format means the installer connects directly to the designated terminal on the MultiPlus-II without requiring an intermediate connector.\u003c\/p\u003e\n\n\u003cp\u003eThis CT is a required accessory for MultiPlus-II installations where grid current monitoring is needed, particularly in ESS configurations where the system must track net grid power to manage charge and discharge behaviour correctly.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSKU: CTR140050100\u003c\/li\u003e\n  \u003cli\u003ePrimary current rating: 400A\u003c\/li\u003e\n  \u003cli\u003eSecondary output: 50mA\u003c\/li\u003e\n  \u003cli\u003eCable length: 10 metres\u003c\/li\u003e\n  \u003cli\u003eTermination: Wire-end\u003c\/li\u003e\n  \u003cli\u003eWeight: 0.25 kg\u003c\/li\u003e\n  \u003cli\u003eGTIN: 8719076065746\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eGrid current monitoring in Victron MultiPlus-II ESS installations.\u003c\/li\u003e\n  \u003cli\u003ePower assist configurations where grid import must be measured and limited.\u003c\/li\u003e\n  \u003cli\u003eResidential and light commercial solar-plus-storage systems using the MultiPlus-II.\u003c\/li\u003e\n  \u003cli\u003eInstallations where the metering point is up to 10 metres from the inverter location.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eWhat Is Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 x Current Transformer 400A:50mA with 10-metre wire-end cable\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eInstallation Notes\u003c\/h3\u003e\n\u003cp\u003eThis current transformer must be installed by a qualified electrician familiar with Victron MultiPlus-II systems and ESS configuration. The CT must be clipped around the correct conductor (typically the grid live feed) and oriented in the correct direction as specified in the MultiPlus-II installation manual. Incorrect orientation will result in reversed current readings and improper system behaviour. For grid-connected ESS installations in the UK, the system must comply with G98 or G99 requirements as applicable. Do not install around bundled or multi-core cables containing more than one current-carrying conductor.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":60190994268494,"sku":"CTR140050100","price":31.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0796\/3698\/8238\/files\/VoltaconSolar_-_CTR140050100_-_Current_Transformer_400A-50mA_for_MultiPlus-II_10m_Wire-end.webp?v=1784715731","url":"https:\/\/voltaconsolar.com\/products\/victron-current-transformer-400a-50ma-multiplus-ii-10m","provider":"VoltaconSolar","version":"1.0","type":"link"}
