It is the component that makes managed self-consumption possible, and without a reliable measurement that management simply does not exist.\u003c\/p\u003e\n \u003cp\u003eIt works \u003cstrong\u003ethree-phase up to 100A\u003c\/strong\u003e with \u003cstrong\u003edirect connection\u003c\/strong\u003e: the conductors pass through the meter, no current transformers needed.

One thing worth knowing: on many systems the KEM is enough and there is no need to move up to the KSEM, which is more capable but also dearer. That saving is often missed because the KSEM goes in out of habit.\u003c\/p\u003e\n \u003ch3\u003eKey strengths\u003c\/h3\u003e\n \u003cdiv class=\"cs\"\u003e\n  \u003cdiv class=\"c\"\u003e \u003cb\u003eThree-phase 100A direct\u003c\/b\u003e\u003cspan\u003eConductors run through the meter: no CTs to add.\u003c\/span\u003e \u003c\/div\u003e\n  \u003cdiv class=\"c\"\u003e \u003cb\u003eRS485 Modbus RTU\u003c\/b\u003e\u003cspan\u003eSerial link to the inverter on an open, proven protocol.\u003c\/span\u003e \u003c\/div\u003e\n  \u003cdiv class=\"c\"\u003e \u003cb\u003e3 DIN modules\u003c\/b\u003e\u003cspan\u003e100\/72\/66mm: it fits a crowded enclosure.\u003c\/span\u003e \u003c\/div\u003e\n  \u003cdiv class=\"c\"\u003e \u003cb\u003eFor PLENTICORE inverters\u003c\/b\u003e\u003cspan\u003eplus, BI and G3 series: exact list in the Kostal document.\u003c\/span\u003e \u003c\/div\u003e\n  \u003cdiv class=\"c\"\u003e \u003cb\u003eOften the KEM is enough\u003c\/b\u003e\u003cspan\u003eWhere the application allows it, it saves the cost of a KSEM.\u003c\/span\u003e \u003c\/div\u003e\n \u003c\/div\u003e\n \u003ch3\u003eTechnical specifications\u003c\/h3\u003e\n \u003cdiv class=\"tw\"\u003e\u003ctable\u003e \u003cthead\u003e\u003ctr\u003e \u003cth\u003eFeature\u003c\/th\u003e \u003cth\u003eValue\u003c\/th\u003e \u003c\/tr\u003e\u003c\/thead\u003e \u003ctbody\u003e\n  \u003ctr\u003e \u003ctd\u003eProduct code\u003c\/td\u003e \u003ctd\u003eKOSTAL-ENERGY-P\u003c\/td\u003e \u003c\/tr\u003e\n  \u003ctr\u003e \u003ctd\u003eManufacturer\u003c\/td\u003e \u003ctd\u003eKostal\u003c\/td\u003e \u003c\/tr\u003e\n  \u003ctr\u003e \u003ctd\u003eModel\u003c\/td\u003e \u003ctd\u003eEnergy Meter P series (KEM-P)\u003c\/td\u003e \u003c\/tr\u003e\n  \u003ctr\u003e \u003ctd\u003eType\u003c\/td\u003e \u003ctd\u003eBidirectional DIN rail energy meter\u003c\/td\u003e \u003c\/tr\u003e\n  \u003ctr\u003e \u003ctd\u003ePhases\u003c\/td\u003e \u003ctd\u003ethree-phase\u003c\/td\u003e \u003c\/tr\u003e\n  \u003ctr\u003e \u003ctd\u003eMaximum current (Imax)\u003c\/td\u003e \u003ctd\u003e100A\u003c\/td\u003e \u003c\/tr\u003e\n  \u003ctr\u003e \u003ctd\u003eConnection type\u003c\/td\u003e \u003ctd\u003edirect, no current transformers\u003c\/td\u003e \u003c\/tr\u003e\n  \u003ctr\u003e \u003ctd\u003eCommunication\u003c\/td\u003e \u003ctd\u003eRS485\u003c\/td\u003e \u003c\/tr\u003e\n  \u003ctr\u003e \u003ctd\u003eProtocol\u003c\/td\u003e \u003ctd\u003eModbus RTU\u003c\/td\u003e \u003c\/tr\u003e\n  \u003ctr\u003e \u003ctd\u003eCompatibility\u003c\/td\u003e \u003ctd\u003eKostal PLENTICORE plus, PLENTICORE BI and PLENTICORE G3 inverters\u003c\/td\u003e \u003c\/tr\u003e\n  \u003ctr\u003e \u003ctd\u003eMounting\u003c\/td\u003e \u003ctd\u003eDIN rail, 3 modules wide\u003c\/td\u003e \u003c\/tr\u003e\n  \u003ctr\u003e \u003ctd\u003eDimensions (H\/W\/D)\u003c\/td\u003e \u003ctd\u003e100\/72\/66mm\u003c\/td\u003e \u003c\/tr\u003e\n  \u003ctr\u003e \u003ctd\u003eIngress protection\u003c\/td\u003e \u003ctd\u003eIP20\u003c\/td\u003e \u003c\/tr\u003e\n  \u003ctr\u003e \u003ctd\u003eWeight\u003c\/td\u003e \u003ctd\u003e0.32kg\u003c\/td\u003e \u003c\/tr\u003e\n \u003c\/tbody\u003e \u003c\/table\u003e\u003c\/div\u003e\n \u003ca class=\"d\" href=\"https:\/\/samonolithportalprodcdn.blob.core.windows.net\/assets\/general_product_documents\/d76180c3f9a1853f8cd8ccadf23b03cb1345657d_DB_KEM_P_en.pdf\" target=\"_blank\" rel=\"noopener\"\u003e\u003ci\u003ePDF\u003c\/i\u003e\u003cspan\u003eManufacturer datasheet\u003csmall\u003ePDF document\u003c\/small\u003e\u003c\/span\u003e\u003c\/a\u003e\n\u003c\/div\u003e","brand":"Kostal","offers":[{"title":"Default Title","offer_id":55354725826897,"sku":"KOSTAL-ENERGY-P","price":229.68,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2510\/0896\/files\/KOSTAL-ENERGY-P.jpg?v=1792288320","url":"https:\/\/litio.store\/en\/products\/contatore-di-energia-kostal-energy-meter-p-kem-p-trifase-100a-diretto-rs485-modbus-rtu","provider":"litio.store","version":"1.0","type":"link"}
