{"product_id":"morningstar-mrc-1","title":"Morningstar Meterbus (RJ11) to EIA-485 Adapter Accessory","description":"The Morningstar MRC-1 is a Meterbus (RJ11) to EIA-485 adapter that lets Morningstar controllers and inverters fitted with a Meterbus port, but no EIA-485 port, join an EIA-485 communications network. It converts the Meterbus electrical interface to a standard four-wire EIA-485 bus, enabling networking with EIA-485 devices such as the GenStar MPPT and TriStar MPPT controllers. The adapter also supports EIA-485 communications with third-party hardware that uses Modbus, giving system integrators a straightforward way to bring Meterbus-only devices into a wider monitoring or control network.\n\n\u003ch2\u003eProduct Features:\u003c\/h2\u003e\n\n\u003cul class=\"custom-list-tick\"\u003e\n    \u003cli\u003eConverts the Morningstar Meterbus RJ-11 electrical interface to a standard EIA-485 interface.\u003c\/li\u003e\n    \u003cli\u003eSupports a four-wire EIA-485 bus carrying GND, Data A, Data B and Power.\u003c\/li\u003e\n    \u003cli\u003eSupplies isolated power to the EIA-485 network, removing the need for a separate bus power source in many installations.\u003c\/li\u003e\n    \u003cli\u003eIncludes reverse polarity protection at its EIA-485 power terminals.\u003c\/li\u003e\n    \u003cli\u003eBacked by a five year limited warranty.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eApplication Areas:\u003c\/h2\u003e\n\n\u003cul class=\"custom-list-tick\"\u003e\n    \u003cli\u003eNetworking Morningstar controllers or inverters that only have a Meterbus port, such as ProStar MPPT and PWM controllers, SunSaver MPPT, SunSaver Duo and SureSine Classic, onto an EIA-485 bus.\u003c\/li\u003e\n    \u003cli\u003eConnecting Meterbus-equipped Morningstar devices to EIA-485 products like the GenStar MPPT and TriStar MPPT controllers.\u003c\/li\u003e\n    \u003cli\u003eLinking Morningstar Meterbus devices to third-party EIA-485 equipment that communicates over Modbus.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSelection \u0026amp; Installation Notes:\u003c\/h2\u003e\n\n\u003cul class=\"custom-list-tick\"\u003e\n    \u003cli\u003eConfirm the Morningstar device has a Meterbus port rather than a built-in EIA-485 port before fitting the MRC-1.\u003c\/li\u003e\n    \u003cli\u003eThe MRC-1 is compatible with ProStar MPPT and PWM controllers, SunSaver MPPT, SunSaver Duo and SureSine Classic inverters; check your model against this list.\u003c\/li\u003e\n    \u003cli\u003eBecause the adapter can supply isolated power to the EIA-485 network, a separate bus power source may not be required in many setups.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eIn the Box:\u003c\/h2\u003e\n\n\u003cul class=\"custom-list-tick\"\u003e\n    \u003cli\u003e1 x Morningstar MRC-1 Meterbus to EIA-485 Adapter\u003c\/li\u003e\n    \u003cli\u003e1 x RJ-11 cable\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Morningstar","offers":[{"title":"Default Title","offer_id":53350428934442,"sku":"168090767","price":228.14,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0945\/0487\/8378\/files\/MRC-1_angled-transparent-background-300x209.png?v=1793169054","url":"https:\/\/store.techwave.com.au\/products\/morningstar-mrc-1","provider":"Techwave Store","version":"1.0","type":"link"}
