On a system built from Renogy parts, that turns several isolated gadgets into something that behaves like one system.\u003c\/p\u003e\u003ch3\u003eSizing: 300A is not always enough\u003c\/h3\u003e\u003cp\u003eCheck your worst case. A 3,000W inverter at 12V draws around 270A, which is inside the 300A continuous rating but leaves very little margin once you add a fridge and a heater. For a big inverter build, the 500A monitor is the safer choice; for a 2,000W system, 300A is ample.\u003c\/p\u003e\u003ch3\u003eBefore you order\u003c\/h3\u003e\u003cp\u003eFits with M10 bolts and surface mounts, so allow space beside the battery. Operating range is −10°C to 50°C — narrower than the batteries it monitors, so keep it inside the insulated envelope.\u003c\/p\u003e","brand":"Renogy","offers":[{"title":"Default Title","offer_id":51358104387751,"sku":"RSHST-B02P300-UK","price":71.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0770\/1158\/3143\/files\/01__28996.1709289149.1280.1280.jpg?v=1789801244","url":"https:\/\/shop.roamwired.com\/products\/renogy-battery-shunt-300","provider":"Roam Wired Shop","version":"1.0","type":"link"}
