It suits marine, vehicle and off-grid setups where independent battery banks need to stay isolated from each other.\u003c\/p\u003e\u003ch2\u003eKey features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBattery outputs\u003c\/strong\u003e, supports up to three independent battery banks from one charging source.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent rating\u003c\/strong\u003e, 180A maximum continuous current, suited to high-output alternators and multi-bank systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiode isolation\u003c\/strong\u003e, blocks reverse current flow between battery banks so a depleted bank cannot draw down a healthy one.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3AC design\u003c\/strong\u003e, three outputs with AC-compatible input, so it works with AC chargers as well as DC alternators.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuild\u003c\/strong\u003e, aluminium construction with an integrated heat sink for passive cooling, weighing 1.4 kg.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eHow it works\u003c\/h2\u003e\u003cp\u003eDiode isolators let current flow in one direction only. While the charging source is active, current passes through the diodes to each connected battery bank. Once the source switches off, the diodes block any path between banks, so a flat bank cannot pull down a charged one.\u003c\/p\u003e\u003cp\u003eDiodes introduce a voltage drop, typically 0.5V to 0.7V, so the voltage reaching the batteries will be slightly lower than the source output. Where this matters, set the alternator or charger output voltage to compensate during commissioning.\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eMarine vessels with separate starter, domestic and bow thruster battery banks.\u003c\/li\u003e\n\u003cli\u003eMotorhomes and coaches with engine start, habitation and auxiliary battery banks.\u003c\/li\u003e\n\u003cli\u003eOff-grid vehicles and expedition builds needing isolated battery management.\u003c\/li\u003e\n\u003cli\u003eCommercial vehicles with multiple electrical systems requiring independent protection.\u003c\/li\u003e\n\u003cli\u003eSplit-charge systems fed by a high-output alternator or shore power charger.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhat's in the box\u003c\/h2\u003e\u003cul\u003e\u003cli\u003e1 x Victron Argodiode 180-3AC battery isolator unit\u003c\/li\u003e\u003c\/ul\u003e\u003ch2\u003eInstallation notes\u003c\/h2\u003e\u003cp\u003eFit by a qualified electrician or competent marine\/vehicle electrical engineer, in a well-ventilated spot so the heat sink can do its job. Cabling must be rated for the full 180A continuous load, with appropriate fusing on each battery connection. Allow for the diode voltage drop when setting the charging source output. Not intended for grid-connected solar PV systems and does not require G98 or G99 compliance.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":52095399362848,"sku":"ARG180301020","price":84.14,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1010\/8148\/1504\/files\/ledandsolar-arg180301020-1.webp?v=1785748968","url":"https:\/\/www.ledandsolar.co.uk\/products\/argodiode-180-3ac-battery-isolator","provider":"LED \u0026 Solar","version":"1.0","type":"link"}
