It is essential for safety and eliminates the need for galvanic isolators and polarity alarms.\u003c\/p\u003e\u003cp\u003eSafety is taken for granted in the case of a normal onshore installation. A circuit breaker or a GFCI (Ground-Fault Circuit Interrupter) will trip in the event of a short circuit or current leakage to ground. Connecting the ground wire of the shore-side supply to the metal parts of the boat will result in galvanic corrosion (see below). Bringing only the live and neutral wire on board results in an unsafe situation because GFCIs will not work, nor will a fuse blow in case of a short circuit to a metal part on the boat.\u003c\/p\u003e\u003cp\u003eGalvanic corrosion occurs when two dissimilar metals in electrical contact are simultaneously exposed to an electrically conducting fluid. Seawater and, to a lesser extent, fresh water are such fluids. In general, the more active alloy of the couple corrodes preferentially while the less active (more noble) material is cathodically protected. The rate of galvanic corrosion is a function of several variables including area ratios, conductivity of the fluid, temperature, nature of the materials, etc.\u003c\/p\u003e\u003cp\u003eIt is a misunderstanding that galvanic corrosion occurs only in metal and aluminium hulls. In fact it can occur on any boat as soon as a metallic part (the shaft and propeller) is in contact with water. Galvanic corrosion will quickly dissolve your sacrificial anodes, and attack the shaft, propeller and other metal parts in contact with water as soon as the boat is connected to the shore -side supply.\u003c\/p\u003e\u003cp\u003eIt might therefore be tempting not to connect the ground conductor: this is however e xtremely dangerous because GFCIs will not work nor will a fuse blow in case of a short circuit to a metal part on the boat.\u003c\/p\u003e\u003cp\u003eThe best solution to avoid galvanic corrosion and at the same time prevent any uns afe situation is to install an Isolation Transformer to connect to the shore-side supply.\u003c\/p\u003e\u003cp\u003eThe Isolation Transformer eliminates any electrical continuity between shore power and the boat. The shore power is fed to the primary side of the transformer and the ship is connected to the secondary.\u003c\/p\u003e\u003cp\u003eThe Isolation Transformer completely isolates the boat from the shore ground. By connecting all metal parts to the neutral output on the secondary side of the transformer, a GFCI will trip or a fuse will blow in case of a short circuit.\u003c\/p\u003e\u003cp\u003eSoft start is a standard feature of a Victron Energy isolation transformer. It will prevent the shore power fuse from blowing due to the inrush current of the transformer, which would otherwise occur.\u003c\/p\u003e\u003cp\u003eIt is also recommended, for optimal safety, to connect the secondary neutral of the transformer to ground when the boat is out of the water.\u003c\/p\u003e\u003cp\u003e4500 Watt Auto 115\/230 V - This model will automatically switch to 115 V or 230 V supply, depending on input voltage.\u003c\/p\u003e\u003cp\u003eSupply 88 V  130 V: switches to 115 V supply\u003c\/p\u003e\u003cp\u003eSupply 185  250 V: switches to 230 V supply range.\u003c\/p\u003e\u003cp\u003eNote: The AC input voltage is raised by 1:1.05 ratio at the AC output.\u003c\/p\u003e\u003cstrong\u003ePlease contact your dealer for any returns, repairs or support issues related to this product.\u003c\/strong\u003e \u003c!--- cis2:m2lumZRk ---\u003e\n\u003cp\u003eThe Victron Energy 4500W Auto Isolation Transformer is designed to ensure safety and protect your vessel or RV from galvanic corrosion when connected to shore power. This transformer eliminates electrical continuity between the shore power and your boat or RV, significantly reducing the risk of galvanic corrosion that can damage metal components such as shafts, propellers, and hull fittings. Its automatic switching feature allows it to adapt seamlessly between 115V and 230V supply voltages, making it versatile for various regional power standards. When supplied with voltage in the range of 88V to 130V, the transformer switches to 115V output, and for inputs between 185V and 250V, it switches to 230V output, ensuring consistent power delivery without manual adjustments. The transformer’s design incorporates a soft-start feature, preventing inrush current from blowing fuses or tripping circuit breakers during startup, thereby enhancing safety and reliability. The secondary neutral connection can be grounded when the vessel is out of water for additional safety, aligning with best practices for electrical safety on boats and RVs. Constructed by Victron Energy, this transformer combines high power capacity with safety features essential for marine and mobile applications, providing peace of mind during shore power connections. Its compact dimensions and lightweight design make installation straightforward without sacrificing durability or performance. This product is ideal for boat owners and RV travelers seeking to prevent galvanic corrosion, ensure electrical safety, and maintain optimal operation of onboard electrical systems. Proper use of this isolation transformer helps extend the lifespan of metal components and enhances overall safety when connected to shore power systems.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003ePower Capacity: 4500 Watts for demanding electrical applications\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eAutomatic Voltage Switching: seamlessly switches between 115V and 230V inputs\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eGalvanic Corrosion Prevention: eliminates electrical continuity between shore power and boat\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSoft Start Feature: prevents inrush current from tripping fuses or circuit breakers\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSafety Grounding: secondary neutral can be grounded when vessel is out of water\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCompact and Lightweight: easy to install and transport\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eHigh-Quality Construction: built by Victron Energy for durability and reliability\u003c\/li\u003e\u003c\/ul\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":44430803206186,"sku":"114094","price":597.55,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0692\/2285\/8794\/files\/114094XL.jpg?v=1780850328","url":"https:\/\/atticusgoods.com\/products\/victron-energy-4500w-auto-isolation-transformer-for-marine-and-rv-use-part-itr050452042","provider":"Atticus Goods","version":"1.0","type":"link"}
