For whole-home connection, you will need a transfer switch or interlock kit (sold separately). DuroMax recommends hiring a licensed electrician for installation. Check the combined wattage of your essential appliances before purchasing to confirm compatibility.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eHow does the tri fuel system work - can I switch fuels while it's running?\u003c\/summary\u003e\n\u003cp class=\"faq-content\"\u003eThe XP28000iHT features a front-panel fuel selector switch with GAS, LPG, and NG positions. While it is best practice to switch fuels while the generator is off or at idle to avoid stalling, the selector makes transitioning between fuel types straightforward. The generator includes a propane hose and regulator as well as a 15-foot natural gas hose with quick connect fittings so you can hook up to either fuel source right out of the box.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eIs this generator safe to use with sensitive electronics like computers and TVs?\u003c\/summary\u003e\n\u003cp class=\"faq-content\"\u003eYes. As an inverter generator, the XP28000iHT produces a clean sine wave with total harmonic distortion (THD) of less than 3%. This is comparable to - or better than - the power from your home's utility grid, making it completely safe for laptops, desktop computers, televisions, medical equipment, and other sensitive devices.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat is the 2-Wire Start feature and how does it work?\u003c\/summary\u003e\n\u003cp class=\"faq-content\"\u003eThe 2-Wire Start allows the generator to connect directly to a solar inverter's dry contact terminals. When your battery bank drops below a set threshold, the solar inverter sends a signal through the dry contacts that automatically starts the XP28000iHT. Once the batteries are charged, the inverter signals the generator to shut off. This creates a seamless, automated backup charging system without any manual intervention.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eHow is this generator delivered, and does it require assembly?\u003c\/summary\u003e\n\u003cp class=\"faq-content\"\u003eThe XP28000iHT ships via freight with free liftgate and curbside delivery to the 48 contiguous U.S. states - it will be placed at your driveway or curb. At 466 lbs, you will need assistance moving it into position. Assembly is minimal: add the recommended oil (10W-30), connect your fuel source, and it is ready to start. The included Owner's Manual walks through the initial setup process step by step.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eDoes the CO alert actually shut the generator off automatically?\u003c\/summary\u003e\n\u003cp class=\"faq-content\"\u003eYes. The built-in CO sensor continuously monitors carbon monoxide levels in the generator's vicinity. If CO accumulates to a dangerous threshold, the generator automatically shuts itself off and alerts you - no manual intervention required. This is an important safety feature, though it does not replace the fundamental rule of always operating any generator outdoors and away from windows, doors, and vents.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003c\/div\u003e\n\u003chr\u003e\n\n\u003ciframe src=\"https:\/\/www.youtube.com\/embed\/VL7GoqneqeQ?rel=0\u0026amp;showinfo=0\u0026amp;vq=1200\" frameborder=\"0\" allowfullscreen loading=\"lazy\"\u003e\u003c\/iframe\u003e\n","brand":"DuroMax","offers":[{"title":"Default Title","offer_id":55608006770993,"sku":"XP28000IHT","price":9095.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1724\/7681\/files\/XP28000iHT_001_fab890cc-4647-4c3a-92d4-a416477abef5.png?v=1785965471","url":"https:\/\/omahasportsandgames.com\/products\/duromax-xp28000iht-28-000w-tri-fuel-portable-inverter-generator-with-co-alert","provider":"Omaha Sports \u0026 Games","version":"1.0","type":"link"}
