Xantrex PROsine 1000i 24V to 230V Sine Wave Inverter

The Xantrex PROsine 1000i is a compact, high-quality inverter that converts 24-volt DC battery power into 1000 watts of true sine wave AC at 230 volts and 50 hertz. It's the export-market configuration built for boats, vehicles, and off-grid installations wired to the 230-volt, 50-hertz standard used across much of the world. If your vessel runs a 24-volt house bank and you want dependable mains-style power at anchor, this is the kind of inverter that quietly earns its keep trip after trip.

What sets the PROsine line apart is the quality of its output. True sine wave AC is smooth and clean, matching the shape of the power you'd get from a shore connection. That matters more than people expect. Laptops, camera chargers, medical devices like CPAP machines, variable-speed tools, and modern appliances all run cooler and quieter on a true sine wave, and many sensitive loads simply won't tolerate a rougher waveform. With the PROsine 1000i you're not guessing whether a device will play nicely. It just works, the way it would at home.

The 1000i is rated for 1000 watts of continuous output with a surge capacity of 1500 watts, giving you the headroom to start loads that draw a brief spike of current when they switch on. Efficiency sits around 90 percent, so you're converting battery energy into usable AC without wasting it as heat. On a 24-volt system that efficiency also means lower DC current for a given load, which keeps your cabling and connections running cooler and helps preserve the battery bank over a long day off the grid.

This is a hardwired inverter, designed to be permanently installed as part of your onboard or off-grid electrical system rather than plugged in and moved around. That approach gives you a cleaner, safer, more professional installation, with the AC output wired into a distribution panel or dedicated circuits. It also means the inverter becomes a fixed, trusted part of the boat's electrical picture rather than one more loose box sliding around a locker in a seaway. The PROsine platform is also remote-capable, so you can add a panel or display to monitor status and control the inverter from a convenient location instead of crouching next to the unit itself. That kind of at-a-glance visibility is genuinely useful when you're trying to manage a battery bank carefully over several days away from shore power.

• 1000 watts continuous, 1500 watts surge output
• 24-volt DC input for 24-volt house banks
• 230-volt AC at 50 hertz true sine wave output
• Around 90 percent conversion efficiency
• Hardwired installation with remote-capable control

Consider how it fits a real boat. You're on a mooring for the evening, the main engine is off, and the 24-volt bank is carrying the load. The PROsine 1000i runs the galley small appliances, keeps the laptops and tablets charged, and powers the lights and chargers your crew depends on, all without a generator running. Because the output is true sine wave, the fridge compressor and the phone chargers behave exactly as they should. In the morning, when you charge the batteries back up from your engine or another source, you're ready to do it all again.

At roughly 18 pounds, the 1000i is light enough to mount on a bulkhead yet substantial enough to signal the serious engineering inside. Give it a cool, ventilated spot close to the battery bank to keep DC runs short, wire the AC output into your panel to code, and add the optional remote if you want at-a-glance monitoring. For anyone building or upgrading a 24-volt, 230-volt system who won't compromise on clean power, the Xantrex PROsine 1000i is a smart, reliable choice that you'll forget about in the best possible way, because it simply does its job.
