Xantrex PROsine 1800/24/120 Hard Wired Inverter — Product description

Transform your off-grid power setup with the reliable performance of a pure sine wave inverter designed for demanding applications. Whether you're powering sensitive electronics on a boat, running tools at a remote job site, or ensuring seamless operation in an RV system, this inverter stands out for its clean, utility-grade AC output and robust build.

Why Pure Sine Wave Matters for Your Electronics

Unlike modified sine wave alternatives that can cause humming, overheating, or premature wear on devices, this inverter produces a smooth, crystal-controlled true sine wave with less than 3% total harmonic distortion. This mirrors the power from your home grid, making it perfect for audio equipment, LED lights, medical devices, and variable-speed motors that demand precision. Users report flawless performance with everything from coffee makers to CPAP machines, extending equipment life and reducing noise complaints.

Impressive Power Delivery and Efficiency

Delivering 1800 watts continuous power with a 2900-watt surge capacity, it handles startup demands from high-draw appliances like refrigerators or power tools without skipping a beat. The innovative Powersave mode minimizes idle draw to just 1.5 watts, preserving precious battery life during low-demand periods—ideal for solar setups or extended outings where every amp-hour counts.

  • High-frequency switching: Keeps the unit lightweight and compact compared to bulkier transformers.
  • Removable LCD display: Mount it remotely for easy monitoring of input/output voltage, current, and fault status from anywhere in your setup.
  • 180-degree DC terminals: Simplifies wiring in confined spaces like engine compartments or battery bays.

Built-In Safeguards for Peace of Mind

Safety is engineered in from the ground up. Automatic overload shutdown prevents damage during spikes, while over/under voltage protection shields your batteries from deep discharge or spikes. Short circuit defense and AC backfeed prevention add layers of reliability, and thermal management ensures cool operation even under prolonged loads.

Flexible Hardwired Installation for Permanent Setups

Tailored for professional installs, the hardwire terminal strip integrates seamlessly into fixed electrical panels. Pair it with an optional transfer switch for automatic generator backup, creating a hybrid system that switches effortlessly. Available in 24-volt configuration, it's optimized for deep-cycle batteries common in marine, RV, and off-grid solar arrays.

Real-World Applications and User Benefits

Recreational enthusiasts love how it powers full home theater systems without interference, while industrial users appreciate its ability to drive pumps and compressors reliably. In marine environments, it resists corrosion and vibration; for RVers, the compact footprint frees up cabinet space. Maintenance is straightforward—regular ventilation checks and terminal inspections keep it running for years, backed by a solid two-year warranty.

Frequently Asked Questions

What makes this inverter suitable for sensitive electronics?

Its true sine wave output with under 3% THD provides clean power identical to grid electricity, preventing issues like buzzing fans or erratic digital clocks common with modified sine wave units.

How does the Powersave mode help extend battery life?

It reduces no-load consumption to only 1.5 watts by pulsing the output, significantly lowering standby drain—great for solar or long-term off-grid use.

Can the display be mounted away from the inverter?

Yes, the removable LCD panel supports remote mounting via an optional interface kit, allowing convenient monitoring without accessing the main unit.

What protections does it offer against overloads?

Features include automatic overload shutdown, over-temperature cutoff, over/under voltage guards, short circuit protection, and AC backfeed prevention for comprehensive safety.

Is this inverter compact for tight installations?

Absolutely—high-frequency technology makes it lighter and smaller than traditional inverters of similar rating, with 180-degree DC terminals easing access in cramped areas.

What surge power does it provide?

Up to 2900 watts, enabling it to start heavy loads like air conditioners or large motors that exceed the 1800-watt continuous rating momentarily.

Does it work with 24V battery banks?

Yes, this 24V model pairs perfectly with deep-cycle lead-acid, AGM, or lithium banks in solar, RV, or marine systems.

Power Inverters
PROsine 1800

PROsine™ Inverters deliver true sine wave output that is identical to AC power supplied by your utility. This clean output makes PROsine™ Inverters ideal for handling sensitive loads, while also improving AC equipment performance. Designed for recreational and industrial applications, expect the best performances from televisions, audio systems, speed tools, and any other electronics where you want nothing but the most optimal performance.

Product Description

Short circuit and AC backfeed protection

Options:
Available in 24 volt model
Models available with GFCI AC outlet or AC hardwire terminal strip for permanent installation into an electrical system (optional 15 A transfer switch available with hardwire option)
Remote interface kit for remote mounting of display module
Ultra-clean true sine wave power

With less than 3% total harmonic distortion, Prosine 1800 inverters deliver true sine wave output that is identical to AC power supplied by your utility. This clean output makes Prosine inverters ideal for handling sensitive loads and improves AC equipment performance. Expect trouble-free true sine wave electricity for televisions, audio systems, variable speed tools, and more.

Light and Compact

PROsine power inverters are lighter and more compact than other power inverters with similar power ratings because they use high-frequency switching technology in the power conversion process.

WARNING: This product can expose you to chemicals including Diisononyl Phthalate (DINP) which is known to the State of California to cause cancer, and Di-isodecyl Phthalate (DIDP) which is known to the State of California to cause reproductive harm. For more information go to P65Warnings.ca.gov.



The PRO sine wave inverter can provide the same true sine wave output as the AC power supplied by your utility company. The clean output makes PRO sine inverters ideal for handling sensitive currents.
