Samlex 12V 3000W Pure Sine Wave Power Inverter

The Samlex PST-3000-12 is a high-output inverter for installations that need substantial household-style AC power away from shore or utility service. It is designed for boats, mobile work vehicles, RVs, field sites, communications equipment, and emergency backup systems where sensitive electronics still need a clean waveform. Low RF emissions help it coexist with nearby electronic equipment, while the commercial-duty construction supports extended operation. The unit is also built to cope with demanding startup loads rather than serving only light electronics.

The protection system monitors low battery voltage, overvoltage, overtemperature, overload, and short-circuit conditions so a single fault is less likely to damage connected equipment. Temperature-controlled cooling manages heat without running the fan harder than necessary, and the inverter is specified for operation across a broad ambient-temperature range. Its surge capability reaches roughly twice the continuous output, giving motors and other startup-heavy loads additional headroom. Low idle consumption helps conserve battery capacity during periods when connected AC demand is light.

Two front-panel GFCI outlets provide convenient plug-in power, while hard-wire capability supports a more permanent AC installation. A dedicated remote input can be tied to ignition or another remote switch, and the optional RC-300 LCD remote provides another way to operate the inverter from a convenient location. The unit measures about 10.35 x 17.97 x 5.71 in and weighs approximately 21.6 lb, so the mounting surface should be strong and well ventilated. Samlex currently lists a three-year limited warranty for this model.

• High-output design for demanding mobile and marine AC loads
• Dual GFCI receptacles plus fixed-wiring capability
• Low RF emissions for installations near sensitive electronics
• Remote-input support for external switching

Plan the installation around short, properly sized DC conductors because a high-output inverter can draw substantial current from the battery bank. Provide suitable fusing, grounding, ventilation, and AC branch protection according to the vessel or vehicle electrical design. For other sizes and system options, browse more Power Inverters.
