Samlex 4000W Pure Sine Inverter/Charger - 24V

The Samlex 4000W Pure Sine Inverter/Charger – 24V (model EVO-4024) is a three-in-one power solution engineered for serious mobile applications, overlanding rigs, RVs, marine vessels, and off-grid automotive builds. This Evolution Series unit combines a pure sine wave inverter, adaptive battery charger, and automatic transfer relay into a single compact chassis, eliminating the need for separate components and reducing installation complexity. Whether you're powering workshop equipment during extended vehicle repairs, running sensitive electronics in a remote job site, or maintaining auxiliary batteries during prolonged downtime, this inverter/charger delivers the stable, clean AC power that modern automotive systems demand.

At 4000W continuous output, the Samlex EVO-4024 generates true sine wave AC—not modified or quasi-sine—making it safe for sensitive automotive diagnostic tools, laptop chargers, compressors, and climate control equipment that stock inverters damage or destabilize. The integrated adaptive charger intelligently manages 24V battery recharge cycles, extending cell lifespan and preventing overcharge scenarios common in marine and RV applications. The integrated transfer relay automatically switches between shore/generator AC power and battery-backed inverter output, ensuring uninterrupted power during shore power loss or power-source transitions. Weighing 73.5 lbs and measuring 16 × 15 × 22 inches, this unit mounts efficiently in engine bays, under-seat storage, or auxiliary power compartments without consuming excessive space—critical for fabricators who balance power delivery with functional vehicle layout.

Mechanics, fabricators, and expedition builders benefit most from this inverter/charger when retrofitting auxiliary power into trucks, vans, and off-road platforms with 24V electrical systems. Installation requires hardwired DC input from a dedicated 24V battery bank (deep-cycle or lithium), sized appropriately to sustain 4000W loads—typically a dual or quad-cell LiFePO₄ system or multi-battery series configuration. The unit's compact form factor pairs seamlessly with existing fuse blocks, disconnect switches, and cable runs, and its pure sine output ensures compatibility with modern engine computers, fuel-injection diagnostics, and high-frequency welding equipment. Marine users, RV owners, and remote-site contractors who demand reliable, professional-grade power conversion choose the Samlex Evolution series for proven longevity and minimal voltage regulation noise.
