Samlex Evolution™ F Series 1200W, 120V Pure Sine Wave Inverter/Charger w/12V Input & 40 Amp Charger

The Samlex Evolution™ F Series 1200W, 120V Pure Sine Wave Inverter/Charger with 12V Input and 40 Amp Charger is purpose-built for serious vehicle builders, overlanders, and mobile technicians who demand clean, stable power in remote or off-grid installations. Whether you're running a fully equipped service bay in your expedition rig, powering diagnostic equipment during field repairs, or maintaining auxiliary systems in a custom build, this dual-function unit eliminates the need for separate inverter and battery charger hardware. The Evolution F Series addresses a critical pain point in mobile automotive work: reliable AC power and intelligent battery management from a single, compact platform.

This inverter/charger delivers genuine pure sine wave output—essential for sensitive diagnostic computers, laptop-based tuning software, and precision shop equipment that can fail or produce errors on modified square-wave or modified sine-wave power. The integrated 40-amp charger automatically and intelligently manages 12V battery bank charging, featuring multi-stage charging profiles that prevent overcharging and extend battery lifespan in applications ranging from lithium iron phosphate (LiFePO4) to traditional AGM or flooded lead-acid batteries. The 1200-watt continuous output supplies 120V AC power for inverter mode, while the charger function restores your battery banks efficiently from standard 120V household or generator AC sources. Heavy-duty internal switching and thermal management ensure reliable operation in demanding environments—tight engine bays, trailer batteries, and mobile command centers.

Mechanics and fabricators integrating dual-battery systems, auxiliary power distribution, or auxiliary power modules (APUs) will find the Evolution F Series indispensable for charging secondary battery banks without running the engine. Its compact 18 x 12 x 21-inch footprint fits beneath seats, in toolboxes, or in engine bay mounts on larger vehicles. The unit accepts 12-volt direct input from your primary battery bank, making it ideal for expedition vehicles, mobile service trucks, and project cars where independent AC power keeps workshop equipment operational regardless of grid proximity. Installers should plan for adequate cooling airflow and use appropriately rated fuses and heavy-gauge battery cables to handle the charger's full 40-amp input rating and the inverter's peak load demands.
