Samlex 4000W Pure Sine Inverter/Charger - 24V

The Samlex Evolution™ EVO-4024 is a robust 4000W Pure Sine Wave Inverter/Charger tailored for marine and boating applications. Combining advanced inverter technology with an adaptive battery charger and a reliable transfer relay in a single unit, it provides steady and efficient AC power to your vessel’s electrical systems, ensuring seamless operation of essential onboard electronics.

Key Features

• Pure sine wave inverter delivering 4000W continuous and 12000W surge power.
• 24 VDC input and 120 VAC output for versatile marine power needs.
• Integrated 110 Amp 4-stage adaptive battery charger for optimal battery maintenance.
• 70 Amp transfer relay for automatic switching between power sources with minimal transfer time.
• Durable construction with 9-point physical protection monitoring designed for harsh marine environments.
• Supports solar integration for sustainable energy use on board.

AC Inputs

• Dual AC inputs for grid (priority #1) and generator (priority #2) connections, allowing simultaneous use without reconfiguration.
• Generator input engineered to tolerate waveform distortions, preventing unnecessary inverter switching during generator operation.
• Programmable voltage and frequency thresholds to automatically switch power sources based on user-defined settings.
• Generator start can be initiated via the “Status Relay” contact, programmable to activate upon grid power loss.

Solar Integration

• Direct connection to a solar charge controller through the Battery Charger external DC input.
• ONLINE Mode prioritizes battery/inverter power over grid, ideal for vessels relying primarily on solar power when available.

Adaptive Battery Charger

• 4-stage (3 or 4 stage with equalization) charging to ensure complete battery cycles.
• Adaptive charging algorithm adjusts bulk charging based on battery condition, enhancing battery lifespan.
• Programmable battery voltage thresholds to control charging initiation.

Transfer Switch System

• Zero transfer time when switching from inverter to grid, synchronizing with the waveform for seamless power transition.
• Less than 16ms transfer time when switching from grid to inverter during power loss.

Surge Capacity and Power Boost

• Handles up to 3X surge power for heavy load demands.
• Large power overload capabilities allow for long-term heavy load handling without the need for a larger inverter.

Advanced Protection and Technology

• Operates at 165 million instructions per second, delivering lightning-fast load and response times.
• Bullet-Proof Intelligence with 9 physical protection points, scanning up to 10,000 times per second to detect and prevent fault conditions.
• EVO-RC remote control (sold separately) allows for detailed performance monitoring and fault logging with data stored on a removable 16GB SD card.
• Five temperature sensors manage two-speed controlled cooling fans, reducing noise and energy consumption by operating fans only when necessary.
