EVOLUTION Series Inverter/Charger Pure sine wave inverter, battery charger and transfer switch – all in ONE device. Power the comforts of home while dry camping with the EVO inverter/charger RV power system. Run lights, a TV, microwave, hair dryer, computer and more without ever having to reconfigure your equipment when AC power is available! The EVO inverter/charger has separate inputs for shore power, a generator, a solar charging system – all three can be used to charge a bank of batteries. The EVO will automatically switch between different power sources as they become available and will convert the battery power to run 120 Volt devices when boon docking. Using state-of-the-art technology, the Samlex EVO inverter/charger operates at 165 million instructions per second with lightening fast load & response times and has 9 points of physical protection monitoring being scanned up to 10,000 times per second – it doesn’t get much smarter than this. The EVO-3012 is a 3000 Watt Pure Sine inverter, 12 VDC input, 120 VAC output, 50/60 Hz. It intelligently integrates a 130 Amp 4 stage Battery Charger and a 70 Amp Transfer Relay into an advanced and affordable RV power solution. (EVO-RC remote control sold separately.)

  • AC Inputs

    • - Two separate AC inputs – one for grid (priority #1), one for generator (priority #2), connect simultaneously, no need to reconfigure when different power sources are available.
    • - Generator Input is specifically designed to have more tolerance for wave form distortion, prevents unnecessary “rejection of AC input and switch to inverter” by tolerating distorted wave forms that can be produced by gritty generators
    • - Each AC input is programmable for voltage and frequency. User determines what the min and max thresholds are to switch from Grid or Generator to Inverter.
    • - Generator start can be initiated by “Status Relay” contact, can be programmed to activate when grid is lost.

    Solar Input

    • - Connect a solar charge controller directly to the EVO though the Battery Charger external DC Input, seamlessly integrates solar charging into the EVO’s power system.
    • - ONLINE Mode can be used to prioritize Batteries/Inverter over the grid, ideal for those wishing to operate primarily on solar power (when the grid is available, but might be costly).

    Battery Charger

    • - 3 or 4 stage charging with Equalization (must be manually initiated). 
    • - Adaptive algorithm is used during Bulk to assess the condition of the battery. Subsequent stages are then based on the condition of the battery rather than pre-set time periods for Absorption and Float. Prevents unnecessary charging, extends the life of batteries.
    • - Programmable – set battery voltage thresholds to initiate charging.

    Transfer Switch

    • - Zero transfer time when switching from Inverter to Grid. When grid comes on, the inverter synchronizes with the wave form and then transfers instantly at zero crossing.
    • - <16ms transfer when going from Grid to Inverter. When grid is lost, the transfer relay switches to inverter at the correct place in the wave form, the transfer takes less than 16ms.

    Surge Capacity (Power Boost)

    • - The EVO has 3X surge power
    • - Additionally, the EVO has large power overload allowances available for long periods of time. Increased inverter capacity means you can size your inverter smaller to handle heavy surge loads, reducing costs.

    State-of-the-Art Technology

    • - The EVO operates at 165 million instructions per second producing lightning fast load and response times
    • - The EVO is practically indestructible. It has “Bullet-Proof Intelligence” in the form of 9 physical points of protection monitoring being scanned up to 10,000 times per second for adverse conditions. The EVO will detect fault conditions and initiate a healthy shutdown before any product damage can be done.
    • - The EVO-RC remote control (sold separately) can be used to capture detailed EVO performance data. Records all detected faults and the conditions leading up to them. Data is stored on a removable 16GB SD Card (in the remote). Use data to analyze trends for more efficient use of system resources
    • - The EVO uses five temperature sensors placed throughout the unit to determine operation of 2 speed controlled cooling fans. Reduces unnecessary fan noise and energy consumption by only running when and where the fans are needed.


    • - Boats, RVs, trucks, specialty vehicles
    • - Alternative energy, off-grid, cabins, remote locations, areas with unreliable utility power
    • - Back-up and emergency power applications
