SAMLEX EVO Pure Sine Wave Inverter - 3000w - 19-3073 EVO-3012

Build a complete off-grid power solution with the Samlex EVO Pure Sine Wave Inverter/Charger (Part #EVO-3012 / 19-3073). This 3000W EVOLUTION Series unit isn't just an inverter — it intelligently integrates a pure sine wave inverter, a 130-amp 4-stage battery charger, and a 70-amp transfer relay into a single advanced, affordable all-in-one solution. Designed for boats, RVs, cabins, specialty vehicles, alternative energy systems, backup power, and emergency installations.

Three Products in One — Inverter + Charger + Transfer Relay

The EVO-3012 replaces three separate components with one integrated unit:

• 3000W pure sine wave inverter — clean, utility-grade AC power from 12V battery input
• 130A 4-stage battery charger — keeps your house batteries fully charged when shore power or generator power is available
• 70A transfer relay — automatically switches between shore/generator power and inverter power, so your AC loads run continuously without interruption

For off-grid setups, that integration is a real win — less wiring, less rack space, less complexity, and a single coordinated system rather than three separate boxes that don't quite know about each other.

True Pure Sine Wave — Same Quality as the Grid

The EVO produces true pure sine wave AC output, which is the same quality and waveform as utility power. That matters: cheaper modified sine wave inverters cause issues with sensitive electronics, motors, CPAP machines, microwaves, and modern appliances. With pure sine, everything runs the way it's designed to — quietly, cleanly, without buzzing or interference.

4-Stage Adaptive Battery Charging

The integrated 130-amp 4-stage charger delivers intelligent, adaptive battery management — properly charging your house batteries through every stage of the charging cycle for maximum capacity and longest possible battery life. Much more sophisticated than the basic single-stage chargers built into many converters.

Seamless Power Transfer

The built-in 70-amp transfer relay handles the automatic switching between shore/generator AC power and inverter AC power. When shore power is connected, the system passes that through (and charges your batteries simultaneously). When shore power drops, the relay automatically switches to inverter operation — your AC loads keep running without you doing anything.

Built for Tough, Off-Grid Applications

The Evolution Series is engineered specifically for the demanding conditions of off-grid power systems: boats, RVs, cabins, specialty vehicles, alternative energy systems, backup power, and emergency installations. It's reliable enough to be the heart of a serious off-grid setup, not just a casual accessory.

Inverter-Only Alternative

If you don't need the integrated charger and transfer relay (because your RV already has a separate converter/charger and you just need pure sine AC for sensitive loads), the Samlex PST-3000-12 inverter is the inverter-only option at the same 3000W rating.
