The Samlex Evolution Inverter/Charger Series, or EVO for short, and its features are covered in this brief product overview video by the altE Store. It's an all-in-one solution: Pure Sine Wave Inverter, a multistage battery charger, and a transfer switch. It can keep your batteries charged up and ready to go in the event of a power outage. If the grid goes out, you can automatically power your critical loads with the Samlex EVO from the battery bank. You can even charge up the batteries from solar panels and a charge controller connected to the EVO. The EVO will manage charging your batteries between the solar panels, generator, and grid.
