    Mastervolt 24/2500-60 Mass Combi Inverter Charger 24V 2,500 Watt

    Every model of the Mastervolt Combi is highly versatile, so using one greatly simplifies installation. This single inverter and battery charger brings you fast and complete charging of your starter and service batteries, it also provides a silent, robust and clean AC power supply (pure sine wave).

    Multiple AC outputs allow heavy-draw items to be separated from the most critical equipment, making sure they don't unintentionally deplete your batteries. The AC inputs facilitate both mains and generator connections, which the Combi can support with additional power if your loads require more than either can provide.

    Essentially, just this one product can handle all the power requirements in an autonomous system.

    Modern technology

    The unique design of the Combi range is typically Mastervolt. Rather than installing heavy transformers, you can use our high-frequency technology for major benefits in terms of compact size, a lightweight chassis and silent running (there is no transformer hum).

    The Last Battery you’ll Ever Buy.

    Over a century ago, Thomas Edison found a battery design that he considered to be nearly perfect. Today, Iron Edison is proud to offer an updated version of this incredible design that is specifically manufactured for Renewable Energy systems.

    An Iron Edison Nickel-Iron Battery
    • Refillable alkaline electrolyte
    • Large storage capacity (up to 48 kWh)
    • Full depth of discharge
    • 12, 24 and 48 Volt applications
    • Nearly indestructible

    Iron Edison now offers a full line of solar panels, charge controllers, inverters and more!
