Product Description


    Sterling ProCombi S Pure Sine Wave Inverter-Chargers are straightforward, powerful and robust. Combining an inverter, battery charger and 30A transfer switch, they are compact, simple, and easy to install. They are also very energy efficient, and easy on the pocket. It's hard to find a quality inverter/charger for less. We have sold quite a few of these over the last three years, with good feedback from customers and professional installers.

    The battery charger features advanced multi-stage charging with digital control. Adjustment is easily made via a selector switch to accommodate alternative battery types.The control and indicator panel can be remote mounted via a 30' cable that is included with the unit.

    Compared to the Magnum MS2812, the Sterling is narrower, longer, a few pounds lighter, and with a smaller but still resepectable 55-amp charger. At just over half the price, the Sterling includes a remote with on/off capability, and allows you to choose among battery types at the charger. The Magnum requires a nearly $200 remote to choose anything but a flooded lead-acid battery. The Sterling has a two-year warranty, the Magum has three years.
