Outback, OBX-GIC2524P battery inverter

Pure sine wave power output Water-resistant sealed chassis Flexible mounting design Intelligent battery charging Integrated AC transfer relay Outback Extreme Series Inverter/Charger is all that its name implies.
Built from exceptionally rugged components not available in regular commercial “off-the-shelf" inverter/chargers, the water-resistant Extreme Series Inverters are designed to survive harsh environmental conditions including shock and vibration.
The Extreme Series Inverter/Charger features intelligent battery charging and an integrated AC transfer relay with automatic neutral-ground switching for mobile applications.
A “mount anywhere” design and silent operation, along with low-distortion pure sine wave power output, make them ideal for mobile electrical needs, and their ample surge capability can start multiple heavy loads simultaneously.
Integrated building block architecture allows expanding a system from 2 to 36 kW, and user-defined settings allow systems operation at 120 VAC, 120/240 VAC or 120Y208 VAC three-phase by stacking multiple Extreme inverter/chargers together.
