The Sunny Island is a bi-directional battery inverter and charger that can be used completely off-grid, or for battery backup in grid-tie systems with Sunny Boy grid-tie inverters. The Sunny Island is a complete power center with 6kW of sine wave output power, integrated battery disconnect, 100A battery charger, and integrated data monitoring and system control, all in a compact wall-mounted package.
The SI6048-US works with 48Vdc batteries and operates at 6,000 watts AC powwer output to homes that have a single-phase output of 120Vac at 60Hz. Two inverters can be “stacked” to provide 120 or 240V 60Hz split-phase output. Multiple Sunny Island inverters can be combined for up to 20kW of split-phase power, or up to 60kW of three-phase power with an optional multi-cluster box.
The SMA Sunny Island features SMAs off-grid technology and a maximum efficiency of 96 percent ensuring peak production, which reduces diesel usage in rural communities. The Sunny Island inverter provides complete off-grid management, as well as intelligent battery management for maximum battery life. This UL certified solar power inverter is highly durable with an extreme overload capability and comes with a 5 year warranty from SMA.
