SMA-America
4200 Watt Sunny Island Inverter

The Sunny Island 4248U provides a continuous power output of 4200 watts at 25°C and 3400 watts even at scorching temperatures up to 45°C. That's enough power to comfortably energize most household appliances with power to spare. Large loads such as water pumps and refrigerators can be easily powered by the Sunny Island 4248U. This inverter operates silently and can be powered from multiple sources: wind, utility grid (for back-up power), hydro, solar electric and is even compatible with fuel cells. A number of communications options provide flexible remote system monitoring. The optional SMA "GenMan" (generator management box) provides advanced control of even the most basic generators. The Sunny Island 4248U also works in conjunction with grid tied Sunny Boy solar systems to provide a powerful and efficient back up power solution.

The internal battery charger can supply up to 100 Amps to the battery when running in charge mode. Transition from charge to invert mode is a lightning fast 0.02 seconds, so even your computers will stay on-line. A transfer relay with a pass through rating of 56A at 120V is also included. Two Sunny Island 4248's may be paralleled to support 240Vac split-phase load centers. Once installed, the Sunny Island 4248U will run with basically no maintenance for years to come. With its state-of-the-art software and non-volatile memory, just set it and forget it!
