Use to power 240 volt appliances on 120 volt inverters. Indoor enclosure, steel white powder-coated. Maximum load 4.5 kilowatts. Consumes 12 watts at idle. Includes 2 pole 25 amp QOU circuit breaker/disconnect and has room for 3 other QOU AC breakers. #14 to #2 hookup wire size. Dimensions: 6.3" x 21" x 7". UL listed ---------------------------------------------------------------------------------------------------- SUNNY ISLAND 4248U The Sunny Island SI 4248U provides a continuous power output of 4200 watts at 77°F (25°C) and 3400 watts even at scorching temperatures up to 113°F (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 SI 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 Sunny Island SI 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 batteries 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 SI 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! Features: Simple design of island grids by modular coupling of all components on the AC current side Decrease of the system costs Very high efficiency (up to 95%) Optimal battery durability via intelligent battery, load and island management Connection and disconnection of consumers or other energy sources, depending on the batteries charging state Safe power supply in grid quality Any parameters free configurable Load depending connection and disconnection of generators Visualization of the batteries charging state and of the current battery capacity Compatible with SMA Sunny Boy inverters and with the Sunny Boy communication for plant monitoring and remote diagnosis AC coupled island systems for off-grid electricity supply of areas without public utility The Sunny Island is based on advanced power electronics and state-of-the-art DSP microprocessor technology. A Sunny Island system is simple to use, flexible and easy to extend. It is suitable for off-grid systems as well as a utility backup. SMA also offers so-called "System Kits" in addition to the Sunny Island. System kits are off-the-shelf packages with selected components such as battery banks, generators, cabling etc. The system kits make the installation and assembly of off-grid systems easier then ever. Flexible The Sunny Island battery inverter is the heart of your off-grid electricity supply. The Sunny Island combines all components of your plant on the AC side and forms the grid. Modular and simple Off-the-shelf and affordable AC components can be connected to your AC island grid. These can be "normal" electricity sources such as Sunny Boy PV-inverters as well as any known household device. Expensive DC cabling on the consumer side of your island grid is not necessary. Compatible The Sunny Island is designed for extreme surge power capability. The Sunny Island can generate 3 to 4 times the nominal power for a short period of time in order to start electric motors or the like. The Sunny Island product range is naturally compatible with the Sunny Boy plant monitoring systems and can therefore be integrated into nearly any monitoring system. The available monitoring systems range from simple data acquisition on site all the way to integration into web based monitoring using the Sunny Portal. Easily extendable An off-grid system based on Sunny Islands is ready for nearly any kind of modification. The coupling on the AC side allows you to install additional sources which can be Sunny Boy PV-inverters or CHP power plants. Off-grid systems with the Sunny Island 4500 can be extended from simple single-phase island grids to a 3-phase grid with several Sunny Islands. And this can be done step by step, depending on your increasing energy demand. Powerful Off-grid systems with Sunny Islands are powerful for two reasons: The coupling of the components on the AC side results in an adding up of all energy sources. A high solar radiation results in a high output of your Sunny Boy inverters while this energy is additionally available to the power your Sunny Island can deliver. This increases the total power of your plant. Place a Bid!
