SMA Sunny Island 5000 Watts 48 Volts Power Inverter

Manufacturer Part Number: 5048-US

The Sunny Islands offer you first class possibilities in the installation of self-sufficient energy systems. In conjunction with a battery pack the devices form a self-sufficient AC voltage grid, which meets with the highest of quality standards.

In the Sunny Island System, electricity generators and consumers are integrated in equal measure. PV and wind energy systems, diesel devices, water or CHP (Combined Heat and Power) can be coupled on the AC side just as conventional 230 Volt consumers.

Thus the Sunny Islands offer you two decisive advantages: at system planning and layout you can enjoy the highest degree of flexibility, during installation the complex DC cabling is not required.

Specifications

Detailed Description

Overview

The Sunny Island 5048U is a bidirectional inverter (battery inverter and charger) for stand-alone systems. The Sunny Island 5048U supplies loads on the stand-alone grid side (protected loads panel) and charges battery banks with power that is provided by a wide range of AC or DC sources simultaneously. The Sunny Island 5048U can manage AC power sources that are coupled on the AC input/output side, a direct input from a generator or utility, or a DC power source that is coupled to the DC input/output side. The ability to support AC and DC coupling, and the wide variety of system configurations supported make the Sunny Island 5048U the most flexible inverter/charger available today.

Industry Leading Efficiency

Thanks to innovative SMA technology, the Sunny Island 5048U achieves a maximum efficiency of more than 95 %. Optimized for operation under partial load, the efficiency peaks at about 15 % of rated power and remains high throughout the power curve. The Sunny Island 5048U also features very low consumption when idle or in standby mode. Due to the high overload capabilities and the integrated output management, there is no need to oversize the Sunny Island.

Multiple Grid Configurations Supported

The Sunny Island 5048U supports parallel operation of up to four inverters on a single phase system, up to four inverters on a split phase system, or three invertes on a threephase system. This flexibility enables the Sunny Island 5048U to setup stand-alone power supplies with outputs ranging from 3 kW to 26 kW. Please refer to the example system diagrams on pages 17 and 18.

Automatic Generator Control

The Sunny Island 5048U can automatically start and stop the generator depending on battery state of charge or consumer power demands. The Sunny Island 5048U will also protect the generator from overloading by limiting the amount of current it draws based on the GnCurNom parameter setting. The Sunny Island 5048U can also provide up to 5 kvar of reactive power in the generator/grid circuit depending on battery SOC and AC load requirements to improve generator/grid power factor.

Sophisticated Battery Management

The intelligent battery management precisely records the battery's state of charge. This enables improved utilization of battery capacity, which also means that smaller, more cost-effective batteries can be used without affecting performance. In order to prevent premature aging caused by incorrect charging and frequent deep discharge, the Sunny Island 5048U has an intelligent charge control and reliable deep discharge protection.When these functions are properly used, the battery service life can be greatly extended in comparison with simpler devices. The Sunny Island 5048U can also automatically shed less critical loads to extend availablity when off grid.

Easy Installation, Configuration

Despite the complex function of this battery inverter, the Sunny Island 5048U is easy to configure. All the settings required for operation can be quickly and easily programmed in ten steps using the "Quick Configuration Guide". In a system with multiple Sunny Islands, the system is programmed and operated using a "Single Point of Operation". The system/cluster parameters are only set on the master device, and all other devices automatically adopt the configuration. The easy-to-understand menu navigation allows quick access to all important data, even while the system is running.

Integrated Data Logging

An MMC/SD card allows storage of system parameters, data acquisition, event logging, and is extremely valuable when trying to determine the cause of error messages.
