The Island Manager.
The Sunny Island 5048 is a bidirectional inverter (battery inverter and charger) for stand-alone systems. The Sunny Island supplies consumers on the stand-alone grid side and charges battery banks with the energy from grid-feeding units connected on the AC side.

The comfortable support of AC and DC coupling, as well as the expandability of the systems formed with the Sunny Island guarantee highest flexibility. In addition, innovative technology allows the Sunny Island to achieve a maximum efficiency of more than 95%. Due to the high overload capabilities and the integrated output management, there is no need to oversize the Sunny Island.

The parallel operation of up to 3 devices on a single phase system or 3 devices on a three-phase system enables the Sunny Island to be used to set up stand-alone grid supply systems with output power of 3kW - 26 kW. Thanks to its sophisticated generator management, it can control connected diesel generators in a particularly gentle and fuelsaving manner. The power distribution grid can also be integrated. The Sunny Island can also deactivate loads automatically if the battery does not provide sufficient electrical energy.
