SUNNY ISLAND X

Whether in off-grid areas or connected to the utility grid, the highly versatile Sunny Island X battery inverter supports a wide range of on-grid and off-grid installations.
As a central element of your system, it ensures that self-generated solar energy can be stored and made available at all times. The Sunny Portal powered by ennexOS interface allows you to visualize all the components in the Sunny Island system and monitor the energy flows.
The Sunny Island X ensures the required system flexibility and reliability. The broad temperature range ensures, for example, that the Sunny Island X can operate even under the most extreme conditions – desert heat, tropical humidity or snowy conditions are never a problem for Sunny Island X. Intelligent load and energy management keeps the system running, even in critical situations.
The Sunny Island X is a highly robust battery inverter − and comes with an up to 10-year warranty 2)
The next generation of battery inverters
The Sunny Island X ensures that self-generated solar power is stored and made available at all times, whether in remote off-grid areas or on the utility grid. It is extremely versatile and ideal for both on-grid and off-grid installations.
The Sunny Island X impresses with its exceptional flexibility. Its modular design allows you to adjust the AC power and battery capacity of your system to meet your specific needs. Thanks to the integrated DC-to-DC converter, the Sunny Island X is compatible with a wide range of batteries, offering great flexibility in energy storage. In off-grid installations, generators or the utility grid can also be used as an energy source, when combined with the Sunny Island X Connection Box1). It delivers full power, even at extreme ambient temperatures up to 45 C.
Made to the highest quality standards in Germany, the Sunny Island X guarantees reliability and durability. In on-grid systems, the inverter improves energy management and ensures efficient use. The Sunny Portal powered by ennexOS interface allows you to visualize all the components in the Sunny Island system and monitor the energy flows. The flexible and robust battery inverter Sunny Island X offers you both energy reliability and independence.
