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.
As a voltage source, the Sunny Island inverter forms the stand-alone grid. The Sunny Island inverter regulates the balance between the energy that is fed in and the energy that is used and features a battery, PV array and load management system.
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.
With lithium-ion batteries, this ampacity cannot be taken for granted. • Check with the battery manufacturer whether the battery is suitable for off-grid systems with Sunny Island inverters.
Off-grid systems with Sunny Island inverters are self-sufficient utility grids that are being fed with energy from several AC sources in the stand-alone grid (e.g., PV inverter), from a generator, and/or with DC charge controllers (e.g., Sunny Island Charger). The Sunny Island forms the stand-alone grid as a voltage source.
The Sunny Island is not suitable for supplying life-sustaining medical devices. A power outage must not lead to personal injury. Several Sunny Island inverters can be operated in an off-grid system. Three Sunny Island inverters are connected in parallel on the DC side and form a cluster.
