Collection: SMA Sunny Island Inverters

The Sunny Island 6.0H / 8.0H supports a wide range of on-grid and off-grid applications

Install large off-grid systems with minimum effort. The Multicluster-Boxes for the Sunny Island inverters are the ideal solution for the easy installation of island and hybrid systems from 30 up to 300 kW. They include integrated generator and load shedding contactors for AC distribution. For an example of Multi-cluster boxes in use see Isle of Eigg project.

Used in conjunction with the Sunny Island Multicluster box SI-MC-BOX-12.3.20 to enable use in connection with the grid for self-consumption or battery back-up systems.

Double pole circuit breakers. These protect the DC cables between batteries and inverters against overcurrent and short-circuit and allow easy isolation for installation or maintenance of the inverters.

Allows disconnection of loads in event of low battery state of charge. Controlled by signal from programmable relays inside the Sunny Island inverter.

An automatic transfer switch, suitable for the SMA 'Flexible Storage System' which allows operation to continue in case of main power blackouts. Contactors ensure compliant earth switching.

Used with the Master inverter of each cluster with lead acid batteries to ensure correct battery charging.

Sunny Island Accessories for older model Sunny Island inverters

Used to measure DC current when there are loads or charge sources directly connected to the battery. Allows the Sunny Island inverters to include these in it's state of charge calculations and ensure accurate battery charging.

Suitable enclosure for the SMA Sunny Island Load Shedding Contactor SI-LS100-48.

The SMA Sunny Island X represents their next generation of battery inverters. Suitable for multiple applications on-grid and off-grid the SMA Sunny Island X is extremely versatile.
