The SMA Sunny Island 6048-US inverter is based on the proven off-grid technology in the Sunny Island 5048-US but now features 20 percent more power output. The maximum efficiency of 96 percent ensures peak production, which results in reduced diesel usage and makes a smaller dimensioning of the PV array possible. With Multicluster technology, up to 12 Sunny Islands can be integrated into off-grid power systems up 100 kW in size.

Use the 6048-US with any grid-tied system for on-grid battery backup or off-grid AC power.

For Grid-Connected Applications
Sunny Island can be added to any existing grid-tie system or even for backup power during power outages. Normally, a grid-tied inverter will shut off during a power outage, leaving you without power. With a complete Sunny Island system, the grid-tie inverter supplies AC power from a solar panel array to charge a battery bank. The Sunny Island reliably supplies power for loads and intelligently monitors and charges battery banks with the energy from local AC sources such as solar, wind or gensets connected on the AC side.

For Off-Grid Remote or Island Power Applications

Featuring sophisticated generator management and true battery state of charge control, the Sunny Island can control a diesel generator connected to it in an extremely fuel-efficient manner.

The SI6048-US inverter can be integrated into a public grid or island power grid. This grid can be connected by solar microgrids powered by Sunny Boy PV inverters that are distributed anywhere along the AC grid.

Sunny Island can be programmed to deactivate loads automatically if the battery is unable to provide sufficient power. This reduces the risk of damage to the battery bank.

The redundant design of SMA’s AC and DC coupling technology and expandability of the Sunny Island-based solar systems assure the highest reliability and flexibility.

Sunny Island inverters are robust hard-working inverters yet are also designed for regular partial load operation. Sunny Island has extremely low open-circuit and standby consumption which results in longer battery life, smaller required solar panel array size and reduced diesel usage in rural communities.
