SMA Sunny Island inverters are based on the same proven inverter technology the brand is known for. The Sunny Island 4548-US is an off-grid inverter boasting an impressive 96% maximum efficiency and is a complete power system capable of handling critical loads as well as intelligently managing your batteries.
- 96% efficiency
- Able to control connected diesel generators
- Expandable to power up to 100 Kw
- Intelligent charge control to extend battery life
- Perfect for off-grid or grid backup systems
Up to 12 Sunny Island units can be connected together to create an off-grid system up to 100kW providing continuous reliable power to your home. Combining the SI 4548-US with a generator allows for back-up battery charging.
When a Sunny Island unit is coupled with a Sunny Boy grid-tie inverter the system becomes an AC coupled system, allowing your PV array to power your loads, charge your battery bank, and feed excess power back to the grid.
