Transformerless residential inverter

SMA’s Sunny Boy 3000TL-US/4000TL-US/5000TL-US inverters are a new, residential solution, featuring maximum energy production, flexible design, simple installation, and advanced communication and monitoring control. The inverter’s Secure Power Supply function is also an industry first, providing daytime power in the event of a grid outage. The transformerless design of the new Sunny Boy ensures high efficiency and a reduced weight. A simplified DC wiring concept allows the DC disconnect to be used as a wire raceway, saving labor and material. It’s tested to UL 1741 and 1699B standards, and has integrated AFCI, meeting NEC 2011 690.11 arc fault requirements. With leading CEC efficiencies, a wide input voltage, and extended operating temperature ranges from -40° F to 140° F (-40° C to 60° C), the TL-US series offers maximum power production under a variety of conditions.
