May 16, 2013 | By Anthony Capkun

May 15, 2013 – SMA is now taking orders for its transformerless inverters designed specifically for the North American market: Sunny Boy 3000TL-US, 4000TL-US and 5000TL-US. The residential inverters promise “maximum energy production, flexible design, simple installation, and advanced communication and monitoring control”. The inverter’s Secure Power Supply function makes it possible for the inverter to provide up to 1500W of daytime standby power in the event of a grid outage. The transformerless design of the new Sunny Boy promises high efficiency and reduced weight, while a “simplified” DC wiring concept allows the DC disconnect to be used as a wire raceway, saving labour and material. TL-US series includes an optional plug-n-play Webconnect data module for system monitoring and direct data transmission from Sunny Portal. Communications via ZigBee is also available, laying the groundwork for integration with future home energy management systems.
