SMA TL-US Inverters with Standby Power Supply

SMA America (sma-america.com) released its new line of Sunny Boy batteryless inverters. Built for the North American PV market, the transformerless inverters are available in 3, 4, and 5 kW models. The inverters include a “secure power supply” dedicated AC outlet, delivering up to 1,500 watts in daylight during a grid outage—without needing a backup battery bank.

Features include an extended operating temperature range (-40°F to 140°F), which is helpful for systems requiring outdoor inverter mounting, and two maximum power point (MPP) trackers for combining arrays mounted in two different orientations. With a DC input operating range from 125 to 600 V, these inverters offer a wider input voltage range than their predecessors. An integrated arc-fault circuit interrupter (AFCI) meets the 2011 National Electrical Code section 690.11. Inverter CEC efficiency is listed at 96.0% to 96.5%.
