SMA America (sma-america.com) released two new TL-US models: the 3800TL-US and 6000TL-US.

SMA America (sma-america.com) released two new TL-US models: the 3800TL-US and 6000TL-US. These batteryless string inverters have dual multiple power point trackers and integrated arc-fault protection.

Their secure power supply (SPS) feature allows limited backup capability (up to 1,500 watts) during sunny conditions—without a backup battery bank (see “Backup Power without Batteries” in HP159). With an ambient temperature range of -40°F to 140°F, these inverters can be mounted outdoors, even in cold climates. The inverters have a CEC efficiency of 96.5% at 240 VAC output. The 3,800 W model is suitable for use with a 100 A main service panel. With a 16 A AC output, requiring a 20 A breaker (16 A × 1.25 = 20 A), this inverter is well-matched to the 120% busbar allowance (per National Electrical Code  Section 705.12(D)—see “Code Corner” in HP151).
