The new SMA Sunny Tripower TL-US is a sophisticated three-phase transformerless inverter. It is UL listed for up to 1000 Volts DC maximum system voltage and has peak efficiency above 98 percent. It is an inverter suitable for both 600 Volts DC and 1,000 Volts DC applications. The Tripower inverters feature OptiTrac Global Peak that will ensure minimum shading effects, maximizing overall system performance.
This Sunny Tripower inverter includes a SWDM-US10 data module and comes with full grid management, communications and monitoring features. The Sunny Tripower is equipped with all-pole ground fault protection and a integrated AFCI for a safe electric installation to meet the requirements of NEC 2011 690.11. It offers a wide input voltage range and two independent MPP trackers.
Note: The SMA CU1000-US-10 connection unit is sold separately and is not included with Sunny Tripower inverters.

SMA America started in Germany in 1981 and is a pioneer in photovoltaics power conversion. Today they are the number one inverter manufacturer worldwide with presence in 15 different countries, including the United States and Canada. In 2011 they opened the solar academy in California to help installers understand SMA’s technology and bring that knowledge to the home of thousands of homeowners in the US.
SMA staples include the Sunny Island inverters for off-grid and remote applications and the Sunny Boy inverters for residential and small commercial applications. In recent years they added the Tripower line of commercial inverters ranging from 12kW to 30kW per unit. Some of their inverters are assembled in Colorado and qualify for the ARRA Recovery Act. All their units are UL listed and comply with the most recent requirements in the National Electric Code (NEC).
SMA America has raised the bar in the solar industry for over 30 years and they continue to do so. They cover a wide range of applications and system sizes. The new inverter models with grid-tie applications come with multiple MPPT channels that will provide increased flexibility for your design and the length of you PV strings. This is a required feature when working with challenging roofs such as odd shapes or significant shading.
Additionally, SMA provides their Sunny Portal free of charge to SMA users. It is one of the most advanced energy communication platforms; all SMA inverters can transfer production data to the Sunny Portal. The portal is accessible to system owners via the Internet, where they can view and monitor their system’s performance in great detail.
