Sunny PRO Club Members Catch First Glimpse of Residential Transformerless Inverters

Sunny PRO Club members were recently invited to participate in the limited launch of the highly anticipated Sunny Boy 3000TL-US/4000TL-US/5000TL-US inverter series. The new Sunny Boy TL-US series represents the next step in performance for residential solar inverters. The inverter’s impressive features include a dedicated emergency power supply, dual MPPT trackers, flexible design capabilities, high efficiency and reduced weight. 

The Selection Process

The Sunny Boy 3000TL-US/4000TL-US/5000TL-US limited launch was open exclusively to members of SMA’s partnership program, the Sunny PRO Club.  Members were invited to submit applications and a small group was then selected to receive initial production units of SMA’s newest, feature-packed inverter.

Valuable Field Feedback 

The vital information collected from this initial launch will help SMA ensure the inverters are performing at their best and are ready for widespread distribution to the North American market in the coming months. Installers were enthusiastic about participating and have been impressed with the variety of advantages the next generation Sunny Boy possesses.

“The new SMA Sunny Boy TL inverter really sets itself apart from other grid-tied inverters on the market. It’s easy to install, has a favorable DC input range with dual MPPT, and the emergency power supply option is a revolutionary step forward for the solar industry. I am proud to be a partner with    SMA and excited to have a role in the TL’s limited launch program.” Orion Thornton of Onsite Energy

The Sunny PRO Club

The Sunny PRO Club started in 2008 and has since evolved into a one-of-a-kind technology partnership between SMA and solar installers. This partnership gives a core group of installers a competitive edge by giving them access to the latest SMA technology before it is available to the rest of the U.S. market.

The SMA limited launch program is example of the many benefits of Sunny PRO Club membership. For more information on how to become a Sunny PRO Club member visit
