SMA Sunny Tripower TL-US inverter promises high efficiency
By Anthony Capkun
July 23, 2013 – SMA has released its Sunny Tripower TL-US to the North American solar market. (CHECK OUT video below) This 3-phase, transformerless inverter is suitable for decentralized commercial photovoltaic plants, and is available in 12kW, 15kW, 20kW and 24kW models. UL listed for up to 1000vdc, the inverter promises peak efficiency of more than 98%, while its OptiTrac Global Peak maximum power point (MPP) tracking algorithm further maximizes energy production by minimizing the effects of shade. Safety and reliability have been enhanced, says SMA, due to the inverter’s all-pole ground fault protection, integrated AFCI, reverse polarity indicator and DC monitoring per MPPT (granular down to four strings).
