The Sunny Boy 3000TL-US / 3800TL-US / 4000TL-US / 5000TL-US / 6000TL-US / 7000TL-US / 7700TL-US PV inverters with UL listing offer that little something extra when it comes to performance. What makes them unique is their ability to supply smaller household appliances with power during the day in the event of a grid outage via an extra outlet. Simultaneously, a high degree of efficiency and a very broad operating temperature range ensure that power is used to its maximum advantage. Thanks to OptiTrac™ Global Peak and its multistring technology with a broad input voltage range, the Sunny Boy TL-US is especially flexible when it comes to system planning, even in combination with demanding PV arrays and partially shaded systems. It is no wonder that the PV inverters in the Sunny Boy TL-US series are setting performance standards and leading the way in technology for private residential PV systems.
