Used product. The SMA Sunny Boy SB 5000TL-20 is a high-quality single-phase grid-connected photovoltaic inverter designed for residential and small commercial solar installations. Developed by SMA Solar Technology AG, it features advanced Transformerless technology that delivers excellent energy conversion efficiency, outstanding operational reliability, and maximum flexibility in photovoltaic string management.
Equipped with two independent MPPTs (Maximum Power Point Trackers), the inverter allows separate management of two photovoltaic strings with different orientations or tilt angles, maximizing energy production even under partial shading conditions. Its wide MPPT voltage range provides exceptional flexibility when designing photovoltaic systems of various configurations.
The IP65 protection rating makes the inverter suitable for both indoor and outdoor installations, while the high-efficiency passive cooling system ensures silent operation and reduced maintenance requirements over its service life. The integrated LCD display provides convenient real-time monitoring of the inverter's main operating parameters and system status.
