TLC Series Three-phase string inverters are designed for residential, small industrial and commercial, and poverty alleviation power stations. With a maximum conversion efficiency of up to 98.8%, single-string input current increased to 30A, and voltage elevated to 1100V, they are fully compatible with various high-efficiency modules and bifacial modules, optimizing system design to enhance returns. The algorithm is further optimized, offering robust weak grid support and more stable grid connection.
