The WECO 4k4 LT is a compact yet powerful Lithium Iron Phosphate (LFP) solar battery designed to meet the high-demand needs of residential, commercial, and industrial off-grid or hybrid solar systems. With a 4.4kWh capacity and up to 6,000 charge cycles, it guarantees long-lasting and efficient energy storage with low maintenance.
What sets the 4k4 LT apart is its impressive 95% Depth of Discharge (DOD)—giving users nearly the full capacity for use without compromising battery health. This translates into more usable energy per charge, lower operational costs, and excellent return on investment.
The system architecture is built for scalability: connect up to 15 units per cluster, and expand up to 8 clusters, enabling a total storage capacity ranging from 67.5kWh to 472.5kWh. Whether you’re running a remote facility, a backup system, or a full off-grid power solution, the 4k4 LT offers unmatched flexibility.
Its smart BMS allows for stable performance, load balancing, and protection, while its robust LFP chemistry ensures safety, thermal stability, and a long lifespan—making the WECO 4k4 LT a reliable choice for smart solar storage at any scale.
