Solis announced the launch of a new 1,500-V line of string inverters in North America — the Solis S6 250-350K. The power classes available within this family are 250 kW @ 600 VAC, 300 kW @ 690 VAC and 350 kW @ 800 VAC, providing many options for repowering and new development of large-scale systems. This solution, integrating Solis’ proprietary MPPT algorithm, has surpassed the 99% efficiency threshold, offering greater reliability and output to solar power station owners.
With a broad DC and AC voltage range and increased flexibility in design and string sizing, the 250-350K is ideal for challenging environments and repowering. The current ratings, up to 16 MPPTs and fuse-free design can potentially increase yield while reducing costly operations and maintenance. As a result, system owners and operators can accelerate return on investment on large-scale systems.
The 250-350K features advanced string technology that addresses key challenges faced by professionals using central systems by enhancing redundancy and modularity, supporting overall system uptime. Remote I-V curve scanning and firmware updates enable swift issue resolution from any location. Installation and expansion are simplified and cost-effective, thanks to integrated MC4 pigtails and supported “Y” connectors improve conductor utilization within the array and reduce DC runs. PLC Communications reduces the requirement for expensive and labor-intensive communication cables. Additionally, the 250-350K is compatible with the Solis-4200-MV Skid Solution and AC Combiner box for a turnkey solution that streamlines deployment.
“The Solis 250-350K inverter is not just an incremental upgrade; it’s a giant leap forward in utility-scale solar technology,” said Jimmy Wang, president of Solis Inverters. “Our 1500-V inverter has a proven track record, as demonstrated in a 1-GW project in Ningxia, which is expected to produce 20 billion kilowatt-hours of clean electricity per year, reducing carbon dioxide emissions by approximately 16 million tons.”
Available now, with deliveries starting in Q4 2024, the Solis 250-350K inverter is poised to lead the transition to string inverter technology in large-scale solar projects across the United States and Canada.
