Solis launches new line of 1500V string inverters
Solis, recently ranked No. 1 in residential inverter shipments globally, is also beefing up its large-scale solar product offering, launching a new 1500V line of string inverters in North America. The new Solis S6 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.
“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. “The addition of the 250-350kW product family with it’s higher power output, lower costs, and enhanced safety standards, has exceeded customer expectations. We’re proud to serve a wide range of applications in demanding environments, including tidal flats, and mountainous regions.”
As evidence of its capabilities, Wang points to 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.
The Solis 250-350K is available now, with deliveries starting in Q4 2024.
Solis S6 250-350K overview
This 1500V inverter line, integrating Solis’ proprietary MPPT algorithm, has surpassed the 99% efficiency threshold, according to the company. The 250-350K comes in power classes of:
- 250kW @600VAC,
- 300kW @ 690VACand
- 350kW @ 800VAC
A broad range of DC and AC voltages makes the Solis S6 250-350K 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.
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 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.
Check out the entire turnkey solution on display at RE+, September 9-12, 2024 in booth #B47008.
