When Jiangsu's Football Fever Meets the PV Race: The "Football Philosophy" in New Energy Step-Up Substations Part 1

This summer, a new catchphrase has emerged on the streets of Jiangsu—"Did you catch the game today?" From the loudspeakers in community squares to elevator screens in office buildings, from the clinking glasses in sports bars to the sizzling skewers at night markets, the fever of the "Jiangsu Football League" has swept across the province like the scorching buzz of cicadas in summer, even igniting the "social media feeds" of fans nationwide.

Football fans often say, "A great team's soul lies in its style of play, and its confidence comes from its roster." When the camera pans across the pitch—capturing the striker cramping up for that one crucial goal or the defender bruised from guarding the net—you understand what "competitive spirit" truly means: perfecting every detail, honing seamless teamwork, and at critical moments, delivering high-value performance that makes the audience cheer for the grit.

This philosophy aligns surprisingly well with the new energy sector.

When the "key player" steps onto the photovoltaic stage: Why is the power conversion station the "midfield maestro" of new energy?

On the "battlefield" of distributed and commercial-industrial solar power, a 5.9MW photovoltaic array stretches like a blue ocean, a 4.5MW rooftop power station stands as an urban "energy forest," and a 3MW commercial-industrial project hides atop factory buildings as a "power generator." But for these "energy matrices" to truly integrate into the grid and reach millions of households, they must pass through a critical "checkpoint"—the photovoltaic step-up box-type substation.

It’s much like the midfield playmaker on a football pitch: on one end, it connects to the PV array (the 0.8kV "energy source"), and on the other, it outputs high-voltage current (the 10.5kV "energy artery"). It’s not just the hub of energy conversion but also the "anchoring force" ensuring the system’s stable operation. Put simply, in the total cost of a PV system, the substation often accounts for 15%-20%—choosing the right one is like installing a "cost-saving engine" for the entire project, while the wrong choice could mean "one wrong move ruins the whole game."
