Ultimate Cooling for Maximum PV Efficiency High-Reliability Thermal Solutions for the PV Industry

As the core link between PV modules and the grid, the performance and reliability of inverters directly determine the ROI of a solar power plant. Winshare Thermal provides high-performance, cost-effective thermal solutions designed specifically for PV inverters, ensuring your equipment operates continuously, efficiently, and stably throughout its 25-year design life.

Core Thermal Challenges for PV Inverters

High-Temperature Power Losses

IGBT/SiC modules in inverters are major heat sources. Their lifespan is nearly halved for every 10°C rise in temperature. Efficient cooling is fundamental to ensuring non-derated operation and a 25-year lifespan.

Harsh Outdoor Environments

PV plants are often built in deserts, mountains, or on water. Inverters must withstand long-term erosion from extreme heat, humidity, salt spray, and sand.

High IP Protection Ratings

To cope with rain and dust, string inverters typically use fanless, natural convection cooling, requiring the heat sink itself to have a high IP rating (IP65+).

Extreme Cost-Effectiveness

The PV industry is extremely cost-sensitive. Thermal solutions must offer highly competitive costs while ensuring performance and reliability to help clients achieve grid parity.

Customized Solutions for All PV Inverter Types

We offer a full-process portfolio from air to liquid cooling, from extrusions to die-casting, to precisely meet the diverse needs of central, string, and residential inverters.

Simulation-Driven Design

Optimizing air/fluid channels through simulation to achieve the best cooling effect at the lowest cost.

Our Success Stories

We work closely with the world's leading PV inverter manufacturers, helping their products succeed globally.

Developing String Inverter Heat Sinks for a Global Top 3 Client

Challenge: The client's new 200kW+ inverter needed a 30% power increase in the same volume, while meeting C5 corrosion resistance.

Solution: We optimized the fin design through simulation and used a high-conductivity die-cast aluminum alloy with a special surface treatment.

Result:Thermal performance increased by 25%, weight was reduced by 10%, successfully helping the client capture the high-power string market.

Enabling Central Inverters for Floating PV Plants

Challenge: The high-humidity, high-salt-spray environment of floating PV projects posed an extreme reliability challenge for inverter cooling systems.

Solution: We provided an IP68-rated forced air cooling module with heat pipes and a fully sealed design.

Result:The product passed a 1500-hour enhanced salt spray test and has been operating without failure in multiple floating PV projects for over 5 years.

A Cost-Effective Solution for Residential Hybrid Inverters

Challenge: A client's residential hybrid inverter required a heat sink that was aesthetic, silent, and extremely cost-competitive.

Solution: We designed an extrusion heat sink with an artistic fin structure and significantly reduced costs through process optimization.

Result:While meeting all performance requirements, we reduced the client's cooling cost by 20%, leading to an order of several million units.
