Testing & Thermal Performance

Conversion Efficiency at 25°C

Under 500V input:

• Photon reaches 97.23% at 50% load, outperforming both Solis and Growatt.

• Consistently higher across all load levels from 5% to 100%.

Temperature Rise at 45°C

• Photon’s critical components like IGBTs and BUS capacitors showed lower temperature rises, indicating better thermal stability and longer component lifespan.

Hardware Engineering Excellence

Photon’s internal design features:

• Single PCBA layout: Fewer vulnerable connections, improving reliability.

• Optimised heat dissipation: Critical for consistent operation in hot climates.

• Easy diagnosis & maintenance: Simplified internal circuitry.

• EMC Shielding: Less electromagnetic interference.
  

Growatt and Solis rely on traditional multi-PCBA architectures, which may lead to early derating and heat distribution and servicing complications.

Why Choose Photon Solar Inverter?

• Superior Efficiency: Matches or beats the competition under real-world testing.

• Smart Design: Fewer failure points and improved thermal control.

• Durability: IP66 and aluminium alloy construction extend operational life.

• Warranty Confidence: 10-year full replacement—more than just a parts warranty.

If you're investing in a robust, high-efficiency inverter for grid-tied solar systems, the Photon 10kW inverter stands out for its engineering innovation, tested performance, and long-term reliability. Compared to Growatt and Solis, it offers greater efficiency, better heat control, and a more service-friendly build—making it a future-ready solution for sustainable energy systems.
